Objective and hypothesis
This project aims to build on the biomethanation platform as CO2 capture and integrate it with the utilisation pathways. This will be done by developing biological technologies to produce platform and value-added chemicals. The project has three objectives for this integration:

•  To develop biomethanation using Power-to-X for diverse CO2 point sources and demonstrate at TRL4.
•  To integrate acetic acid production at TRL4.
• To develop integrated fermentation of biomethane for bioplastics at TRL4.

Approach
The innovative method of the project is to integrate the promising biomethanation technology with biochemical utilisation technologies. The project will unfold in three operational work packages (WP). In WP1, work will be done to optimise the process for diverse CO2 point sources, e.g., CO2 flue gas from biomass-fired power plants. The main aim of WP2 is the design and operation of a bioreactor that can produce acetate from CO2 and H2 . WP3 is focused on developing microbial reactors for methanotrophs, understanding the metabolic limitations, and conducting lab-scale demonstrations integrated with biomethanation.

Expected impact/output
It is expected that renewable feedstock availability for fuels, chemical processes, and materials will become a limiting factor for the green transition. Capturing diverse CO2 point sources and utilising them to produce chemicals can provide a sustainable alternative. The maturation of biomethanation technology is, therefore, a crucial technology that can enable the production of value-added chemicals in the future.
