IT’S A LAW OF NATURE TO STORE EXISTENTIAL THINGS SAFELY UNDERGROUND.

Decide for crude oil storage in caverns!
We are ready to store your crude oil
STORAG Etzel is one of the largest independent storage companies in Europe and offers sustainable storage solutions.
We have been building, maintaining and leasing bulk underground storage capacity for gas and oil since 1971 in the Etzel salt dome near Wilhelmshaven. The caverns are leased by well-known energy trading companies as well as oil stockholding organisations of various European countries. With a storage volume of more than 10 million cubic metres spread over 24 caverns, STORAG ETZEL operates one of the largest crude oil storage facilities in Europe. The storage facility has an approved expansion potential up to a total of 99 caverns. The cavern facility is connected to the gas grid and via our oil pipeline to Wilhelmshaven. Around 1/6 of Germany’s gas reserves are stored within the Etzel salt dome.

builds, operates and manages oil and gas caverns in northern Germany – with more than 50 years of experience
caverns for oil, and 51 caverns for gas and potential for 24 new caverns
Acting on behalf of German institutional investors (insurance industry, pension funds, etc.)
Connected via pipeline to deep-water port of Wilhelmshaven
LOTS OF EXPERIENCE. MANY ADVANTAGES.
Our oil storage in caverns represents a sustainable solution for efficient, secure and environmentally friendly oil storage.

VALUABLE BENEFITS
The oil storage in caverns combines a structural cost advantage with outstanding efficiency, safety and environmental friendliness.
The use of underground caverns not only enables a cost-effective infrastructure but also sustainable operational management. An outstanding feature is the extremely low volume loss rate, thanks to specially designed caverns that ensure precise and secure oil storage, minimising resource losses. In contrast to conventionaltank farms, we make a stand against quality losses by avoiding evaporation effects, guaranteeing the unchanged quality of the stored oil. The safety of our underground storage not only minimises the above-ground attack surface but also creates a robust protective environment for the stored oil. Our offering also has the benefit of a higher capacity compared to conventional solutions.
OIL STORAGE
In the early 1970s, after extensive underground exploration, the Etzel salt dome was chosen for the construction of salt caverns due to its favourable conditions.
The salt dome is approximately 12 kilometres long and five kilometres wide, extending from a depth of over 4,000 metres to 750 metres below the surface. The decision to establish a strategic oil reserve was made in the 1970s to ensure a continuous energy supply in the event of future political crises or natural disasters in oil-producing areas. STORAG ETZEL, one of Europe’s largest crude oil storage companies, has 24 caverns with a total capacity of around 11 million cubic metres for long-term storage. The stored crude oil is available to stockpiling organisations of various European states during energy crises and serves as part of Germany's national reserve.
CAVERN VOLUME ILLUSTRATED

The caverns are artificially leached into a salt dome. They have the capacity of two supertankers.
The oil caverns are used by stockholding institutions and commodity traders
Total pipeline capacity to Wilhelmshaven up to 6,000 m3/h
Injection and withdrawal rate approx. 350 m3/h per cavern
