Technology partner for the oxyfuel process
In the oxyfuel process, the coal is combusted in an atmosphere of practically pure oxygen and recycled flue gas instead of with the customary ambient air. The result is a mixture of carbon dioxide and water vapor. Following condensation of the water vapor, the CO2 share in the flue gas amounts to over 90% by weight (dry). Given removal of pollutants, such as SO2, NOx and dust, beforehand, the carbon dioxide can then be stored under these conditions without any further treatment.
Hitachi Power Europe is involved as a technology partner in the "Schwarze Pumpe" oxyfuel pilot unit of energy supplier Vattenfall and is carrying out combustion tests there. In view of its references and manufacturing scope - extending from the utility steam generator and firing technologies through to environmental engineering equipment and turbines - our company is ideally placed to supply components for future oxyfuel process equipped power plants. This technology can also be retrofitted into existing plants.
In addition, Hitachi Power Europe specialists are working on numerous projects with power plant operators, plant constructors, universities and institutes in the oxyfuel research field.
