Current Situation and Prospect of Hydrogen Energy Industry Chain and Hydrogen Power Generation Utilization Technology
Abstract
[Introduction] With the proposal of "peak carbon dioxide emission, carbon neutrality" and the deepening of energy reform, hydrogen energy, hydrogen energy as an important industrial raw material and energy fuel has been widely concerned and entered a rapid development period. Hydrogen energy industry chain mainly includes the hydrogen preparation, storage, transportation and utilization, which involves the integration and technological innovation of many industries. This paper is aimed at sorting out the current situation of hydrogen energy industry chain and analyzing the challenge faced by each node in order to provide suggestions for the development of hydrogen energy industry in the future. [Method] In this paper, we investigated the current technical status, analyzed the problems and challenges of the hydrogen energy industry chain, and put forward the relevant suggestions. [Result] Although China has technical reserves and industrial layout in all aspects of hydrogen energy industry, many technical shortcomings need to be solved. Among them, alkaline water electrolysis technology, high-pressure hydrogen storage technology, natural gas pipeline mixing hydrogen transportation technology has preliminarily met the application conditions. However, some problems in the technologies such as low temperature liquid hydrogen technology, hydrogen manufacturing with proton exchange membrane and fuel cell technology, hydrogen manufacturing with solid oxides and fuel cell technology remain to be solved. Meanwhile, compared with international advanced level, the development of hydrogen-fueled gas turbine in China is relatively backward. [Conclusion] As a strategic energy, the utilization of hydrogen energy is very important to promote the green transformation of energy and industry. But there are still many problems. Hence, it is necessary to make a reasonable layout, avoid the repetitive construction and introduction of low-end technology to accelerate the development of hydrogen energy industry.
