The Geothermal Battery Energy Storage ("GB") concept relies on using the earth as a storage container for heat. The concept of the subsurface storing heat is not new. What is new is using a small volume of high porosity and high permeability water saturated rock, away from complex layering and fractures and faulting.
The battery heat is generated in the internal resistance of each cell and all the connections (i.e. terminal welding spots, metal foils, wires, connectors, etc.). You''ll need an estimation of these, in order to calculate the total battery power to be dissipated …
