From the abstract it seems to be very applicable to combustion exhausts (coal/gas plants) and consuming 5-10% of the combustion energy to recapture the CO2. Hard to tell what is the required CO2 concentration without the full article. Typical combustion exhaust seems to be ~10% of CO2, https://en.wikipedia.org/wiki/Flue_gas https://en.wikipedia.org/wiki/Flue_gas Edit: spelling.
