But the fuels are 100% sustainable going forward. It’s made from agricultural waste, no prime growth ingredients allowed, and it’s a “drop in” fuel, compatible with modern internal combustion engines, so not like E85 which requires special parts. At scale the fuel F1 will be using (and F2 already is using) can be put in any car, so it’s a path forward to a sustainable fuel for everyone. Complete petrol replacement
And since F1 cars could run on gas from you local petrol station, though not as well, that’s a pretty big deal. They aren’t using jet fuel, or anything extraordinarily exotic. Just precisely tuned normal gasoline, and next year it’ll be precisely tuned vegetable gasoline
