Once available, existing oil and gas infrastructure may be 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. Re-use of some of the existing 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. Previously published criteria for evaluation of re-use of offshore oil and gas infrastructure in a CO2 transport and storage infrastructure has been applied to infrastructure in the northern part of the Norwegian North Sea. The suggested ordering of the criteria given in Grimstad et al. (2019) has been used to assess re-use options for a cluster of potential CO2 storage sites in the Horda Platform area, near the Troll Gas Field. After application of the first criterion — location of infrastructure relative to location of CO2 storage possibilities — a short list of infrastructure that in an ideal situation be re-used remains. These are indicated in the figure below, together with petroleum fields in the northern part of the Norwegian North Sea, and the approximate location of CO2 storage possibilities. The northern part of the Norwegian North Sea, with petroleum fields and indicated potential CO2 storage sites. Infrastructure that is located in such a way that it could be re-used in a CO2 transport and storage infrastructure for the indicated storage sites are also shown. The next criterion in the re-use evaluation — availability in time — will, however, rule out all the infrastructure components identified in the application of the first criterion. Major hydrocarbon fields using the infrastructure will be in production until after 2030, some probably until after 2040. This makes re-use of the infrastructure components in the development of a CO2 storage hub in the area before this date unfeasible. New installations will be necessary, at least for the initial development of a CO2 storage hub in this area of the Norwegian Continental Shelf.

Once available, existing oil and gas infrastructure may be 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. Re-use of some of the existing 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. The ALIGN-CCUS project has, in Deliverable 3.3.5 (Grimstad et al., 2019), reviewed previously suggested criteria for re-use assessment. Preliminary results from application of these criteria, using accessible data sources in Norway, UK and the Netherlands showed that application of the suggested criteria depends on the accessibility to data sources, which are different in each country and are therefore accordingly more or less effective in screening of suitability for re-use (Grimstad et al., 2019). Grimstad et al. (2019) presented a ranking of the criteria based on their application to offshore infrastructure, based on the readiness of access to data and effectiveness for screening, in the three North Sea countries. A methodology for evaluation of re-use by CCUS projects was proposed for regional screening of re-use possibilities in the North Sea region. The table below (Table 1), reproduced from the ALIGN-CCUS D3.3.5 report, summarises the technical criteria in the proposed order of application. The level of detailed information required for the assessment is indicated, given the use of either public data sources or detailed information from the owner/operator of the infrastructure. Table 1.
