IEA Bioenergy has published an Inter-Task report onĀ Synergies of green hydrogen and biobased value chains deploymentĀ (seeĀ hereĀ for accompanying blog).Ā An associated webinar is available here.
Dr Luca Alibardi of Cranfield University, co-Lead of EBNet’s Anaerobic Fermentation WG, welcomed the report with the following comment:
āThe case study targeted a carbohydrate-rich wastewater, which is an ideal substrate to enhance biohydrogen production via dark-fermentation: but it is not the only option, as the process can also work with solid waste or biomass, with variable compositions.
It is also good to see the integration of dark fermentation with biomethane production, together with the indication of increased biomethane generation due to higher substrate conversion, thanks to a more efficient overall process.
This is one nice example of many other case studies aiming to demonstrate the potential of dark fermentation to generate carbon-neutral hydrogen and the benefit of its integration with other bioprocesses, with methanogenesis as the simplest option to implement a biorefinery chain that can extract more value from waste, wastewater or biomassā.
