Fervo Energy and Vallourec have signed a five-year supply deal worth up to eight hundred million dollars. Vallourec will exclusively supply American-made steel tubes and premium connections for Fervo's next-generation geothermal wells. The deal supports Fervo's plan to build standardized fifty-megawatt geothermal power units called GeoBlocks across the United States. Investment in next-generation geothermal has grown more than five times since 2022, driven by rising demand for clean, round-the-clock power from data centers and electrification.
