Let's sort the outright Bullxxx from the facts.
In OZ there are 3 different plugs for EV's, CCS1, CCS2, ChaDeMo. CCS2 is the adopted standard, but some legacy support for the others still need to be supported, conversion kits are available however. How many handles are there at the standard service station ATM, at least 4 sometimes 5, sometimes 6 (Diesel, Adblue, unleaded, premium, 98, Gas)
The conversion of hydrogen to electricity and then back to electricity is around 50% each way hence hydrogen powered vehicles are around 25% efficient. Way better then ICE at around 15%, but not a patch on EV's at 80-90%. And thats efficiency from well to wheels.
The majority of EV owners simply plug their car in at home and charge overnight, or for those of us retired folks, during the day while the sun is shining. It's only a lack of infrastructure that prevents more of this at parking buildings and workplaces for those who work during the day.
And, before anyone jumps on their high horse about do we have enough electricity to power all this, just be aware that the electricity generator regulator (AEMO) regularly curtails output from solar and wind farms because we cant use their output and our existing coal and gas units are unable to respond quickly enough to changes in output requirement.
How many riders swing into a servo at 400km, fill up, and swing straight out for another 400km's. 90% (a guess) of riders do a couple of hours at a stretch between coffee or meal breaks, easily enough time to add several hundred kilometres of charge to your EV.
Their are limitations on raw materials for batteries ATM, but there is rapid development on changing materials and processes to reduce or remove difficult materials like Cobalt, copper etc.
In addition, we have almost limitless ability to produce electricity in Australia. Wind, Solar, Gas, Coal, Wave energy, Hydro..... Yet we still prefer to import oil/petrol/diesel.
