There s got to be a mixture EVs. There are 300million personal use cars in Europe alone. In US probably similar numbers then you factor in China, Japan, Australia, New Zealand etc. There are a lot of cars.
On CO2 g/km, the chap at Toyota running the Swindon trial reckons over life time of a Fuel Cell EV it is around 65g/km assuming hydrogen is derived from renewable when compared with 125g/km for battery EV. Due to the embodied carbon in producing and disposing batteries. Also recycling lithium is not easy either from I have read. Which is why there s very little economy in recycling at the moment. But when vehicle battery enter the frame it may be different as there are a lot more metal to be sourced from a single bank of batteries than iPhone for instance.
On fuel cell side, they ah e developed fuel cell that can work off waste fuel from a gas turbine which can generate hydrogen as well as capture carbon but the tech can be used in any waste fuel situation such as steel works . It’s pretty impressive but again not heard about...it is a promising tech until we somehow find a way to produce unlimited cheap energy....
