Regions with low relative humidity and high temperatures may experience increased costs and reduced efficiency in DAC-based methanol production. These conditions necessitate oversizing DAC units and adapting system designs, potentially limiting the feasibility of production in certain areas. However, the study confirms that DAC can provide sufficient water for methanol synthesis in most regions, mitigating risks associated with water scarcity. The technology's reliance on weather conditions underscores the need for tailored solutions in specific climates.
