New geothermal heat extraction process to deliver clean power generation

PNNL's advanced heat recovery method makes most of low-temp 'hot rock' resources

RICHLAND, Wash. – A new method for capturing significantly more heat from low-temperature geothermal resources holds promise for generating virtually pollution-free electrical energy. Scientists at the Department of Energy's Pacific Northwest National Laboratory will determine if their innovative approach can safely and economically extract and convert heat from vast untapped geothermal resources.
