    Abstract: A storage plant for liquefied gas, in particular Liquefied Natural Gas (LNG), including at least one tank (1 ) with sidewalls (2) and bottom (3)/roof (7) for storage of the liquid and means such as pipes and pumps for circulation and/or filling and emptying of the tank. The storage tank (1 ) is provided in a cavern (4) in the ground, preferably in solid rock (6) below the ground water level (5), whereby an inert gas, preferably N2, is provided in the cavern (4) surrounding the tank and with a controllable pressure preferably kept slightly above the vapour pressure of the liquefied gas in the tank. The roof (7) may be made of a vertically, depending on the filling height of the LNG within the tank, movable closure (7). The closure (7) may in turn be made of one or more floating elements (8) forming a flexible floating "blanket", floating on the liquid in the tank, and provided with a seal (9) between the blanket and tank walls (2).

    Abstract: An electrochemically active hydrogen diffusion barrier (2), which comprises an anode layer (6'), a cathode layer (6''), and an intermediate electrolyte layer (8), which is conductive to protons and substantially impermeable to hydrogen. A catalytic metal present in or adjacent to the anode layer (6') catalyzes an electrochemical reaction that converts any hydrogen that diffuses through the electrolyte layer (8) to protons and electrons. The protons and electrons are transported to the cathode layer (6'') and reacted to form hydrogen. The hydrogen diffusion barrier (2) is applied to a polymeric substrate (12) used in a storage tank to store hydrogen under high pressure. A storage tank equipped with the electrochemically active hydrogen diffusion barrier (2), a method of fabricating the storage tank, and a method of preventing hydrogen from diffusing out of a storage tank are also disclosed.
