摘要:
The invention relates to an industrial unit for production of hydrogen for commercial resale or re-use including the generation of electricity. The unit is able to consume the entire output from already existing electric power plants (1), and more specifically the power, which is not consumed by the grid during off-peak periods of the day. This is managed by a device (3) for control and commutation of the electrodes within the electrolyser (4). Such systems are useful for nuclear and other power plants that produce electricity continuously. The primary concern with this solution is the safe storage of the significant volume of hydrogen that can be produced. We believe our system solves this problem effectively. The hydrogen (7) produced through electrolysis is stored in a cylindrical tank (11) which bottom part accommodates a movable floating plunger with a sealing ring (12). The plunger stroke (12) is stopped in its lower part by a limit ring (13), while the industrial tank (11) is arranged in a deep pit (14) flooded with water (15). Below the plunger (11), there is a layer of floating lubrication oil (16). The hydrogen (7) produced by the unit is fed to a bottling and/or liquefaction warehouse (17) and to a thermal-electric power plant cogenerating electricity (18). Two modifications of the system relate to self-dependent plants for production of hydrogen located on floating platforms (one of them uses a solar power plant, and the other uses water turbines submerged in the region of an ocean drift).

Substantially rectangular-shaped tanks are provided for storing liquefied gas, which tanks are especially adapted for use on land or in combination with bottom-supported offshore structure such as gravity-based structures (GBS). A tank according to this invention is capable of storing fluids at substantially atmospheric pressure and has a plate cover adapted to contain fluids and to transfer local loads caused by contact of said plate cover with said contained fluids to an internal frame structure comprised of a plate girder ring frame structure and/or an internal truss frame structure. Optionally, a grillage of stiffeners and stringers may be disposed on the plate cover and additional sifters disposed on the plate girder ring frame structure and/or an internal truss frame structure. Methods of constructing these tanks are also provided.
