As one of Europe‘s largest gas storage operators, Uniper Energy Storage enables a reliable and flexible energy supply.

Uniper Energy Storage GmbH is an independent company and offers access to 9 underground gas storage facilities in Germany, Austria and the UK with a total capacity of 80 TWh, which are connected to four market areas. 

Gas storage is key to the energy transition

Natural gas forms an important bridge between fossil and climate-friendly energy. The growing share of renewable energies in the energy mix will require the storage of large amounts of energy in the future, because sun and wind are not always available. This green electricity can be transformed into hydrogen by electrolysis and so stored in large gas storage facilities.

With a pioneering spirit and decades of experience, Uniper Energy Storage is pushing to decarbonize the energy industry to ensure security of supply in the future through the storage of natural gas, hydrogen and other green gases.

We empower energy evolution!

How does gas storage work?

Large amounts of gas are stored in underground gas storage facilities in the summer months so that they are reliably available in the cold winter months. Uniper Energy Storage uses salt caverns, for example, which can be up to 700m high - about twice as high as the Eiffel Tower. The gas can be stored there safely and efficiently over a long period of time.
