New technologies gaining momentum
The continued technological development of carbon sequestration solutions is crucial to meet the need for carbon emission reductions and the removal of excess carbon from the atmosphere. Geological storage of captured carbon is one promising technology. Direct Air Carbon Capture and Storage (DACCS) and Bio Energy Carbon Capture and Storage (BECCS) are other pathways to scale up technological solutions for climate change mitigation. All new technologies should be assessed carefully, to determine where captured carbon is best used, considering the limited storage capacity.
Being a Nordic company, the development and management of forests are close to our heart. Forestry offers opportunities to produce renewable fuels and use the residues to replace fossil products – which will store carbon at the same time. The organic material Lignin, a residue from renewable fuel production, can be refined into biochar, which in turn can be used in soil application products and/or as an additive in asphalt. The total amount of carbon efficiency is calculated by deducting the total life cycle emissions from the total stored carbon. Biochar is a well-known product with a proven solid permanence.
Today, the oceans sequester around 70 % of the world’s carbon dioxide through natural processes. We want to safeguard and improve that capacity through various initiatives. We are closely following the developments in algae carbon sequestration, mangrove preservation and wetlands restoration. Mangroves and wetlands are important carbon sinks and reservoirs, and they also fulfil important ecosystem functions, like water cycling and biodiversity richness. Algae projects can be a very effective solution for sequestering large amounts of carbon, and algae can also be harvested and used as feedstock to produce biofuels, natural fertilizers, biochar and animal food.
