Fueling the future: A comprehensive review of hydrogen energy systems and their challenges

This comprehensive study assesses the current state of the hydrogen energy system and investigates its potential to transform the global energy landscape while addressing important concerns about climate change. While hydrogen energy has numerous advan-tages, including sustainability and cleanliness, it faces substantial challenges in the areas of storage, manufacturing, distribution, infrastructure, safety, and cost. Scholars, law-makers, business leaders, and the general public must all work together to address these complex issues. The research emphasizes the significance of breakthrough technology and astute government policies for the successful development and widespread deployment of hydrogen energy systems. It highlights that this revolutionary effort cannot be performed in solitude. Public education and enhanced awareness appear to be significant factors in promoting greater acceptance and use of hydrogen energy. Furthermore, the study iden-tifies critical future research objectives. It underlines the importance of enhancing the efficiency, sustainability, safety, and economic feasibility of hydrogen energy systems. The development of new storage systems, superior infrastructure designs, and seamless inte-gration technologies is vital to achieving the full potential of hydrogen energy. Finally, the research presented here gives a critical assessment of the hydrogen energy situation and outlines a roadmap toward a more sustainable and resilient future. The review's conclu-sions are significant for policymakers, academics, and stakeholders because they provide critical insights into the opportunities and problems associated with realizing the full potential of hydrogen energy.
