Looking around, I see where some refinery conversions are supposedly under way to make biofuels, most of them to make biodiesel. I see where Shell also plans to make some biojet.
What I don't see is where any of them involve any plans to make any biofuel to replace gasoline.
Or to replace natural gas, come to think of it.
There's a difference in terminology here that I think is relevant. There are 'sustainable' or 'renewable' fuels. Things like corn or sugar based Ethanol would be considered sustainable. There's really no limit to the amount we can produce, we just need to grow more corn - for example.
And then there are the so-called 'carbon-neutral' fuels. To me, Ethanol is not carbon-neutral. One needs to expend large amounts of carbon to produce the fuel and then even more when it's consumed. But something like methane capture from livestock feed yards used to produce say something like methanol. In the first step, you're capturing carbon emission that would otherwise end up in the atmosphere, but them releasing upon combustion. So the net is zero compared to if you have not used that particular fuel.
I don't disagree with you that the major influence on what is researched and viable vs what gets deployed comes down to nothing but $$$
