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

Reducing the concentration of carbon dioxide (CO
2
) in the air can effectively alleviate climate change. Air capture, which captures CO
2
directly 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 CO
2
capture process and the costs of CO
2
transport and CO
2
storage in air capture are analyzed in this paper. Considering renewable energy will not produce additional CO
2
in the process of utilization, the electric energy in CO
2
capture process of air capture driven by wind energy is different from that of carbon capture and storage. Taking externalities of renewable energy into account, the trading price of CO
2
emission is taken to assess the cost of electric energy in CO
2
capture 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.
