6 FAQs about [Domestic reservoir energy storage]
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.
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 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.
Can geological reservoirs be used for energy storage?
Electric energy storage technologies, involving the use of geological reservoirs offer large storage capacities and discharge rates [ 6 ], bringing all the advantages of a large-scale energy storage system while minimising environmental and social impacts, and the need for surface space.
What are the different types of subsurface energy storage?
Subsurface energy storage options including natural gas storage, compressed air storage, pumped hydroelectric storage, and geothermal storage; each requiring additional geologic investigations and potential future assessments of available storage resources.
How much storage is needed for a large-area electricity network?
An approximate rule of thumb for the amount of storage needed to support a large-area electricity network with high levels of variable solar and wind is 1 d (24 h) of energy consumption. This allows the day-night cycle of solar energy output to be accommodated. This storage could be a combination of pumped hydro and batteries.
