Electrochemical water treatment-electrolysis hydrogen production combined system and method suitable for peak regulation of fluctuating power supply

Abstract

The invention provides an electrochemical water treatment-electrolysis hydrogen production combined system and method suitable for peak regulation of a fluctuating power supply. Surplus electric powerof the fluctuating power supply is simultaneously used to supply power to electrochemical water treatment and hydrogen preparation by water electrolysis, and raw water for hydrogen preparation by water electrolysis is obtained from raw water at a position where a power supply for electrochemical treatment is located, so that the adverse effect of water resource lack on hydrogen production in regions with surplus clean power supplies is solved, and high comprehensive benefits are achieved. The generated hydrogen has higher value, and green optimization and upgrading of industries in surrounding areas can be driven. Flexible peak regulation of the fluctuating power supply can be realized, stability of a power grid or local-distributed electricity utilization is improved, and supplying spaceof clean fluctuating power supplies is increased or depth of peak regulation of thermal power is increased.

Description

technical field [0001] The invention relates to a method for fluctuating power supply peak regulation, in particular to an electrochemical water treatment-electrolytic hydrogen production combined system and method suitable for fluctuating power supply peak regulation. Background technique [0002] In recent years, the installed capacity of renewable energy such as wind power and photovoltaics has developed rapidly. In the future, variable energy power generation will occupy a larger proportion of electric energy, which puts forward higher requirements for the stability and safety of electricity consumption. Through electrolytic hydrogen production, the conversion of fluctuating renewable energy or excess thermal power into hydrogen can realize large-scale and long-term peak-shaving and valley-filling of energy, which is a good method to stabilize fluctuations. However, areas such as the Three Norths, which are rich in wind and light resources in my country, often face the p...
