Cost analysis of air capture driven by wind energy under different scenarios

Reducing the concentration of carbon dioxide(CO) in the air can effectively alleviate climate change.Air capture,which captures COdirectly from the air in an industrial process,is an alternative option to address climate change.The results of recent studies on the energy demand in COcapture process and the costs of COtransport and COstorage in air capture are analyzed in this paper.Considering renewable energy will not produce additional COin the process of utilization,the electric energy in COcapture process of air capture driven by wind energy is different from that of carbon capture and storage.Taking externalities of renewable energy intoaccount,the trading price of COemission is taken to assess the cost of electric energy in COcapture of air capture driven by wind energy.Finally,the total cost and the total cost savings of air capture driven by wind energy under different scenarios are analyzed.
