How do I recharge my hydrogen bike?
Hydrogen-powered bike recharging: how does it work?
To recharge a hydrogen bike , its hydrogen tank must be filled with pressurized dihydrogen (H₂). Unlike an electric bike, which requires several hours to recharge a battery, recharging a hydrogen bike is very fast , taking only 2 to 5 minutes .
The dihydrogen used can be produced in various ways, including through a hydrogen electrolyzer , a device that breaks down water into oxygen and hydrogen using an electric current.
Where to recharge a hydrogen bike?
Refueling a hydrogen bike requires access to a hydrogen distribution station , which fills the hydrogen tank under high pressure (approximately 300 bars for bikes).
Currently, these stations are still few in number, but their number is increasing in large cities and industrial areas. Some Companies and local authorities are also investing in autonomous hydrogen generators to produce and store hydrogen on-site.
How does a hydrogen electrolyzer work to recharge a bicycle?
A hydrogen electrolyzer It allows for the local production of hydrogen using water and electricity. Several types of hydrogen electrolyzers exist, but the most common is water electrolysis , which separates hydrogen and oxygen using an electric current.
The steps in hydrogen production using an electrolyzer:
- Water (H₂O) is introduced into the hydrogen electrolyzer .
- An electric current separates water into hydrogen (H₂) and oxygen (O₂) .
- The pure hydrogen is collected and compressed to be stored in a hydrogen tank. .
- Once stored, it can be used to recharge a hydrogen bike via a suitable station.
Can you recharge a hydrogen bike at home?
To date, recharging a hydrogen bike at home remains difficult, as it requires specific infrastructure such as a hydrogen electrolyzer and a secure hydrogen tank . However, mini-hydrogen generators are under development to allow local and autonomous recharging.
What is the price of a hydrogen electrolyzer for recharging a bicycle?
The price of a hydrogen electrolyzer depends on its capacity and technology. Small models intended for domestic or professional use can cost between €5,000 and €15,000 , while industrial systems cost several hundred thousand euros.
As technology evolves, the price of hydrogen electrolyzers is expected to decrease, making green hydrogen more accessible.
How long does it take to recharge a hydrogen bike?
Recharging a hydrogen bike is much faster than recharging an electric bike. A full hydrogen tank takes between 2 and 5 minutes , allowing for almost continuous use of the bike without waiting several hours for a recharge.
What is the range of your hydrogen bike after recharging?
After a hydrogen recharge , the range varies between 100 and 150 km , depending on the bicycle model and the type of assistance used. This is comparable to, or even better than, the best electric bicycles available on the market.
What are the advantages of hydrogen refueling for a bicycle?
- Ultra-fast recharge : A full charge in just a few minutes.
- Long range : Up to 150 km on a single tank.
- Clean energy : Hydrogen only produces water as an emission.
- High lifespan : No lithium battery to recharge and replace regularly.
