Revolutionizing the Depths: How GEOLOG's Strategic Acquisition is Supercharging Geothermal Energy's Future By: Robert Buluma Imagine plunging miles beneath the Earth's surface, tapping into an ancient furnace of heat that never sleeps, never falters, and never runs out. This is geothermal energy—the planet's own endless battery, capable of powering civilizations with clean, reliable electricity around the clock. While solar panels go dark at night and wind turbines stand idle in calm air, geothermal delivers baseload power with capacity factors often above 90%. In a world racing toward net-zero emissions and facing exploding energy demands from data centers, electric vehicles, and industrial growth, geothermal is emerging as the sleeping giant ready to awaken. Scaling geothermal globally, however, is no simple task. Drilling deep into the crust exposes crews to extreme conditions: temperatures soaring past 300°C, highly corrosive fluids, and rock so hard it can destroy...

NASEO Launches Multistate Geothermal Power Accelerator: A Major Step Toward Clean, Reliable Energy By:  Robert Buluma In a significant boost for America's clean energy future, the National Association of State Energy Officials (NASEO) announced on December 18, 2025, the launch of the NASEO Geothermal Power Accelerator. This collaborative initiative brings together 13 states to fast-track the development of geothermal power in partnership with the private sector. Funded by the U.S. Department of Energy’s Geothermal Technologies Office and NASEO itself, the Accelerator aims to unlock the vast potential of geothermal energy a reliable, firm, and flexible source of clean power available around the clock. The participating states are Arizona, California, Colorado, Hawaii, Idaho, Louisiana, Montana, Nevada, New Mexico, Oregon, Pennsylvania, Utah, and West Virginia. These diverse regions, spanning traditional geothermal hotspots in the West to emerging opportunities in the East, will wo...

Fervo Energy's $462 Million Geothermal Gold Rush: Google Joins the Heat By:  Robert Buluma December 10, 2025 In the fast-evolving world of clean energy, where solar panels dominate skylines and wind farms stretch across horizons, a deeper and quieter revolution is rising from beneath our feet. Fervo Energy, the Houston-based innovator in enhanced geothermal systems (EGS), has just announced an astonishing $462 million Series E funding round. This isn’t just another climate-tech investment,it's a tectonic moment for geothermal energy. The round was led by   B Capital , joined by major players including Google , Tesla co-founder JB Straubel, and nuclear industry leader Kris Singh. With continued backing from Breakthrough Energy Ventures and Devon Energy, Fervo’s total funding now exceeds $1.5 billion. Why the sudden rush? As AI-driven data centers consume unprecedented amounts of electricity and political winds shift around renewable priorities, geothermal’s promise of 2...

Exergy’s  Gemini Turbine: Redefining the Future of Large-Scale Geothermal Power By:  Robert Buluma In a bold leap forward for geothermal innovation, Exergy International has once again raised the bar with the unveiling of its groundbreaking Gemini Turbine — a next-generation powerhouse that delivers up to 60 MWe on a single shaft . Announced in Olgiate Olona, Italy , the Gemini marks a monumental evolution in Exergy’s proprietary Radial Outflow Turbine (ROT) technology, setting a new benchmark for efficiency, scalability, and cost-effectiveness in large-scale geothermal power generation . The Dual-Engine Revolution At the core of Gemini’s innovation is a reimagined turbine architecture that merges two turbines into one high-capacity unit . Its dual-inlet design allows working fluid to enter symmetrically from both sides, expanding radially outward through a central rotor disk equipped with mirrored rotor stages. This unique configuration achieves unmatched mechanical b...

  Mazama Energy Ignites a New Era: The World’s Hottest Geothermal System Powers Toward a Carbon-Free Future By Robert Buluma , October 2025 In a quiet corner of Oregon’s Cascade Range, deep beneath the rugged volcanic landscape of Newberry, a new energy revolution is taking shape.  Mazama Energy — a startup incubated by Khosla Ventures and backed by Gates Frontier — has just achieved a technological milestone that could change the way we power the planet. At a staggering 629 °F (331 °C), Mazama’s newly completed Enhanced Geothermal System (EGS) is now the hottest ever recorded on Earth. And this is just the beginning. By 2026, the company expects to push those temperatures to 750 °F (400 °C) — unlocking enough energy to power gigawatts of clean electricity from this single site. 🔥 Cracking the Code of the Earth’s Heat For decades, geothermal energy has been the “quiet cousin” of renewables — clean, reliable, but limited to places where hot water naturally flows near the sur...

Fervo Energy Pushes Boundaries with 15,000-FT, 500°F Geothermal Well — Ushering in a New Era for Enhanced Geothermal Systems June 10, 2025 – By Robert Buluma In a stunning feat of engineering and innovation, Fervo Energy has announced the successful drilling and logging of its Sugarloaf appraisal well, marking a monumental leap in the advancement of Enhanced Geothermal Systems (EGS).
