DONG Energy has started the construction of a demonstration plant in Denmark. The principal purpose of the demonstration plant is to show that DONG Energy’s second-generation technology can be applied on a large scale, i.e. that large-scale production of ethanol from straw is possible.

The plant will also demonstrate that integration with a power station, enabling the residual biomass to be combusted, thereby generating more energy than is used by the plant itself, results in efficient and financially viable energy utilisation.


The investment is in the range of 300 mio kr, and for the design and engineering Inbicon has received support from the Danish Energy Authority. The bioethanol plant will be integrated with a coal fired power plant,and hence it’s possible to increase the overall efficiency. The demonstration plant will have three outputs: ethanol, biofuel and animal feed.

 Unique collaboration at the port in Kalundborg
DONG Energy’s demonstration plant for production of bioethanol will be located in Asnćs Power Station’s area bordering on the dock in Kalundborg. This will enable the bioethanol plant to be part of the collaboration that involves many other companies in the port area.

The companies utilise each other’s residual products in a sustainable cycle that benefits each company financially and is also environmentally beneficial. Statoil’s oil refinery and Dansk Landbrugs Grovvareselskab, DLG (Danish Cooperative Farm Supply) are situated at the port.

The refinery can receive bioethanol from the demonstration plant and blend it with petrol. DLG and other agricultural enterprises can supply the bioethanol plant with straw and can sell the feed products from the bioethanol production.
