From what research I've done, I believe BioFuels are a better stop gap than H2.
H2 is a boondoggle. I just can't find a use case that makes sense, it's poor systemic efficiency, and super-high infrastructure cost take it out of consideration. We'll still need some kind of energy dense solution for things like air travel. Biofuels can at least be carbon neutral, as you can close the carbon cycle. It will take a long way to get there of course, as the complete biofuel production cycle is also still a carbon intensive operation, but this can be fixed over time. To get to electrification quicker, I still think some hybridization is good. I'm part of this project: https://youtu.be/TuLE7CcSvRc It is a good way to get more electric cars on the road faster. The lower cost and battery size mean more cars in the fleet faster, and the same battery supply that can build one Tesla Model 3 or Y can now build more than 4 cars instead of just one. Unlike H2, this can be implemented now, and can allow biofuels to be phased in without any new tech on the car or distribution infrastructure side. Also removes the immediate requirement to build more fast charging infrastructure while still allowing long distance travel.
