Project overview

The research is to demonstrate that the in situ injection of exogenous hydrogen and carbon dioxide into a conventional anaerobic digester can substantially increase the volumetric biomethane production, and to explore the limits of this addition.
Supported by the industrial partner CJC Labs, this project investigates the extent to which the reductive transformation of CO2 to methane using renewable hydrogen can be done without interfering with the normal operation of the digester in its role as a means of stabilising organic wastes. The improved knowledge and understanding this brings can be used to develop better control systems that allow stable operation under high loading conditions.

Research interests

  • Anaerobic digestion (AD) for organic waste management and renewable energy production, especially optimisation of digestion process e.g. via selective trace element supplementation, and manipulation of microbially-mediated pathways methanogenesis
  • Mixed-culture fermentation for bio-based chemical production with integration of downstream recovery processes, especially on selective carboxylic acid production from protein-rich wastes
  • CO2 biomethanisation, especially in-situ hydrogen addition new project to be created
