6 FAQs about [Illustration of the underground energy storage station disposal process]

What is safety in a geological disposal facility?

Safety in the context of a geological disposal facility addresses the packaging of waste, the transport of the waste from storage to the facility as well as the construction and operation of the facility and safety in the long term after the facility has been closed.

How is thermal energy added to a storage tank/store buried underground?

Thermal energy is added to or removed from the insulated tank/store buried underground by pumping water into or out of the storage unit. Excess heat is used to heat up the water inside the storage tank during the charging cycle. Hot water is taken from the top of the insulated tank/store and used for heating purpose during the discharging cycle.

How to choose a site for underground energy storage?

The site selection for underground energy storage is dependent upon several factors, mainly related to geological and engineering issues, such as: the type of candidate rocks, structural issues, tectonics and seismicity issues, hydrogeological and geothermal issues and also geotechnical criteria.

Why is stress important in an underground excavation for energy storage?

This natural state of stress, in conjunction with the strength and structural characteristics of the rock, is important in determining the orientation, geometric shape, and dimensions of an underground excavation for energy storage .

How does an underground energy storage cavern prevent fluid from escaping?

According to van Gessel et al. , in an underground energy storage cavern, the stored fluid is prevented from escaping on the principle of hydraulic containment: the cavities are located at such a depth that the hydrostatic pressure is greater than the pressure of the stored product.

What should be considered when evaluating large-scale underground energy storage reservoirs?

Thermal and thermodynamics properties and behaviour of the rocks should also be considered as part of the studies developed when evaluating large-scale underground energy storage reservoirs.
