Readily available thermoelectric generators operating under modest temperature differences can power CO2 conversion, according to a proof-of-concept study by chemists at the University of British Columbia (UBC).
The findings open up the intriguing possibility that the temperature differentials encountered in an array of environments—from a typical geothermal installation on Earth to the cold, desolate surface of Mars—could power the conversion of CO2 into a range of useful fuels and chemicals.
“The environment on Mars really got me interested in the long-term potential of this technology combination,” says Dr. Abhishek Soni, postdoctoral research fellow at UBC Chemistry and first author of the paper published in Device.“This is a harsh environment where large temperature differences could be leveraged to not only generate power with thermoelectric generators, but to convert the abundant CO2 in Mars’ atmosphere into useful products that could supply a colony.”
