The document argues that carbon capture and storage (CCS) is a cost-effective solution for Portugal to reach carbon neutrality by 2045, particularly for hard-to-abate industries like cement and pulp and paper. It highlights a theoretical geological storage capacity of 7.09 GtCO2 and proposes the development of industrial clusters, specifically in the Lusitanian Basin, to scale the technology.

Portugal has a theoretical CO2 storage capacity of 7.09 GtCO2, which could support the decarbonisation of its energy-intensive industries, particularly cement and pulp and paper. While no active CCS projects exist, the STRATEGY CCUS project has identified the Lusitanian Basin as a key area for cluster development. To accelerate adoption, the document recommends creating a national carbon management strategy, clarifying offshore maritime space permits, and establishing cross-border storage partnerships with EU member states like Spain.
