DONG Energy has in-depth knowledge of how to obtain energy synergies by integrating bioethanol plant and power station processes. In
Inbicon's concept bioethanol is produced at specially designed plants built close to power stations. This allows an eco-friendly cycle of use and re-use between the plants.
- Eco-friendly energy synergies
- New state-of-the-art demonstration plant
Energy savings as a result of integration between bioethanol plants and power stations are an important element of Inbicon's bioethanol concept. Building bioethanol plants close to power stations allows an eco-friendly cycle of use and re-use.
Surplus energy reduces costs and emissions
In Inbicon's concept there are a number of synergies to be gained between bioethanol plants and power stations. For example, a bioethanol plant produces more energy than it consumes to convert the biomass and the end result is an energy surplus that reduces costs and emissions in both bioethanol plant and power station.
Reusing wastewater
Also, the bioethanol plant has been optimised so that it produces a very small volume of wastewater. The wastewater can be used in the power station in the flue gas treatment process, reducing the power station's fresh water consumption.
Utilising waste heat from power generation in bioethanol production
The synergies between a bioethanol plant and a power station work both ways in Inbicon's concept. Waste heat from power generation at the power station can be utilised for processing straw at the bioethanol plant.
State-of-the-art demonstration plant
In November 2009 a state-of-the-art second-demonstration plant was inaugurated near the Danish town of Kalundborg. The plant will be capable of processing around 30,000 tonnes of straw and producing approximately 5.4 million litres of bioethanol per year. The plant applies our second-generation bioethanol technology on a large scale and demonstrates energy integration with a power station.
