Second, pairing electricity driven DACS to highly intermittent renewables is not a promising strategy as the net removed cost highly depends on the plant capacity factor. Instead, grid electricity needs to be decarbonised as a priority. The performance of larger scale and predominantly natural gaspowered processes does not strongly depend on the carbon intensity of grid electricity, but the natural gas supply chains should be thoroughly reviewed to avoid the negative effects of methane leakage including an increase in net removed cost.
