In recent years, global warming has been an ongoing concern for experts, and the cause of this problem is the over-reliance on fossil fuels, so finding a new source of energy that can replace traditional fossil fuels is essential at this stage. In terms of hydrogen production, solar hydrolysis is a promising method for converting sunlight into renewable, sustainable, and green hydrogen energy. The most representative pathway for converting solar radiation into molecular hydrogen is photovoltaic chemistry (PEC). In terms of hydrogen storage, researchers have identified the potential of a new type of hydrogen storage vessel, the "hybrid hydrogen storage vessel," which combines an aluminum-carbon fiber reinforced plastic (Al-CFRP) composite vessel with a hydrogen storage alloy. An evaluation of this system has shown that the hybrid hydrogen storage vessel has advantages over conventional hydrogen storage technologies in terms of volume and weight of stored hydrogen. In terms of hydrogen applications, hydrogen-fueled electric powertrains offer a solution for long-distance driving using clean energy, whereas battery-powered vehicles are plagued by range limitations, which is a shortcoming in hydrogen applications. This paper critically examines the potential of hydrogen as a sustainable energy source and presents three aspects of hydrogen technology, respectively its production, storage and application. This essay highlights the importance of chemical engineering principles in optimizing the production, storage and utilization of hydrogen energy for a clean, sustainable energy future.
