- This paper presents an ongoing project with the aim to assess a CO 2 infrastructure in the Skagerrak/Kattegat region (the sea bordered by north of Denmark, south coast of Norway and the west coast of Sweden). The area comprises 10-12 CO2 emission sources of more than 0.5 Mt/year. The geological and geophysical assessment of CO2 storage potential in the described area as well as reservoir modelling and simulations are performed in work package (WP) 1. The results from WP1 are used in the other work packages. Candidate storage sites are matched with those point sources in the region that are technically and economically feasible for CO2 capture, together with an assessment of the connecting infrastructure needs. WP 2 focuses on identifying optimal technological CO2 infrastructure solutions. Sources-to-sink solutions are in the process of being developed based on input from WP1 and WP3. Assessment of the build-up of a complete CCS infrastructure from a system perspective is the overall focus of WP 3, covering economical, practical and judicial aspects. The project group explores the economic potential for capture at each individual site including looking at other CO2 mitigation options and propose relevant capture technology with cost estimations. Dissemination of project results is organized in a separate work package, WP4.

- Two absorbents, ammonia and MEA, have been evaluated for post-combustion capture of carbon dioxide at an aluminum manufacturing plant with respect to technical and economic performance. Process simulations combined with advanced thermodynamic models are used to model the process performance. A detailed economical estimation has been made for both ammonia and MEA-based post combustion capture as a function of flue gas CO2 concentration. The two processes have been compared with respect to the specific capture cost (€/tCO2 captured). The results show that the ammonia-based process is the most cost efficient at high flue gas CO2 concentrations (7-10%) with a cost of 74-82 €/tCO2 and the MEA-based process is the most cost efficient option at low flue gas CO2 concentrations (3-4%) with a cost of 93-97 €/tCO2. A heat integration analysis reveals that up to 50% of the heat requirement can be covered with excess heat from the aluminum manufacturing plant, which potentially could reduce the capture cost with 10-15 €/tCO2.
