CCS - Carbon Capture and Storage at Vattenfall
Climate change is one of the greatest environmental challenges of our time. As part of ongoing research and development efforts, Vattenfall initiated a project on carbon dioxide capture and storage (CCS) in 2001. The goal of the project is to develop the technology further until it can be used in power plants.
Climate change is a threat that seriously needs to be tackled; hence we need to significantly reduce the amount of emitted carbon dioxide (CO2). Alternative and sustainable sources of energy are being developed but need more time before they can be commercialised and fully deployed on the market. Fossil fuels will be needed during the transition period. CO2 capture and storage (CCS) can support the transition to a low CO2 energy system in the near future.

At Vattenfall, a number of test rigs, EU projects and joint efforts at different pilots and research stations around the world have given us great knowledge and experience. It has also secured the company’s belief that CCS is a viable concept and that CCS is absolutely necessary to quickly start reducing global CO2 levels.
The different methods available for capturing CO2 aim at producing a concentrated stream of CO2 that can be readily transported to a suitable storage site for injection underground. There are three principal ways to capture CO2 produced in power plants: Oxyfuel combustion, Postcombustion and Precombustion.
Vattenfall has built a 30 MW pilot plant for carbon dioxide capture at the lignite-fired power plant at Schwarze Pumpe, Germany. The plant was inaugurated in 2008, and since then tests are performed to evaluate the technology of Oxyfuel combustion.
Through Nuon, Vattenfall has built a pilot plant at the Willem Alexander power plant in Buggenum, Netherlands. This pilot, that use the Precombustion technology of CCS, was taken into operation in 2011.
