Renewable Hydrogen Fuel from Photofermentation of Glycerol: Enhanced Reviews

The fluctuating fossil fuel price in the global energy sector and environmental destruction that comes with such fuels have paved ways for alternative fuels. Renewable hydrogen fuel is one of those alternatives which have generated massive interest in the world of renewable energy due to its unique property as a fuel-free of any pollutant. Biochemical conversion of waste materials of biomass origin to hydrogen is a sustainable technique for hydrogen production. Glycerol, a waste obtained during biodiesel manufacturing process has been found to be a suitable feedstock for hydrogen production using PF processes. The present work reviewed literature related to the PF process of glycerol to hydrogen. In the process, a methodical comparative study of recently available research reports on renewable hydrogen production as fuel from glycerol through PF was employed. The review emphasizes the challenges bedeviling PF of hydrogen from glycerol and suggested solutions to that effect with future recommendations on potential research areas needed to be undertaken to improve the process.
