Lastly, studies on integrating DAC into existing industry clusters are largely absent (#19). DACCS could benefit if integrated into already existing industrial clusters by either using waste heat, if available from other industrial processes, or delivering conditioned CO 2 to already existing CCUS infrastructure. There are several transport and storage projects currently in development, which are associated with industrial clusters (e.g., four transport and storage projects linked to five industrial clusters in the UK, the Porthos project in the Netherlands for transporting CO 2 to offshore storage sites, and the Houston CCS storage hub in the US) that DACCS could benefit from by plugging in. Although integration into existing industrial clusters appears beneficial, it may also present tradeoffs given opportunities to optimize waste heat integration within the cluster before it is dedicated to DAC operations.
