Abstract

The invention relates to a high-efficiency hydrogen production system suitable for wide power fluctuation. The high-efficiency hydrogen production system comprises a power supply device, a power supply module, a power prediction module and at least one electrolytic hydrogen production module, the electrolytic hydrogen production module comprises an alkaline electrolytic cell module, a pure water electrolytic cell module and an SOEC electrolysis module which are designed in parallel; through the combined electrolytic hydrogen production configuration of the alkaline electrolytic cell module, the pure water electrolytic cell module and the SOEC electrolytic module, large-range adjustment of power is realized, and the electrolytic cell module is automatically started / stopped according to the power of a wind / photoelectric device which is predicted and input by the power prediction module. It is ensured that the electrolytic hydrogen production module keeps working under the good energy conversion efficiency, the adaptability of the hydrogen production system to wind / light electricity is further improved, and the power fluctuation of the hydrogen production system is effectively coped with; and meanwhile, the problems of excessive heat release and high-power bearing capacity of single hydrogen production equipment with large gas yield under a low-power working condition are avoided, and the total energy utilization efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of water electrolysis hydrogen production, in particular to a high-efficiency hydrogen production system suitable for wide power fluctuation. Background technique [0002] Hydrogen energy is an ideal secondary energy source. Compared with other energy sources, hydrogen energy has a high calorific value and the combustion product is water. It is the most environmentally friendly energy source. Hydrogen energy is considered to be the ultimate energy source for human society in the future. Hydrogen energy storage technology is considered to be an effective way to solve the problem of renewable energy consumption. Through the hydrogen production process of renewable energy power generation, low-carbon hydrogen production and green hydrogen production can be effectively realized. [0003] However, due to the high energy consumption of the water electrolysis process and the volatility of wind power, photovoltaics ...
