GeoThermal energy along with hydroelectric are the only renewable energy sources that operate on a 24/7 basis. Intermittent energy generation from other renewables places a significant burden and need for new and large capacity energy storage schemes for electicial load balancing on a power grid. GeoThermal energy is generally located in ideal locations to utilize the existing formation permeability and natural geofluids for the power generation. Alternative geothermal systems have been reseached since the early 70`s especially hot dry rock as a geothermal source. The hot low permeable hot rock is conventional fractured with invasive fluids and thus the potential for induced seismicity can be significant. An example is the geothermal scheme in Basel, Switzerland, which has been shut down due to induced seismicity.
