The solar thermal plant of Verdun will supply 8 GWh of decarbonized heat for the Lacto Serum factory nearby. With an area close to 15,000 m2, it became the largest solar thermal installation for industrial process heat in Europe, exceeding Issoudun’s plant, commissioned in 2021 by Savosolar, with a few hundreds m2.
This plant is the property of Newheat and Savosolar has been chosen to realize the solar thermal field as a turnkey project.
Savosolar delivered -once again- the largest solar thermal installation in Finland. This system is located way North in Tupos, Liminka – less than 200 km from the Arctic Circle.
The heating load of Tupos district heating is usually covered by wood pellets. Yet during summer time, the load is often so low, that the substantial wood pellet burner cannot be properly used and an oil burner got used, instead. The special challenge here has been to design a very efficient solar thermal system that could replace the oil consumption in summer to run the district heating network almost completely fossil-free.
Savosolar has been selected to deliver a tracker mounted solar thermal plant for the district heating of Nansha, Guanghzou, China. The system is combined with a geothermal seasonal storage and a chiller (not in Savosolar’s scope of supply) which allow the owner to deliver healthy energy, both heating and cooling, to its customers.
As a general contractor, Savosolar built a solar thermal system on behalf of Fernwärme Ettenheim GmbH for the largest possible solar feed-in into the existing district heating network. 112 pieces Savo 15 SG-M large collectors generate fuel-free healthy heat, which is temporarily stored in two 100 m³ buffer storage tanks.
This also allows the operating hours of the CHP and the biomass boiler to be optimized. The scope of delivery included the fence and video surveillance system, as well as the creation of a meager meadow to enrich local biodiversity.
The construction work was temporarily interrupted due to the COVID19 restrictions. All system hydraulics were completely housed in a container. The keys were handed over in October 2020.
A PV system still to be built on the east side will generate the electricity for the pumps in the future.
