Important Geothermal Technology Breakthrough

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, reports Jeff Barnard at the Associated Press.  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, a first ever in the world. 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. These new frontiers have hot rocks, but no cracks in them to deliver the steam. That’s where EGS comes in, creating cracks in rocks. Company president Susan Petty said that more analysis and testing are needed to show if the reservoirs are good enough for commercial power production in the future, by using steam from the reservoirs to spin turbines to generate electricity.

Join the swelling numbers of voters TELLING Congress they’ll vote for Clean Energy candidates here: http://signon.org/sign/we-are-the-clean-99?source=c.em.cp&r_by=487176 . This is an ongoing campaign (the next Congressional election is in 2 years!) so please, spread the word. It’s our way of telling Congress that a strong clean energy voting bloc is out there. This is how YOU can make a difference.
