Mine park energy storage reservoir

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.

How can abandoned mine facilities be used to generate energy?

Finally, a CAES plant could be established, using the upper mine galleries for underground air storage; the fact that Lieres is a “dry mine” is ideal for this type of system. Thus, the abandoned mine facilities are efficiently used to generate both electrical and thermal renewable energy. Fig. 5.

What are potential storage reservoir sites in the geological underground?

Potential storage reservoir sites in the geological underground mainly comprise salt caverns, saline aquifers, depleted hydrocarbon reservoirs and rock caverns. Adapted from [ 22 ]. Essentially, a geological reservoir is prepared prior to injection, to effectively create an underground, pressurised storage container.

How a reservoir can be used to store energy?

A reservoir made in a porous and permeable underground formation can be used to store Natural Gas, CO 2, Air, Hydrogen or even Thermal Energy. Storage of an energy carrying fluid requires a phase of compression and injection in gaseous state into the reservoir: the free-phase gas pushes the formation water away from the injection wells.

Can underground space energy storage technology be used in abandoned coal mines?

The underground space resources of abandoned coal mines in China are quite abundant, and the research and development of underground space energy storage technology in coal mines have many benefits.

What is rock cavern thermal energy storage?

Rock Cavern Thermal Energy Storage (CTES) resorts to engineered rock caverns as the underground water reservoir ( Fig. 6 ). Caverns can be mined specifically to serve as TES reservoirs, but CTES can also be accomplished by recommissioning abandoned mines.
