In May 2018, WDS Energiedienstleistungen GmbH, a subsidiary of Energie Graz in Austria, put the unique new heating plant into operation. Arcon-Sunmark is turnkey supplier of the entire project. The facility produces heating via three energy sources: solar thermal energy, a landfill and natural gas CHP-engine and a power-to-heat module, which can use the produced electricity from the CHP system. The heating system in Graz consists of a CHP (120 kW), a power to heat module (120 kW) and a 2,000 m2 solar collector field all combined with a 2,500 m3 storage tank. An expansion of the solar heating production is planned and if implemented

the collector field will reach a total of 10,000 m2. Additionally, the storage tank is designed to take heat from the grid and deliver it back later when needed again. This gives flexibility to other heat generators in the whole district heating grid and to the district heating network in general. POLLUTED GROUND PERFECT FOR SOLAR The landfill project in Graz is not the first time a polluted site has been transformed into a renewable energy facility. Also the Danish town Trustrup- Lyngby did so. Until the end of 2015, an abolished mink feed factory was quite an annoyance for the community. At the same time, the local district heating plant was about to be modernized. The district heating company found that it would make sense to acquire the old factory, demolish it and instead erect a 7,245 m2 solar collector field producing renewable and clean energy to supplement the wood chip plant already in place. In this case, the factory was situated right next to the heating plant. But a collector field can in fact be located several kilometers away from the heating station itself. This means that in areas with a scarcity of available land, it will often make sense to search for vacant industry facilities or similar opportunities in a wider radius. Furthermore, instead of leaving contaminated areas unused for years, a solar heating solution will allow for biodiversity which means that efficient energy supply and environmental considerations do go hand in hand!
