This research investigates the potential of green hydrogen as a game-changing element in achieving a cleaner and more sustainable energy landscape. It focuses on modern technological approaches that enable the efficient generation, storage, and application of green hydrogen in replacing conventional fossil-based energy systems. Notably, recent improvements in electrolyser technologies such as Proton Exchange Membranes (PEM) and Solid Oxide Electrolysers have enhanced the practicality and cost- effectiveness of green hydrogen production. Companies such as Siemens Energy and ITM Power are at the forefront of these developments, offering scalable industrial solutions. In addition, hydrogen fuel cells are gaining traction in the transport sector, notably in fuel cell-powered electric vehicles and long-haul logistics. Another key innovation is the incorporation of green hydrogen into traditionally carbon- intensive sectors like steel production, ammonia synthesis, and power generation. It also has applications in blending with natural gas and serving as a medium for seasonal energy storage, helping to balance supply variability in renewable power grids. This study also discusses methods for safely storing and transporting hydrogen, including its conversion into liquid carriers or ammonia for international energy trade. The research assesses green hydrogen’s capability as a flexible and zero-emission energy vector with immense promise to cut global carbon emissions. Despite existing barriers such as production costs and infrastructure limitations, numerous pilot programs and governmental strategies demonstrate a growing global commitment to this technology. There is ongoing potential to improve efficiency, reduce costs, and develop comprehensive policies that will make green hydrogen a key pillar in the global clean energy transition.
