The three main reasons why hydrogen cannot help air transport to contribute to meeting the 1.5°C limit of the Paris Agreement. 💧✈️❓
A short thread. ⬇️
1. Hydrogen planes will come too late
Airbus says hydrogen aircraft will be available in 2035 - perhaps. Maybe it will take longer, maybe shorter.
But the fact is: we need to start reducing emissions today, not in 2035. And air transport must contribute to this!
2. There are no regulations to push out kerosene-powered aircraft
Airlines need reasons to switch to substitutes for fossil kerosene. But the international climate rules for aviation are shamefully weak and don’t encourage emissions reduction measures.https://stay-grounded.org/corsia-baseline-change-aviations-climate-regulation-is-broken-beyond-repair/
3. Producing hydrogen requires enormous energy amounts
We need to think carefully about where we use valuable renewable energy, because its production also has environmental impacts. An activity which is mainly used by a privileged global minority might not be the best option.
It would contribute for sure but that's not a 'solution'. It's just going down the path we are now and that leads to hell, at least for our children and after that. Planes should fly yes because people need transport but in a FAR better way than we do now.
This is green washing.
