The Dutch municipality of Horst on the Maas and ProRail are keen to stimulate the generation of renewable energy. As partners in NEWRAIL (Noise Energy Wall Rail America in Limburg), they are testing innovations that will deliver high energy yields. This research involves mounting solar panels on both new and existing sound barrier walls. Mounting solar panels on sound barriers is a new and ground-breaking idea. That’s why more research is needed to find the best method of installation. The innovative project NEWRAIL (Noise Energy Wall Rail America in Limburg) is an initiative of ProRail in collaboration with the municipality of Horst aan de Maas, TNO (Netherlands Organisation for Applied Scientific Research), energy cooperative Reindonk Energie, and The Hague University of Applied Sciences.
