Region specific challenges of a CO2 pipeline infrastructure in the West Mediterranean area. Model results versus stakeholder views

Abstract

This paper presents results of potential CCS infrastructures in the West Mediterranean region including trajectories for CO2 pipelines. The preliminary results are generated with a combination of geographical (GIS) and partial equilibrium optimization modelling (MARKAL/TIMES-COMET). Furthermore, as a result of active stakeholder involvement in the research project, the CCS infrastructures were critically reviewed and obtained insights were used to improve the models and their input parameters. Stakeholders’ feedback regarding difficulty in crossing hard rock terrains and the reasonability of trying to replicate the existing natural gas network, had a large impact on the resulting CCS infrastructure.
