Can you absolutely guarantee me that battery electric vehicles 100% dependent on the common grid are the ultimate solution say to at least 2050?

If say fuel cells emerge as a more sustainable & practical option later next decade (particularly if China still adding 2 coal burners per month) will Govt's trash all the subsidies to BEV & EV charging stations and flip them over to fuel cell vehicles and start again?

While I obviously don't share your urgency vehicles emissions (so much more I would prioritise where we would get far more bang for buck) I certainly agree the targeted emission caps that have been LEGISLATED across EU, China & US, but firstly I don't believe BEV grid leeches are sustainable and secondly I don't believe they are the most cost efficient platform for achieving the initial emissions reductions thru to 2030, particularly with best hard estimates BEV achieving only 30% penetration 2030 leaving 70% of vehicles on the roads some form of ICE.

The positive aspect here is whatever medium/s proves out there is a high likelihood they will employ NdFeB PMM to at least some degree, and the potential rapid electrification of a portion of those 70% of ICE vehicles 2030 is a win/win.

Plus I really don't like my investments being dependent on Govt charity, as you suggest they can flipflop in a heartbeat, and I just wonder how most of the incredibly generous EU subsidies will survive the next recession when probably a third of the populace will be struggling to pay their domestic energy bills.

Show's the supplier's margin & cost is just 23%, then a bunch of taxes are loaded on proportionally, who'd want to be dependent on that for personal transport:
