Researchers from the University of Toronto have developed an electrochemical method of converting molecules made from captured CO2 back into a gas , eliminating the heating stage required by other methods . The team synthesized dissolved carbonate using a bipolar membrane electrolyser , which also contains a silver - zinc catalyst that converts the molecule into a syngas . They were able to convert carbonate to syngas at an overall conversion efficiency of 35 % and the molecule is said to have remained stable for more than six days of operation .
