For longer range motorcycling, this is probably the way rather than trying to haul around a sufficiently capacious battery bank.
What remains to be seen is if anyone manages to produce a non-stupid way of producing enough hydrogen, and packaging and distributing the result in such a way that anyone in a position to take advantage of it can actually buy it. (The current methodology for bulk hydrogen production is still fossil fuel based, as far as I know.)
I mean, producing hydrogen by using electrolysis is probably the best option we have if we want to truly free ourselves from fossil fuels. You’ll run into the same issue that hydrogen cars have tho, which is that it’s expensive to run something on hydrogen compared to batteries. Even electric trucks are preferred to hydrogen trucks now due to the difference in costs, meaning that it’s unlikely that infrastructure will be rolled out that makes a hydrogen bike usable.
In the end, these kinds of bikes might be better off with a battery swapping system like seen in electric scooters.
Certain infrastructure is planned in Germany, but bikes are of course not the target.
With the planned coal phase-out 2030-2038 (early optimistic scheduled date & later pessimistic date), the government is planning gas backup plants for 25 GW capacity. All those plants are planned for natural gas now and later to be switched to hydrogen. So the natural gas pipeline network is also included with upgrades in the future, to carry hydrogen.
For years already, in the northern parts there is sometimes too much renewable energy generated, so that wind and solar generation has to be disconnected from the grid. It’s just wasted for nothing. Ideally, some those excess capacities will be used in the future to generate hydrogen. Which then can be pumped into the grid, which again can be used for gas backup plants to generate electricity.
So trucks and bikes do have a chance there, even thought the infrastructure is currently schemed on a larger scale than vehicles.
