Advanced geothermal startups are just getting warmed up

In a surprising twist amid political challenges, advanced geothermal startups are gaining momentum and forging ahead with significant developments. Despite setbacks to the Inflation Reduction Act last summer, these companies have managed to secure crucial support, showcasing the bipartisan appeal of renewable energy solutions. Fervo Energy, a Houston-based startup, has made headlines by selecting a supplier for essential components of its power plants. This marks a significant step toward advancing the second phase of the Cape Station project in Utah. The company has partnered with Baker Hughes to design and deliver five steam turbines, which are projected to generate a substantial 300 megawatts of electricity. This output is enough to power approximately 180,000 homes around the clock. Fervo Energy is not alone in its quest to harness geothermal energy. The company is among a group of startups that are innovating deeper drilling techniques, utilizing methods from the oil and gas sector to reach depths of nearly 16,000 feet. At this depth, the temperature is expected to remain consistently high at 520°F, providing a reliable source of renewable energy. Backing Fervo's ambitious plans is a robust financing package totaling $206 million, secured in June. This funding includes $100 million in project-level preferred equity from Breakthrough Energy Catalyst, a $60 million increase to an existing loan from Mercuria, and $45.6 million in bridge debt financing from an affiliate of X-Caliber Rural Capital. Notably, Chris Wright, the former energy secretary under Trump, played a role in Fervo’s investment when he was CEO of Liberty Energy in 2022. In a complementary move, fellow startup Sage Geosystems recently announced a partnership with geothermal developer Ormat Technologies. This collaboration aims to implement Sage’s innovative “Pressure Geothermal” technology at one of Ormat’s existing plants. The process involves injecting water into fractured rock under high pressure to absorb heat, and when the water returns, it harnesses both heat and pressure to drive turbines for electricity generation. With geothermal power plants capable of providing continuous energy, they have garnered attention from data center developers. A recent study suggests that this technology could potentially meet nearly two-thirds of data center energy demands by 2030, highlighting its growing significance in the renewable energy landscape.
