Economical feasibility and potential of CO2 capture, storage and reuse in Finland was evaluated under the National Programme on Technology and Climate Change (Climtech). In Finland, no suitable geologic formations exist to sequester CO2. The nearest potential CO2 sequestration sites are offshore oil and gas fields in the North Sea and Barents Sea, which would mean a transport of 500–1000 km for captured CO2. With current knowledge, capturing CO2 near the storage sites and investing to new cross-border electricity transmission capacity seems the most feasible option for Finland. Storing CO2 as solid mineral carbonate could be an option in the future, since large resources of suitable silicates exist in Finland as natural minerals and as wastes of mining industry. The reuse potential of captured CO2 is less than 0.5% of the annual CO2 emissions.
