Comparative Study of Hydrogen Production from Organic Waste Fermentation and by Electrolysis to Achieve Sustainability and Decarbonization

Hydrogen has a vital role in attaining a sustainable and carbon-free future. Especially, when hydrogen is generated from renewable energy resources, hydrogen acts as an environmentally friendly source. this study compares the generation of hydrogen from the fermentation of organic wastes and water electrolysis. This study aims to collect data to help decision-makers make their decision according to effectiveness, cost-effectiveness, and sustainability. Hydrogen power has many advantages, such as sustainability and clean energy, and can be used in industry, power generation, and transportation. Reducing the carbon footprint of hydrogen production requires generating hydrogen from renewable energy resources. Fermentation of organic wastes produces hydrogen and other products during anaerobic digestion, which requires a breakdown of organic material by microorganisms in anaerobic conditions. This technique not only produces hydrogen but also aids in the management of organic wastes. On the other hand, water electrolysis is an electrochemical process that consumes electricity to split water into hydrogen and oxygen. If the source of the electricity is renewable the generated hydrogen is called green hydrogen, which is completely carbon-free.
