- Application of advanced technologies for CO2 capture from industrial sourcesPublication . Romano, Matteo C.; Anantharaman, Rahul; Arasto, Antti; Ozcan, Dursun Can; Ahn, Hyungwoong; Dijkstra, Jan Wilco; Carbo, Michiel; Boavida, DulceThe great majority of the research on CO2 capture worldwide is today devoted to the integration of new technologies in power plants, which are responsible for about 80% of the worldwide CO2 emission from large stationary sources. The remaining 20% are emitted from industrial sources, mainly cement production plants (~7% of the total emission), refineries (~6%) and iron and steel industry (~5%). Despite their lower overall contribution, the CO2 concentration in flue gas and the average emission per source can be higher than in power plants. Therefore, application of CO2 capture processes on these sources can be more effective and can lead to competitive cost of the CO2 avoided with respect to power plants. Furthermore, industrial CO2 capture could be an important early-opportunity application, or a facilitate demonstration of capture technology at a relative small scale or in a side stream. This paper results from a collaborative activity carried out within the Joint Programme on Carbon Capture and Storage of the European Energy Research Alliance (EERA CCS-JP) and aims at investigating the potentiality of new CO2 technologies in the application on the major industrial emitters.
- CCS infrastructure development scenarios for the integrated Iberian Peninsula and Morocco energy systemPublication . Kanudia, Amit; Berghout, Niels; Boavida, Dulce; Van den Broek, Machteld; Cabal, Helena; Carneiro, Júlio; Fortes, Patricia; Gargiulo, Maurizio; Gouveia, João Pedro; Labriet, Maryse; Lechón, Yolanda; Martinez, Roberto; Mesquita, Paulo; Rimi, Abdelkrim; Seixas, Júlia; Tosato, GianCarloThis 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.

- Planning CCS development in the West MediterraneanPublication . Boavida, Dulce; Carneiro, Júlio; Martinez, Roberto; Van den Broek, Machteld; Ramirez, Andrea; Rimi, Abdelkrim; Tosato, GianCarlo; Gastine, MarieTransport and storage of CO2 are the elements in the CCS chain with the lowest cost, but they may well prove to be the elements defining the timeline for CCS development. The EU FP7 COMET project aimed to pave the road towards CCS development in the West Mediterranean (Portugal, Spain and Morocco). This paper provides the main highlights of the work conducted within COMET. The project addressed the temporal and spatial aspects of the development of the energy sector and other industrial activities in relation with CCS and its participation to CO2 emission reduction taking into account location, capacity and availability of CO2 sources and of potential CO2 storage formations. Special attention was given to a balanced optimization on transport modes, matching the sources and sinks, meeting optimal cost-benefit trade-offs, for a CCS network infrastructure as part of an international cooperation policy.
- Region specific challenges of a CO2 pipeline infrastructure in the West Mediterranean area. Model results versus stakeholder viewsPublication . 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, GianCarloThis 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.
- Storage capacity evaluation for development of CO2 infrastructure in the west MediterraneanPublication . Martinez, Roberto; Suárez, Isabel; Carneiro, Júlio; Zarhloule, Yassine; Le Nindre, Yves-Michel; Boavida, Dulce“Integrated infrastructure for CO2 transport and storage in the West Mediterranean”,known by the acronym COMET is an FP7 project, funded by the European Commssion. COMET Work Package 3 aims to identify and to evaluate geological structures and formations that have a potential to host CO2 captured from industrial plants. Although these structures can be just defined through their location, geometry and capacity, there are many other factors that will have an influence in the behaviour of the storage, such as injectivity, salinity, sealing rocks, etc. Many of these factors are studied within COMET and their values are included in generated databases. Moreover, COMET Project also aims to evaluate different scenarios of CO2 sources and sinks in the West Mediterranean region, in order to propose most effective settings for CO2 transport and storage networks. The goal of COMET is to use all available geological parameters in order to obtain a qualitative qualification of the storage sites. This qualification will be useful for network modellers who will use it as a tool to decide where most effective solutions can be found for linking CO2 sources and sinks. Moreover, once storage sites are identified, evaluated and ranked, a quantification of the potential storage costs has been carried out. These costs are used as a first approach to much more detailed models that are under development in other Work Packages.
