Double membrane gas storage
The innovative solution for biogas plants
Double membrane gas holders offer an innovative solution for the safe and efficient storage of biogas.
A double membrane gas holder is a flexible gas storage system consisting of two separate membranes. The inner membrane stores the gas, while the outer membrane is stabilised by the supporting air pressure and provides weather protection. The air-filled space in between provides the necessary stability, enabling safe and adaptable gas storage.
