Comparison of cost shares of liquid solvent, solid sorbent, and CaO ambient weathering DACCS, using tracking solar PV and storage (battery for 12 h), as well as natural gas as energy sources. The bars represent cost of CO2net removed, including the cost share of capital and fixed operating expenses (CAPEX + fixed OPEX) and variable operating expenses (OPEX), and their combined absolute values shown atop each bar. The bars differentiate costs across increasing cumulative capacity and between energy cost projections for 2022 and 2050.
