Bohr, Baby, Bohr! German Policies Support Enhanced Geothermal Drilling

Germany may have found the secret sauce that encourages new geothermal projects: policies that directly support drilling and financing the power plantóby lowering investor risks.

Germany's track record with geothermal electricity has been far less dynamic than its impressive history with wind and PV. Only 7.5 megawatts of geothermal electricity have been installed to date, compared to over 7,000 megawatts of PV installed in 2010 alone (and again in 2011).

Part of the reason is that Germany is pursuing emerging technologies such as enhanced geothermal systems (EGS) because it does not have a strong hydrothermal resource. EGS involves fracturing hot dry rock deep in the earth to create channels through which liquids can be circulated and heated. This heated liquid is used to generate electricity at lower temperatures, and may use a process such as the Organic Rankine Cycle. . .View Full Article
