Marstal Solar District Heating - EU supports the extension to a 100% renewable energy system

In Denmark, the project SUNSTORE 4 supports the further development of the renewable energy supply system for the community of Marstal. The expansion of the solar plant , a new pit heat storage, heat pump and a biomass boiler is part of the innovative cost efficient energy supply system.

 

Marstal District Heating has, through the EU's 7th framework program, received pledges of support for a project called SUNSTORE 4. The contract is signed by Director-General for Energy, Mr Fabrizio Barbaso and the project is, along with 10 other European projects selected to be a part of the so-called "EU flag projects". Besides the fact that Marstal District Heating has received grants for expansion of the current solar installations, the EU has also given grants to disseminate the knowledge, gained through the SUNSTORE 4 project to other European countries. The aim of the project is to demonstrate a large scale innovative, cost-effective and technically 100 % sustainable renewable energy system. Marstal District Heating’s nearly 1,500 members will now receive 55% of their energy from the solar production and 45% of their energy from locally produced biomass (energy willow). The project also includes a heat pump which is "moving" energy to the energy storage and a turbine, a so called ORC (Organic Rankine Cycle) which is an electricity-producing device that can use the energy from the flue gas produced in the biomass boiler. The project will be disseminated to 10 EU countries with the aim to shortly establish 20 similar facilities in Europe. The countries are Austria, Czech Republic, Denmark, France, Germany, Italy, Poland, Spain, Sweden and England.
 
The project involves the following:
  • Expansion of the existing 18,365 m2 solar plant with 15,000 m2 of solar collectors
  • a 4 MW biomass boiler with a built-in ORC power producing unit
  • a 1.5 MW heat pump
  • a 75,000 M3 pit heat storage
 
The total budget for the project is 15,1 mill. Euros. From the EU, the project has achieved 6,1 mill. Euros in grants. The participating partners contribute to the project with 0,4 mill. Euros.
 
The Danish project participants are:
  • MARSTAL DISTRICT HEATING, promoter of the plant
  • SUNMARK is selected as the supplier of the 15,000 m2 of collector area. SUNMARK has chosen the firm Rambøll as their subcontractor.
  • EUROTHERM is selected as supplier of the 4 MW biofuel boiler with parts for the electricity-producing ORC unit.
  •  ADVANSOR is selected as the supplier of the 1.5 MW heat pump.
  • PLANENERGI is consultant for MARSTAL DISTRICT HEATING and is responsible for the technical part of the project.
The European project partners are:
 
  • ENERGY MANAGEMENT AB, Gothenburg, will support the work with innovation of solar and long-term storage and be responsible for evaluation and dissemination of the project results.
  • BIOS, Graz is adviser for the electricity-producing ORC turbine and adviser in the design of the biofuel boiler.
  • SOLITES - Steinbeis Research Institute for Solar and Sustainable Thermal Energy Systems, Stuttgart, is advisor for long-term storage of solar heat and helping in composing the measurement program for the project.
  • EUROHEAT & POWER, Europe’s industry association for district heating, will be responsible for dissemination of project results in Central Europe 
  • AMBIENTE ITALIA, Milan will be responsible for dissemination of project results in Southern Europe.
  • CITYPLAN, Prague, will be responsible for dissemination of project results in Eastern Europe.
 The project runs for a period of 4 years (48 month). Expected start-up is the 1st of July 2010 and expected completion date is the 30th of June 2014.
