The project to capture carbon dioxide
Focusing on capturing and storing carbon dioxide from coal-fired power plants, the project is designed to achieve secure, cost-effective and feasible technologies for an almost complete elimination of carbon dioxide emissions – allowing us to produce energy that does not contribute to global warming.
The idea is to capture carbon dioxide from the power plant's flue gases, compress it into a liquid, and permanently store it deep underground in suitable geological formations. Most of the carbon dioxide will dissolve in the reservoir water, and then very slowly mineralise. An important part of the project involves identifying and assessing the local environmental impact of CO2 capture, transport and storage.
The pilot plants
Vattenfall has built a 30 MW pilot plant for oxyfuel carbon dioxide capture at the lignite-fired power plant at Schwarze Pumpe, Germany. At the pilot plant, tests are performed to evaluate the technology before building a larger scale demonstration plant.
The goal of Vattenfall's research and development within pre-combustion carbon capture is to demonstrate the technology at the pilot plan in Buggenum, the Netherlands, in order to verify technology performance, generate knowledge and improve performance of shift catalysts.
The work is undertaken in cooperation with researchers from the Delft University of Technology in the Netherlands, the Energy Research Centre of the Netherlands, and Vattenfall Research and Development.
A post-combustion pilot plant, designed to capture 100 tonnes of CO2 per day, became operational in March 2012 in Ferrybridge. The plant was built in cooperation with our partners Doosan Power Systems and SSE, and with funding support from the British Department of Energy and Climate Change (DECC). During the two-year test phase, special attention will be given to optimising energy efficiency, dynamic operation and environmental performance.
