Solrod Biogas Plant Investment Project (SOLROD)

Project brief
Key action: Mobilising Local Energy Investment
Status: Closed
Coordinator: Mr. Rasmus Bo Hansen
Solrod Municipality, Denmark
Tel: +45 56182334
Partners: Solrod Municipality (Solrod ), Denmark
Benefits: High replication potential for the concept of this biogas plant, in particular, for coastal areas around Europe that are facing similar environmental and economic problems deriving from seaweed. Approach to engage all important stakeholders in the process of building the biogas plant is a exemplary.

Contract number: IEE/11/MLEI/080


The municipality of Solrød in the Zealand region of Denmark is a Covenant signatory and has already submitted a SEAP which commits to achieve a 55 % greenhouse gas emission reduction by 2025. Studies have shown a viable basis for constructing a CHP biogas plant using three main fractions: cast seaweed collected from the beaches at Bay of Køge (Køge Bugt), organic waste from the local pectin and carrageenans production facility and manure from local pigs and cattle farms. An annual CO2 reduction of approx. 40.100 tons (equal to 28 % of the municipality’s current CO2 emissions) has been projected in the feasibility study. The major objective is to ensure the launch of the CHP biogas plant in the Municipality of Solrød bringing a multitude of beneftits for local stakeholders and the wider community including the delivery of renewable energy into the district heating network with approximately 370.000 inhabitants. The MLEI support will ensure financing for the final preparation phases, including support for project management, tendering technique and communication management. The project will trigger investment of EUR 12.467.000.

  • Reduction of CO2 emissions by replacing fossil fuels (approx. 40.100 tons CO2/year) and production of 55 GWh/year of renewable energy from sustainable sources.
  • Contributing to solve problems with aquatic pollution. Removing the seaweed in Køge Bay will diminish the load of nutrients, which today is a major problem of the aquatic environment. It will also solve problems with odours from seaweed & algae which is a nuisance to the local community.
  • Delivery of 72 % of the current 2015 target of the EU Water Framework Directive for nitrogen reduction in Køge Bay and more than 100 % delivery of the reduction targets for phosphor levels. Using cast seaweed will remove 120 tons Nitrogen/year & 9 tons Phosphor/year.
  • Knowledge-sharing regarding potentials for improving sea water quality and recreational use of the maritime environment by collecting cast seaweed for renewable energy production.
  • Biomass treated in the biogas plant (digested biomass) can be used as biological fertilizer which is a more efficient fertilizer than other non-treated biological fertilizers, and as substitute of chemical fertilizers on farmland in the area.
