Vema predicts cheap hydrogen could change where data centers are built
Vema, a startup specializing in producing hydrogen deep underground from iron-rich rocks, is pioneering a new method called stimulated geologic hydrogen or "engineered mineral hydrogen." By drilling wells into specific rock formations and treating them with water, heat, pressure, and catalysts, Vema extracts hydrogen gas for industrial use. The company recently completed a pilot project in Quebec and has secured a deal to supply hydrogen to California data centers. Vema’s CEO, Pierre Levin, highlighted that supplying the Quebec market would require only a small land footprint, and the first commercial well, planned for next year, will reach 800 meters deep. The company aims to produce hydrogen at less than $1 per kilogram, potentially dropping below 50 cents per kilogram with further refinement, making it cheaper and cleaner than most current hydrogen production methods. This innovation could significantly impact the location and energy sourcing of data centers, especially in regions like California, which have abundant iron-rich ophiolite rock formations. These formations could enable local, dec

The article from CleanTechnica critically examines Germany’s hydrogen backbone project, emphasizing that its challenges stem not from technical issues alone but from a decade of overly optimistic intellectual assumptions embedded in studies and models. These analyses consistently underestimated the complexities and costs associated with producing, storing, distributing, and using hydrogen as a general energy carrier. Unlike hydrogen’s established industrial uses, extending it broadly into energy systems involved stacking optimistic assumptions—such as low electrolyzer costs, cheap electricity inputs, and minimal infrastructure expenses—that ignored significant energy losses and capital requirements at each stage. This led to distorted projections that portrayed large-scale hydrogen use as both feasible and necessary, despite the harsh realities of energy conversion inefficiencies and infrastructure demands. The article highlights how this optimistic consensus became entrenched within Germany’s energy policy ecosystem through a process described as gruppendenken, where research institutions, industry, and policymakers circulated similar premises without sufficient critical review. As a result, hydrogen’s role in the energy transition was treated as inevitable rather than a hypothesis to

The article from CleanTechnica argues that the 2022 European energy crisis was not primarily caused by general import dependence or shortages of industrial feedstocks, but by reliance on an imported energy carrier—natural gas—that occupied a marginal role in electricity and heat markets. Because gas set marginal prices, its price spikes cascaded through electricity markets, household heating, industrial energy costs, and ultimately the broader economy, triggering inflation and fiscal interventions. Unlike feedstocks such as iron or ammonia, energy carriers like gas affect nearly all economic activities simultaneously, making their price volatility macroeconomically significant. The crisis demonstrated that even when gas supplied only a minority share of electricity generation, its marginal pricing role caused widespread price shocks. Governments had to intervene with price caps and subsidies to prevent social and industrial collapse. This context is critical when evaluating hydrogen as a future energy source. If hydrogen is used as a marginal fuel for power or industrial heat, its price will similarly influence overall electricity prices, regardless of volume consumed. Although green hydrogen

The article by Dhruv Soni highlights the critical challenge of scaling up clean energy process technologies in the United States amid the urgent need to address climate change. While the U.S. leads in early-stage innovation across sectors like carbon capture, hydrogen, sustainable fuels, and battery materials, it currently lags in scaling these technologies to commercial levels—a role increasingly filled by countries like China. The traditional model of innovation ("zero-to-one") followed by external scale-up ("one-to-one-hundred") is no longer sufficient given intensifying environmental crises, geopolitical shifts, and the pressing timeline to meet 2030 and 2050 emissions targets. Scientific innovation is no longer the bottleneck; rather, the key challenge lies in deploying technologies at scale and rebuilding domestic industrial capacity. Scale-up in chemical engineering involves increasing process throughput from lab or pilot scales to commercial scales, a transition fraught with technical, financial, and operational complexities. Physical and chemical behaviors do not scale linearly, and first-of-a-kind

The article critically examines hydrogen company Lhyfe’s recent claims of doubling revenue in 2025 and its strategic refocus for 2026, arguing that these announcements mask deeper financial and strategic problems. While Lhyfe’s revenue reportedly grew from €5 million to €10 million, this increase is from a very small base and does not indicate business viability. The company continues to incur substantial net losses—€21.7 million in 2025, albeit an improvement from previous years’ losses of €29.1 million and €33.5 million. Cost-cutting measures, including a 30% reduction in engineering, procurement, and construction (EPC) staff, are seen as insufficient to reverse the company’s cash burn and may undermine operational capabilities rather than drive sustainable profitability. The article uses Richard Rumelt’s framework for good strategy to critique Lhyfe’s approach, highlighting a flawed diagnosis of the company’s challenges. Lhyfe attributes its struggles mainly to external regulatory and policy hurdles

The article from CleanTechnica examines the challenges and economic viability of using hydrogen as an energy source in pulp and paper mills, focusing on a proposed project at the Kruger pulp mill in Kamloops, British Columbia. Pulp mills are significant fossil gas consumers, especially in lime kilns and recovery boilers, and are under pressure to decarbonize while maintaining economic stability in their communities. Hydrogen developers see these mills as potential markets, but past attempts, such as a project in Prince George that aimed to use by-product hydrogen from a chemical plant, failed when the chemical plant and mill closed, highlighting the fragility of hydrogen projects dependent on narrow industrial supply chains. The Kamloops project involves a 10 MW electrolyzer intended to produce about 4 tons of hydrogen and 32 tons of oxygen daily, aiming to reduce the mill’s fossil gas use by approximately 16% by substituting hydrogen in the lime kiln. Despite its promise as a decarbonization step, the project faces significant economic

The article "Hydrogen’s Seven Missing Pieces" from CleanTechnica critically examines the challenges facing hydrogen as a broad energy carrier beyond its established industrial uses. While hydrogen remains essential for sectors like fertilizer, petrochemicals, and biofuels—where low-carbon hydrogen is necessary to meet climate goals—the article argues that hydrogen is unlikely to scale effectively for heating, transport, and power due to a series of systemic barriers. The core issue is that hydrogen starts at a fundamental cost disadvantage compared to oil, gas, or electricity when measured per unit of energy (BTU), and the entire energy system must overcome this gap simultaneously for hydrogen to succeed widely. The article outlines seven critical conditions that must all be met for hydrogen to become a common energy carrier, emphasizing that failure in any one condition breaks the chain. Key points include the need for electrolyzers to achieve rapid cost reductions similar to solar panels and batteries, which currently is not happening due to slow production scaling and limited learning rates. Additionally, electrolyzer

The article critiques Australian billionaire Andrew "Twiggy" Forrest's dismissal of the climate risks posed by hydrogen as an energy source, highlighting a broader trend of "hydrogen climate harm denial." During a discussion with UK climate policy expert Baroness Bryony Worthington, Forrest challenged the established science that hydrogen acts as an indirect greenhouse gas by inhibiting the breakdown of methane, a potent greenhouse gas. Forrest accused the Environmental Defense Fund of spreading misinformation, but the article clarifies that his claims contradict well-established atmospheric science. Scientific consensus shows that hydrogen competes with methane for hydroxyl radicals in the atmosphere, reducing methane’s breakdown and thereby prolonging its greenhouse effect. Studies since the 1990s have quantified hydrogen’s global warming potential (GWP), with recent research indicating a GWP over 20 years approximately 33-37 times that of carbon dioxide and over 100 years about 11-12 times. While exact values vary, the evidence consistently indicates hydrogen’s significant indirect warming impact, especially relevant

Fortescue’s recent cancellation of two flagship green hydrogen projects—one in Gladstone, Australia, and another in Arizona, USA—signals significant economic challenges facing hydrogen as a mainstream energy source beyond industrial feedstock use. Despite substantial financial backing, government grants, and initial optimism, both projects proved financially unviable amid shifting policy landscapes and market realities. The Arizona project, an 80 MW facility, was undermined by the removal of US hydrogen subsidies, leading to a $150 million pre-tax loss write-off. Similarly, the Gladstone plant, partially operational and supported by about A$60 million in government grants, was shut down due to high costs and competitiveness issues, with potential grant repayments under evaluation. These setbacks underscore hydrogen’s struggle to compete economically without extensive subsidies, a pattern echoed globally as major firms like BP, Shell, and Iberdrola scale back or abandon hydrogen energy projects. The broader hydrogen industry faces mounting practical and financial hurdles, including infrastructure challenges related to storage, distribution,

Researchers from China have developed an advanced precursor seed layer engineering (PSLE) technique to significantly improve the performance of copper zinc tin sulfide (CZTS) photocathodes for solar-to-hydrogen (STH) conversion. CZTS, composed of earth-abundant elements, has been limited by defects and inefficient charge carrier dynamics, capping its efficiency below 8%. The PSLE method enhances crystal growth, reduces defect density to 9.88 × 10^15 cm^-3, and increases minority-carrier lifetime to 4.40 ns, resulting in a record half-cell solar-to-hydrogen efficiency of 9.91%. This approach also enabled the first unbiased CZTS-BiVO4 tandem cell to achieve 2.20% STH efficiency in natural seawater. The optimized CZTS films exhibit large, compact, uniform, and vertically aligned grains, which improve the CZTS/CdS heterojunction by increasing built-in voltage and lowering interfacial defects
