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.
“Radically improving energy efficiency will reduce the need for investment in energy infrastructure, cut fuel costs, increase competitiveness, lessen exposure to fuel price volatility, increase energy affordability for low-income households and cut local and global pollutants improving consumer welfare” Source OECD Energy report, 2014

The quality of the hydrogen injected into fuel cells directly influences fuel cell performance. However, regardless of how hydrogen is produced (by water electrolysis or cracking biomass or natural gas), providing a guarantee of its purity costs money. Liten, a CEA Tech institute, completed a series of tests to measure the influence of several impurities on fuel cells in order to determine the optimal compromise between cost and performance.
The pollutants studied (NH3, HCl, and C4Cl4F6) were voluntarily introduced separately and in tiny amounts into pure hydrogen. The performance of fuel cells using the "polluted" hydrogen was tested on equipment developed and validated for this purpose. For example, appropriate measures were taken to prevent the test benches' piping from adsorbing substances so as not to skew the results. The impact of the pollutants on fuel cell lifespans was measured by extrapolating the results obtained from 900 hours of testing. The membrane electrode assemblies were autopsied so that the impact of the various pollutants on the degradation of the materials could be studied.
The results obtained were used to make recommendations on the acceptable amounts of each pollutant studied, and will serve as baselines for future versions of hydrogen quality standards, which will be drawn up with input from international hydrogen stakeholders (hydrogen producers, filling stations, automotive manufacturers).
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
