Lübeck, Germany (largest solar thermal plant in Schleswig-Holstein federal state)
Summa Energy has been selected as general contractor to build a 9 MW solar thermal system on behalf of Stadtwerke Lübeck Energie GmbH for its district heating network, which supplies households in the Moisling city district with healthy heating. Only 788 pieces of Savo 16S large scale high performance flat plate collectors are sufficient to getting combined with an 3,000 m³ heat storage tank and produce carbon free heat for the needs of all connected consumers.
Additionally, a PV system will be built on site to generate the electricity consumed by the solar pumps, thus unburdening the local power grid.
The scope of supply includes also all the land works, the construction of a technical building and the supervision system to operate the plant in automatic mode.
A new forerunner project on the large scale solar thermal market in which Savosolar has been involved: The first solar thermal field with double glasses collectors on trackers. This innovation has been done to optimize the annual solar production with a limited available area. This new solar thermal plant is a property of newHeat and will delivered heat the network of the city of Pons, which is managed by Dalkia.
Savosolar supply on this project consist in the complete solar field field as a turnkey solution, it means, the design, the supply and the installation of the solar collectors and its trackers, as well as the piping, until the solar station. It represents 112 Savo 15 DG-M collectors, which will reduce of 210 tons per year the CO2 emissions for the city’s heat needs.
Savosolar’s first commercial solar cooling system was delivered to a school in Ukraine. The entire school was pre-fabricated in Finland and delivered to Ukraine by Elemenco Oy.
Outside of the cooling period, the solar thermal system produces energy for domestic hot water and space heating needs. During the hot summer time, three adsorption chillers cool the building via the air handling unit. The adsorption chillers, which were delivered by Savosolar, are driven by the solar thermal system.
This solar thermal plant, the largest in Europe for industrial process, will deliver on average 4,000 MWh/year of heat. It will cover nearly 32% of the heated water need for the steam generation in the local paper mill. With the very high solar yield – more than 1,000 kWh/m2 – this solar thermal field is the first of its kind in the world due to Savosolar high efficiency solar collectors installed on a single-axis tracking system, manufactured and installed for Savosolar by Arcelormittal, Project Exosun. 66 tilting structures, each carrying four 16 m2 collectors, follow the sun from morning to evening and maximize the heat production.
The project was developed and financed by NewHeat and Savosolar acted as the EPC contractor. Meaning, Savosolar designed the whole system, delivered the solar collectors, and realized the installation with local French companies. This installation will be a reference for the huge growing market of heat-as-a-service for industrial clients in France and world-wide.
