“Existing hydrocarbon infrastructure” The fact that it exists does not mean that it’s fit for purpose. Hydrogen gas has very different material requirements, you can’t simply put it into those pipes. “If the source energy is cheap and the sold hydrogen is expensive” Except a) the energy is not cheap (nor is the equipment required to make and transport the hydrogen). And b) who is going to buy this expensive hydrogen when they could instead use a cheaper alternative which is much more efficient (direct electricity cation)?
