Since its establishment in 1990, Linkogas has supplied biogas to the Danish city Rødding. Here the biogas has been converted into CO2 neutral electricity and district heating.
When the biogas supplies to Rødding end, instead, district heating will be produced based on another renewable energy source, straw. So by upgrading the biogas and selling it to the natural gas grid where it will supersede natural gas, all in all, a far more significant environmental advantage will be achieved. At the same time, a waste of heat is avoided during summer where the demand for heat is not high enough to sell the produced energy.
Finally, the access to the natural gas grid offers Linkogas the possibility of increasing the production of biogas which would not be possible otherwise. The expected delivery to the natural gas grid is approximately 6 million cubic meters of natural gas per year corresponding to the consumption of approximately 4,000 households.
Facts about DONG Energy
DONG Energy is the only energy company in Denmark producing bio natural gas.
In 2011, DONG Energy commissioned Denmark's first biogas upgrading plant supplying bio natural gas to the Danish natural gas grid, and the next plant is being commissioned at the Danish biogas producer Horsens Bioenergi.
DONG Energy is Denmark's leading supplier of eco-friendly energy to Danish business customers and for many years, DONG Energy has supplied certified power from DONG Energy's offshore wind farms to climate partners and other customers. With the supplies from DONG Energy's own biogas upgrading plants, DONG Energy can now also supply certified bio natural gas.
