| Storage of Natural Gas
| Natural gas storage guarantees a flexible energy supply at times of peak demand.
Underground storage in porous formations and in salt caverns provides a technology that combines large storage capacities with low investment and operational costs, the highest level of safety, and
little environmental impact.
In handling peaks of energy consumption, salt caverns feature the advantages of high withdrawal rates and small amounts of ’cushion gas’ (the amount of gas which has to remain permanently stored) compared to porous formation storages.
Moreover, the storage capacity of a cavern plant can at any time be enlarged through renewed leaching
or construction of new caverns.
