Namibia is set to produce 15Mt/a of hydrogen by 2050, using about 15TWh/a of renewables, mostly wind. Germany is estimating an approximate need for 2Gt/a for its industry which is why we're also tapping e.g. Canada, they're planning on scaling to 20Mt/a by 2050. Transport will be in the form of hydrous ammonia.
Yes it's still a steep climb and the numbers are staggering but remember that this is replacing oil not just as fuel but also chemical feedstock and BASF Ludwigshafen alone consumes more resources than several small countries combined.
There's literally no alternative to that, same goes with steel smelting. Application in vehicles are going to be an insignificant blip compared to the overall hydrogen economy.
