We develop power-to-gas technology based on gas fermentation by the use of active microorganisms – or active microbial communities – as biological catalysts. By using knowledge on gas mass transfer, systems engineering and microbial physiology, we engineer these complex systems to catalyze the desired process.

Our primary workhorse(s) is the methanogens, a group of Archaea, that catalyze the formation of methane. We study both the methanogenic communities that can utilize hydrogen (H₂) as electron carrier, as well as methanogens that can utilize electrons directly from a cathodic surface in bioelectrochemical cells. 

Although our primary focus is biomethation, catalyzing the conversion of electricity to carbon-based fuels, we also work within a range of different areas and projects within bioengineering and industrial microbiology, including anaerobic digestion, wastewater treatment and air cleaning.
