Integrated multi-stage biochemical conversion technology for hydrogen based fuel cell systems

This project proposes the development of an integrated, multi-stage bioconversion technology to transform lignocellulosic organic waste (specifically fruit pomace from alcohol production, fermentation residues rich in yeast biomass etc.) into electricity through biohydrogen production and its utilization in modular hydrogen fuel cell systems. The core innovation lies in coupling microbial fermentation with electrochemical energy conversion, offering a scalable and circular solution for sustainable energy and material recovery. Lignocellulosic components from the alcohol production will serve as a substrate for hydrogen production by bacteria. Hydrogen is channeled into a modular hydrogen fuel cell system co-developed with engineers to demonstrate real-time conversion of waste-derived gas into electricity, forming a prototype microbial power unit. This allows component testing in a relevant environment, elevating the technology readiness level from TRL 3 to TRL 5. By integrating the power of microbes for biochemical conversion of the waste and the project delivers a flexible, decentralized, and environmentally friendly model for converting organic waste into electricity and renewable bio-products positioning Armenia as a regional innovator in circular bioeconomy solutions.
