Power-to-X, ie electrolysis seems a much better path for CO2 neutral flight, and norway is ideal for that as well.
The better name would be "Green" or "Eco-friendly" flight, because "CO2 zero" or "CO2 neutral" is impossible for us yet.
> Rivan’s RNG (renewable natural gas) generator combines 3 core technologies:
1. A calcium-looping DAC system (CO2)
2. An alkaline water electrolyser (H2)
3. A sabatier reactor (CH4)
To produce 99.9% pure synthetic natural gas, which acts as a carbon-neutral drop-in replacement for fossil alternatives.
