As the car industry’s largest hybrid pusher, Toyota says it is better positioned to just buy credits to close the EPA gap rather than “waste” money on BEVs, its CEO said.
Green hydrogen is (potentially) a fantastic solution for transit, especially heavy transit… The jury is still out for cars but Toyota is one of the few taking that route and it’s important. Hydrogen is much lighter than batteries and refuelling is similar to petrol cars (ie quick).
The problem to be solved is leaks. More than about 5% leakage cancels out the benefits because hydrogen makes methane hang around for longer.
Hydrogen is ‘pure’ electric.
The issue with hydrogen is that it can be colours other than green. Green hydrogen is used to store the excess from renewables, and is more like a battery than a fuel. Other colours use fossil fuel, sometimes with a desperate plea to believe that they will actually capture the CO2 produced in making it.

Batteries also aren’t gonna cut the mustard for most aviation, and my understanding is that a switch to hydrogen might be the way to go there.
The basic laws of thermodynamics beg to differ…
