6 FAQs about [Malabo underground energy storage]

Is underground hydrogen storage a viable solution for large-scale energy storage?

This review paper provides a critical examination of underground hydrogen storage (UHS) as a viable solution for large-scale energy storage, surpassing 10 GWh capacities, and contrasts it with aboveground methods.

What is deep underground energy storage?

Deep underground energy storage is the use of deep underground spaces for large-scale energy storage, which is an important way to provide a stable supply of clean energy, enable a strategic petroleum reserve, and promote the peak shaving of natural gas.

Are underground reservoirs suitable for large-scale energy storage?

The underground reservoirs for large scale energy storage are described. An extensive review of the criteria for site screening underground reservoirs is done. Large-scale underground energy storage technologies and reservoir types are matched. General criteria to all reservoir types are assessed.

What is underground gravity energy storage (Uges)?

The proposed technology, called Underground Gravity Energy Storage (UGES), can discharge electricity by lowering large volumes of sand into an underground mine through the mine shaft.

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 ].

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.
