Endurance Energy Tests the World's First Subsea Geothermal Well: What the Axial Seamount Demonstration Really Proved What if geothermal energy did not need a power plant on land? What if electricity could be produced directly from the Earth's heat beneath the ocean, with generators sitting on the seafloor and sending power to coastal grids? On October 19, 2026, Seattle-based startup Endurance Energy announced a major step toward that idea. The company said it had drilled and completed the world's first subsea geothermal well and placed a 3-ton test power plant nearly a mile beneath the Pacific. It also reported net-positive electricity from heat at an active underwater volcano, according to its announcement on PR Newswire. The headline numbers are modest. The Adélie prototype produced more electricity than it used for about 8.7 seconds. During that time it delivered a median net output of about 2 kilowatts and a peak of 16.5 kilowatts. One detail matters more than any other...
Fervo Energy Secures Landmark 320 MW Power Purchase Agreements with Southern California Edison By: Robert Buluma In a move that underscores the growing demand for sustainable energy solutions, Fervo Energy, a pioneer in next-generation geothermal technology, has announced two monumental power purchase agreements (PPAs) with Southern California Edison (SCE). Totalling 320 MW, these agreements represent the world's largest geothermal PPAs to date, cementing geothermal energy's critical role in the transition to a cleaner energy future. A Milestone in Clean Energy Set against the backdrop of California's ambitious clean energy goals, the 15-year agreements will see SCE purchasing 24/7 carbon-free geothermal energy from Fervo's Cape Station project in southwest Utah. This power will serve approximately 350,000 homes across Southern California, bolstering the state's grid reliability with a steady supply of renewable energy. David Hochschild, Chair of the California Ener...
