Biogas Plant

Odsherred municipality is cooperating with Roskilde University, local companies, the local farming organization and a local heating plant to create a biogas plant in the region of Lumsås.

Odsherred municipality is cooperating with Roskilde University, local companies, the local farming organization and a local heating plant to create a biogas plant in the region of Lumsås.

The biogas plant will be based on local resources from industrial waste products, manure from farms, biomass from straw, seaweed from the beaches and wastewater from the new wastewater treatment plant, all of which are located in the same area.

In Denmark, most biogas plant is built to handle liquid biomass, and there are very few biogas plants using straw because it is a drier substance which requires pre-treatment, and this technology is relatively new in Denmark. The biogas plant in Odsherred could contribute to technological developments in this area.

The advantages of using straw in a biogas plant is that the straw has a high dry matter content, resulting in higher gas production and making the plant more economical.

The same challenges apply to seaweed, since this biomass cannot be fed directly into the plant, and therefore also requires pre-treatment. This technology is also relatively new in Denmark.
In order to ensure that the digested slurry can be spread on farmers’ fields the biogas plant is divided into two tracks: a contaminated track and an uncontaminated track.

The biogas produced is intended to be used for providing energy to Lundbeck’s production site and to the nearby power plant in Nykøbing Sjælland to replace the use of natural gas. Nykøbing Sjælland heating plant has 1,842 customers and supplies 90% of the citizens in the town. The biogas will be used to expand the existing district heating system.

Business opportunities
The biogas plant could be both a construction and investment project

Size of the biogas plant (est.)

  • 100,000 tons of input
  • Construction cost to be around 50 mio DKK
Capacity
Expected gas yield is about 3.5 mio. m3  biogas (equivalent to 5.5 million m3 pure methane, or a gross energy of 35,237 MWh)

Time schedule
The approval process such as EIA, local plan and environmental approval has started in autumn 2016 and the plant is expected to be completed and up and running in 2019. The tendering phase is expected to start in spring 2018.

Distance
Copenhagen City: 98 km
