Energy and Exergy Evaluation of an Integrated Dark Fermentation and Microbial Electrolysis System for Sustainable Hydrogen Production

This study evaluates hydrogen production from crude glycerol and vinasse using integrated dark fermentation and microbial electrolysis. Aspen Plus simulations showed high efficiency, with 95% COD reduction and hydrogen yields of 6.43 kg/h (fermentation) and 95.80 kg/h (electrolysis). Exergy efficiencies exceeded 81%, highlighting the system's potential for converting waste into renewable energy and supporting green hydrogen development.

Abstract

This study evaluates hydrogen production from crude glycerol and vinasse using integrated dark fermentation and microbial electrolysis. Aspen Plus simulations showed high efficiency, with 95% COD reduction and hydrogen yields of 6.43 kg/h (fermentation) and 95.80 kg/h (electrolysis). Exergy efficiencies exceeded 81%, highlighting the system's potential for converting waste into renewable energy and supporting green hydrogen development.
