AltaRock Suspends DOE-Backed Project

9/4/09Follow @gthuang

AltaRock Energy, a geothermal startup based in Sausalito, CA, and Seattle, announced earlier this week it has suspended drilling of a deep well in Northern California because of “geologic anomalies.” The well is part of a Department of Energy-funded demonstration project for AltaRock’s engineered geothermal system, which would create reservoirs of hot, subterranean water artificially. AltaRock said it is continuing to develop its technology and evaluating alternative well locations. AltaRock has raised about $30 million in venture funding from Vulcan Capital, Google, Khosla Ventures, Kleiner Perkins Caufield & Byers, and Advanced Technology Ventures.
