First SDH workshop with Danish experts in France
A two days workshop was held in Paris last June, to allow discussions between local authorities, DH companies, manufacturers and consultants from both DH and solar sectors.

 

The first day was a session with 13 expert participants which allowed detailed case studies and technical presentations. The second day targeted a larger audience and, with more than 60 persons, was dense with many discussions with the coaches and between the participants. This wide and diversified audience allowed to have a presentation from the ministry on how DH and solar are taken into account in the building code, which confirmed that there is currently no real incentive for SDH. The dynamic shown by the group was a good opportunity to demonstrate the necessity for evolutions in the code. The history and perspectives of the Danish market was very much appreciated, especially presented directly from enthusiast speakers who have been actors of this successful development from the start.

One of the biggest lesson of this workshop was given through the Chambéry (Alps) project: SDH market in countries like France where most existing DH are running on high temperature is not restricted to new DH. Indeed, with a 160°C input temperature, integrating solar was a bit of a headache, but a smart way around this difficulty was found: solar collectors will be installed on an independent – low temperature – loop fed by the main grid on the return pipe. Using the return pipe to provide heat to this loop brings another advantage: a reduction of heat losses thanks to a decrease of the return temperature.

The most appreciated presentations where unsurprisingly those showing well advanced projects in France, hence confirming that solar on district heating is possible, even in a country whose energy background is quite far from the Danish one.

As a conclusion, it was both interesting and encouraging to see that two sectors who had previously little in common have now a lot to do together: from a district heating actors point of view, SDH is seen as a new opportunity to improve the sector’s image among the public and hence continue to develop district heating as a whole, whereas from a solar actors point of view, SDH brings a great opportunity to develop solar thermal.
