INSURANCE - Utilization of industrial residues for an efficient geological BECCS

Project leader: Glenn Bark (Ore Geology, LTU)

Project team: Io Antonopoulou, Paul Christakopoulos Ayanne De Oliveira Maciel, Ulrika Rova

Partners: Billerud Karlsborg

Duration: 2020-2024

Funded by the Swedish Energy Agency

INSURANCE aims to achieve negative CO2 emissions by capturing and geologically storing biogenic CO2. A novel enzyme-based (i.e. carbonic anhydrase) CO2 capture technique, developed by the Biochemical Process Engineering research group, will be used to boost Carbon Capture and Storage (CCS), using flue gases and lime mud as co-capture agent from a Swedish pulp and paper industry, via the accelerated formation of a bicarbonate solution.

Carbonation experiments at geologically realistic pressure/temperature conditions will be used to precipitate solid carbonates and hence provide a permanent storage form of CO2. The project's focal point lies in developing technologies to convert CO2 emissions from process industries into carbonates while identifying suitable geological sites for CO2 storage. This initiative aligns with the BECCS technology (Bio-Energy with Carbon Capture and Storage), identified by the IPCC, the EU, and the Swedish government as crucial for achieving Sweden's climate goals of net zero and negative greenhouse gas emissions by 2045.
