Preem CCS - Synthesis of main project findings and insights

The Preem-CCS project was a Swedish-Norwegian collaboration that investigated CO2 capture from the Preem refineries in Sweden, and subsequent ship transport of captured CO2 for permanent storage on the Norwegian Continental Shelf. The project was conducted from early 2019 to beginning of 2022 and funding was provided by the Norwegian CLIMIT-Demo program via Gassnova, by the Swedish Energy Agency and by the participating industry and research partners (Preem, Aker Carbon Capture, SINTEF Energy Research, Chalmers University of Technology, and Equinor).This report summarizes the key findings of the project activities listed below:\ua0 -\ua0Pilot-scale testing of CO2 capture at the hydrogen production unit (HPU) at the Lysekil refinery using the Aker Carbon Capture (ACC) mobile test unit (MTU)\ua0 -\ua0In-depth investigation of energy efficiency opportunities along the CCS chain, including the use of residual heat at the Lysekil refinery site to satisfy the energy requirements for solvent regeneration\ua0 -\ua0Evaluation of the technical feasibility and cost evaluation of the CCS chain including CO2 capture and transportation by ship to storage facilities off the Norwegian west coast\ua0 -\ua0Investigation of relevant legal and regulatory aspects related to trans-border CO2 transport and storage and national emissions reduction commitments in Norway and SwedenThe report also discusses the next steps towards implementation of CCS at Preem refineries in Lysekil and Gothenburg

Potential Impact of the Preem-CCS Project

The ongoing Preem CCS project investigates opportunities for CO2 capture from the Preem refineries in Lysekil and Gothenburg, Sweden, with focus on the Lysekil refinery. The consortium members of this Norwegian-Swedish collaboration are Preem AB, Chalmers University of Technology, SINTEF Energy Research, Equinor Energy and Aker Carbon Capture. In this paper, we present the alternative carbon capture and storage (CCS) value chains that are being studied, together with the potential amounts of direct CO2 emissions from production that can be captured in each case. We also discuss potential cost reduction factors for CO2 capture at the Preem refineries, such as heat integration within the refinery and economies of scale, which may also be of relevance for reduction of capture costs for other Northern Lights partners. The implementation of CO2 capture in the Preem refineries will be an important step not only for Preem but also for Sweden to reach their climate neutrality goals

Lessons learned from the Preem-CCS project – a pioneering Swedish-Norwegian collaboration showcasing the full CCS chain

This paper presents the key findings of the Preem-CCS project, a co-funded Swedish-Norwegian R&D collaboration that investigated CO2 capture from the Preem refineries in Sweden, and subsequent ship transport of captured CO2 for permanent storage on the Norwegian Continental Shelf. The project was conducted 2019-2022 and accomplished: 1) the on-site pilot scale demonstration of amine-based CO2 absorption using Aker Carbon Capture’s mobile test unit (MTU), 2) an in-depth investigation of energy-efficient heat supply for CO2 capture, 3) a detailed techno-economic evaluation of a feasible carbon capture and storage (CCS) chain (from CO2 capture in Sweden to ship transport to Norway), and 4) an investigation of relevant legal and regulatory aspects of trans-border CO2 transport between Sweden and Norway
