GEL’s Technical-Grade Lithium Milestone Could Reshape UK Critical Minerals Supply Geothermal Engineering Ltd’s latest announcement is an important step for the UK’s lithium ambitions. The company says lithium carbonate produced from deep geothermal brine at United Downs now meets the 99.3% purity threshold for technical-grade material, which means it can be sold directly to battery supply chains without further refining.   Why this milestone matters This is significant because it moves geothermal lithium closer to commercial relevance, not just technical proof. A material that already meets market specification is much easier to integrate into downstream battery and industrial supply chains. It also strengthens the case that geothermal brines can support both clean power generation and critical minerals production from the same asset base.   For the UK, the timing is especially relevant. The government has set a target of meeting 10% of domestic critical mineral dema...

Mazama Energy’s Athena drilling milestone points to a new phase for superhot rock geothermal Mazama Energy says its Athena well at Newberry, Oregon reached 10,350 feet in 15 drilling days, cutting the drilling time to the same depth by 80% versus its 2025 result. The company says the performance supports a broader case for superhot rock geothermal as a lower-cost, scalable source of firm power.   A faster drilling result Mazama’s update is important because drilling speed is one of the biggest cost drivers in geothermal development. Reaching the same depth in 15 days instead of the much longer 2025 campaign suggests the team is learning quickly and improving operational efficiency. The company also reported instantaneous rates of penetration above 350 feet per hour and sustained rates above 130 feet per hour over extended intervals.   That matters because geothermal economics often hinge on whether drilling can be made predictable, repeatable, and cheaper over time. ...

Fervo and Google sign world’s largest deal for next-gen geothermal power Fervo Energy’s latest agreement with Google is a major milestone for next-generation geothermal and a clear sign that big tech is getting more serious about 24/7 clean power. The deal covers 396 MW from Fervo’s Cape Station project in Utah, with the option for Google to expand its commitment later, potentially pushing the relationship much closer to gigawatt scale.   For the geothermal sector, the significance goes beyond one contract. It is a public validation that enhanced geothermal systems can attract a blue-chip corporate buyer at a size usually associated with utility-scale solar, wind, gas, or nuclear procurement. For Google, it strengthens a strategy centered on securing always-available, carbon-free electricity for future data center growth.   Fervo’s announcement also lands at a moment when electricity demand is rising fast, especially from artificial intelligence infrastructure. That ...

Strataphy Partners With HUMAIN to Deploy PrimeLoop Cooling Across Saudi Arabia’s AI Data Centers Saudi Arabia is moving rapidly to establish itself as a global artificial intelligence and data-center powerhouse, and one of the most important challenges facing that ambition is not simply how much computing capacity can be installed, but how efficiently that computing capacity can be cooled. At LEAP 2026, Strataphy announced a partnership with HUMAIN to deploy its PrimeLoop® cooling technology across HUMAIN’s data-center infrastructure in the Kingdom of Saudi Arabia. According to the announcement, the engagement represents the first deployment of its kind for PrimeLoop® in Saudi Arabia and is designed to address one of the fundamental constraints of large-scale AI infrastructure: thermal management. The partnership comes as HUMAIN works toward a target of approximately 6 GW of AI compute. At that scale, cooling becomes a strategic infrastructure issue rather than a conventional dat...

COWI and Sinotech Team Up on Taiwan’s Super-Hot Geothermal Potential Taiwan’s geothermal story is moving from possibility to execution, and the COWI-Sinotech collaboration is a sign that the sector is entering a more serious phase of development. The partnership is focused on unlocking super-hot geothermal resources, which could improve project economics and expand the country’s clean-energy options. Introduction Geothermal has long been one of Taiwan’s most intriguing renewable resources because the island sits on active tectonic terrain with strong heat potential. What has held the sector back is not a lack of heat, but the difficulty of converting that heat into bankable projects at scale. The new collaboration between COWI and Sinotech points to a more technical, internationally connected approach to solving that problem. Why Taiwan Matters Taiwan has ambitious decarbonization goals, and geothermal fits neatly into the need for firm, low-carbon power. Unlike solar and wind, geot...
