WP4Pilot Development

D4.1 Methodology for alternatives definition, prioritisation, and selection

The objective of the WP4 is to provide complete information of the optimum development concept applicable to the proposed pilots of Paris Basin (FR), Lusitanian Basin (PT) and Ebro Basin (ES) to go ahead with the decision of whether this pilot is viable technically, commercially, considering social and environmental demands and in the existing European and local regulatory frame. Although each team worked independently and focus on their area particularities, it is concluded a lot of similarities between then. The most relevant is that was (still) somewhat unclear the main goal of the project: pilot or commercial development. After discussion, all now agree that the main goal is to design a carbon pilot injection storage site, and in the case of Spain and Portugal, to check the possibility of upgrade to commercial scale. Other relevant point is the need to qualitatively define the criteria for the pilot’s success.

D4.2 Conceptual scenarios definition to enable decision support

The objective of the WP4 is to provide complete information on the optimum development concept applicable to the proposed pilots. The development concept and its viability decision must be based on strategic information to identify and address existing risks and to commit available resources, maximising the potential for success. This strategic information was identified during a framing session phase conducted previously in the project and summarised in the D4.1 public deliverable “Methodology for alternatives definition, Prioritisation, and Selection,” published in May 2023, for Paris Basin, Lusitanian Basin, and Ebro Basin. In this document in also described the results for West Macedonian and Silesia regions, carried out in October 2023 and September 2023, respectively.

This report shows the different strategies outlined by every region involved in the PilotSTRATEGY projects, before a comprehensive analysis of those strategies and their associated scenarios.

D4.4 Injector well and injection facilities design: methodology, definition, and recommendations

This document serves as a high‐level guide for the design process of a CO₂ injector well and its related facilities. In general terms, the knowledge from Oil & Gas industry is applicable to CO₂ injector well but taking in mind the most notable differences: the need to ensure an ideal pressure and temperature to inject the CO₂, the casing material to avoid corrosion, and the HSE processes to monitor the progress of the CO₂ plume. This deliverable facilitates the task 4.2.1 “Different well design alternatives electing a final design based on technical, economic and HSE criteria” and partially comprises the task 4.2.3 “Capture Transport, and storage facilities outline”, including only the storage facilities section.
