Electricity-driven microbial symbiosis for the production of complex CO2-neutral chemicals

Today we are able to collect large amount of energy from renewable resources. Solar, wind and hydropower are considered viable alternatives to fossil fuels and play important roles in the transition to a more sustainable society. However, these energy sources are hampered by a discontinuous output of energy and for a larger expansion of these sustainable energies to be undertaken it is imperative that technologies for storing and transporting excess energy are developed.

Coupling renewable energy resources with CO2 as the carbon source could facilitate the decoupling of the carbon emissions from the feedstock and the energy sector. A new paradigm that can transform the future of carbon capture and chemical production is the development of a bioprocess based on electricity-driven microbial reactions for the production of CO2-neutral industrial chemicals.

This research proposal will address the development of selective biochemical routes which will transform CO2 from a liability into an asset by at the same time transforming excess renewable energy into forms which allow storage, transport or additional chemical upgrading. The use of CO2 as a feedstock, i.e. through carbon capture and utilization (CCU), has the potential to create attractive business opportunities for the production of 3rd generation biofuels.
