Context and scientific program

In the context of energy transition hydrogen plays an important role as a potential third energy carrier besides heat and electricity. Hydrogen is still produced mostly from reforming of fossil fuels but green hydrogen from electrolysis is more and more considered as a mean to valorize the irregular electricity production of renewable sources like photovoltaic and wind turbines. However, several technological challenges persist through the different steps of the hydrogen energy chain: storage, re-conversion to electricity and heat in Polymer Electrolyte Membrane (PEM) and Solid Oxide (SO) fuel cells up to the technical integration of a whole fuel cell system in an existing energy grid. In addition to the technological aspects, the reliable integration of hydrogen in an existing energy hub requires the consideration of the socio-economic background, which is crucial to ensure the acceptance of any new large scale technology by a population.

To this end, this summer school aims at providing an outline of the different scientific, technological, societal and economic challenges that have to be faced for the introduction of hydrogen in an existing local energy hub. Experts from academy and industry will share their knowledge on these various topics. The example of an Eco-District in the northern part of France will be considered as an application to illustrate the following topics:

  • Hydrogen production;
  • Hydrogen storage and compression;
  • Operation principle, performance and degradation mechanisms of PEM and SO Fuel Cells;
  • Technical integration into local energy hubs;
  • Social and economic challenges.


This summer school will take place over four days, alternating between lectures and practical exercise. In addition to these teachings, a recreational afternoon and a festive and convivial evening will be proposed.

You will find below the details of your program and the proposed sessions. In parallel with these times of practical exchange and learning, social events will also be offered, such as a rally visit of the city or a cocktail party in the city center.
