Geothermal Reservoir Stimulation Fluid

Caption

Pacific Northwest National Laboratory's new geothermal stimulation fluid could make geothermal power production more environmentally friendly and less costly where conventional geothermal doesn't work. The nontoxic fluid is designed to be used in enhanced geothermal systems, where fluids are injected into drilled wells that lead to underground geothermal reservoirs. The fluid expands when exposed to carbon dioxide underground, which creates tiny, but deep cracks in otherwise impermeable rock.
