> Blue : produced by steam reforming of methane with carbon capture and storage in underground caves (still under feasability study)
> Green : produced by water electrolysis with electricity from renewable energy (hydraulic, wind, photovoltaic): no greenhouse gas emissions in the production of hydrogen (strong growth)



Atawey hydrogen technology

How does an hydrogen station work?Atawey hydrogen stations can produce on-site green hydrogen from renewable electricity and water. How does a hydrogen station work? It is made up of:
- an electrolyser, which dissociates the hydrogen and oxygen atoms of water by chemical reaction using electricity
- a compressor and gas bottles to be able to store as much hydrogen as possible
- a 350 or 700 bar supply pipe to recharge fuel cell cars

electrolysis of water to produce green hydrogenOur patented water electrolysis technology, innovative by its high environmental performance, is embedded in our charging stations, so that we produce (green) hydrogen locally, from (renewable) electricity and water.

The hydrogen car will do the opposite, transforming hydrogen into electric current using a fuel cell. The generated current will provide energy for the electric motor.

The Atawey range for hydrogen mobility

Located in the heart of the Bourget du Lac technopole (France), Atawey manufactures and markets green hydrogen refueling stations.

Our range of products named “Atawheel®” allows the refueling of small to medium fleets of all types of vehicles, such as bicycles, utility vehicles or sedans, but also heavy vehicles, handling equipment and other special vehicles.

Our stations are perfectly suited to initiate hydrogen projects for fleets of up to fifty cars and a few heavy vehicles, or to build a network in the regions, in France or in Europe. Atawey hydrogen stations can be quickly installed and they comply with the EU regulations. The Atawey offer is aimed at territories, cities or private companies and adapts to changing uses.

There are two different sizes of Atawey station:

- Compact, easy to install and move, for small fleets of light vehicles and bicycles
- Versatile, scalable to adapt to the growing needs of fleets of up to 50 light vehicles and a few heavy vehicles

The 2 sizes of Atawey hydrogen stations: compact and intermediate

Atawey hydrogen charging stations come in two types:

- autonomous stations, producing green hydrogen on site by electrolysis of water connected directly to renewable energies or to the network: H2Spring
- dispenser stations where hydrogen is supplied by external logistics: H2Flow

The 2 types of Atawey stations: production or dispenser
There are 3 delivered pressure options: 300, 350 and 700 bars to adapt to all types of vehicles

The 3 pressures delivered by Atawey hydrogen stations


Atawey has a diverse range with three offers:

- Soft mobility: Hydrogen bike stations for 150 km of autonomy
- Compact stations for carrying out pilot projects or for small fleets: up to 75,000km per year
- Scalable and multi-pressure stations which can supply hydrogen fuel to about fifty light vehicles as well as some heavy vehicles

The offer includes: A fleet of electrically assisted hydrogen bikes + refueling stations + maintenance and services for long-term use of the station and the bikes. It is aimed at public services, tourism professionals, businesses and administrations for employees’ commute and easier travelling in urban areas.

Atawey hydrogen bike station at Saint-Lô

Case study : Saint-Lô - Activating energies

To engage citizens with soft mobility, the city of Saint-Lô decided to install an Atawey hydrogen charging station for bicycles and together with 10 Pragma hydrogen bicycles. The hospital staff were the firsts to use the hydrogen bikes, followed by high-school teenagers. This demonstration of sustainable mobility generated positive engagement from all, as “the fast refuel of the bike convinced the staff”.

Case study : IOC in Lausanne - For a sustainable mobility

For the Lausanne staff mobility, the International Olympic Committee acquired 8 Toyota Miraï and an Atawey hydrogen refueling station. To promote sustainable mobility, the IOC has chosen the hydrogen technology: zero emissions and greater autonomy range than battery-powered cars. The fleet thus participates in inspiring a green dynamic in the region, with the IOC among the pionneers.
"Driving around the area, nearly every day, I get stopped and asked questions about the station, our vehicles and the technology behind it." José Diamantino, IOC Fleet Manager.

Hydrogen Station IOC Lausanne Atawey"Besides reducing our carbon emissions, we saw the hydrogen vehicles and fuelling station as a way to advance a discussion about sustainability and strengthen the role of the Olympic Movement to inspire positive change” Marie Sallois, Director of Organizational Development and Sustainable Development at the IOC

For larger fleets or to build a network: The multi-purpose hydrogen station

Hdyrogen station Atawey ZEV ChambéryOur multipurpose station is designed for intense use of the fleet, light or heavy. It delivers a pressure of 350 and 700bar, in accordance with vehicle manufacturers' standards and has a supply capacity compatible with heavy vehicles. A 6kg refuel for a light vehicle will allow you to drive 600km while a 12m bus tank volume is around 30kg for a distance range of 300km.
These stations facilitate the use and adoption of hydrogen vehicles. Building a network of hydrogen stations reduces the access time to stations while increasing the number of refueling options for users during their activities and trips. In addition, a web of hydrogen stations increases the resilience of the network and the assurance of at least one station available in the region.

Case study : ZEV - Zero Emission Valley

To be the first zero-emission territory in Europe, the Auvergne Rhône Alpes region has carried out a hydrogen ecosystem project with a network of 20 charging stations and 1,000 vehicles. This project of a scope of 70 million euros over 10 years was partly funded by the European Union (10.1 million euros), the Region (15 million euros) and ADEME (14,4 million euros). The first multi-pressure station with green hydrogen production by electrolysis, installed by Atawey, was inaugurated in February 2020 and has a capacity of 50 cars. In addition to the 1,000 vehicles planned by the ZEV project, 200 vehicles will be partly financed by ADEME, including 2 buses for Grand Chambéry, 50 light vehicles and 148 vans, which will be able to refill their fuel at the station.
