    This paper briefly illustrates a method to represent national energy systems and the geographical details of CCS infrastructures in the same technical-economic model. In the MARKAL-TIMES modeling framework a model of Morocco, Portugal and Spain with both spatial and temporal details has been implemented. As a function of assumptions on the development to 2050 of mitigation levels, economic growth and CO2 capture-transport storage characteristics, dozens of scenarios were prepared with the TIMES-COMET model. A few results on optimal levels of CCS contribution to mitigation compared to other energy system options are presented. The results also indicate the least cost lay out of the main capture, transport and storage infrastructures. It is concluded that the availability of CCS after 2020 will reduce the cost of mitigation in the Iberian Peninsula as soon as the EU GHG emissions reduction targets become more stringent than decided so far.

  • Region specific challenges of a CO2 pipeline infrastructure in the West Mediterranean area. Model results versus stakeholder views 
    Publication . Van den Broek, Machteld; Mesquita, Paulo; Carneiro, Júlio; Silva, José Rafael; Berghout, Niels; Ramirez, Andrea; Gouveia, João Pedro; Seixas, Júlia; Cabal, Helena; Martinez, Roberto; Rimi, Abdelkrim; Zarhloule, Yassine; Sardinha, Mariana; Boavida, Dulce; Tosato, GianCarlo
    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.
