Why 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.

Maxion Wheels South Africa has commissioned a 2.9 MWp solar power plant at its Johannesburg manufacturing facility to supply about 20% of its annual electricity needs. Installed in a combination of carport and ground-mounted configurations, the solar installation aims to reduce reliance on the national grid, protect against rising electricity tariffs, and cut greenhouse gas emissions by approximately 5,100 tonnes annually. This project was launched during Maxion’s 60th anniversary and is part of a broader strategy to improve operational efficiency amid increasing energy costs and decarbonization pressures facing the automotive sector in South Africa. A second phase with additional rooftop solar capacity and potential battery storage is planned for completion by early 2026. The move reflects broader trends in the South African commercial and industrial solar market, where rapidly declining solar panel costs—from over 60 cents per watt in 2015 to under 12 cents per watt today—have made solar power a cost-effective alternative to grid electricity and diesel generators. This cost reduction

The article from CleanTechnica discusses California's significant transition from fossil diesel to renewable diesel and biodiesel, highlighting the impact on the state's refining industry and future fuel landscape. While diesel consumption in California had appeared stable despite declining gasoline demand, a closer look reveals that over 70% of diesel consumed now comes from renewable sources—renewable diesel and biodiesel—resulting in a faster-than-expected decline in fossil diesel use. Renewable diesel, produced through hydroprocessing, is a drop-in fuel compatible with existing engines and infrastructure and can reduce greenhouse gas emissions by about 65% compared to petroleum diesel. Biodiesel, chemically different and typically blended with petroleum diesel, offers variable emissions reductions depending on feedstock and blend ratios. This shift has created a structural imbalance for refineries, which are designed to produce fixed ratios of gasoline to diesel from crude oil, especially heavy crude. With California's fossil diesel demand shrinking, refineries face a surplus of petroleum diesel they cannot sell locally, leading them to export

Philippine telecommunications company Globe is transitioning over 3,000 of its cell sites and low-energy facilities in Metro Manila and the CALABARZON region to 100% renewable energy by 2028. This initiative, enabled by the Philippine Energy Regulatory Commission’s Retail Aggregation Program (RAP), allows Globe to bundle the power demands of multiple small sites to procure clean electricity from a single retail supplier. The move is expected to source 80 million kilowatt-hours of renewable electricity annually and reduce Globe’s greenhouse gas emissions by approximately 5,500 metric tons of CO₂ equivalent each year. This transition supports Globe’s commitments under the Science-Based Targets initiative (SBTi), aiming for a 42% reduction in absolute Scope 1 and 2 GHG emissions by 2030 and a 90% reduction across all scopes by 2050, using 2021 as the baseline. The collaboration with energy supplier ACEN RES, part of the Ayala Group, reinforces a

A recent University of California, Riverside study demonstrates that sealed dairy digesters can reduce methane emissions from manure by approximately 80% on a California dairy farm. Methane, a greenhouse gas over 80 times more potent than carbon dioxide over 20 years, is a significant contributor to global warming, with California dairy farms being major sources due to manure management. The study involved detailed atmospheric methane measurements before and after installing a digester at a Tulare County family-run dairy, revealing substantial emission reductions after addressing initial system leaks through collaboration between scientists, the system operator, and the farmer. Dairy digesters work by covering manure pits with gas-tight membranes that trap methane produced during anaerobic decomposition. The captured methane is then cleaned and repurposed as fuel, often powering trucks that would otherwise use diesel. While highly effective, digesters have limitations: they can leak if not properly maintained, do not reduce other pollutants like ammonia or fine particles, and require significant investment and regulatory permits, making them less feasible

At the 2025 UN Ocean Conference in Nice, environmental groups Opportunity Green, Seas At Risk, and Transport & Environment urged countries to include international shipping emissions in their Nationally Determined Contributions (NDCs) under the Paris Agreement ahead of COP30. They highlighted that shipping emissions represent a significant “glaring gap” in most countries’ climate plans despite falling under the Paris Agreement’s economy-wide emission coverage. The recent draft International Maritime Organization (IMO) Net-Zero Framework, pending adoption, marks a historic step by introducing the first legally binding global measure to reduce shipping greenhouse gas emissions through penalties and marine fuel standards. However, the groups emphasize that this IMO framework alone is insufficient to meet climate and equity goals without complementary national and regional policies. Incorporating shipping emissions into NDCs would provide countries with a legislative mandate to regulate and reduce the sector’s climate impact, offering certainty for industry investment in zero-emission technologies. The groups call on nations to implement policies supporting the IMO framework, promote innovation in zero-emission fuels, and assist developing countries, especially Small Island Developing States and Least Developed Countries, in meeting maritime environmental standards. Representatives stressed the urgent need for accountability and action, noting that shipping contributes significantly to ocean pollution and climate change but remains largely unregulated in national climate commitments. They argue that recognizing shipping emissions in NDCs aligns with broader ocean conservation goals and is a critical step toward meaningful climate action.
