The global energy transition towards cleaner and more sustainable energy sources is imperative due to the challenges posed by the continued use of fossil fuels. Hydrogen has emerged as a critical player in this transition, especially in hard-to-abate sectors like heavy industry and long-haul transport. Its clean fuel properties make it an attractive option for mitigating climate change impacts. However, the majority of current hydrogen production comes from non-renewable sources, highlighting the need for a shift towards sustainable production methods. Various hydrogen production technologies, classified into different categories, are being developed to address specific technical, economic, and environmental requirements. Global hydrogen demand is significant, with traditional industrial sectors being the major consumers, showcasing the entrenched role of hydrogen in these applications. Despite a rise in hydrogen adoption for new applications, there is a considerable gap between current demand levels and those required for a Net Zero Emissions by 2050 Scenario. Achieving this scenario would necessitate a substantial increase in hydrogen use, especially from low-emission sources, indicating the growing importance of hydrogen in the global energy landscape.
