Observing the renewable energy transition from a European perspective

Why the Hydrogen Car Still can’t be Written Off

Mercedes has introduced its new EQXX model, an e-vehicle with a fuel cell, resulting in a range of more than 1000 km. If a global hydrogen economy would really take off, with suppliers from poor but sunny countries offering their hydrogen fuel onto the world markets, the fuel cell-based car could still become an attractive alternative to battery cars. The arguments pro:

  • Retrofitting existing fuel stations for hydrogen
  • No need for problematic lithium
  • No heavy batteries
  • Fuelling in minutes rather than hours
  • No need for millions of charging stations
  • Longer range
  • To be expected further development and ciost cutting of fuel cells in an electrolyser-driven world
  • Charging batteries is more energy efficient than the hydrogen detour, but supply is unreliable

Con-arguments: there are alternatives to lithium, charging times are rapidly being brought down too and in case of no available direct renewable electricity, a charge could be generated out of hydrogen (at an extra cost). Energy density of batteries is continuously increasing, making batteries lighter.

The battle of batteries-hydrogen has not been decided yet, perhaps the two models will coexist, like gasoline and diesel cars do.
