A sustainable, low cost process for converting excess carbon dioxide (CO2) into valuable products, as an alternative to releasing it into the atmosphere, could deliver major economic and environmental benefits. Researchers at The University of Queensland are developing a bioproduction platform using electrochemically active bacteria. With a modest input of electricity (e.g. from renewable sources), the process could convert CO2 into a range of biofuels (such as butanol) and other value-added chemicals. This technology can operate effectively at small and large scales and has the potential to provide an inexpensive, environmentally friendly source of bio-chemicals. The CO2 can be gaseous or dissolved in liquid, making it suitable for use with coal seam gas water, which is high in carbonates and an ideal input to the system.
