Abstract

Hydrogen has long been recognized for its potential as a clean, versatile energy carrier. In the context of a global push towards sustainable systems and reduced carbon emissions, hydrogen stands out due to its high energy density, flammability, and environmental benefits. Despite these advantages, the production, storage, transport, and utilization of hydrogen present significant technical and economic challenges that must be addressed to realize its full potential. This paper delves into the comprehensive characteristics of hydrogen, focusing on its physical and chemical properties. It examines the various methods employed in hydrogen production, highlighting both traditional and innovative approaches, from steam methane reforming and coal gasification to biomass-derived hydrogen and water splitting, along with their respective advantages and drawbacks. Further, the paper explores key areas of hydrogen application, emphasizing its potential to revolutionize the industrial and energy sectors through hydrogen fuel cells, engines, and industrial feedstock roles. Finally, the paper addresses the current challenges in adopting hydrogen energy on a large scale, particularly the high costs and technological bottlenecks in storage and transportation. Understanding these facets is crucial for advancing hydrogen as a cornerstone of sustainable energy systems.
