Avery Dennison has commissioned Europe’s largest Concentrated Solar Thermal (CST) platform and thermal storage unit at its production plant in Turnhout, Belgium. The renewable energy project contains a CST platform of 2,240 surface mirrors, with a solar field peak yield of 2.7 GWh thermal power, and six thermal storage modules with a capacity of five MWh thermal power.

The renewable energy platform, consisting of a CST field and thermal storage unit, covers roughly 5,540 square meters on site, and will contain the largest installation of parabolic mirrors combined with thermal energy storage in an industrial setting in Europe. In operation, the total installation will provide heat equivalent to 2.3 GWh of gas consumption, reducing the plant’s greenhouse gas emissions by an average of 9% annually. During summer months and high-sunshine periods, it will provide up to 100% of the factory’s heat demand.

The project is a collaboration with Azteq, an organization that builds, develops, and maintains CST facilities; ENERGYNEST, a long-duration thermal energy storage (TES) provider; and local community group Campina Energie, which helped secure a portion of the project financing.

The CST platform, built by Azteq, will concentrate energy from direct sunlight into a collector tube filled with absorption liquid, like thermal oil. Additionally, thermal energy from this process will be stored in ENERGYNEST’s ThermalBattery™ and dispatched on demand as secure, green heat. When coupled with the six battery modules, the CST platform can produce and dispatch high-temperature thermal energy both day and night on demand. The solar field, thermal storage, and heat distribution system of the Avery Dennison production facility is all connected by the Balance of Plant (BoP) by AURA GmbH & Co. KG, and used for heat shifting between the heat sources and heat sinks.

By supplying zero-carbon solar energy, the project will help provide heat to run drying ovens, which are used during the coating process of pressure-sensitive adhesive products manufactured at the site. These products are used in industries such as automotive, building and construction, medical devices, and personal care.

Campina Energie, which is engaged in green energy projects and represents more than 1,000 Turnhout residents, helped to secure financing for the project. The ENERGYNEST thermal battery installation received funding from the European Union's Horizon 2020 research and innovation program. Azteq’s CST platform is partially funded by the Flemish Government via the call Green Heat.

“The greatest potential for energy is in our own hands. Here in Turnhout, Avery Dennison, Azteq, ENERGYNEST, and Campina Energie prove exactly that, by commissioning Europe’s largest Concentrated Solar Thermal Platform and Thermal Storage Unit. The clean energy transition is the only path to a sustainable future. Investments in innovative renewable energy sources, like this project in Turnhout, will lower our carbon output and have a positive effect on climate change. I am proud to see the active involvement and enthusiastic community support from local Turnhout residents, brought together by Campina Energie. Only by working together will we tackle the climate crisis,” said Tinne Van der Straeten, Belgian Minister of Energy.

“We have big ambitions to tackle climate change and achieve net zero by 2050. To meet these goals, we will look across our industrial processes and identify opportunities to implement new technologies that decarbonize and reduce our reliance on fossil fuels. The successful commissioning of the project in Turnhout is a big step forward in our sustainability plans,” says Mariana Rodriguez, general manager, Avery Dennison Performance Tapes, Europe.

Jef Van Eyck, chairman of energy cooperation Campina Energie, reaffirmed the community group’s enthusiasm for the renewable energy project. “Since 2017, we have worked with Avery Dennison to produce wind energy. We are proud to cooperate again by supporting this renewable energy project. These kinds of projects, implemented with different partners, help the Kempen region towards its goal to become climate-neutral, reduce reliance on expensive, imported energy, and strengthen our economy. And what’s even more important: Campina Energie brings citizens together to be part of these projects and work on the necessary energy transition.”

Together with the local Turnhout community, Avery Dennison also plans to have sheep graze the fields and grass beyond the mirror installation. The sheep replace lawn mowers and support biodiversity on site. This burgeoning practice known as ‘agrivoltaics,’ allows for dual use of agriculture and PV installations at the same site, so both industries can use the same ground. The program causes no harm to the animals.
