GRANTS PASS, Ore. (AP) – Geothermal energy developers working on the flanks of an ancient Oregon volcano say they have taken an important technological step toward expanding geothermal energy from a small niche into a potential major source of homegrown power, but more work needs to be done.
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 >>
