海上风电制氢技术及氢能产业发展现状与建议OA

The utilization of offshore wind power for hydrogen production is an important way to achieve the emission peak and carbon neutrality goal in the future.This paper introduces the advantages and disadvantages of different water electrolysis hydrogen production technologies,as well as the operation modes of offshore wind power hydrogen production equipment.It analyzes the development status of the hydrogen energy industry from three aspects:hydrogen storage and transportation,hydrogen refueling stations,and hydrogen energy application fields,and puts forward suggestions for the development of hydrogen energy industry.The research results show that:1)The overall cost of alkaline water electrolysis hydrogen production equipment is low,and the hydrogen production of single equipmont is large,but it is difficult to quickly start and adjust the load.It is suitable for centralized wind power supply with small output power fluctuations.2)PEM water electrolysis hydrogen production equipment can better couple outpwt power supply with large fluctuations.In the future,such hydrogen production equipment will develop towards high-power and low-cost hydrogen production to meet the needs of large-scale offshore wind power hydrogen production projects.3)In the short term,high-pressure gaseous hydrogen storage technology is the focus of development;In the long run,low-temperature liquid hydrogen storage technology is an important direction for future development.The development of new compound hydrogen storage technologies such as ammonia hydrogen storage,methanol hydrogen storage,and organic liquid hydrogen storage provides more options for hydrogen energy storage.4)At present,hydrogen refueling stations with a daily refueling capacity of 200 kg in China are demonstration operation stations.In the future,hydrogen refueling stations are expected to start with a daily refueling capacity of 500 kg,and hydrogen refueling stations with large daily refueling capacities will become mainstream stations to be built within the next one to two years.
