Asnæs power station can now supply green district heating to the Danish city of Kalundborg and green process heat to Novo Nordisk and Novozymes. The new wood chip-fired power unit was recently inaugurated by HRH Frederik The Crown Prince of Denmark, an event that also marked the phase out of coal in Denmark.
Following more than three years' intensive work on the conversion by Ørsted, the plant will no longer burn coal. It’s wood chip will primarily come from forestry by-products such as branches, twigs, and thinned wood. All suppliers must ensure that the wood chips come from sustainable forestry where the forests are replanted, and biodiversity is protected.
"The future belongs to sustainable energy sources such as wind, solar, and biomass. Therefore, we'll be phasing out coal at all our power stations by 2023, and the decision about Asnæs Power Station, which was made together with our customers, is an important step on the way," said Morten Buchgreitz, Ørsted executive vp and CEO of Markets & Bioenergy.
The 20-year steam and district heating contract involved the construction of a new wood chip-fired plant, which is connected to the power station's existing installations and systems. This will enable Asnæs Power Station to supply steam, district heating, and power. Consequently, Kalundborg is retaining the advantages of the symbiosis between power station production, steam supply, and district heating.
The conversion will result in an annual reduction in carbon emissions of around 800 000 tonnes andcontributes significantly to Denmark's green conversion.
The conversion also marks a significant change in Novo Nordisk's largest production unit in Kalundborg, which has set a target of zero carbon emissions from global operations and transportation by 2030 at the latest.
