A Stadler FLIRT H2 has set a new world record that the Guinness World Records organisation has recognised by travelling 1,741.7 miles without refuelling or recharging.

The remarkable distance has been recorded as the longest distance achieved by a pilot hydrogen fuel cell electric multiple unit passenger train.

Stadler launched the FLIRT H2 at InnoTrans 2022 in Berlin.

Hydrogen fuel cells have been the next big thing for more than 50 years now.

Do you know what is holding them up?

Do you know what is holding them up?

Previously: cheap hydrocarbons and a lack of incentive to replace them.

Now: not much, the hydrogen economy is expanding.

Hydrogen storage has always been the main limit on hydrogen powered vehicles.
That and the total energy waste of producing hydrogen in the first place.

I am also aware that hydrogen fuel cells are not cold like batteries. About 25% of the energy produced is lost as heat.

From wikipedia. What is holding back hydrogen fuel cells?

• Cost. Platinum is rather expensive.
• Water evaporation can’t be too slow or too fast. And the oxygen supple has to be just right (like in a carburettor).
• Heat control. The same temperature must be maintained throughout the cell in order to prevent destruction. This is particularly challenging as the 2H2 + O2 → 2H2O reaction is highly exothermic.
• Current service life is 2,500 hours. They need to double that at least.
