Comprehensive application system for generating electricity by natural energy and electrolyzing seawater or brackish water

Abstract

The invention discloses a comprehensive application system for generating electricity by natural energy and electrolyzing seawater or brackish water, which comprises a flow, sea wave and tide kinetic energy and wind energy and solar power generation device. Two power supply branches are divided at the electric energy output end of the power generation device, one power supply branch is directly connected with a power grid, and the other power supply branch is in circuit connection with a hydrogen energy water electrolysis generator; and the electric energy output end of the power generation device can also be only in circuit connection with the hydrogen energy water electrolysis generator and is not connected with the power grid. The hydrogen energy water electrolysis generator is used for electrolyzing pretreated seawater or brackish water to generate hydrogen and oxygen, the hydrogen output end of the water electrolysis generator is provided with a hydrogen reservoir, and the oxygen output end is provided with an oxygen reservoir. The comprehensive application system solves the problem of the storage of electricity generated by the flow, sea wave and tide kinetic energy and wind energy and solar power generation device, and also solves the problem of energy-saving desalting of the seawater or brackish water.

Description

technical field [0001] The present invention relates to the technical field of natural energy application, in particular to a comprehensive application system that uses natural energy to generate electricity and uses the generated electric energy to electrolyze seawater or brackish water to produce oxygen and hydrogen that can be used again. Background technique [0002] The applicant of the present invention once submitted an invention patent application titled "Comprehensive System of Current, Sea, Wave, Tidal Kinetic Energy and Wind and Solar Power Generation" to the State Intellectual Property Office on September 9, 2009, and its publication number is CN101649813. [0003] The power generation system can organically combine hydrodynamic energy, wind energy, and solar energy. When there is wind energy, wind power can be generated; Generating electricity with the kinetic energy of the water at the same time. The three power generation methods can complement each other and ...

Problems solved by technology

However, the power capacity of lead-acid batteries is limited, and the price is particularly expensive, and there is a problem of lead pollution when used in large quantities; nickel-metal hydride batteries and lithium-ion batteries are limited by the number of these two elements and the extremely expensive price, and cannot adopt; other energy storage methods, such as compressed air energy storage; flywheel energy storage, etc., cannot be used because of their low efficiency and small capacity.
