There seems to be a general push against hydrogen electric transport recently. I agree that it isn’t suitable for small-scale transport, such as cars or even busses, but I do think there is a use-case for large transport.
Ultimately the problem comes how do we get the electricity from the generator to the vehicle where it needs to be. Obviously batteries are more efficient, but they come with their own problems. They weigh a lot, which damages infrastructure, they require rare metals, they have a maximum capacity per unit weight.
Of course they have advantages, but I think as the vehicle gets larger, and the charging time requirements drastically increase, I think there comes a point where hydrogen electric systems are worth looking at. Trains and shipping being the main ones, and potentially trucks.
Of course, if the hydrogen is not generated cleanly then it’s moot, but the same is true for pure electric systems as well.
Ultimately, I would like to see renewable generation that turns excess power into hydrogen for a train and coastal shipping fleet.
