6 FAQs about [How to calculate geotechnical energy storage]

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 a borehole thermal energy storage system (BTES)?

Borehole thermal energy storage (BTES) system If it is not possible to extract energy from an adequate aquifer, then one option that might be considered is a borehole thermal energy storage system (BTES).

How is thermal energy stored in boreholes?

The storage of thermal energy in boreholes is accomplished by using vertical heat exchangers buried anywhere from 20 to 300 m below the earth's surface. This facilitates the flow of heat energy into and out of the ground (clay, rock, sand, etc.) .

Can geothermal energy storage be used in large-scale energy storage?

The Geothermal Energy Storage concept has been put forward as a possibility to store renewable energy on a large scale. The paper discusses the potential of UTES in large-scale energy storage and its integration with geothermal power plants despite the need for specific geological formations and high initial costs.

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.

Should thermal energy storage be confined to the ground surface?

Thus, depending on the time perspective of thermal energy storage, modelling suggests that particular attention should be paid to the ground surface above the BTES array and that, in some cases, it may be desirable to minimise the area of the surface footprint through which heat can be lost, or to insulate the surface footprint.
