EnergyVille is a collaboration between the Belgian research partners KU Leuven, VITO, imec, UHasselt in the fields of sustainable energy and intelligent energy systems. EnergyVille develops technology and knowledge to support public and private stakeholders in the transition to an energy efficient, decarbonised and sustainable urban environment. The unique complementarity of the research partners allows us to integrate the energy system value chain in its entirety, ranging from materials and components to the level of entire energy systems, business models and strategies. Our activities are clustered in eight interdisciplinary domains: solar energy, battery storage, power electronics, Power-to-Molecules, thermal systems, electrical networks, energy for buildings and districts, and energy strategy and markets.

With approximately 400 researchers and state-of-the-art research facilities, EnergyVille is a top European innovation hub in the energy field. It bundles research, development and training under one roof and collaborates closely with local, regional, national and international partners from industry as well as public authorities.

As an energy R&D innovation hub, located in the industry-oriented ecosystem of Thor Park (Genk, Belgium), EnergyVille offers an attractive environment for energy research, industrial product development and business creation. The collaboration is supported by the city of Genk, the Province of Limburg, LRM, Nuhma, POM Limburg and the European structural funds.


Imo-imomec brings together chemists, physicists and engineers to conduct multidisciplinary materials research. This with a focus on advanced material systems for a sustainable and healthy society. Our core domains: energy conversion, energy storage, sustainable materials, sensors & healthcare materials, and quantum technologies.

The Institute for Materials Research (IMO), based at the Hasselt University campus in Diepenbeek, has built a vast expertise in the field of materials science since its foundation in 1990. In 2001, a strategic alliance was established with imec, based in Leuven. Imec founded IMOMEC, an associated laboratory within the premises of IMO. As such, imo-imomec is a joint research institute where fundamental research, strategic basic research, and application-oriented research is conducted. In 2015, UHasselt/imo-imomec joined EnergyVille in Genk to carry out its energy-related research.


The Netherlands Organisation for Applied Scientific Research (TNO) is an independent research organisation. We connect people and knowledge to create innovations that boost the sustainable competitive strength of industry and well-being of society. Now and in the future. Together with our partners, we focus on the societal challenges of a safe, healthy, sustainable and digital society. This is our mission, and it is what drives us, the over 3.500 professionals at TNO, in our work every day.

Eindhoven University of Technology

TU/e profiles itself as a leading, international university specialized in engineering science & technology, with major research activities in the field of solar energy. Within the field of hybrid perovskite solar cells and in collaboration with Solliance, research is carried out at the departments of Chemical Engineering and Chemistry (Prof. R.A.J. Janssen) and Applied Physics and Science Education (Prof. M. Creatore). The research encompasses the synthesis and characterization of hybrid perovskite solar cells as well as interface engineering by atomic layer deposition.

Delft University of Technology

Delft University of Technology is the largest technical university in the Netherlands. Founded in 1842, it is among the first 20 technical university in the world for its outstanding research and teaching quality. The university has 8 faculties in all major fields of science and engineering, accommodating more than 26,000 students. The Photovoltaic Materials and Devices group (PVMD), led by prof. dr. Olindo Isabella, focuses on the development of photovoltaic technologies and applications throughout the value chain. In its research facilities, the PVMD group has established state-of-the-art processes for the fabrication of high-efficiency crystalline silicon-based solar cells. The PVMD group aims to deeper understand the solar cell device physics using advanced characterization and modelling tools and to use this knowledge for designing and fabricating advanced solar cells with higher efficiencies.
