Advanced geological mapping and subsurface drilling tools must still be developed in order for geothermal powerto become a more prominent source of renewable energy, experts said at the National Geothermal Summit.
In a breakout session at the summit on Wednesday, Aug. 8, a panel of government and private-sector geothermal experts discussed the value that additional 3-D modeling, geophysical surveys to indicate hot water flow below ground, and other research and development work could have on the future of geothermal exploration.
James Faulds, director of the Nevada Bureau of Mines and Geology, said that like oil and gas deposits, about two-thirds of the geothermal energy sources remain hidden, with no surface expression. Advanced technologies for fossil fuels has been developed, but similar advancements for geothermal have lagged behind… Read more
