Case Story Denmark

Ringkøbing-Skjern, Denmark

Decentralised Biogas Network Model

Mai 2015

MISSION AND VISION

Ringkøbing – Skjern Municipality (RKSK) in Denmark has adopted an energy supply plan aiming to make RKSK selfsufficient with renewable energy by 2020. It is anticipated that biogas, produced by co-digesting 80% of the animal manure available in the municipality along with energy crops grown on 5% of the municipality’s farmland, will be able to replace 20 % of the fossil fuels.

The biogas will be produced in 40-60 decentralised farm scale biogas plants, connected by a biogas pipeline to the municipal combined heat and power (CHP) plants. The biogas potential is estimated to be of the order of 30 million Nm3 methane from animal manure and slurry and a further 30 million Nm3 methane from energy crops. The decentralised model aims to minimise the transport distances of manure, and makes better use of energy than the traditional farm-biogas plants where it is not always practicable to utilise the available heat. In the long term, the aim is that all transportation of animal slurry will be done by piping, rather than by road.
