Hydrogen Production from Renewable Energy: Current Status, Prospects and Challenges

Hydrogen production from renewable energy is the most important source of green hydrogen, and the active development of hydrogen production from renewable energy is of great significance to enhance the diversity, flexibility and stability of energy system. In the current carbon neutral action sweeping the world, many countries and regions, including China, have incorporated the development of hydrogen energy into their national energy transition strategies. This paper introduces the hydrogen energy strategies of major countries in the world, the current industrial development status of hydrogen production from renewable energy, the technical development trend and its economics, and analyzes the main challenges facing the development of renewable energy-to-hydrogen technology in China at the present stage (pilot demonstration stage). Finally, it is suggested that each region should promote the pilot projects of hydrogen production from renewable energy according to local conditions, and scientifically lay out the hydrogen transmission pipeline network, in order to actively expand the diversified applications of hydrogen energy. The development of the renewable energy hydrogen industry can be supported through various measures such as price, subsidies and green finance, thus helping the country to achieve the goals of peak carbon emissions and carbon neutrality.
