Document No. ALIGN-CCUS D3.3.5 Issue date 31.01.2019 Dissemination Level Public Page 3/54 Executive summary Achievement of CO2 emissions reduction targets by the industry and power sectors will require large-scale deployment of CO2 capture, transport, utilisation and storage (CCUS) (IPCC, 2018). The CO2 storage capacity in the North Sea, investigated at a regional scale and for selected individual storage sites, is predicted to be more than sufficient to meet the demand from the North Sea countries. The North Sea is a mature petroleum province and hosts an extensive network of infrastructure that will become increasingly available for re-use for CO2 transport and storage as oil and gas production declines. Once available, existing oil and gas infrastructure may be transferred or adapted to support the deployment of CO2 transport and storage networks. Re-use of infrastructure can help to reduce the cost of CO2 capture, transport and storage projects, which is critical to ensuring widespread commercialisation of these technologies to meet European and national targets for decarbonisation. Several previous studies have established that re-use of some of the existing offshore oil and gas infrastructure is technically feasible and can be cost effective. There are, however, both technical and legal challenges with re-use of existing infrastructure, and neither its suitability, nor availability can be presumed. This ALIGN-CCUS project research reviews previously suggested technical criteria for re-use assessment and presents a ranking of the criteria based on their application to offshore infrastructure in three North Sea countries. The resulting methodology for evaluation of re-use by CCUS projects is proposed for regional screening of re-use possibilities in the North Sea region. The following table summarises the technical criteria in the proposed order of application. The level of detail for the assessment is indicated, given the use of either public data sources or detailed information from the owner/operator of the infrastructure.
