Abrégé

Disclosed is a pneumatic membrane gasometer for the storage of hydrogen gas at low pressure. The gasometer includes: a first bag-shaped membrane delimiting a hydrogen storage chamber; a second membrane partially delimiting a pressurization chamber superimposed, at least in part, on the storage chamber; a third membrane, placed resting on top of the first membrane, fixed in an impermeable manner at least to the second membrane, defining, with the first membrane, a cavity open towards the outside of the gasometer; hydrogen supply and discharge unit associated with the storage chamber; pressurization unit; mechanical anchor to a base surface of the first, second and third membranes; and a natural passive ventilation system to vent any hydrogen losses to the outside, including a duct adapted to connect cavity to the outside environment passing through the pressurization chamber.

Abrégé

The present invention relates to the industrial field of gas storage plants, and more in particular concerns a modular element (100) adapted to be used for the construction of an anchoring base for a membrane gasometer, of hemispherical or spherical dome type, utilizable in particular for storing biogas generated by sludge or slurry digestion. Said modular element (100) is in the shape of an upside down T and comprises: • - a first (1) and a second (2) L-shaped semi-module, each comprising a vertical wall (11, 21) and a supporting foot (12, 22), adapted to be associated with each other by means of screw connection means at respective vertical walls (11, 21); • - an edge beam (3), adapted to be associated with at least one of said semi-modules (1, 2) by means of screw connection means. Said first (1) and second (2) semi-module and said edge beam (3) are made of sheet metal cut and bent and without any welds. The invention also relates to a polygonal shaped anchoring base for a membrane gasometer produced with a plurality of said modular elements
