Vattenfall's plans for demonstration plants

A demonstration plant is the link between the pilot plant and a fully-developed commercial concept. In the pilot plant, the technology itself and the process will be validated, whereas in a demonstration plant the commercial abilities of the technology will be proven.

Initial studies for demonstration plants have already begun within the Vattenfall Group and two sites have been chosen so far. In northern Denmark, we are investigating the possibility of storing CO₂ at the Vedsted structure, a geological reservoir between one and two kilometres below the Earth’s surface. If the site proves suitable for CO₂ storage, the Nordjylland Power Station will be equipped with a full-scale unit for CO₂ capture using Postcombustion.

The carbon dioxide will be transported through a pipeline across the 30 kilometres between the plant and the storage site. 

In Germany, we will turn the Jänschwalde power plant into a demonstration plant. Parts of the existing plant will be equipped with units for CO₂ capture and we are currently investigating the possibilities of implementing both Oxyfuel and Postcombustion technology at Jänschwalde. This demonstration plant can be realised by the year 2015. It has not yet been decided where the captured carbon dioxide is to be stored, but Vattenfall has initiated exploration of two storage sites in the state of Brandenburg.
