Development Status and Outlook of Hydrogen Internal Combustion Engine

Hydrogen energy is one of the best energy carriers for achieving carbon peak and carbon neutrality, with the characteristics of high energy and no pollution. The hydrogen internal combustion engine is one of the important forms of hydrogen energy utilization, with the significant advantages of high efficiency, high reliability, low cost and low emissions. In this paper, the characteristics of hydrogen internal combustion engines and hydrogen fuel cells were compared, and the industrialization prospects of hydrogen energy utilization in the future were analyzed. Focusing on the hydrogen internal combustion engine technology system, a comprehensive analysis was conducted on the technical issues and technical progress in hydrogen storage, combustion, NOx emissions, etc. of hydrogen internal combustion engines.
