Zero emission mobility based on hydrogen energy storage and water electrolysis technology

February 2019
Gallery Station avec électrolyseur 1
Gallery Station avec électrolyseur 1


An energy hub to recharge zero emissions vehicles with green hydrogen and green electricity.

Our stations with electrolyzers allow the storage of renewable energies through the hydrogen energy vector. The solution possesses an equipment that extracts hydrogen from water using electricity (water electrolysis technology). The water molecule is split into oxygen and hydrogen, the hydrogen is recovered, compressed and safely stored into vessels. This hydrogen is then used to refuel vehicles (cars, special vehicles, trucks, etc.).

Implementation Stories

Station avec électrolyseur by Atawey
Implemented by Hympulsion in Chambéry (France) in 2020

Hympulsion, a company that produces and distributes green hydrogen, wanted to be the first hydrogen valley in Europe to reduce transport carbon footprint. They built a hydrogen ecosystem with 20 hydrogen charging stations and 1,000 vehicles, a 70 M € project over 10 years that saw the first multi-pressure station with green hydrogen production by electrolysis inaugurated in February 2020, with a capacity of 50 cars.


Reduction of 145 grams of co2 / km compared to conventional cars


The environmental benefits
