Geothermal-based energy storage company EarthBridge Energy has secured land rights to deploy its technology in Texas.

The Texas General Land Office issued a geothermal lease to EarthBridge in West Texas, the company announced earlier this week (2 May).

EarthBridge said it now plans to deploy its GeoBattery energy storage technology as part of a new, hybrid energy development combining additional, on-site renewable energy resources.

CEO Derek Adams, PhD said: 
“This marks an important step in EarthBridge’s strategy to deploy geothermal energy storage assets across the US and adds a key project to our portfolio.”

The company’s system will absorb excess electricity from wind and solar farms and store it for 10-1000+ hours, feeding it back to the grid when it is needed.

The system stores heat energy in subsurface reservoirs and converts it back to electricity using a high-efficiency turbine. The technology brings the installed cost of long-duration energy storage (LDES) below $10/kWh and enables the deployment of 100% carbon-free energy at scale, EarthBridge claimed.
