A collaboration between four Belgian research institutions has been transformed into an energy research, development and innovation hub in the Flanders region. The project Towards a Sustainable Energy Supply in Cities, has financed state-of-the-art facilities, a large-scale living lab and research for energy technologies and services at the EnergyVille site, at the Thor Park industry incubator. Working with local communities and businesses, the hub has developed innovations and shared knowledge to accelerate Europe’s transition to a carbon-free society.
