Description

technical field [0001] The invention belongs to the field of comprehensive utilization of solar energy and hydrogen energy, and relates to a floating solar photovoltaic photothermal coupling electrolysis water hydrogen production system and method. Background technique [0002] Extensive use of traditional energy such as fossil fuels has led to serious energy supply crises and environmental pollution problems, and the development of renewable and clean energy is imminent. As a new energy source, solar energy is renewable, widely distributed, widespread, and easy to obtain, but it is difficult to use directly. Solar power generation, especially solar photovoltaic power generation technology to convert solar energy into electrical energy has been practically applied, but its volatility is large, which is not conducive to integration into the grid. Hydrogen has the characteristics of high energy density, light weight, convenient storage and transportation, the combustion produ...

AI Technical Summary

Problems solved by technology

When hydrogen is produced by PEM electrolysis, the increase of electrolysis water temperature can reduce the dissipation of electric energy, thereby improving electrolysis efficiency, but increasing the temperature of electrolysis water requires additional heating devices and energy consumption

[0004] In addition, the existing solar photovoltaic water electrolysis faces the problems of large area, high cost, and obvious scale effect, which hinders the miniaturization, convenience and integration of equipment
