Why is energy storage important in the geological subsurface?
Energy storage in the geological subsurface provides large potential capacities to bridge temporal gaps between periods of production of solar or wind power and consumer demand and may also help to relieve the power grids.
How do geotechnical engineers work with energy storage?
Geotechnical engineers have been involved with energy storage through the design of reservoirs for pumped-hydro energy storage, where water is pumped to a reservoir with higher elevation during times when electricity costs are low, and electricity is generated through hydro-power.
What is used subsurface space in Geotechnical Energy Storage?
Three categories of used subsurface space have been identified and developed in the ANGUS+ project in the context of geotechnical energy storage: firstly, the “operational space” (Fig. 2 ), i.e., the space directly used by the storage operation, which comprises the technical installations and the space taken up by the injected gas or heat.
How can thermal energy storage be adapted in geological settings?
