Dynamic Earth Energy Storage: Terawatt-Year, Grid-Scale Energy Storage using Planet Earth as a Thermal Battery (GeoTES): Seedling Project Final Report

Publicly accessible License 

Grid-scale energy storage has been identified as a needed technology to support the continued build-out of intermittent renewable energy resources. As of April 2017, the U.S. had approximately 24.2 GW of energy storage on line, compared to 1,081 GW of installed generation capacity (Litynski et al. 2006, Hellstrom 2003). This represents a large shortfall of the storage needed to stabilize the U.S. grids with the rising penetration of renewable energy. Our team proposed to address this shortfall through the storage of excess energy as geothermal brine in deep geologic formations. This concept, known as geologic thermal energy storage (GeoTES), relies on the storage of thermal energy in geologic formations for recovery and use in large-scale direct use geothermal applications. As such, GeoTES has the potential to play a significant role in meeting the energy storage shortfall in the coming decades by assisting with peak demand ramping, easing stress on transmission, providing regional storage to support sustainable direct use geothermal applications, and providing a variety of grid stabilization benefits due to renewable outages or inaccurate forecasting and rotor stability.
