Swiss startup Climeworks AG has announced plans to build a direct carbon dioxide capture (DAC) plant in Iceland. The installation, which will begin construction on June 29, could be the largest facility of its kind, Reuters reported.
The project, called Mammonth, will have a capacity of 36,000 tons of CO2 per year, 10 times the size of the existing Climeworks plant, which is considered the largest DAC in the world. Construction will take 18 to 24 months.
Mammonth will contain about 80 units of fans and filters that draw air in and extract CO2 from it. The gas will then be mixed with water and pumped underground, done by the Icelandic company Carbfix.
The plant will be powered by a nearby geothermal power plant. The cost of the project will be at least $627 million.
Previously, the UN Intergovernmental Panel on Climate Change said that energy-intensive and costly technologies such as DAC would be required for large-scale CO2 removal in the coming decades to limit global warming to 1.5°C and avoid increasingly severe climate impacts.
Plus-one.ru talked about a project to turn carbon dioxide emissions into baking soda in the UK. The raw material for production will be exhaust gases from a gas-fired power plant.
