Theme: Concentrated solar thermal in heat transition

Solar thermal and, in particular, concentrated solar thermal are relatively unknown in the Netherlands. Flat plate collectors are, however, used in homes and also increasingly in district heating. Vacuum tubes are also increasingly finding their way. But concentrated solar thermal is not yet applied in the Netherlands. This is curious because in all our neighbouring countries: Belgium , Germany, Denmark and even Sweden, it is already being used for not only heat networks, but also for process heat in industry....

The Association for Solar Power Plants organised a meeting in Gouda on 28 August especially for anyone working in or dealing with the heat industry. The aim of this meeting was to share knowledge and experiences about this still relatively unknown technology and its application possibilities for sustainable heating of the built environment, via heat networks, for example, in the Netherlands.

At the meeting, examples from Belgium and Germany were discussed in detail, by people directly involved. See the programme and registration

In fact, by concentrating sunlight, you can easily achieve higher temperatures.

For households, this has the advantage that in principle you could continue to use your ordinary radiators and hot tap water can also be supplied, for industry it means that they can get a large part of their heat demand (process heat) or cooling from CST (Concentratied Soilar Thermal).

Also noteworthy is that three times more energy can be harvested per square metre of aperture area than with PV, In our country with limited space, a tremendous advantage. Fraunhofer image

If you further consider that more than 50% of our energy demand consists of heat, you do not understand why our foreign examples have not yet been copied in the Netherlands. See also the VZKC report Focus on the heat transition

Speakers:

Marc Peters of Darel bv This company guided Azteq (Belgium) in the construction of 3 trough plants built in Belgium, two for industry and 1 for district heating.

Carsten Corino, & Amelie Krahl of Sunoyster, (Germany): This company has designed a special trough mirror that can not only track the sun from east to west, but also rotate with the sun. Moreover, solar panels can be attached to the system, allowing it to produce electricity in addition to heat. In addition, some members of our society will briefly tell in a pitch what they are working on.

VZKC

After several meetings devoted to hydrogen from the desert, we thought it was time to see what CSP could mean in the Netherlands. To this end, we wrote a VZKC Focus paper(see Focus on the heat transition) in the spring, which was well received. The province of South Holland invited us for a meeting and we had several discussions with the Netherlands Environmental Assessment Agency about usefulness and necessity. In addition, the engineering consultancy Sweco has shown interest and they have plans to translate the report into English.
