What are the different types of energy storage technologies?

The technologies considered in this article are: Underground Gas Storage (UGS), Underground Hydrogen Storage (UHS), Compressed Air Energy Storage (CAES), Underground Pumped Hydro Storage (UPHS) and Underground Thermal Energy Storage (UTES).

What are the different types of underground energy storage technologies?

For these different types of underground energy storage technologies there are several suitable geological reservoirs, namely: depleted hydrocarbon reservoirs, porous aquifers, salt formations, engineered rock caverns in host rocks and abandoned mines.

What is a super energy storage device?

The process of devising a super energy storage device by hybridizing together two or more storage systems having complementary characteristics are defined as a HESS. The major objectives are coping with real-time harsh working environments that a single device is unable to do.

Can underground energy storage systems be mined?

On one hand, during construction or operation of underground energy storage systems, water inflow could be so great that mining or operation would be impossible. On the other hand, in arid regions or within the unsaturated zone, absence of both capillary water and water at hydrostatic head may prevent storage within a mined cavern.

How do superconductors store energy?

The mechanism of energy storage in these devices is based on the principle of electromagnetic induction, where an electric current flowing through a superconducting material induces a magnetic field, which in turn stores energy.

What is underground thermal energy storage (SHS)?

SHS can be developed at a small-scale (<10 MW) above surface technology or at a large-scale system in the subsurface. Underground Thermal Energy Storage (UTES) is a form of energy storage that provides large-scale seasonal storage of cold and heat in underground reservoirs [ 74, 75, 76, 77 ].
