Statoil is part of the Etzel gas storage in northern Germany. Gas is stored under high pressure in nineteen subterranean caverns created by washing out salt deposits more than 1,000 metres below ground.
As the cavern walls are impermeable to hydrocarbons, these structures are eminently suitable for gas storage.
The storage capacity is an important tool in ensuring reliable gas supplies when irregularities occur in the supply chain. The storage is also used as a means to maximise the value of Statoil’s gas.
The Etzel facility is tied to the Emden facilities and the Netra pipeline.
Statoil Deutschland Storage GmbH is the storage systems operator for its share of the facility.
