A Recent Review of Primary Hydrogen Carriers, Hydrogen Production Methods, and Applications

Hydrogen is a promising energy carrier, especially for transportation, owing to its unique physical and chemical properties. Moreover, the combustion of hydrogen gas generates only pure water; thus, wide utilization can positively affect human society achieve global net zero CO2 emissions by 2050. This review summarizes characteristics primary carriers, such as water, methane, methanol, ammonia, formic acid, their corresponding production methods. Additionally, state-of-the-art studies applications in recent years are also included this review. In addition, conclusion section, we summarize advantages disadvantages carriers techniques suggest challenging tasks future research.
