You’re completely ignoring the fact that it takes 3 to 5 times as much energy to actually drive a hydrogen car, because of the (in)efficiencies of the hydrogen production, supply and consumption chains.
And given that the driving of a car is what consumes the most energy in its lifetime, the much higher efficiency of a BEV ‘pays off’ the higher production costs, both monetarily and ecologically.
Don’t worry.
Trig is not hard ☺️
Compared to what you’re also gonna learn 🤣
