Publishable summary: This report serves as the final deliverable for the techno-economic assessments in the CORALIS project’s Swedish demo. Task 6.6, titled “Techno-economic assessments of the Swedish demo case for integration,” has been led by RISE, with participation from WA3RM, Linköping University, and CIRCE.
Based on the amended Grant Agreement (GA) this deliverable should specifically focus on technoeconomic assessments for the Swedish demonstrator in the CORALIS project. The different aspects that were stated in the GA have been addressed, as described below:
– An assessment of other uses of captured CO2.
– An assessment of capturing carbon in the form of earlier stage carbon residual streams in the anchor industry has been done, as well as the use of remaining waste heat in the system.
– An assessment of the Swedish demonstrator.
There were also new subtasks added from the amendment made in the project.
In summary, the deliverable is focused on evaluating the current greenhouse system through various analyses and shaping the future trajectory of the Swedish demo case within the CORALIS project. To enhance clarity and maximize the usefulness of the information, the work done has been organized into three overarching themes: Two themes focusing on the Swedish demonstrator and its development at the existing site (“The Challenge of Supplying CO2” and “Next Opportunities for the Swedish Demo”), and one theme focusing on replication of the Swedish demo to new locations (“Replication of the Symbiotic Greenhouse”).
The theme named “The Challenge of Supplying CO2” was mainly part of the amendment in the project and has not been completed in time to be included in this deliverable, therefore the final results of this work will be reported in D 6.6 at the end of the project. A short summary of work so far with regard to the CO2 challenge has been included in this deliverable. This includes a presentation of the experimental setup and work on tomato sensitivity to different compounds in flue gases, and testing membrane CO2 capture for the contexts in the Swedish demo.
The theme named “Next Opportunities for the Swedish Demo” assesses two cases: the techno-economic feasibility of capturing CO2 from the anchor industry at the Swedish demo-site and producing e-methanol, and utilizing different sludges for pyrolysis and production of biochar. The results from these assessments indicate potential feasibility depending on the design of the system and the value of the products.
The final theme, “Replication of the Symbiotic Greenhouse”, is more explorative in nature and uses the digital system model developed in CORALIS for assessing the impacts of replication of the Swedish demonstrator to two new locations. It also explores the impacts of injecting CO2 and utilizing low temperature excess heat, as compared to the alternative.
