Abstract:

As a secondary energy, hydrogen energy will play an important role in the future energy system dominated by renewable energy because of its green, flexible and wide-ranging characteristics. The core of large-scale development of hydrogen energy industry is to realize low-cost and efficient raw material source, storage and transportation. Therefore, a review was made on the key technologies of how to truly realize the clean and efficient utilization of hydrogen energy in the aspects of hydrogen production from renewable energy electrolyzed water and hydrogen storage and transportation. The ideas and progress were summarized in the development of hydrogen energy in Europe and Japan as the leading countries for hydrogen energy utilization, and also the cost factors of hydrogen energy were discussed. The development trend of hydrogen energy in China was analyzed, and the development prospect of China's hydrogen energy industry in the future was also put forward, the suggestions were as follows: establishing a sound legal and policy system; paying attention to the development of hydrogen supply and storage and transportation; actively exploring and developing various ways of hydrogen energy utilization.

Key words: carbon neutrality, hydrogen energy, renewable energy, water electrolysis, hydrogen storage and transportation, hydrogen-natural gas mixtures
