Learn MoreThermal 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.
4.1.6. Geotechnical criteria Geotechnical criteria are related to the construction phase of underground energy storage and include thermal and mechanical rock properties, usually requiring in situ tests to assess the cavern stability.
The scope is geared to the specific requirements of the gas storage facility and the connected pipeline network. The natural gas taken from the pipeline system is monitored regarding quantity and quality and it is injected into the storage reservoir using a compressor station.
The general layout of underground storages depends on geological conditions as well as on demands of the connected pipeline or network. The decision to utilize an underground reservoir for storing natural gas involves correspon-ding geological characteristics and extensive studies with regard to the relevant technological and economic conditions.
Criteria for selecting underground reservoirs are very important for the success of an energy storage facility. Those criteria should consider land surface constraints as well as subsurface information.
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.
