Within research and development our most important focal points are the development of highly efficient power plants, renewable energy sources and technologies to reduce the impacts on the environment of our power plants. The three main projects right now are:

RESEARCH, DEVELOPMENT AND DEMONSTRATION

AD700 – Advanced steam data, 700 degrees Celsius steam temperatureThe objective of the project is to develop new materials which will allow an increase of the boiler steam temperature to 700 °C to ensure a higher output rate and lower CO2 emissions.

CASTOR – CO2 from Capture to StorageThe objective of the project is to separate CO2 from the power plant flue gases and to investigate the possibilities of re-using the carbon dioxide for enhanced oil production in oil fields.

IBUS – Integrated Biomass Utilisation System The objective of the project is to process biomass like straw into ethanol (alcohol) for use as an additive to gasoline. The process is energy-heavy and there are good synergies to be obtained in the production of ethanol in connection with power plants.

The quantification of the environmental impactat different production/consumptionscenarios is important for DONG Energy'sdecision process.

The results of CEEH will undoubtablyinfluence the political process in Denmark.Therefore it is important for us to follow the work to see that

• right data are used for the CEEH calculations• correct assumptions about future technology are used for the scenarios

Since 1997 DONG Energy have been investigating our environmental impacts throughLife Cycle Assessments.
