Traditional deep geothermal systems are thermally imbalanced and experience thermal decline over time.  Shallow geothermal systems (i.e., ground source heat pumps) require a balanced thermal load to maintain efficiency.  Recent work in North America and Europe is exploring the potential of Aquifer Thermal Energy Storage (ATES), Reservoir Thermal Energy Storage (RTES) and Synthetic Geothermal Reservoirs (SGR) for a variety of scenarios, including diurnal and seasonal thermal storage.  While this may not improve the operation of baseload power production, it could significantly improve operations for dispatchable systems and to meet demand using smaller systems.
