Hydrogen Hoopla

[RE]

I've been wondering when this type of catalyst would be developed and made economically viable.  This provides a means to make Green Hydrogen useful as an aviation fuel as well as using atmospheric CO₂ as the carbon source, thus making a closed loop with net zero carbon emmisions, as long as the electricity is produced by renewable carbon-free methods.

Developing the right catalyst is just the first step of course, they also need to produce the hydrogen cheap enough and be able to filter the CO₂ from the atmosphere and combine it with the H to make Methane (CH₄), which would also require electrical energy input for the reaction to go forward.  Finally, they would need to use the methane to produce longer carbon chain liquid synthetic fuel, another endothermic reaction.  At the end of this process you get your Jet Fuel.  Very expensive jet fuel.  Still chump change for Elon Musk and other Private Jet owners though.

Love this design for a Hydrogen powered airplane.    Those crafty engineers may yet work out the energy density problem!
