“Techno-Economic Feasibility Study of the Implementation of Carbon Capture from Major Emission Sources at Preemraff Lysekil” (PREEM CCS)
Project partnersAker Solutions S, Preem A, SINTEF Energi, Chalmers University of Technolgy, Equinor AS
This PREEM CCS project, is a continuation of the CLIMIT-Pre-study “CO2 capture and liquefaction at Preem refineries in Lysekil or Gothenburg, Sweden, for storage of CO2 on the Norwegian Continental Shelf” (Grant no. 617339) and, has the following work packages:
0. Project management and dissemination
1. CO2 capture demonstration and feasibility
2. Process evaluation of full-scale CO2 capture integrated at Preemraff
3. CCS value chain analysis, CO2 transport and integration in the Norwegian full-scale CCS project
4. Identify actions to overcome the legal and regulatory barriers for transborder ship transport and storage of CO2 from Preemraff Lysekil for storage on the Norwegian Continental Shelf
5. Roadmap for CO2 emission reductions at Preem in relation to Sweden’s net-zero emissions target for year 2045
Preem AB (Publ) – or Preem – is one of the largest CO2 emitters in Sweden (1.5 Mt CO2/year in their refinery in Lysekil and 500 kt CO2/year in the Gothenburg refinery). At the Lysekil refinery, the Hydrogen production facility alone emits 480kt CO2/year. The geographical location of Preem on the Swedish west coast means that it is relevant to consider a connection to the Norwegian full-scale CCS project: CO2 captured by Preem can be relevant to ship to the planned CCS hub on the Norwegian west coast, for permanent offshore storage east of the Troll field.
As a major industrial emitter of CO2 in Sweden, Preem is ready to tackle its part of the Swedish challenge to be climate neutral by 2045. They are interested in finding solutions to radically bring their CO2-emissions down, by testing CO2 capture at their refinery in Lysekil. Preem has already had a research collaboration with Chalmers Institute of Technology on CCS-related topics (mainly CO2 capture) since 2010. Preem also participated in the NORDICCS project, a networking project between Nordic industry, research institutes and universities that pursued Nordic industrial CCS cases and evaluated their feasibility in terms of technology and cost.
The demonstration of carbon capture at the hydrogen production unit (HPU) at Preemraff Lysekil using the Aker Solution mobile test unit (MTU) for pilot-scale testing of CO2 absorption is a main project activity. Furthermore, the project will put the demonstration into the context of a pathway towards full scale implementation of CCS and, thus, evaluate full-scale CO2 capture from the HPU, and other major emission sources at the refinery.
The project will also evaluate the technical feasibility and cost of the full CCS chain including CO2 transportation and storage on the Norwegian west coast as well as relevant legal aspects related to trans-border CO2 transport and storage and national emissions reduction commitments in Norway and Sweden.
The project presents a unique collaboration between Swedish and Norwegian research and industry partners to demonstrate synergies between CO2 capture from Swedish large-scale emission sources and the Norwegian full-scale CCS project. The target for Sweden to become climate neutral by 2045 will require CCS to be deployed, especially in the process industry, and the lack of feasible infrastructure for storage of CO2 in Sweden poses a challenge. However, the relative proximity to Norway, with its plans to realize a full-scale CCS chain by 2022, presents opportunities to realize CCS from Swedish emission sources.
This kind of international collaboration on full-chain CCS realization is strongly in line with the Norwegian national strategy for research, development, demonstration and commercialization of new energy technology, Energi21, where CCS has been identified as one of the priority focus areas with one of the key ambitions to review imports of third-party CO2 to a Norwegian central CO2 storage site.
The project aims to identify possibilities for cost reductions in different parts of the CCS chain: 1) through use of refinery waste heat for solvent regeneration to reduce capture costs, and 2) through supply of CO2 from large Swedish sources to reduce transport and storage infrastructure costs in the Norwegian CCS chain.
The international nature of the project and the importance of international governmental collaboration to realize a full CCS chain from Swedish sources will be a focal point. Therefore, there will be an emphasis on informing both Swedish and Norwegian authorities on the progress and results of the project and engage in an open and continuous dialog during the project.
