Idemitsu Invests in Quaise Energy: How Millimeter-Wave Drilling Could Unlock the World’s Deepest, Cleanest Power

Idemitsu Invests in Quaise Energy : Unlocking Superhot Geothermal Power with Revolutionary Millimeter-Wave Drilling By: Robert Buluma   In a significant move for the future of clean energy, Japanese energy giant Idemitsu Kosan Co., Ltd. has announced a strategic investment in Quaise Energy , a U.S.-based company pioneering next-generation geothermal technology. The investment, made through Idemitsu’s wholly owned subsidiary  Idemitsu Americas Holdings Corporation (IAH) on June 25, 2026, involves the issuance of convertible preferred shares. This partnership aims to accelerate the development of ultra-deep, superhot geothermal systems capable of delivering stable, high-output renewable power—a crucial step as the world accelerates its transition away from fossil fuels. Why Geothermal Matters More Than Ever Geothermal energy stands apart from other renewables because it provides baseload power—consistent, reliable electricity generation unaffected by weather conditions, unli...

TerraLithium and BHE Renewables Achieve Key Milestones Toward Commercializing Direct Lithium Extraction

TerraLithium and BHE Renewables Achieve Key Milestones Toward Commercializing Direct Lithium Extraction June 23, 2026 By:  Robert Buluma Introduction: A Turning Point for Domestic Lithium Production On June 22, 2026, TerraLithium—a wholly owned subsidiary of Occidental—and BHE Renewables announced significant advancements in their direct lithium extraction (DLE) technology portfolio, marking a pivotal moment for the domestic lithium supply chain in the United States. The companies have successfully produced lithium chloride using their DLE process at BHE Renewables' geothermal facility in Calipatria, California, followed by the manufacture of battery-grade lithium carbonate. Additionally, they achieved the direct conversion of lithium chloride into lithium hydroxide using a commercial-scale electrolyzer at TerraLithium's R&D facility in Brawley, California. These milestones represent more than just technical achievements—they signal the emergence of a responsible, domestic ...

The Future of Geothermal Energy: Unlocking Earth’s Hidden Power Revolution

“Inside the Next Wave of Geothermal Innovation: Opportunities, Risks, and Global Impact” By:  Robert Buluma An indepth interview with Cary Lindsey, PhD Research Scientist Great Basin Center for Geothermal Energy, Nevada Bureau of Mines and Geology, University of Nevada Reno  1. Enhanced Geothermal Systems (EGS) are often described as geothermal's "breakout technology." From a geological standpoint, what are the biggest unresolved uncertainties preventing large-scale commercial deployment ? The progress we've seen in EGS over the last few years has been incredible. For a long time, geothermal was largely limited to places where nature had already done the hard work for us by creating hot, permeable reservoirs. EGS opens the door to developing geothermal resources in places that were previously off the table. That said, there are still some big questions we need to answer. Can we maintain those engineered reservoirs for decades? How much liquid (water or brine) will the...

Gradient Geothermal and T5 Smackover Partners Forge Strategic Alliance to Advance Integrated Geothermal-Lithium Production in East Texas

The New Energy Frontier: How  Gradient Geothermal and  T5 Smackover Partners Are Reshaping East Texas By:  Robert Buluma Introduction: A Convergence of Energy and Minerals On June 22, 2026, Gradient Geothermal and  T5 Smackover Partners announced a collaboration that signals a fundamental shift in how the energy industry thinks about subsurface resources. The agreement, which brings Gradient's patented HXC Geothermal System to T5's phase one integrated geothermal project in East Texas, represents more than just another corporate partnership. It embodies a new model for energy development—one that treats geothermal brines not as a single-resource play but as a multi-stream opportunity capable of delivering baseload electricity, critical minerals, and industrial heat simultaneously. This analysis examines the collaboration between Gradient Geothermal and T5 Smackover Partners, the technological and geological context that makes it possible, and what this project me...
