可再生电力电解制绿色氢能的发展现状与建议

Hydrogen energy is an important supplement to the energy needed for human survival and development. The development and utilization of hydrogen energy industry, especially hydrogen fuel cell vehicles, has attracted extensive attention all over the world. However, one of the key factors determining the rapid development of the industry is a clean source of hydrogen, which makes the hydrogen energy industry more economical and environmentally competitive. Using renewable energy to generate hydrogen by water electrolysis and storing energy in the form of chemical energy, not only can renewable energy be used to produce hydrogen with high caloric value, but also clean renewable energy can be used from the source of hydrogen production to reduce carbon emission. This paper analyzes and discusses the coupling of renewable energy power generation such as wind, light and water with water electrolysis hydrogen production technology, describes the current research progress of green hydrogen energy production projects utilizing renewable energy power generation at home and abroad, and introduces some typical clean hydrogen production cases. The paper points out that wind power and solar hydrogen production are relatively mature technologies at present, but their economic competitiveness still needs to be improved. However, the uneven distribution of hydropower resources hindered its large-scale development. Therefore, the government, enterprises and research institutes need to vigorously promote the research on hydrogen production from renewable energy power generation, effectively solve the problem of energy consumption and accelerate the development of hydrogen energy industry.
