The CO2 containing gas will be used as feedstock for validation of a novel CO2 capture and storage process we develop under the INSURANCE project.
The INSURANCE project builds on the BECCS technology (Bio-Energy with Carbon Capture and Storage) which is one of the technologies that IPCC, EU and the Swedish government points out as critical for how Sweden should reach the climate goals regarding net zero and negative emissions of greenhouse gases by 2045.
Today it is still cheaper for the industry to emit CO2 to the atmosphere compared to capturing the gas and later store it. One of the more expensive steps in BECCS is the separation of CO2 from the industry flue gases. Within the INSURANCE project, we therefore develop and optimize a capturing technology that is expected to be more energy efficient. The novelty is that we use internal by-products from the pulp and paper industry, in this case BillerudKorsnäs, to capture CO2 together with an enzyme, that accelerates the sequestration step. Moreover, the potential for land-based geological storage of CO2 in Sweden will be investigated for the first time.
INSURANCE is a collaborative project between the Ore Geology group and the Biochemical Process Engineering group at LTU, together with the pulp and paper industry BillerudKorsnäs Karlsborg.
