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
This isn't a fuel cell. It's an ICE motor.
This is why Toyota and other manufacturers are still working on hydrogen. The ICE motor to run these is pretty much the same as current petroleum based ICE motors. Until batteries can charge in 5mins and travel more than 100 miles under load, then hydrogen is the way.
