Geothermal

Spatial map depicting mean geothermal heat flow in and around Greenland derived from machine learning results. Heat anomalies appear off the coast of the capital area in the southwest, which might be interesting in relation to harvesting geothermal energy. In general, though, the heat flow from beneath Greenland is lower than previously estimated. Credit: Colgan and Wansing, 2022 In our understanding of global geothermal heat…

Team collaborates on assembling and testing “rock star” system 4,100 feet undergroundA team of scientists has assembled a first-of-its-kind system to help them understand how to harness energy from deep below ground.The Stimulation and Flow System is the newest “rock star” from Pacific Northwest National Laboratory (PNNL) and its partners, designed to investigate how water travels underground through extremely hot rock and subsequently transmits heat to the surface.The new system is part of the Enhanced Geothermal…
