DAC operational costs, and thus deployment potential, is dependent on performance, which can vary under different climate conditions. Here, to further develop the understanding of the impact of regional climate variation on DAC performance, the authors use high-resolution hourly based global weather profiles between 2016 and 2020 and weighted average capital costs to obtain DAC regional performance and levelized cost of DAC (LCOD). The authors found that relatively cold and drier regions have favorable DAC performance. Moreover, approximately 25% of the world’s land is potentially unsuitable due to very cold ambient temperatures for a substantial part of the year.
