Our types of storage facilities

As an active player in the energy transition, Storengy provides its global industrial clients with innovative energy storage solutions.

Storage in aquifers

Aquifer storage involves injecting natural gas into the rock under pressure and at great depth. The gas progressively displaces the water without changing the underground architecture. A true natural reservoir, the dome-shaped structure is crowned with a tight cap rock which ensures that gas is kept underground.

Storage in salt caverns

Salt cavern storage involves a series of caverns dug in deep, thick layers of rock salt. The caverns are created by injecting water to progressively dissolve part of the salt which is then extracted as brine. There is then room for natural gas, which is injected at high pressure and stored as a gas. Impermeable and non-porous, these caverns are remarkably waterproof.

Storage in depleted reservoirs

Depleted firlds are depleted natural gas or oil fields that can then be converted into underground storage sites. This involves reinjecting natural gas into a geological structure which has already stored hydrocarbons over several million years.

Storage in lined rock caverns

Storage in lined rock caverns is an innovative technology for storing natural gas at high pressure and shallow depth in rock caverns excavated in hard rock masses. They are equipped with a special steel liner with high mechanical resistance.
