About
Founded in 2007, AltaRock Energy is a private headquartered in Seattle, United States specializing in Geothermal.
AltaRock Energy is a technology company focused on advancing Enhanced Geothermal Systems (EGS) development, with emphasis on SuperHot Rock (SHR) geothermal resources. SuperHot Rock exploits supercritical water conditions (375°C, >220 atm) in engineered reservoirs to achieve 5-10 times the energy density of conventional geothermal wells. The company develops technologies across drilling, well completion, reservoir engineering, and power conversion. AltaRock's primary demonstration site is Newberry Volcano in Oregon, where the company plans to develop the world's first SHR power plant. Key technical focus areas include non-mechanical drilling methods (plasma, millimeter wave), advanced high-temperature materials, reservoir stimulation and characterization, and system integration. The company partners with organizations including Pacific Northwest National Laboratory, Oak Ridge National Labs, Stanford University, Oregon State University, and drilling technology developers like Quaise Energy. AltaRock positions SHR as offering superior economics (claimed LCOE of $0.05/kWh) and environmental benefits compared to conventional geothermal, solar, wind, and other alternatives, while requiring minimal transmission infrastructure and water usage.
