Researchers from the University of Toronto have developed an electrochemical method of converting carbonate made from captured CO2 back into a gas, skipping the heating stage required by other methods. The team converted dissolved carbonate using a bipolar membrane electrolyser, which also contains a silver-based catalyst that converts the CO2 into a syngas. They were able to convert carbonate to syngas at an overall energy efficiency of 100% and the electrolyser is said to have remained stable for more than six days of operation.

The team converted dissolved carbonate using a bipolar membrane electrolyser, which also contains a silver-based catalyst that converts the CO2 into a syngas. They were able to convert carbonate to syngas at an overall energy efficiency of 35% and the electrolyser is said to have remained stable for more than six days of operation.
