Water electrolysis hydrogen production system

Abstract

The invention relates to the technical field of clean energy and water electrolysis hydrogen production, in particular to a water electrolysis hydrogen production system, which comprises a hydroelectric generation system, an electric power storage system, a water electrolysis hydrogen production system, a hydrogen purification system and a hydrogen storage system, wherein the lower side of the hydroelectric generation system is provided with the electric power storage system; the water electrolysis hydrogen production system is arranged on one side of the hydroelectric generation system, the hydrogen purification system is arranged at one end of the water electrolysis hydrogen production system, and the hydrogen storage system is arranged at one end of the hydrogen purification system. Inthe invention, by arranging the hydroelectric generation system, the hydrogen storage system, the water electrolysis hydrogen production system and the hydrogen purification system, waste water is used for power generation, energy waste is avoided, the electricity price is low, on-site hydrogen production is achieved, and energy storage is facilitated.

Description

technical field [0001] The invention relates to the technical field of clean energy technology and water electrolysis hydrogen production, in particular to a hydroelectric electrolysis water hydrogen production system. Background technique [0002] With the increasing severity of global warming and related environmental problems, the development of renewable energy sources is becoming more and more important. Renewable energy sources, such as wind, solar and hydropower, are transient in nature and require proper energy management and storage, according to According to the data released by the National Energy Administration, water abandonment is serious in Southwest China. Only Yunnan and Sichuan provinces abandoned 40 billion kWh of water last year, and the electricity price of hydropower is much lower than that of wind power and photovoltaic power. Hydrogen is a more suitable storage medium than other fuels. Energy medium, because of the high calorific value of hydrogen, th...

Problems solved by technology

Now the main solution to abandoning water is to generate electricity mainly through motors, and transmit electricity to all parts of the country through UHV transmission lines. As an energy storage medium, hydrogen can be used in hydrogen refueling stations and hydrogen compressed natural gas in the future, and its hydrogen production The rate is 100-3000nm 3 / h, for these applications, bottled hydrogen and reformed hydrogen are not applicable, water electrolysis uses waste water renewable energy to generate hydrogen on site, does not require transportation, can ensure efficient use of hydrogen, and in the future, hydrogen will be used as a kind of energy storage The medium will be more widely used. At present, the utilization of abandoned water in our country needs to be solved urgently, and the abandoned water can only be solved on the spot near the water source, which undoubtedly increases the difficulty of water energy utilization.
