Through this project we develop biologically mediated upgrading systems from lab-scale to industry scale, where H2 generated through water electrolysis is biologically converted to CH4 by the action of autochthonous hydrogenotrophic methanogens.
The specific tasks in the project are:
- Standardize the design of bio-trickling filter reactors for ex-situ methanation
- Maximize the production capacity of CH4 per unit volume of the reactor
- Tests of different packing materials
- Develop SOP for the startup and operation of the bio-trickling filter reactors
- Direct inoculation with digestate from biogas plant
- Nutrient consumption and dosing strategy
- Nutrient trickling strategy
- Cooling of full-scale plants
- Recirculation of the product gas
- Design and test the operation of a 2 m3 pilot plant.
