Hydrogen, a clean and renewable energy source, is currently being researched and developed as a promising alternative to decarbonize the energy sector. It offers carbon-free fuel flexibility and energy storage for the global grid. There are various technologies for hydrogen production, including biological and photo-catalytic methods. This review paper discusses these technologies, their aspects, challenges and potential advancements. The reviewed work indicates that current biological hydrogen technologies generally have lower yields and conversion efficiencies and are only applicable to a minority of biomass materials. However, they are sustainable, environmentally friendly and operate at low temperatures. Similarly, photo-catalytic hydrogen technology is also environmentally friendly and sustainable, using natural sunlight and water to generate hydrogen with minimal greenhouse gas emissions. Nevertheless, its efficiency is still lower than other methods such as steam methane reforming and electrochemical electrolysis of water.
