The US Energy Department has announced plans to fund enhanced geothermic system (EGS) projects conducted by Sandia National Laboratories and the University of Utah.
Under the Frontier Observatory for Research in Geothermal Energy (FORGE) programme, a total of $29m will be offered to instrument, characterise, and permit an underground laboratory to conduct EGS research.
Sandia National Laboratories' team will work on a site in Nevada, while the University of Utah focuses on Utah.
Undersecretary for Science and Energy Franklin Orr said: “Enhanced Geothermal Systems can help us tap into a vast energy resource with the potential to generate enough clean energy to power millions of homes.
“In supporting this technology, the FORGE programme is advancing American leadership in clean energy innovation and could ultimately help us meet our climate and sustainability goals.”
The funding was granted following a competitive first phase of research to evaluate potential EGS sites.
EGS can offer access to carbon-free sources of clean energy by using the earth's heat.
