The (B)storage is a biogas storage bag with a capacity of 2.000 L. It fills up with biogas through pressure equalization between the bag and any biogas digester. The 4 loops at the corners of the bag allow it to be secured against wind.

To use the gas from the bag either the bag is weighted down or a biogas pump is connected. Usually a weight of the same size as the bag, for example a ladder or similar wood contraction, is placed on the bag to push out the gas.


The (B)storage is equipped with a 1/2″ inside threaded flange, a ball valve and 4 corner straps. Upon request the thread can also be 3/4″ or 1″ and the number of straps is variable.
