Over fifty years in Etzel

For over five decades STORAG ETZEL has been operating the Cavern Facility at Etzel. A huge amount of crude oil and natural gas is stored in the 75 underground storage caverns.

The artificially created cavities in the salt dome contribute to an important part of a stable and safe energy supply of Germany and Western Europe. A big amount of the oil stockpiling obligation is stored in the caverns here at Etzel.

The crude oil and natural gas storage is capable to balance the German energy market in the event of a supply shortage for a certain period or in case of seasonal or peak demand.

Do you need more information? Here you’ll find a brief presentation of our history or just call us under ++49 4465 809 - 0 (operator).
