The University of Michigan, in collaboration with the University of Massachusetts Amherst, will develop a technology that captures CO2 from the atmosphere using an electrochemical approach, rather than the temperature swing cycle which is typically powered by fossil fuel combustion. The team’s concept is a pH swing cycle that changes conditions between basic and acidic to capture and release CO2, respectively. Direct air capture (DAC) of CO2 by inexpensive renewable electricity could reduce the cost and improve the efficiency of DAC. The team aims to optimize the design of the cycle to achieve high rates of CO2 separation at low energy inputs.
