Why hydrogen? Why not electric at this point?
there are seroius longevity concerns with Lithium batteries. if you just fill the car up with combustible gas, there's no battery that is expensive to replace every 10-20 years. australia could very well be one of the best countries tp deploy this technology.
These concers exist for Hydrogen too. While the Hydrogen tanks can last a longe time, the catalyst in the Fuel cell degrades, like the electrodes of batteries do. That means that the fuel cell needs to be replaced as well after some time. In addtition to that, fuel cell vehicles need batteries as well, since the fuel cell is slow to respond to load changes. These smaller batteries are stressed heavily in stop and go traffic and will need to be replaced a lot more often than Ev batteries.
I think they are talking about using hydrogen as the fuel for an internal combustion engine, not fuel cells
