HYDROGEN AND FUEL CELL

Hydrogen has emerged as a new energy vector beyond its usual role as an industrial feedstock, primarily for the production of ammonia, methanol, and petroleum refining. In addition to environmental sustainability issues, energy-scarce developed countries, such as Japan and Korea, are also facing an energy security issue. Hydrogen carriers, such as ammonia and methylcyclohexane, seem to be options to address these long-term energy availability issues. It focus on hydrogen electrification through proton-exchange membrane fuel cells (PEMFCs), which are widely believed to be commercially suitable for automotive applications, particularly for vehicles requiring minimal hydrogen infrastructure support, such as fleets of taxies, buses, and logistic vehicles. With the rapid growth of domestic renewable energy, the problems of insufficient renewable energy capacity and grid connection difficulties have become more prominent. Large-scale energy storage systems have proved to be an effective way to solve this problem. This book reviews the deficiencies and limitations of existing mature energy storage systems, analyzes the advantages and characteristics of hydrogen energy.
