This raises the question of how to get the energy to where it is needed.

Applications of green hydrogen

Mobility

H2 bus
  • a) the cost of the fuel cells which recombine the hydrogen with oxygen to give water and electrical energy, and
  • b) finding areas of application in which investments into infrastructures are required at critical locations.
Hydrogen fuel cell truck verification to start in spring 2022
Hydrogen ‘plane pods’ concept by Airbus

And apart from mobility?

Conclusion

Energy from renewable sources is the primary bottleneck on the way to decarbonisation.
