Driven by the business development prospects offered by hydrogen mobility, Eiffage Energie Systèmes' Mediterranean division has embarked on building a hydrogen production and distribution station demonstrator named H2. After completing the civil engineering work in 2024, the company’s experts have finished building the station's treatment, compression, and distribution unit. The next step is to install the new-generation AEM electrolyser, which will be able to produce green hydrogen from renewable energies for completely carbon-free mobility.
‘Dihydrogen’ is an energy carrier used in its gaseous state under different pressures. Until recently, it has been produced mainly by petrochemical processes, through the steam reforming of gas. Now, however, to produce renewable hydrogen, a molecule of water (H20) can be broken down by electrolysis to extract two molecules of hydrogen (H) and one molecule of oxygen (O).
Hydrogen can be stored without deterioration, and burned without carbon emissions (in the steel industry, for example) or converted back into electricity using a process that reverses electrolysis. In this case, the yield is lower, but the reverse reaction releases only water. “Hydrogen mobility is all about vehicles fitted with a fuel cell that mixes air and hydrogen, converting the hydrogen back into electricity to drive an electric motor”, explained Alexis Brosed Ponce, Business Manager.
Electrolysis, which boasts the advantage of zero CO2 emissions (unlike steam reforming), is the technology used in the hydrogen station demonstrator our experts are currently building. It is designed for mobility and will be able to refuel all types of hydrogen-powered vehicles.
“The demonstrator is a prototype in more ways than one, and will be a first in our region. It will use a new-generation AEM electrolyser technology. This ‘made-in-France’ electrolyser is an industrial prototype developed by our partner GEN-HY. It does not use rare earths and offers higher efficiency than other electrolysers on the market", continued Alexis Brosed Ponce.
The ‘scale 1 model’ station demonstrator is to inject hydrogen into the fuel tanks of vehicles that will autonomously convert the gas back into electricity. It will take just five minutes to fill up a light vehicle with hydrogen (400-600 km range). The H2 station is to be used as a showroom, enabling experts to demonstrate their know-how in the field of hydrogen mobility.
“Demonstration by example is also a good way of teaching and training our teams in this promising technology. Initially, the station will be able to supply the three utility vehicles that our agency is about to acquire, as well as vehicles belonging to interested partners, since it should produce 50 kg of hydrogen per day, enough to supply around ten light vehicles in all,” said Alexis Brosed Ponce.
The electrolyser is to be powered by photovoltaic shades, to produce the greenest possible hydrogen. Eiffage’s vehicle fleet will soon be equipped with two hydrogen-powered vehicles. The company’s regional headquarters in Vitrolles is also equipped with 23 IRVE terminals, including three 50 kW fast-charging (DC) units.
