Salt caverns offer an effective underground storage solution, both technically and economically, with proven feasibility. They help maintain security of supply and fluctuations in supply and demand. Furthermore, the storage of green and low-carbon energy in onshore salt caverns can help reduce dependence on foreign countries for our energy supplies, strengthen strategic autonomy, and support a more sustainable industry. 

In the future, different forms of energy storage will be needed to make optimal use of renewable energy. These include long-term storage of gas and hydrogen, short-term storage in batteries, and medium-term storage, such as compressed air. Hydrogen storage is becoming increasingly important, partly to make better use of wind energy and partly for use as a feedstock in industrial processes.  

Nobian is involved in the development of large-scale energy storage in salt caverns, with completed projects as well as ongoing and future initiatives. In Zuidwending, the Netherlands, we have already developed several caverns for natural gas storage for storage operator EnergyStock (Gasunie). Together with EnergyStock, Nobian is currently preparing the potential development of similar caverns for hydrogen storage as part of the Hystock project. 

In Denmark, Nobian and Gas Storage Denmark have signed a Memorandum of Understanding (MoU) to explore potential cooperation in the development of energy storage caverns in Denmark.
