US' new power generation system patented, uses energy fluctuations
Researchers from the Southwest Research Institute (SwRI) and 8 Rivers have patented a cost-effective power generation system that leverages fluctuations in energy demand by using liquid oxygen storage (LOX) to enhance power plant efficiency and reduce costs. The system modifies the Allam-Fetvedt Cycle, a power cycle that combusts fuel with an oxygen and carbon dioxide mixture to enable complete carbon capture and minimal greenhouse gas emissions. By generating oxygen during off-peak hours when electricity prices are low, storing it in liquid form, and using it later during peak demand, the system boosts plant output while lowering operating costs. SwRI conducted a techno-economic analysis modeling plant performance and hourly costs over a year, confirming the system’s profitability amid increasing electricity price volatility driven by rising renewable energy penetration. As renewable energy sources like wind and solar increase to 30% or more of the grid, energy storage becomes critical to managing fluctuations. The patented LOX storage offers a large-scale energy storage solution by producing liquid oxygen when

The article highlights a large-scale carbon removal initiative in Brazil, where a Manhattan-sized basalt field is being used as a live testbed for Enhanced Rock Weathering (ERW). Led by the carbon removal company Terradot in partnership with Microsoft, the project accelerates the natural process by which silicate rocks capture atmospheric CO₂. Finely milled basalt is spread on farmland, where it reacts with rain and soil to form bicarbonate, effectively storing carbon in dissolved form. Brazil’s favorable climate, renewable energy availability, and abundant basalt resources make it an ideal location for this approach. Over the past year, Terradot has applied over 100,000 tonnes of basalt across 4,500 hectares, aiming not only for carbon removal but also to provide agronomic benefits to farmers. Microsoft supports the project beyond funding, contributing technical expertise and backing Terradot’s rigorous measurement and verification efforts. Central to the initiative is the Sentinel research site in São Paulo state, which monitors carbon’s journey from

Deep Sky, a Canadian company, plans to build one of the world’s largest carbon removal facilities in southwestern Manitoba, with an expected annual capacity of 500,000 tons of CO₂ removal at full scale. Construction will begin in 2026 with an initial phase targeting 30,000 tons, representing an investment exceeding $200 million. The project is supported by the Dakota Grand Council and aligns with their long-term economic development strategy focused on sustainability. Southwestern Manitoba is considered an ideal location due to its suitable geology for underground CO₂ storage, recent provincial legislation enabling such storage, and access to clean hydroelectric power essential for low-emission direct air capture (DAC) technology. The facility is anticipated to bring significant economic benefits to the region, including construction and operational jobs, opportunities for local businesses, and indirect economic growth. Manitoba’s government emphasizes the project’s role in advancing industrial innovation and climate leadership, positioning the province among a select group globally capable of hosting large-scale carbon removal infrastructure.

The 2025 Nobel Prize in Chemistry has been awarded to Susumu Kitagawa, Richard Robson, and Omar M. Yaghi for their pioneering development of metal–organic frameworks (MOFs). These crystalline materials are constructed by linking metal ions with organic molecules to create highly porous structures with vast internal surface areas. MOFs can trap, store, and manipulate gases and molecules, enabling applications such as capturing greenhouse gases, purifying water, catalyzing chemical reactions, and storing hydrogen fuel. The Royal Swedish Academy of Sciences highlighted the trio’s work as transformative for materials science, opening new avenues for clean energy and environmental sustainability. The origins of MOFs date back to 1989 when Richard Robson first assembled copper ions with organic molecules into crystalline frameworks, although early versions were unstable. Susumu Kitagawa later demonstrated the frameworks’ flexibility and gas absorption capabilities, while Omar Yaghi engineered the first highly stable MOFs and introduced rational design principles. These principles allow chemists to tailor MO

Researchers at the University of Sharjah in the UAE have developed and patented a novel technology that transforms spent coffee grounds (SCG) from Starbucks in Dubai and polyethylene terephthalate (PET) plastic waste into high-performance activated carbon for carbon dioxide (CO2) capture. This innovation addresses two critical environmental challenges simultaneously: reducing industrial CO2 emissions and managing large volumes of waste. The process involves co-pyrolysis of coffee and plastic waste at 600°C with potassium hydroxide (KOH) as an activating agent, producing a material with strong CO2 adsorption capacity suitable for industrial applications. This dual-purpose technology leverages abundant waste streams—over 10 billion kilograms of coffee waste and millions of tons of PET plastic produced annually—to create an economically viable and sustainable solution for carbon capture. The activated carbon produced can effectively adsorb CO2 from fossil fuel-based energy systems, helping mitigate air pollution and climate change. The researchers emphasize the environmental, social, and economic benefits of repurposing these

The Stratos facility in West Texas is set to become the world’s largest commercial-scale direct air capture (DAC) plant, aiming to begin operations by the end of 2025. Designed to capture 500,000 tonnes of CO2 annually—about 14 times the capacity of the current largest DAC plant in Iceland—Stratos represents a critical test of whether DAC technology can be scaled beyond pilot projects. DAC is a cutting-edge carbon removal method that extracts CO2 directly from ambient air, which contains CO2 at a very low concentration (~0.04%), requiring the processing of massive volumes of air through chemical systems that bind and then release concentrated CO2 for underground storage. DAC differs fundamentally from traditional carbon capture and storage (CCS), which captures CO2 from concentrated emission sources such as power plants. Because atmospheric CO2 is roughly 1,000 times more dilute than point-source emissions, DAC systems must handle much larger air volumes, resulting in higher energy use, costs, and engineering challenges

The Department of Energy (DOE) under the Trump administration recently canceled approximately $9 billion worth of awards, a move publicly framed as prioritizing fossil fuels over renewable energy. However, documents obtained by TechCrunch reveal a more nuanced picture: the cancellations affected a broad range of projects, including some aimed at reducing methane emissions in oil and gas operations and carbon capture initiatives. Notably, the Gas Technology Institute, which serves the natural gas industry, had $417 million in awards canceled, and carbon capture projects lost around $200 million. The cancellations disproportionately impacted states that voted for Kamala Harris in the last presidential election, with California losing over $2.2 billion and other blue states like Colorado, Illinois, and New York also facing significant cuts. In contrast, states that voted for Trump saw far smaller losses. Several large-scale projects were among those canceled, including a $1.2 billion award to Minnesota intended to modernize electrical grid interconnections across seven Midwest states, potentially unlocking 28 gigawat

Thomas Brück, PhD, head of the Werner Siemens Chair of Synthetic Biotechnology at the Technical University of Munich (TUM), is pioneering the use of algae to capture carbon dioxide and produce sustainable alternatives to fossil fuels, including jet fuel. With a background spanning the UK, US, and Germany, Brück combines academic research and industry experience to develop scalable, biology-based solutions for a net-zero economy. His work, supported by significant funding from the Werner Siemens Foundation, focuses on engineering smarter materials and rethinking the construction industry’s role in climate change mitigation. Brück’s interest in algae began during postdoctoral research on marine microorganisms and their biosynthetic pathways. Recognizing algae’s potential to remediate CO2 and generate valuable microbial oils, he founded the AlgaeTec Center at TUM in 2015. This unique facility enables flexible, scalable algae cultivation under realistic climate conditions, developed in collaboration with industry partners like Airbus, which is interested in converting algae-based oils into aviation fuels.

energysustainable-materialscarbon-capturesynthetic-biotechnologyalgae-cultivationbioengineeringclimate-change-solutionsWhy carbon capture is the real bottleneck in climate tech
The article highlights that while carbon storage capacity is expanding and technologically ready, the primary bottleneck in climate tech lies in the insufficient rate of carbon capture. Carbon capture and storage (CCS) is a three-step process involving capturing CO2 emissions from industrial sources like power plants, cement, and steel factories, transporting the compressed CO2, and permanently storing it underground. Experts emphasize that CCS is crucial for decarbonizing hard-to-abate sectors and enabling carbon dioxide removal technologies such as Bio-Energy with CCS and Direct Air Carbon Capture and Storage. However, despite the growing storage infrastructure, the volume of CO2 being captured remains inadequate to meet storage potential. The challenges in scaling carbon capture include high energy consumption, inflexibility with varying industrial loads, expensive infrastructure, and health and safety concerns related to chemical degradation. These factors contribute to slow deployment and limited adaptability of capture technologies, especially for industrial emissions with dilute CO2 concentrations. Both Sarah Saltzer of Stanford Center for Carbon Storage and Jean-

Researchers at Hof University of Applied Sciences in Germany have developed innovative insulation boards made from fungal mycelium, offering a sustainable and compostable alternative to conventional synthetic materials. The project, called Mycobuild, aims to scale production from lab to industrial levels by 2026. These fungi-based boards are grown on substrates made from locally sourced plant residues like dry straw, where fungal networks bind the material into solid panels. Unlike traditional insulation, these boards absorb CO2, resist mold formation, and require less energy to produce, making them environmentally friendly and carbon-storing. One of the main challenges addressed by the team involves controlling fungal growth to prevent contamination and mold, achieved through sterile conditions and careful substrate nutrient balance. To enhance durability and moisture resistance—key factors for commercial viability—the boards are coated with a mineral top layer developed in collaboration with a building materials firm. This coating not only protects against moisture and mold but also increases the material’s strength. The researchers are working toward fully waterproof insulation panels.

DACLab, a startup emerging from stealth mode with $3 million in seed funding, claims it can remove carbon dioxide from the atmosphere using significantly less electricity than many competitors. While direct air capture (DAC) typically requires around 2,000 kilowatt-hours (kWh) of electricity per metric ton of CO2 captured, DACLab reports achieving this at approximately 1,500 kWh per ton, with plans to reduce consumption below 1,000 kWh per ton. Their technology, adapted from an industrial carbon capture system developed at TU Wien in Austria in partnership with Shell, separates the CO2 capture and release processes into different locations, allowing for lower heat requirements (around 70°C) and improved energy efficiency compared to conventional integrated systems. DACLab has built two pilot units capable of capturing 100 metric tons of CO2 annually, priced under $500,000 each, with plans to scale up to units capturing 1,000 and 5,000 metric tons per year.

The Philippine Net Zero Conference 2025 convened on September 18 to address the country’s ambitious goal of reducing greenhouse gas emissions by 75% by 2030. Co-hosted by the Net Zero Carbon Alliance (NZCA) and the Southeast Asia Corporate Decarbonization Exchange (CDx), the event brought together corporate leaders and policymakers to move beyond abstract climate commitments toward concrete, scalable technological and financial solutions for deep decarbonization. Despite legislative progress such as the Low Carbon Economy Investment (LCEI) Act, businesses face challenges including limited access to climate finance, a shortage of scalable technologies, and a lack of appropriate tools. The conference emphasized the urgency of climate action, highlighting the significant economic losses from extreme weather (around ₱200 billion annually) and positioning the green transition as an opportunity for economic growth, job creation, and improved energy security aligned with global ESG standards. A central focus was the advancement of the LCEI Act, particularly House Bill 2184

The article highlights a critical gap between corporate climate commitments and effective carbon dioxide removal (CDR) strategies necessary to achieve global net-zero emissions by 2050. According to a report from the NewClimate Institute, many of the world’s largest companies are relying heavily on short-term, nondurable carbon removal methods such as tree planting and soil carbon storage, which only sequester carbon for decades or a few centuries. In contrast, durable CDR techniques—such as injecting CO2 into geological formations or mineralizing it into rock, which can lock away carbon for at least 1,000 years—remain underutilized and currently represent just 0.1 percent of global carbon removal efforts. The report warns that this reliance on nondurable methods without deep decarbonization risks undermining the credibility of corporate net-zero claims. The study examined 35 major companies across sectors including agrifood, aviation, automobiles, fashion, fossil fuels, tech, and utilities. Tech companies, led by Microsoft

Researchers in Taiwan have engineered a novel metabolic pathway, the malyl-CoA-glycerate (McG) cycle, to enhance carbon dioxide absorption and utilization in plants. By integrating this cycle alongside the traditional Calvin-Benson-Bassham cycle in the model plant Arabidopsis thaliana, they significantly increased plant growth, seed yield, and lipid production without raising water consumption. The McG cycle captures carbon more efficiently by incorporating carbon at two steps and produces a two-carbon molecule directly usable for lipid synthesis. This metabolic rewiring led to plants that were two to three times heavier, with more and larger leaves, and dramatically higher triglyceride levels, demonstrating improved biomass and potential for biofuel applications. Despite these promising results, the researchers caution that the findings are preliminary and based on a lab-friendly weed rather than crops or trees. The effects of excess lipid accumulation in larger plants and performance under field conditions remain uncertain. Additionally, the long-term carbon sequestration benefits depend on whether the lipids remain stable

A recent report reveals that the Trump administration has introduced nearly $40 billion in new federal subsidies for oil, gas, and coal in 2025 through the One Big Beautiful Bill Act, increasing annual fossil fuel subsidies by about $4 billion over the next decade. This addition raises the total federal support for domestic fossil fuels to at least $34.8 billion per year, marking the largest single-year increase in fossil fuel subsidies since at least 2017. These subsidies build on longstanding tax breaks, some dating back over a century, such as the 1913 deduction for drilling expenses, highlighting the entrenched nature of fossil fuel support in U.S. policy. Efforts to reduce fossil fuel subsidies have faced significant political obstacles. Although President Biden initially pledged to eliminate certain fossil fuel tax breaks to raise $35 billion over ten years, these plans were abandoned during climate legislation negotiations with Senator Joe Manchin, a key swing vote with ties to the coal industry. The resulting Inflation Reduction Act of 2022

The article from CleanTechnica discusses a significant reassessment of global carbon capture and storage (CCS) capacity, challenging the long-held assumption that geological storage is nearly limitless. Previous estimates suggested sedimentary basins could store between 10,000 and 40,000 gigatons of CO₂, with industry and policy often treating storage as an infinite backstop for ongoing fossil fuel use and climate overshoot scenarios. However, a new study published in Nature applies a comprehensive risk-based analysis incorporating factors such as seismic risk, depth constraints, proximity to urban areas, environmental protections, and geopolitical considerations. This approach reduces the realistic, prudent global storage capacity to about 1,460 gigatons—roughly 90% less than earlier technical estimates. This recalibration has profound implications for climate strategy. The limited storage capacity means CCS cannot simultaneously serve as a broad solution for continued fossil fuel emissions and a safety valve for overshoot mitigation. Most existing 2 °C climate pathways already exceed this prudent

Scientists at Harvard, led by assistant professor Richard Y. Liu, have developed a novel method to capture carbon dioxide (CO₂) from the air using sunlight. Their approach employs specially designed organic molecules called photobases that, when activated by sunlight, generate hydroxide ions capable of efficiently capturing and releasing CO₂. Unlike current direct air capture technologies, which require significant energy input, Liu’s light-driven process offers a low-energy, reversible, and potentially solar-powered alternative, representing a promising step toward scalable greenhouse gas removal solutions. Liu’s research integrates expertise from chemistry, materials science, and engineering, with collaboration from energy professor Daniel G. Nocera. Funded primarily by an NSF CAREER award and supported by Harvard amid federal funding challenges, the work exemplifies practical innovation combined with educational goals. The team’s findings, published in Nature Chemistry, highlight how creative molecular design can harness abundant sunlight to address climate change by enabling more energy-efficient carbon capture technologies.

The article presents a discussion among investors Laurent Segalen, Gerard Reid, and Michael Barnard on the "seven deadly sins" of the clean energy transition, using the traditional seven deadly sins as a metaphor to critique various energy technologies and investment approaches. They identify greed with carbon capture and direct air capture, criticizing these technologies as subsidy-driven and inefficient in reducing CO₂ emissions. Gluttony is linked to hydrogen, described as an energy carrier with excessive energy demands. Sloth corresponds to nuclear power and small modular reactors, implying slow progress or overreliance on these technologies. Pride is associated with fusion energy, seen as promising but currently irrelevant to near-term decarbonization. Lust refers to biofuels, which are tempting due to compatibility with existing engines but are only suitable for hard-to-electrify sectors. Wrath is connected to political opposition to offshore wind in the U.S., and envy critiques superficial ESG (Environmental, Social, and Governance) reporting, which is sometimes treated as a

The article discusses Houston-based Utility Global’s (UG) innovative approach to producing clean hydrogen without relying on the conventional color-coded classifications (green, blue, grey) typically used in the hydrogen industry. UG’s patented H2Gen system uniquely utilizes the inherent energy in industrial waste gases—such as off-gases from steel mills and methane-rich biogas from landfills and farms—to drive hydrogen production. This method bypasses the large electricity demands of traditional water electrolysis, effectively turning environmental liabilities into a free energy source. Additionally, the system captures a concentrated CO₂ stream, making carbon sequestration more feasible and cost-effective. A key challenge of UG’s technology lies in the precise control required for the electrochemical reactions within its solid oxide reactors, as minor fluctuations in temperature, pressure, or gas composition can affect efficiency and hydrogen purity. To address this, UG partners with Rockwell Automation, which provides an advanced control system (PlantPAx Distributed Control System) that continuously monitors and adjusts process variables in real

Researchers at the University of Sharjah in the UAE have developed an innovative method to convert shrimp waste—specifically shells, heads, and guts—into activated carbon capable of capturing carbon dioxide (CO₂). This process addresses two major environmental challenges simultaneously: managing the vast amounts of seafood waste generated globally (up to eight million tons annually) and mitigating climate change by reducing greenhouse gas emissions. The shrimp waste, sourced from Souq Al Jubail in Sharjah and originally from Oman, undergoes a multi-step treatment involving pyrolysis to create biochar, followed by acid treatment, chemical activation, and ball milling to produce a highly effective and stable CO₂ adsorbent. Beyond carbon capture, the activated carbon derived from shrimp waste has versatile applications including air and water purification, solvent recovery, gold extraction, and certain medical uses. The researchers emphasize that this approach exemplifies a circular economy by transforming problematic waste into a valuable resource, enhancing resource efficiency and sustainability.

A research team at the University of Houston, led by Professor Mim Rahimi, has developed two significant innovations aimed at making carbon capture more efficient and affordable. The first breakthrough replaces costly ion-exchange membranes in amine-based CO₂ capture systems with engineered gas diffusion electrodes, achieving over 90% carbon removal efficiency—nearly 50% higher than traditional electrochemically mediated amine regeneration (EMAR) methods. This membraneless system also reduces energy consumption and lowers capture costs to about $70 per metric ton, comparable to leading amine scrubbing technologies, potentially enabling easier retrofitting of existing industrial exhaust systems. The second innovation integrates carbon capture with renewable energy storage through a vanadium redox flow battery developed by Ph.D. student Mohsen Afshari. This system captures CO₂ during battery charging and releases it upon discharge, while maintaining cycle stability and strong capture capacity. By combining carbon removal with grid stabilization, this dual-function device could help power plants and heavy emitters reduce

Researchers at Pennsylvania State University have developed an improved method for enhancing oil recovery from shale rock formations using cyclic carbon dioxide (CO2) injection, also known as "CO2 huff-n-puff." This multi-phase process involves injecting CO2 into shale reservoirs, allowing it to soak and mix with trapped hydrocarbons in microscopic nanopores, thereby increasing oil mobility and extraction. Tested successfully in Texas’s Eagle Ford Shale, the technique demonstrated up to a 15% increase in shale oil recovery and shows potential for broader application across various shale reservoirs. The method not only boosts oil production but also offers a means for long-term CO2 storage, contributing to environmental benefits alongside energy gains. The effectiveness of the process depends on operational variables such as injection volume, reservoir depth, and oil type, with deeper reservoirs containing low gas–oil ratio black oil being particularly favorable. By optimizing CO2 injection parameters, the workflow aims to recover a significant portion of the oil—addressing the current inefficiency where up to

The article discusses the recent failure of a United Nations conference in Geneva aimed at finalizing a global treaty to address the full life cycle of plastics, including production, design, and disposal. Originally agreed upon by 175 nations in March 2022, the treaty sought to limit plastic production, improve cleanup and recycling, and reduce toxic chemicals associated with plastics. However, the conference ended without a deal, largely due to opposition from oil-producing "petrostates" such as Saudi Arabia, Russia, and Iran, who resisted any production caps or binding measures. These countries argued that limiting plastic production would harm commerce and civilization, echoing tactics seen in past climate negotiations. Many countries, including Colombia, the EU, the UK, and small island developing states (SIDS), expressed deep disappointment with the draft treaty, which lacked binding commitments, financial mechanisms, and provisions to phase out harmful chemicals. Representatives from Micronesia and other nations criticized the process as biased and favoring the interests of petro-states

The article highlights significant progress in the field of direct air carbon capture (DAC), focusing on the collaboration between Swiss firm Climeworks and Icelandic startup Carbfix at the Hellisheiði geothermal power plant. Since its founding in 2009, Climeworks has been developing DAC technology to economically remove atmospheric CO2. Partnering with Carbfix, which specializes in underground carbon mineralization, they have integrated DAC with Carbfix’s process of injecting CO2-rich, acidic carbonated water into basaltic rock formations. This results in rapid mineralization, permanently storing over 95% of injected CO2 as stable carbonates within two years—much faster than previously expected. The geothermal plant’s volcanic emissions, although low compared to fossil fuel plants, provide a target for this carbon removal, enhancing Iceland’s reputation for low-carbon energy. The collaboration has evolved since 2017, with Climeworks expanding its DAC facility at Hellisheiði and applying lessons from their initial “Arctic Fox” pilot.

A German startup, Humify, has revived a nearly century-old high-pressure process known as hydrothermal humification to rapidly regenerate soil and capture significant amounts of CO2. By heating organic waste to 200°C under pressure with water, they produce artificial humic substances—nutrient-rich polymers that mimic natural soil components. When added to soil, these substances enhance moisture and mineral retention, stimulate beneficial microbial ecosystems, and can bind up to 50 tons of carbon per hectare within the first year. This method compresses a natural soil regeneration process that typically takes over 3,000 years into just weeks, offering a promising solution to soil degradation and climate change. The process repurposes the Bergius-Pier method, originally developed in the early 20th century for converting biomass into fuel, to instead restore soil health and trap carbon underground. Humify’s approach is flexible, working with various organic wastes and adaptable to local agricultural conditions. Field trials in China have shown crop yield increases of up

Peter Minor, Co-Founder of Absolute Climate, first encountered the concept of carbon dioxide removal (CDR) in 2014 during his graduate studies at UC Berkeley, but his professional involvement began in 2019 at Carbon180. Absolute Climate distinguishes itself by developing independent quality-assurance standards that uniformly evaluate all carbon removal projects, enabling buyers to compare projects fairly. Crucially, the organization separates quality assurance from credit issuance to avoid conflicts of interest, ensuring that the entity defining credit quality is distinct from the one issuing credits. Minor reflects that if he were to restart Absolute Climate, he would focus earlier on local policy engagement, as impactful climate policies often originate at city or state levels, building momentum and grassroots support. Looking ahead, he acknowledges that while carbon removal is still proving its essential role in climate change mitigation, Absolute Climate aims to be pivotal in aligning incentives toward quality and providing robust evidence of real atmospheric benefits. He also highlights ongoing challenges, such as balancing resources between emissions reductions and negative emissions, noting

UK-based sustainable materials company earth4Earth (e4E) has developed innovative bricks made from excavated soil and a unique lime-based binder that capture and permanently store atmospheric carbon dioxide (CO₂). Unlike traditional lime binders, which require high-temperature processing that emits CO₂, e4E’s binder is produced at room temperature and stores all CO₂ generated during manufacturing as stable carbonates, eliminating emissions. These bricks use Direct Air Capture (DAC) technology to absorb CO₂ from the air, turning buildings constructed with them into carbon sinks while enhancing the bricks’ material properties. e4E offers a product line with varying binder content—N10, N20, and N30 bricks containing 10%, 20%, and 30% binder respectively—where higher binder percentages correspond to increased carbon absorption. The company has pilot projects underway in the UK and plans to begin local production next year, creating around 30 jobs. With a research center in Sheffield and a factory in Wuhan, China,

Daniel Liss, co-founder of the social network Dispo and the dating app Teaser AI, has shifted his focus from social media to steelmaking, driven by concerns about U.S. supply chain vulnerabilities highlighted during a National War College war game exercise. The exercise underscored the lack of domestic shipbuilding capacity and steel production critical for national defense, inspiring Liss to found Nemo Industries. Nemo aims to modernize the outdated steel industry by using AI to optimize pig iron production, moving beyond traditional, manual methods. Unlike typical industrial software firms, Nemo plans to build and operate its own furnaces, leveraging AI from the ground up to gain a significant margin advantage. Nemo’s approach includes using natural gas-fired furnaces, which emit less carbon dioxide than the coal commonly used in steelmaking, and exploring carbon capture technologies supported by tax incentives from the Inflation Reduction Act. Liss’s partner, Michael DuBose, brings expertise from the natural gas sector, which is critical for scaling operations.

Researchers at USC Viterbi School of Engineering have developed Allegro-FM, an AI-powered simulation tool capable of modeling the behavior of over 4 billion atoms simultaneously with 97.5% efficiency. This represents a nearly 1,000-fold increase in scale compared to traditional models. Using the Aurora supercomputer at Argonne National Laboratory, Allegro-FM enables scientists to virtually test molecular compositions of concrete, accelerating the discovery of carbon-neutral, stronger, and fire-resistant formulations without costly lab experiments. The AI system can simulate complex atomic interactions across 89 chemical elements, making it versatile for applications beyond concrete, including carbon storage, battery chemistry, and biomedical devices. The key breakthrough is Allegro-FM’s ability to predict atomic interactions without relying on element-specific quantum mechanical equations, instead using machine learning trained on extensive datasets. This allows for highly accurate and efficient simulations of concrete’s mechanical and structural properties. The researchers found that incorporating CO₂ into concrete can trap carbon dioxide released during cement production,

The U.S. Energy Information Administration’s Annual Energy Outlook 2025 (AEO2025) introduces a new Carbon Capture, Allocation, Transportation, and Sequestration (CCATS) module to model carbon capture deployment through the coming decades. The report projects that CO2 capture at electric power and industrial facilities will increase through the 2030s, primarily driven by enhanced tax credits established under the 2022 Inflation Reduction Act (IRA). These tax credits, which can be claimed for projects beginning construction before 2033 and last for up to 12 years after service, significantly incentivize carbon capture, with projected peak capture rates reaching between 1.5% and 3.5% of energy emissions in the late 2030s. However, CO2 capture is expected to decline after these credits expire by mid-century. The AEO2025 scenarios show variation in peak CO2 capture amounts, ranging from about 56 million metric tons (MMmt) in the Alternative Electricity case

President Trump’s $4 trillion “Big Beautiful” spending bill, signed on July 4, contains significant contradictions regarding energy and climate policy. Despite Trump’s skepticism about climate change, the bill increases federal subsidies for carbon capture projects, but only if the captured gas is used to enhance oil and gas extraction. The legislation cuts support for wind and solar energy—some of the cheapest energy sources—leading to an expected rise in average household energy costs by about $280 annually. It also phases out subsidies for electric vehicles, clean energy, and energy-efficient appliances, while providing substantial tax breaks and subsidies to the oil and gas industry. Key giveaways to fossil fuel companies include a reduction in royalty rates for drilling on public lands from 16.7% (set by the Inflation Reduction Act under Biden) to 12.5%, and the requirement for the Department of the Interior to conduct at least 30 offshore lease sales in the Gulf of Mexico, offering a minimum of 80 million acres each.

Microsoft has partnered with waste management firm Vaulted Deep in a 12-year agreement to offset 4.9 million metric tons of carbon emissions generated by its artificial intelligence operations. The company’s approach involves injecting a slurry of human and farm waste—including biosolids, manure, and food waste—5,000 feet underground into sealed rock formations. This method, which has been used for decades to manage industrial waste, effectively locks away carbon that would otherwise contribute to greenhouse gas emissions. For each ton of carbon sequestered this way, Microsoft earns carbon removal credits, helping it reduce its net emissions and advance its goal of becoming carbon negative by 2030. Vaulted Deep’s technique stands out because it leverages existing infrastructure rather than relying on slower or less scalable options like tree planting or direct air capture. The process also addresses environmental concerns associated with traditional waste disposal methods, such as nutrient runoff and methane emissions from land-applied biosolids. While the approach offers measurable climate and public health benefits

Japanese researchers from Yokohama National University, Electric Power Development Co., Ltd., and Japan’s National Institute of Advanced Industrial Science and Technology (AIST) have developed a novel method to convert carbon dioxide (CO2) from thermal power plant exhaust directly into valuable organic chemicals using recycled silicon wafers from discarded solar panels. By pretreating crushed solar panel silicon wafers with hydrochloric acid to remove aluminum contaminants, the team enhanced the wafers’ ability to act as reducing agents in the reaction. The process involves combining the untreated exhaust gas (containing about 14% CO2) with water, a catalyst (tetrabutylammonium fluoride), and the recycled silicon powder, resulting in the efficient production of formic acid and formamide without the need for CO2 purification. This breakthrough offers a dual environmental benefit: it repurposes waste silicon from obsolete solar panels—addressing the growing issue of photovoltaic panel disposal predicted to reach tens of millions of metric tons by 2050

Microsoft is accelerating its efforts to meet its 2030 carbon-negative pledge by purchasing large volumes of carbon removal credits, including a recent deal to acquire 4.9 million metric tons of carbon removal from Vaulted Deep, a startup specializing in underground carbon sequestration. Vaulted Deep collects solid waste materials such as treated sewage, manure, and paper sludge, converts them into a slurry, and injects this mixture into porous underground rock formations using fracking-derived technology. This 12-year agreement, running through 2028, represents a significant step in Microsoft's strategy to offset its growing emissions, which have increased by nearly 25% since 2020 due to rapid data center expansion. Despite heavy investments in renewable energy, Microsoft faces challenges in eliminating emissions from essential operations like semiconductor manufacturing, which currently lack zero-greenhouse-gas alternatives. In 2024, the company reported 14.9 million metric tons of greenhouse gas emissions, more than double its target for 2030. To bridge this

The article highlights an innovative approach to reducing pollution from maritime shipping, a sector responsible for about 3% of global carbon emissions. London-based company Seabound has developed a retrofit technology that captures carbon dioxide emissions from a ship’s existing internal combustion engines and converts the CO2 into limestone, a key ingredient in cement. This system is currently installed on the UBC Cork, a cement carrier sailing in the Mediterranean. The limestone produced during the voyage will be offloaded in Norway and used at Heidelberg Materials’ net-zero cement plant in Brevik, thereby closing a carbon loop between shipping and cement production—two industries that together contribute roughly 11% of global emissions. The technology offers a practical alternative to other decarbonization methods like batteries or ammonia fuel, which either lack sufficient energy density for long voyages or require extensive engine overhauls. Seabound’s retrofit allows ships to maintain their existing engines while capturing emissions directly from exhaust pipes. This innovation aligns with the International Maritime Organization’s (IMO

The article highlights the growing interest in marine carbon dioxide removal (mCDR) as a crucial strategy for addressing climate change and supporting biodiversity. Oceans naturally absorb about 30% of human CO₂ emissions and store significantly more carbon than the atmosphere, offering advantages over land-based carbon removal methods by avoiding competition with agriculture and urban areas. Various mCDR techniques, such as seaweed farming and electrochemical CO₂ removal, can operate offshore or near coastal infrastructure, providing scalable and less land-constrained solutions. Additionally, many mCDR approaches bring ecological benefits like reducing ocean acidification and enhancing marine habitats, though some methods carry risks such as trace metal introduction or harmful algal blooms, which ongoing research aims to mitigate. A key challenge for mCDR is robust measurement, reporting, and verification (MRV) due to the ocean’s complex dynamics, making carbon quantification more difficult than on land. However, progress is being made with new protocols and standards developed by organizations like Isometric, Carbon

Chinese scientists have developed an innovative enzyme-based method to convert methanol into sucrose (white sugar) without relying on traditional agriculture. This biotransformation system uses in vitro biotransformation (ivBT) to synthesize complex carbohydrates from methanol, which can be derived from industrial waste or chemically converted carbon dioxide. This breakthrough offers a sustainable alternative to sugar production that bypasses the need for land- and water-intensive crops like sugar cane and sugar beets, addressing environmental challenges and food security concerns amid climate change and population growth. The research, led by the Tianjin Institute of Industrial Biotechnology under the Chinese Academy of Sciences, achieved an 86% conversion rate of methanol into sugars, including sucrose and starch, using fast, low-energy enzymatic reactions. This method builds on earlier advances in converting CO₂ into methanol, effectively turning carbon waste into valuable food ingredients. Beyond sucrose, the system can produce a variety of carbohydrates such as fructose, amylose, and cellooligos

Researchers at the University of Pennsylvania have developed an innovative algae-based concrete that significantly reduces environmental impact while maintaining structural integrity. By incorporating diatomaceous earth—powder made from fossilized silica shells of microscopic algae—into a 3D-printed concrete mix, the team created a lightweight material that uses 68% less cement and absorbs 142% more CO₂ compared to traditional concrete. This breakthrough leverages the natural carbon-trapping abilities of diatoms and a mathematically optimized internal geometry inspired by coral reefs and sea stars, known as triply periodic minimal surfaces (TPMS), which maximize surface area and stiffness with minimal material. The new concrete not only captures more carbon dioxide but also grows stronger over time during curing, retaining 90% of the strength of conventional solid concrete blocks despite its high porosity. The design incorporates post-tensioning cables and advanced force-balancing geometries to ensure durability and buildability at architectural scales. The researchers are currently scaling up the technology for larger applications such

Arbor, supported by a $41 million deal with Frontier, is developing its first commercial-scale power plant in southern Louisiana that uses waste biomass to generate electricity for data centers while capturing and sequestering the resulting CO2 underground. This technology, called BiCRS (biomass carbon removal and storage), produces carbon-free base load energy and achieves net carbon removals by burning biomass and capturing 99% of the CO2 emissions. The process involves converting biomass into syngas using a proprietary gasifier that employs supercritical CO2, then combusting the syngas with pure oxygen to generate electricity via turbomachinery, while diverting most CO2 for permanent storage. The approach leverages sustainable biomass sources, with Frontier emphasizing careful vetting to ensure biomass use does not disrupt natural cycles or soil health. Although biomass availability varies, estimates suggest 1 to 5 gigatons of waste biomass could be sustainably utilized annually, offering significant potential for BiCRS and related bioenergy with

In the early 2000s, engineers at the Techint Group accidentally discovered a methane pyrolysis reaction while working on an electric arc furnace at a steel plant. Instead of the expected breakdown of carbon electrodes, the furnace split methane into hydrogen gas and solid carbon without releasing carbon dioxide. This discovery was initially overlooked but recently revived by Techint’s venture arm, leading to the creation of Tulum Energy, a startup aiming to commercialize this cleaner hydrogen production method. Tulum has raised $27 million in seed funding and is building a pilot plant in Mexico adjacent to a Techint steel mill, with plans to supply both hydrogen and solid carbon for industrial use. Methane pyrolysis offers a low-emission alternative to the conventional steam methane reforming process, which emits significant CO₂. Unlike competitors, Tulum’s approach does not require costly catalysts, relying instead on a modified electric arc furnace, potentially reducing complexity and costs. The company projects hydrogen production costs around $1.50 per kilogram—competitive
energyhydrogen-productionmethane-pyrolysisclean-energysteel-industryelectric-arc-furnacecarbon-captureNew method pulls CO2 from air using cold air, simple sorbents
Researchers at Georgia Tech have developed a novel, cost-effective method for capturing atmospheric CO₂ by leveraging extremely cold air and simple, widely available porous sorbent materials called physisorbents. Their technique utilizes the cold energy generated during liquefied natural gas (LNG) regasification—a process that typically wastes this cold—to chill ambient air to near-cryogenic temperatures (~ -78°C). This cooling removes water vapor naturally, creating ideal conditions for physisorbents like Zeolite 13X and CALF-20 to efficiently absorb CO₂ without the energy-intensive drying steps required by traditional direct air capture (DAC) systems that rely on chemical amines. The physisorbents demonstrated roughly three times higher CO₂ capture capacity at these low temperatures compared to room temperature, while also requiring less energy for CO₂ release and offering greater durability. Economic modeling indicates this approach could reduce DAC costs to around $70 per metric ton of CO₂—less than one-third of current expenses—potential

The article discusses the significant carbon dioxide and pollutant emissions produced by ocean-going ships, which exceed those from air travel. Traditional marine engines burn bunker oil, a thick, cheap residual fuel that also serves as the engine’s lubricant, making it difficult and costly to switch to cleaner fuels or retrofit ships with modern engines. Such retrofits are expensive—costing upwards of half a million dollars—and require ships to be out of service for extended periods, creating financial disincentives for shipowners to adopt cleaner technologies. A promising solution comes from a London-based company called Seabound, which has developed an onboard carbon capture system ready for immediate deployment. The system uses steel containers filled with quicklime pellets that chemically react with the ship’s exhaust CO2, converting it into limestone and thereby reducing emissions. Quicklime is a widely produced industrial material, making this approach scalable and practical. The technology was conceived by entrepreneur Alisha Fredriksson, inspired by climate change reports, who adapted existing industrial carbon capture

The article analyzes the economic viability of emerging low-carbon steelmaking technologies in light of slowed steel demand growth and heightened scrutiny on cost, carbon intensity, and feasibility. It highlights five key steelmaking routes, including hydrogen-based direct reduced iron (DRI) with carbon capture and storage (CCS), natural gas with CCS, and molten oxide electrolysis (MOE). The author emphasizes that realistic assumptions about electricity costs, fuel prices, and carbon policies are crucial for assessing these technologies’ prospects, using examples from Northeastern Europe and Australia to illustrate regional cost variations. A central conclusion is that hydrogen-based steelmaking is unlikely to achieve cost parity due to persistently high green hydrogen prices, which remain between $5 to $8 per kilogram in most developed countries and $3 to $4 in renewable-rich regions. This high cost stems from the inefficiencies and electricity intensity of electrolytic hydrogen production, storage, and compression. Earlier optimistic assumptions about rapidly falling hydrogen costs and free or nearly free renewable electricity have proven

Caltech researchers have developed an innovative system that converts carbon dioxide (CO₂) from the air into durable, industrial-grade plastics using only electricity and chemistry. This breakthrough mimics natural photosynthesis but employs machines instead of plants, utilizing renewable electricity to first transform CO₂ into simple building blocks such as ethylene and carbon monoxide. These compounds are then fed into a second catalytic loop where they are converted into polyketones—high-strength plastics valued for their durability and thermal stability, commonly used in adhesives, automotive parts, sports equipment, and industrial piping. Unlike previous methods relying on fossil-derived ethylene, this process uses sustainably sourced CO₂, water, and electricity, potentially reducing emissions and dependence on petroleum-based feedstocks. The system operates via two separate loops optimized for different reaction conditions. The first loop uses gas diffusion electrode cells with copper-coated hydrophobic polymers to electrochemically reduce CO₂ into ethylene and carbon monoxide at relatively high concentrations (11% and 14%, respectively). These gases

Researchers at ETH Zurich have developed an innovative, sustainable building material infused with live cyanobacteria that actively captures atmospheric carbon dioxide through photosynthesis and biocementation. This 3D-printed hydrogel-based material houses photosynthetic bacteria within a polymer network designed to optimize light, CO2, water, and nutrient flow, enabling the bacteria to remain productive for over a year. The material sequesters CO2 both biologically and by forming stable mineral carbonates, which strengthen the initially soft gel into a robust, hardened structure over time. Laboratory tests demonstrated that the material can bind approximately 26 milligrams of CO2 per gram, outperforming typical biological methods and rivaling chemical mineralization in recycled concrete. The technology has moved beyond the lab, with large-scale installations such as the "Picoplanktonics" exhibit at the Architecture Biennale in Venice, featuring three-meter-high structures capable of capturing up to 18 kilograms of CO2 annually—comparable to a mature pine tree.

Researchers at Brookhaven National Laboratory have developed a novel catalyst inspired by photosynthesis that converts carbon dioxide (CO2) into formate, a valuable industrial chemical, using only light, protons, and electrons. This ruthenium-based catalyst mimics the natural process of photosynthesis by storing solar energy in chemical bonds through proton and electron transfers triggered by light. The innovation addresses the urgent need to reduce atmospheric CO2 by not only capturing it but also transforming it into useful compounds for fuels, pharmaceuticals, and antimicrobial products. The team redesigned the catalyst’s structure by surrounding the metal center with ligand “petals,” shifting the chemical activity from the metal to the ligands. This approach prevents CO2 from binding directly to the metal, which traditionally leads to side reactions and catalyst degradation. As a result, the process selectively produces formate without generating competing byproducts like hydrogen or carbon monoxide. Additionally, this ligand-based mechanism allows for flexibility in the choice of the central metal; while ruthenium was used

The article discusses the evolving landscape of carbon capture technologies, with a particular focus on direct air capture (DAC) and mineralization as promising approaches for long-term carbon sequestration. While federal support for carbon capture in the US is declining—highlighted by the Department of Energy’s recent cancellation of a $3.7 billion decarbonization demonstration program—global efforts continue to advance. The article contrasts various carbon capture methods, noting that biofuels and electrofuels recirculate carbon but depend heavily on supportive public policies. More durable sequestration options include reforestation and reforming captured carbon into solid products, such as incorporating it into cement. Mineralization emerges as a key solution for sustainable, long-term carbon storage by chemically locking carbon dioxide into stable carbonate minerals through reactions with reactive igneous or metamorphic rocks. This method offers advantages over traditional underground sequestration in porous sedimentary rock, where carbon can potentially escape. The US Geological Survey estimates significant underground sequestration capacity, but

The article critically examines the viability of geological carbon dioxide (CO₂) sequestration as a large-scale climate mitigation strategy. While geological storage has gained traction, partly due to less aggressive electrification scenarios and fossil fuel industry influence, real-world experience from enhanced oil recovery (EOR) operations raises serious concerns about its effectiveness. EOR wells, which inject tens of millions of tonnes of CO₂ annually, already exhibit non-negligible leakage rates and mechanical integrity failures. These wells operate under less demanding conditions than dedicated sequestration wells, which must contain supercritical CO₂ under high pressure and corrosive environments for centuries or millennia. The higher risks of leakage and containment failure in future sequestration projects pose a significant challenge to meeting climate goals that require near-zero leakage over very long timescales. Scaling geological sequestration to the levels projected by organizations like the International Energy Agency—around 7.6 gigatonnes of CO₂ per year by mid-century—would require an unprecedented expansion of current capacity

The article discusses the recent announcement by the U.S. Environmental Protection Agency (EPA) to repeal all greenhouse gas (GHG) emissions standards for fossil fuel-fired power plants, effectively eliminating regulations established under previous administrations, notably those of Barack Obama and Joe Biden. The EPA’s justification centers on the claim that carbon dioxide emissions from thermal power plants have decreased from about 5.5% of global emissions in 2005 to approximately 3% today, arguing that further reductions would have minimal impact on public health. The proposal includes repealing emission guidelines for existing fossil fuel steam units and carbon capture and sequestration (CCS) standards for coal-fired plants and new turbines, signaling a significant rollback of environmental protections. Supporters of the rollback, including EPA Administrator Lee Zeldin, former President Donald Trump, and industry representatives like the National Mining Association and West Virginia Governor Patrick Morrisey, praise the move as a boost to coal power, energy dominance, and economic development. They emphasize the importance of

Researchers at Rice University have developed a simple yet effective modification to electrochemical carbon capture systems that dramatically extends their operational lifespan. By replacing the conventional water-based humidification of CO2 gas with mild acid vapors—such as hydrochloric, formic, or acetic acid—the team prevented the formation of potassium bicarbonate salt deposits that typically clog gas flow channels and flood electrodes. This acid vapor approach dissolves the problematic salts, allowing them to be carried away with the gas flow, thereby avoiding blockages that cause premature device failure. Testing showed that this acid-based humidification enabled stable operation for over 4,500 hours in a 100-square-centimeter electrolyzer—more than 50 times longer than the roughly 80 hours achievable with traditional water humidification. The method proved effective across various catalysts including silver, zinc oxide, copper oxide, and bismuth oxide, without causing significant membrane corrosion due to the low acid concentrations used. Because the modification requires only minor changes to existing humidification setups

The US Environmental Protection Agency (EPA) has proposed rolling back emissions standards for power plants, which are the second-largest source of CO2 emissions in the country. This move comes shortly after NOAA reported record-high seasonal CO2 concentrations. EPA Administrator Lee Zeldin criticized previous administrations for prioritizing environmental regulations over economic growth, emphasizing the agency’s intention to support domestic fossil fuel industries, including coal, which has been in decline due to competition from natural gas and renewables. The proposed rollbacks would weaken Biden-era rules that required coal- and gas-fired power plants to reduce emissions by 90% by the early 2030s, primarily through carbon capture and storage technology. The EPA’s justification for the rollbacks includes the argument that US power sector emissions represent a small fraction (3%) of global emissions, and that continued coal use abroad diminishes the impact of US regulations on global greenhouse gas levels. However, critics highlight that the US power sector remains a major domestic polluter, ranking second only
energyEPApower-plantsemissionscarbon-capturefossil-fuelsclimate-policyNew method turns carbon emissions into solid cement ingredients
Researchers at the University of Michigan, led by chemist Charles McCrory, have developed a novel method to capture carbon dioxide (CO₂) from the air and convert it into metal oxalates, stable solid compounds that can serve as precursors for cement production. This approach aims to transform CO₂, typically viewed as a waste product, into valuable building materials, potentially reducing the carbon footprint of construction. The work is part of efforts by the Center for Closing the Carbon Cycle (4C), funded by the U.S. Department of Energy, which focuses on converting captured carbon into useful fuels and industrial products. The team’s innovation centers on using trace amounts of lead as a catalyst to convert CO₂ into metal oxalates via electrochemical reactions. By employing specially designed polymers, they reduced the lead catalyst to parts per billion—levels comparable to natural impurities—addressing previous environmental and health concerns associated with higher lead usage. In the process, CO₂ is electrochemically transformed into oxalate ions, which then combine with metal ions released from an electrode to form solid metal oxalates. These solids are stable and do not revert to CO₂ under normal conditions, making them promising for cleaner cement production. While electrolysis of CO₂ is already being scaled up industrially, the researchers note that further work is needed to scale the metal oxalate production step, but they remain optimistic about its feasibility. This breakthrough offers a potential pathway to reduce the environmental impact of traditional Portland cement manufacturing, which is energy-intensive and a major source of global carbon emissions. By turning pollution into building blocks, the research opens new avenues for sustainable construction materials and carbon capture utilization. The study detailing these findings was published in the journal Advanced Energy.
