Integration of thermochemical water splitting with CO2
Dec 10 2019 · Global warming as a result of rising atmospheric CO2 concentrations is considered an imminent threat to society. In order to address rising CO2 concentrations effective CO2 capture directly from the atmosphere is likely to be necessary. We integrate direct air capture CO2 and water splitting to produce a mixture of CO2 and H2 via a thermochemical water-splitting cycle.

The thermochemical oxygen production is experimentally demonstrated by applying a temperature/pressure swing between 573 K at 0.2 bar O2 and 873 K at 1 bar O2. An energy balance shows the feasibility of using process waste heat from the solar thermochemical CO2/H2O splitting cycle and the potential to compete vis-a-vis with cryogenic distillation.
