The Geothermal Battery Energy Storage (“GB”) concept has been proposed as a large-scale renewable energy storage method. This has been discussed in a previous white paper by the same authors, “Geothermal Battery Energy Storage” April 2020, (download original white paper); in reservoir calculations by Palash, McLennan, and Green, “Reservoir Temperature and Pressure Profiles for Geothermal Battery Energy Storage in Sedimentary Basins”, ARMA 54th Annual Symposium, 20-A-1411-ARMA, June 2020; and in an on-line NSF sponsored workshop conducted by University of Utah on May 19, 2020, “Large-scale Subsurface Seasonal Solar Heat Storage for Future Value”. This work has created significant interest in the use of high porosity and high permeability rock formations for subsurface large-scale and long-term heat storage. It has also led to questions and considerations naturally arising regarding subsurface heat storage, which this paper addresses. Download full “questions” paper.
