The impact of climate on solvent-based direct air capture systems

•The CO2 capture rate of liquid-solvent DAC is strongly influenced by air temperature and relative humidity.•Varying CO2 capture rates have a strong impact on overall energy demand of DAC and levelized cost of CO2 removal.•Levelized cost of capture can vary by a factor of nearly two between cold, dry conditions and warm, humid conditions.•GHG intensity of energy supply is, however, more influential than climate conditions in determining efficiency of removal.•Estimates of DAC potential should consider specific climate conditions rather than relying on generic performance figures.
