Description:
We strongly disagree with the statement made by Realff and Eisenberger (1) that the approach we used in our analysis of the energy requirements and of “air capture” systems is circular (2). On the contrary, our analysis is linear:i) We calculated the minimum work based on fundamental thermodynamics.ii) We then estimated second-law efficiencies using a large amount of empirical data from real processes.iii) We estimated the energy costs based on market prices.The statement by Realff and Eisenberger (1) that “the notion of minimum work does not apply” is wrong. By definition, all air capture processes start with ambient air and...
