“双碳”目标下绿色氢能技术发展现状与趋势研究

Hydrogen energy is a clean, zero-carbon, flexible and efficient secondary energy with abundant sources. As an important part of modern energy system, it's an important carrier to achieve the goal of carbon peaking and carbon neutralization. With the increasingly severe situation of carbon emission reduction, green hydrogen has received high attention worldwide. Hydrogen production from renewable energy can realize the whole hydrogen energy industry chain green and carbon-free, and solve the problem of renewable energy consumption, which is a very potential development route of hydrogen energy. This paper summarizes and analyzes the latest development trends of hydrogen energy industry at home and abroad, and focuses on the development status and trend of key technologies of green hydrogen energy from each link of the whole industrial chain, including hydrogen production, hydrogen storage, hydrogen transportation, hydrogen filling and application. Then based on the development situation of hydrogen energy industry in China, several typical application scenarios and development suggestions are put forward, which provides reference for the development of green hydrogen energy.
