Schwarze Pumpe

Vattenfall initiated the project in 2001 with a long term research and development project to develop the oxyfuel technology to a commercial application level. By May 2006 Vattenfall could start with the construction of the 30 MW (thermal) lignite oxyfuel pilot plant near its existing 1,600 MW lignite – fired power plant in the industry park “Schwarze Pumpe” near Spremberg in Brandenburg south of Berlin. The investment costs were initially estimated at € 60 million, however according to Vattennfall construction amounted to € 90 million and further € 30 million are being invested in research activities during the project. On 9 September 2008, Vattenfall officially inaugurated the plant and some 45 t CO2 have successfully been separated during the first weeks of operation.

The plant is expected to be in operation for 3 years and will produce about 9 metric tonnes of CO2 per hour, which translates into 75,000 metric tonnes of CO2 per year at full load, approximately 0.6% of the volume of the larger Schwarze Pumpe power plant (10 million ton CO2 annually), currently at a cost of € 80 – 90 per tonne. Linde AG provided the cryogenic air separation and air processing unit, as well as the CO2 liquefaction plant, the boiler has been developed in cooperation with Alstom. Other components, such as a new web based I&C system SPPA-T3000 and connections to the airs separation unit, the CO2 liquefaction facility and the main power plant as well as the field instrumentation was provided by Siemens. The pilot plant is supported by research undertaken at the University of Cottbus (CEBra project with a 0.5 MW test facility) and the University of Dresden (ADECOS project with a 0.5 MW test facility). In September 2008 Linde Group and Vattenfall Europe Technology Research GmbH have further entered into a wide ranging technology partnership with the aim of collaborating on the testing of oxyfuel combustion processes. Linde is supporting Vattenfall with scientific and technical expertise during the first trial phase unit 2011.

Originally, the separated and liquefied CO2 produced by the pilot plant should have been transported by truck to the 350 km distant storage site in Altmark. Public protest in combination with the lacking federal storage legislation has brought the Altmark project to a halt. Vattenfall is investigating in alternative storage sites in Brandenburg and has been considering to send the separated CO2 to the storage project in Ketzin. In the mean time however, at least some parts of the CO2 are trucked off for use in industrial application.

The insights gained during the pilot phase will be utilised to plan a large demonstration power plant with a 250 to 300 MW electrical capacity, around 2012-2015. Then, efficiency and economic aspects will be further investigated and finally the plan is to set up a commercial power plant with the capacity of approximately 1000 MW, around 2015-2020. Progress can be monitored online.

Timing:

Pilot plant construction continues (2007), pilot plant commissioning (2008), demo plant construction begins (2010), demo plant commissioning (2015), and commercial plant operation (2020)
