As one of the important green energy development directions to achieve the goal of carbon peak and carbon neutralization, the domestic hydrogen energy development heat is rising day by day. Statistics show that at present, more than 20 provinces and 40 prefecture level cities in China have issued hydrogen energy plans, with a planned industrial scale of more than trillion yuan; Many central enterprises and listed companies are also competing to layout hydrogen energy development. At the same time, as an emerging industry, hydrogen energy faces problems such as lack of core technology and high cost in manufacturing, storage, transportation and processing, immature standard system, imperfect industrial chain and supporting facilities, which need to be solved from the aspects of improving policies, clarifying standards, breaking through key core technologies and independent innovation and R & D of important equipment and materials, and guiding capital investment.
