Analysis on the Methods of Hydrogen Generation

The purpose of this paper is to analyze the methods of hydrogen generation. More specifically, it explains methods of several hydrogen generation, studies their existing advantages and challenges, and finally draws a conclusion of comparative advantages through analysis and comparison. In order to support this analysis, specific methods of the four categories of hydrogen generation methods proposed by the United States Department of Energy are investigated, and the essential concerns and ideas from various papers and websites were referenced and integrated to find out the advantages and disadvantages of specific hydrogen generation processes. According to the idea of sustainable development, as well as the use of hydrogen energy for clean energy replacement and renewable energy storage, it is finally considered that Solid oxide electrolytic cell (SOEC) generation hydrogen generation process is relatively the most suitable for the use of hydrogen, sustainable, and has broad future prospects. This paper can provide a detailed description of hydrogen generation and propose the future development direction of hydrogen generation.
