Introduction Hydrogen production by electrolysising water has been widely used in coal-fired, gas and nuclear power plants, and will also be more widely used in hydrogen energy projects supporting renewable energy power plants. It is necessary to discuss the design scheme of hydrogen production system. Method In this paper, a coal-fired power plant, wind power generation plant and solar photovoltaic power plant supporting hydrogen energy project were taken as examples. According to the design regulation of relevant standards and codes, the design scheme of the hydrogen production system was elaborated.
Result The technology of hydrogen production by alkaline electrolysising water is mature, safe and reliable, which can continuously provide hydrogen to meet the requirements of purity and humidity for hydrogen-cooled generators, hydrogen-filling stations and hydrogen users.
Conclusion This paper aims to provide a reference system design scheme of hydrogen production by electrolysising water for more power plants and hydrogen energy projects.
