The United States Department of Energy (DOE) has announced an investment of up to $31m to support six innovative renewable geothermal energy projects across the country.
These initiatives aim to advance enhanced geothermal systems (EGS) and explore new methods of energy storage, aligning with the US’ broader goals of reducing emissions and bolstering the clean energy sector.
Secretary of Energy Jennifer Granholm emphasised the significance of the initiative: “Expanding the use of new and innovative geothermal technologies will allow the United States to continue pushing forward into the frontier of the clean energy revolution by using the heat beneath our feet.”
Revolutionising geothermal energy
Currently, geothermal energy contributes around four gigawatts to the US electricity grid. However, the DOE estimates that the expansion of EGS could unlock up to 90 gigawatts of reliable, flexible power by 2050, enough to supply…
