This study of hydrogen fuel cellsHydrogen fuel cells investigates their appeal as a sustainable energy technology. It looks at how they are made, stored, and used and their environmental impact. A detailed assessment of a wide range of hydrogen technologies, including steam methane reforming (SMR)Steam Methane Reforming (SMR), electrolysis, biomass gasification, and advanced processes such as photocatalytic and photobiological water splitting. Liquidity Storage issues were assessed for compressed gas, cryogenic liquid, metal hydrides, and carbon-based nanomaterials. The study shows that SMRSteam Methane Reforming (SMR) may be the most common way of getting hydrogen, but it gives off a lot of carbon, so it needs cleaner ways like using renewable energy to power electrolysis. Innovative technologies like carbon captureCarbon capture, solid oxide electrolyzers, and nuclear-assisted hydrogen production improve output and trim carbon emissions. Storing hydrogen poses a technical challenge. Different storage methods come with trade-offs in energy density, cost, and safety. Hydrogen fuel cellsHydrogen fuel cells are utilized in transportation, industrial processes, energy generation, and aviation. Nonetheless, there are still problems like infrastructure and cost. A study of the hydrogen market shows an across-the-board increase in investment, incentives from governments, and the development of storage and distribution networks. According to the study, hydrogen fuel cellsHydrogen fuel cells can help the world to decarbonize. However, continued refinement, reduced cost, and expansion of infrastructure are required for mass adoption. Overcoming such obstacles will be essential if we want hydrogen to be a scalable and efficient energy carrier for a low-carbon future.
