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.

Fuel cells: an effective energy source for transportation
Liten has been developing low-temperature fuel cells for transportation since the early 1990s. Proton exchange membrane fuel cells (PEMFCs) are currently the most promising solution, offering several advantages. PEMFCs are clean, greenhouse-gas-emission free, can be installed right on board a vehicle and offer excellent yields, at around 50%. And, because PEMFCs offer high specific energy, they could help give electric vehicles ranges similar to those of combustion-engine-powered cars. Fuel cells also present the advantage of being relatively fast and easy to charge and do not require a major shift from existing driver habits. Drivers simply go to a hydrogen filling station, where it takes just three minutes to fill a 700 bar tank. Given the benefits, it is no wonder that car manufacturers around the globe are keeping a close eye on fuel-cell technology. Toyota introduced its Mirai in 2014–2015, and some 600 of the fuel-cell-powered sedans have been manufactured to date. Liten is the only research institute to cover the entire fuel-cell value chain, from materials to demonstrator system design to manufacturing processes. In recent years our research has turned to overall system performance, specific energy, energy density, and, especially, the electrochemical performance of the membrane-electrode assembly (MEA). Our researchers use multi-scale modelling and a wide range of characterization techniques. Some are specific to fuel-cell research. These include test benches for new materials, power battery testing, and demonstrator fuel-cell testing in actual operating conditions. Other resources, like the nanocharacterization platform and large scientific instruments, are common to other CEA research programs. We also benefit from the CEA fuel-cell platform, a pilot fuel-cell-core manufacturing facility with a capacity of up to several hundred MEAs that can be used to investigate and improve manufacturing processes, scale-up, and reproducibility. Finally, we are monitoring several fuel-cell systems in actual use (either in real-world conditions or in controlled environments), gaining insights that will lead to better system architectures and innovative new operating strategies.Our efforts to enhance fuel-cell performance are rounded out by research to reduce fuel-cell system costs, another key factor in current fuel-cell development work. Specifically, our researchers are looking at how to reduce the amount of precious metals required to make fuel cells and how to increase fuel-cell lifespans, with the target of moving from the current state of the art of 2,500 hours to 6,000 hours. These advances will help fuel widespread adoption, especially in the field of electric vehicles.
