Can Oxyfuel combustion be the method of choice to capture carbon dioxide?
The purpose of the pilot plant is to validate and improve technology around capturing carbon dioxide. There are three main methods for capturing carbon dioxide. Vattenfall has chosen to test the Oxyfuel capture technology at the pilot plant since it builds on existing power-cycle technology. It is also currently the most promising method with regard to costs for capturing carbon dioxide at power plants. A challenge, however, is the air separation step that demands large amounts of energy. Carbon dioxide captured in the pilot plant will have the right properties to be transported and permanently stored deep underground. Vattenfall is currently searching for a suitable storage site to be connected to the pilot plant.
