Oil & Gas Storage
Advantages of oil storage in caverns
In the Etzel salt dome, we operate 24 caverns for the storage of oil. Due to the large available cavity volume and the low operating costs compared to aboveground tank storage, caverns are excellently suited for the long-term storage of crude oil.
Therefore, caverns are particularly used for the storage of the legal crisis stockpile requirement of some European countries. The facility is connected via a 44" long-distance pipeline (110 cm) to the NWO oil port in Wilhelmshaven, which is about 25 km away from Etzel.
Ready for the future
The Etzel site is ready for the future: In addition to storing fossil fuels such as oil and natural gas, renewable energies can also be stored in caverns, e.g. by converting surplus electricity into hydrogen (H2) or synthetic natural gas (SNG = methane).
The operator STORAG ETZEL has already successfully converted oil caverns to gas storage in its operating history. In the context of the energy transition and decarbonization, the conversion of underground storage facilities from gas / oil to hydrogen is currently being investigated in the "H2CAST Etzel" project.
