Concept power units from 2030

And what about white hydrogen?
If it can simply be extracted from the ground, wouldn’t that require less energy than producing hydrogen?

Yes, and cost per kg is half.

Yes, and cost per kg is half.

So where do the problems still lie?

Extracting, storing hydrogen, liquefying it, burning hydrogen, …?

Or is white hydrogen already in liquid form?

liquid is unlikely
atm the problem (eg for F1) is that most hydrogen will still be made by methods with high carbon emissions
ie hydrogen in F1 could be seen as endorsing it as fuel even if actual F1 hydrogen was made by carbon-free methods
btw 'science' has in effect always played-down the existence of 'white' hydrogen eg to benefit the oil industry
now revelation of historic leakage of natural hydrogen at least weakens a climate case against carbon-free hydrogen fuel

we could imagine an engine with no exhaust gas (oxygen and hydrogen going in and liquid water coming out)
combustion of the hydrogen with oxygen suitably heat-diluted by managed water vapour
vapour condensing to near-vacuum would power an MGU-H equivalent
pitstop for fuel and oxidant

or more plausibly an air-breathing engine with heat dilution or managed exhaust gas recirculation
and allowing fuel carriage as ammonia and combustion as eg 90/10 ammonia/hydrogen blend
no pitstop
