Biosolar, Utilization of CO2 by a microbial process

Project status

Project started in January 2013

The responsible director of the project is Research Professor Pertti Koukkari at VTT. The project manager is Dr. Juha-Pekka Pitkänen, VTT.

Project description

The project focuses on an exciting new technology to harness renewable bioresources for energy storage via microbial electrosynthesis (MES). In MES the solar electricity can be effectively stored to fuels and chemicals by the activity of electrically driven bacteria. Organic waste or even carbon dioxide can be used as the raw material of the MES process, giving e.g. methane, butanol or organic acids as products at the electrodes.


Microbial electrosynthesis can be expected to be more efficient than biomass-based strategies because it offers potentially much greater efficiencies in harvesting solar energy and directs energy inputs to the production of desired organic compounds rather than generating biomass.
