Biohydrogen – Clean Energy Potential

Biohydrogen production is emerging as a highly promising pathway for generating clean, carbon-neutral hydrogen using biological and thermochemical processes. Techniques such as dark fermentation, photofermentation, microbial electrolysis, and biomass gasification enable hydrogen generation from renewable organic materials. Ongoing research focuses on improving hydrogen yield, microbial efficiency, and reactor stability through metabolic engineering, catalyst development, and process optimization. Biohydrogen offers significant environmental benefits, including minimal greenhouse gas emissions and the ability to utilize agricultural residues, wastewater, and algal biomass as feedstocks. Advanced purification methods ensure high hydrogen purity suitable for fuel cells, transportation, and industrial applications. Integration with biorefineries enhances system efficiency by co-producing hydrogen alongside valuable bio-based products. As global industries seek alternative fuels to decarbonize hard-to-abate sectors, biohydrogen stands out as a scalable, sustainable solution that aligns with future hydrogen economies and long-term climate goals.
