The quest for a carbon–neutral energy future has positioned hydrogen as a pivotal player in global-sustainability efforts. This comprehensive review examines the transformative role of hydrogen in revolutionizing sustainable energy consumption. Hydrogen’s high energy density, versatility, and minimal ecological footprint make it ideal for stabilizing the intermittent nature of renewable energy sources. This study evaluates the latest advancements in hydrogen production technologies, including advanced electrolysis, reforming strategies, and biologic processes, assessing their operational efficiencies and environmental impacts. In addition, it explores the strategic deployment of hydrogen in transportation, industrial processes, and electricity sectors, highlighting its potential to significantly reduce fossil-fuel dependence and mitigate climate change. The economic considerations and policy imperatives crucial for the global adoption and scaling of hydrogen storage systems are also discussed. This review underscores hydrogen’s critical role in creating an eco-efficient and resilient energy infrastructure, advocating for an accelerated transition to hydrogen-based solutions to achieve a cleaner, greener planet.
