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.

D4.3 Final concept description and preliminary consideration by regions.

The objective of the WP4 is to provide and analyse available information on the optimum development concept applicable to the proposed pilots of the Paris Basin (FR), the Lusitanian Basin (PT), and the Ebro Basin (ES) to go ahead with the decision of whether these pilots are viable technically and commercially, considering social and environmental demands, and in the existing European and local regulatory frame.

As it is described in D4.1 Methodology for alternatives definition, prioritisation, and selection; D4.2 Conceptual scenarios definition to enable decision support, and D4.9 Economic evaluation of alternatives and prioritisation results, each region has defined selected scenarios, reviewed them, and carried out a techno-economic evaluation, selecting the optimum development scenario for each region, i.e., Paris Basin, Lusitania Basin, and Ebro Basin; and, more general approach for Silesia Basin and Macedonia Basin. Those selected developments will be optimized during next months, being the
basis for the final investment decision report.

This deliverable describes from a technical point of view the selected scenario for each region as a
starting point for the next phase of project definition.

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.

D4.9 Economic evaluation of alternatives and prioritisation results

Based on this work package previous reports (D4.1 Methodology for alternatives definition, prioritisation, and selection; and D4.2 Conceptual scenarios definition to enable decision support), each region has defined (elements, activities, and schedule) selected scenarios, reviewed them, and carried out a techno-economic evaluation with the goal of comparing region alternatives and selecting the optimum development scenario for Paris Basin, for Lusitania Basin, and for Ebro Basin; and, with lower detail but following the same approach, for Silesia Basin and Macedonia Basin. Those optimum developments will be built and evaluated in detail by each region team during next months, being the basis for the final investment decision report.

Every region developed and evaluated their region scenarios framed by its own objectives, using a fit for purpose approach: while the French team was focused on a pilot (pre-commercial) development, the Portuguese and Spanish teams have considered, in addition, a possible commercial development. Polish and Greek cases show a more general study for the full-life case. Therefore, the different regions development and timeframe are diverse from the very beginning, compiling a cluster of examples for possible applications in the future.
