Biofuels aren't worse than fossil fuels but they surprisingly aren't much better. You can make renewable e-fuels with just renewable power and recaptured CO2, but they take an obscene amount of energy and then the ICE turns most of what all that energy produced into waste heat.
Hydrogen is a fossil fuel industry distraction, it offers the best selection of the worst downsides: An expensive and currently mostly fossil-sourced fuel you need to get at a station like gas/diesel, relatively long refuel times and short range in a vehicle with a higher up-front cost and weight like an EV, and a fuel that is only available at a small handful of stations, needs to be stored at immense pressures, escapes through solids and embrittles steel on the way out, and burns with an invisible flame like only hydrogen can offer.
We won't be able to get rid of liquid hydrocarbon fuels completely any time soon but we can make their uses a small enough fraction of what they are today that they're no longer a major source of fossil CO2 emissions and these oddball "fucking around in the margins" solutions can fulfill a decent fraction of the demand.
