Scientists working for the US Department of Energy have found an efficient way to turn waste carbon dioxide into fuel. The appeal of the new process is that it produces syngas, a mixture of hydrogen and carbon monoxide that can be used as a fuel – making the process more appealing to industry. The researchers used “switchable polarity solvents” – liquids that dissolve carbon dioxide at low temperatures and allowed the team to capture the carbon from it more efficiently. “This is an interesting piece of science which has discovered a much more effective method of electrolysing carbon dioxide in water,” said Professor Stuart Haszeldine, a carbon capture and storage expert at the University of Edinburgh who was not involved in the study. Though the syngas produced from this process is itself a fuel that, when used, has the potential to contribute to global warming, Professor Haszeldine said this method could still have a role in reducing fossil fuel use.
