Partners from 13 European countries kicked-off the EU project SDHplus on solar district heating

It is the objective of SDHplus to analyze on international level the specific opportunities for solar thermal in district heating, to develop them as new business models in cooperation with relevant market stakeholders and to pilot implement show cases.

More than 30 experts from 13 European countries met on 5 and 6 July in Stuttgart and Crailsheim for kick-starting the EU project SDHplus. Beside the experts from more experienced countries, which already cooperated in the predecessor project SDHtake-off, new partners from Croatia, France, Lithuania, Poland, Slovenia and Spain joined the team. ‘Already at this first meeting we could discuss in detail interesting opportunities for large scale solar heating plants in these countries with new markets and we are satisfied about this extension with motivated project partners.’ says Thomas Pauschinger, project coordinator from the German Steinbeis Research Institute for Solar and Sustainable Thermal Energy Systems Solites.



Concrete opportunities for solar thermal in combination with district heating often result from situations, where specific boundary or operation conditions lead to additional advantages and synergies. It is the objective of SDHplus to analyze such specific situations on international level, to develop them as new business models in cooperation with the relevant market stakeholders (heat suppliers, local authorities and housing enterprises) and to pilot implement show cases.

Key approaches are:

  • developing and pilot implementing new business models for SDH focusing on situations, where renewable district heating is used for enabling buildings with high energy performance
  • the use of solar thermal in cases where the use of CHP district heat is not anymore used for the base load due to high shares of wind energy and PV in the electricity grid and a resulting shift of the merit order
  • the integration of solar thermal into isolated heat networks without CHP and the substitution of heating-only plants
  • the use of the modern and environmentally friendly image as well as the high acceptance in society of solar energy for a wider diffusion and marketing of district heating

The project further aims at know-how transfer and market preparation in countries with new markets. Already on 27 and 28 September of this year, the project partners invite to a practical international workshop on solar district heating held in Braedstrup, Denmark. ‘We can show innovative solar, heat storage and district heating technology, but will also share our rich experiences regarding local energy policy and urban planning.’ states Per Kristensen, CEO of Breadstrup District Heating.

More information about SDHplus and details of the Braedstrup Workshop are available on www.solar-district-heating.eu.

SDHplus is supported by the Intelligent Energy Europe Programme.
