United States, Dec. 10 -- Mitsui & Co., Ltd. has decided an investment in Fervo Energy Company ("Fervo"), a U.S.-based developer of next-generation geothermal production technologies and projects.Geothermal power is attracting growing global attention as a renewable energy source capable of providing stable, weather-independent, round-the-clock electricity. Conventional geothermal development requires specific geological conditions such as natural permeability, which limits scalability and cost reductions. By contrast, one of the next-generation approaches-Enhanced Geothermal Systems (EGS)*-applies subsurface drilling techniques established through shale gas development, such as horizontal drilling and hydraulic fracturing. This enables lar...
