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.
