The urgency of hydrogen: environmental issues and the need for change

While hydrogen adoption is progressing in different industries, challenges remain. The availability of a well-developed hydrogen infrastructure, including production, storage, and distribution, is a prerequisite for broader adoption. Additionally, cost reduction through technological advancements and economies of scale is essential to make hydrogen competitive with existing energy sources. Collaborative efforts between industry, governments, and research institutions are necessary to address these challenges. Hydrogen has the potential to play a significant role in achieving decarbonization goals and transitioning to a sustainable energy future. By completely changing to a hydrogen model, the rise in global temperatures would start to revert to a normal stage after multiple years. In light of these considerations, this article aims to comprehensively review the imperative need to transition to hydrogen fuel as a pivotal component of our sustainable energy future. Furthermore, it seeks to scrutinize and dissect the unique challenges that different regions across the globe face in embracing hydrogen as a clean energy solution. By shedding light on these challenges and emphasizing the collaborative efforts required between industry, governments, and research institutions, this article aims to contribute to the discourse on harnessing hydrogen's potential to combat climate change and steer us toward a more sustainable and decarbonized future.
