AltaRock Energy, Inc., of Seattle, says the data is still being analyzed, but they are confident they have created three geothermal reservoirs from a single well where none existed before. The breakthrough solves two problems holding back the next level of geothermal development, known as Enhanced Geothermal Systems, or EGS: creating reservoirs big enough for commercial production in places they don’t occur naturally, and holding down costs.1 2 3 next >>
