HeidelbergCement and its Swedish subsidiary Cementa are stepping up their activities with one of Sweden’s largest climate transition initiatives: At the end of May, the promising results of the pre-feasibility study for a carbon capture and storage (CCS) facility at Cementa’s plant in Slite were presented at a press conference. A new grant from the Swedish Energy Agency will support the next steps towards carbon-neutral cement production in Sweden by 2030.
The Slite plant has a favorable location directly at a sea-harbor, and there are several storage solutions under development in the North Sea where Northern Lights is the most advanced today.
The installation at the Slite cement plant on the Swedish island of Gotland will be scaled to capture up to 1.8 million t of CO2 annually, which corresponds to the plant’s total emissions and is equivalent to 3% of the country’s total emissions. Additionally, the use of biobased fuels in the cement production at Slite will be increased in line with HeidelbergCement’s commitment to significantly raise the share of biomass in the fuel mix. The full-scale capturing of the plant’s CO2 emissions is targeted by 2030.
In the pre-feasibility study, amine capture was found to be the most suitable technology. The implementation of the capture facility requires significant rebuilding and extension measures to the plant – a process that is starting now to meet the schedule. The power demand will also increase significantly.
