A volcano in Oregon is going to be used in a demonstration project for applying geothermal energy. Steam will be produced at great depths and used to generate electricity. The heat is there, open question though is whether it will be possible to establish a circulation of water in the system. Engineers are working on a new technology called Enhanced Geothermal Systems (EGS). Wells are going to be drilled deep into the rock, water will be pumped in and steam will return. Some concerns regarding artificial earth quakes exist. Additionally it is difficult to scale the technology. Two small EGS plants already exist in Germany and France. Participants are DoE and Google, amongst others. EGS is attractive because it vastly expands the potential for geothermal power. Currently geothermal sources are used to generate 0.3% of the electricity in the US. EGS could bump this to 10% in 50 years time. A 2008 USGS assessment found EGS throughout the West, where hot rocks are closer to the surface than in the East, has the potential to produce half the country’s electricity.
