Combat climate change through technology

Carbon capture and storage

CO2 capture and storage, or CCS, is a technology value chain which captures CO2 before it is emitted to the atmosphere and transporting it to store it safely, deep underground.

The capture technology which will be tested and improved at TCM, is an important part of providing a commercially viable tool to deal with carbon dioxide emissions. This will provide an important link in completing the CO2 value chain.



CO2 can be captured from a variety of sources including flue gas from power production; natural gas processing sectors; as well as emissions intensive industrial sectors like steel, iron cement and chemical production.



The captured CO2 must be transported to the storage site. This can be done via pipelines or ships. CO2 is transported in liquid form and can then be injected to the storage site. CO2 pipeline transport has been done for decades contributing to sound understanding that it is safe and feasible.



CO2 can’t just be stored anywhere: for deep underground storage, geologists must identify the right areas with the necessary characteristics to ensure the CO2 will be stored for a long time to come – ideally up to thousands of years. A suitable storage site must be a high porosity formation with a good ‘cap rock’ which seals the storage formation and will prevent any CO2 from seeping up to the surface.


The Utsira geological formation, 1000 metres deep below the North Sea, is home to the world’s first offshore CO2 storage site. Since 1996, more than one million tonnes CO2 each year have been captured from the Sleipner gas field and stored in a saline aquifer. As one of the first projects, the way the gas is spreading has been monitored closely and mapped by various research projects funded by the EU.
