Liten is a major European research institute and a driving force behind the development of the sustainable energy technologies of the future. The institute is spearheading the EU’s efforts to limit dependency on fossil fuels and reduce greenhouse gas emissions in three key areas: renewable energy, energy efficiency/storage and development of materials.
Our platforms, sophisticated tools for industry & the scientific/technical infrastructure/expertise to overcome technological hurdles
Liten's research teams work across a vast portfolio of renewable energy technologies. Cutting-edge photovoltaic technologies are developed at INES, the French National centre for solar research and R&D with Hydrogen and Biomass activities being managed from the LITEN's main site in Grenoble, Rhone-Alpes.

Nanostructured surfaces: surface-structuring know-how for a broad range of industrial applications
Liten’s nanostructured surfaces research focuses on three major topics:
Our researchers are looking at how moving engine parts fit together and how their surfaces are structured to reduce friction for greater fuel efficiency and, in the process, limit exhaust gas emissions. Our research encompasses all aspects, including using catalysts to treat exhaust gas. Liten research is behind the new Euro 7 and Euro 8 catalytic exhaust pipes that will be introduced onto the market by 2018–2020. We have a decade of experience researching this topic.Liten’s know-how is also driving advances in other areas, such as plasma-photocatalysis to treat air in the rail and airline industries. The traditional active charcoal filters used on board aircraft, for example, could one day be replaced by catalytic converters that would treat a much broader range of harmful emissions, with the added benefit of regeneration capacities not offered by traditional filters. Filter maintenance would be greatly reduced, and planes would be grounded less. Other promising avenues include treating air inside the passenger compartments of cars in large, densely-populated urban areas and treating air in confined spaces like submarines.
Graphene and carbon, both very lightweight materials, offer a unique combination of excellent electrical, technical, and mechanical properties. When used to make nanotubes, which are then assembled at a macroscopic scale, the materials’ properties are maintained. The benefits are clear for uses like cabling, where graphene and carbon nanotubes can replace aluminum and copper, both of which are expensive to extract, manufacture, and recycle. These materials save on resources and weight, a critical factor for the air transportation industry, for example. An Airbus A380 contains between 5 and 5.5 tons of cable; the equivalent in carbon nanotubes would weigh in at just 100 kg. This drastic reduction in weight would be a source of substantial energy savings and would make recycling much less costly.Liten is currently producing carbon nanotube cables from several hundreds of meters up to a kilometer in length. These cables would be suitable for all minor aircraft cable networks; broader use will be feasible within five to ten years.
Liten’s research in this area cuts across the research described above, leveraging our scientists’ knowledge of surface structuring and treatment to meet manufacturers’ needs for materials with exceptional electrical or thermal conductivity or mechanical properties.We have a wide range of resources to structure the surfaces of all types of materials (steel, aluminum, ceramics, plastics, and textiles, for example). Our processes, carried out at the micrometric and nanometric scales, have the capacity to amplify a material’s chemical and physical properties. Some of these processes are ready for immediate industrial rollout; others—like solutions to limit contamination in air conditioning systems and cooling towers—will require substantial additional R&D before they can be scaled up. Our nanostructured thin-layer deposition processes are already showing promise as a future solution to this public health issue.Our researchers have developed:
