Hydrogen Fuel Cells are key to reach zero emission in heavy duty transportation

  • Hydrogen is a high energy carrier
  • Hydrogen can be transported: it doesn’t need to be produced on-site
  • Heavy duty vehicles use compressed hydrogen at 350 bars: this is a standard used between buses and truck manufacturers, which means that the same fuel can serve multiple types of vehicles (a lot like diesel today)
  • It takes about 10 min to refuel a hydrogen fuel cell bus
  • Hydrogen can be produced through electrolysis, which is essentially breaking water atoms into H2 and O. Provided that the electricity supplying the electrolysis comes from a clean source, your emissions are limited.
