Daggash, H. A.; Patzschke, C. F.; Heuberger, C. F.; Zhu, L.; Hellgardt, K.; Fennell, P. S. et al. (2018): Closing the carbon cycle to maximise climate change mitigation. Power-to-methanol vs. power-to-direct air capture. In Sustainable Energy Fuels 5 (12), p. 498. DOI: 10.1039/C8SE00061A.
„This study sets out to quantify (a) the amount of curtailed renewable energy that is likely to be available in the coming decades, (b) the amount of fossil CO2 emissions which can be avoided by using this curtailed energy to convert CO2 to methanol for use as a transport fuel – power-to-fuel, with the counterfactual of using that curtailed energy to directly remove CO2 from the atmosphere via direct air capture (DAC) and subsequent underground storage, power-to-DAC.“
