Is underground storage a viable green solution?
Underground storage for renewable energy resources could be a viable green solution as we transition to a net zero UK. Some renewable energy sources, like wind power, are intermittent and any excess energy can be difficult to store. BGS © UKRI.
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 underground thermal energy storage?
Underground Thermal Energy Storage (UTES) A thermal energy storage is a system that can store thermal energy by cooling, heating, melting, solidifying or vaporizing a material , such as hot-water, molten-salt or a phase-change material. Sensible heat storage (SHS) relies on the temperature variation of a solid or liquid (e.g. water).
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.
Why is the underground a good place to store thermal energy?
The underground is suitable for thermal energy storage because it has high thermal inertia, i.e. if undisturbed below 10-15 m depth, the ground temperature is weakly affected by local above ground climate variations and maintains a stable temperature [76, 77, 78].
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.
