Which is all fine, but then let's not pretend that it is relevant, and just accept F1 is a show. And let's also be honest that an overzealous drive for synfuels (fueled by pretensions of societal relevance) may actually, on the larger scale of things, do more harm than good.
Most of the topics you address have been reacted to in detail by Wesley and JAF, and I largely stand by their contributions - so I will not respond to every point in detail. But what is important to realize is that synfuels have major limitations. In essence, synfuels are batteries, too - they're chemical means of storing (sustainable) energy. They have advantages (energy density, transportability as liquid), and drawbacks: mainly, involving many energy-intensive production steps, which means the windmill-to-wheel (or other means of power generation) efficiency is quite a bit lower for synfuels (and hydrogen) than for batteries. The 'brief' by the Royal Society shows that quite well: https://royalsociety.org/-/media/policy ... iefing.pdf
BEVs have a 65% efficiency according to this analysis, syn-diesel... 13%. So, you need about 5x the amount of renewable energy to get the same power on the road when you're using synfuels compared to batteries. Which means you can drive much fewer cars on the same amount of energy, or alternatively, you need much more renewable power generation to drive the same amount of cars (maybe not 5x, because fuel cars can be lighter than battery cars & such, but still).
But we don't magically have more renewable power - the fact that something is reliable doesn't make it limitless, and even if solar energy is abundant - harvest of it is sorely limited, and will be for decades. If you are investing substantial amounts in the production of synfuels while renewable energy overall is limited, you are preventing that energy from being used in other, more efficient applications. In other words, you may be 'greening up' your scope - but you are blocking other markets from greening up more, and slowing down the overall transition. That is not to say there is no market for synfuels; their advantages may outweigh their disadvantages in certain markets, such as long-haul heavy traffic and aviation, where the energy density and charging rate of batteries are too much of an issue. That's fine, but use them where they make sense. Don't try to turn them into a magic bullet that they are not. And the same applies to batteries, of course. They are not a magic bullet either, and I am highly sceptical of electric flight at any serious scale. Overall, my bet is on batteries for commute, hydrogen/methanol fuel cells (and perhaps ammonia) for long-haul road transport and shipping, and synfuel for aviation. If you follow the over-optimistic 'techblogs' it may seem like we're going for synfuel road transport and electric aviation - if that materialises, we did something really really wrong in terms of energy requirement. And after all, the most green energy technology is the energy you do not need to generate.
The 'current synfuel' you are referring to (E85 and such) are mostly 1st generation biofuels - competition with food, and requiring huge swaths of land to be cleared for production. I am not fully against them as they can serve a buffer function (in the sense that you can valorize overproduced food, provided you always prioritise usage as food in times of shortage), but they are not feasible for scale-up towards the full, worldwide fuel market. There is insufficient land to do so. There has been some fuzz around 2nd generation biofuels (using farmwaste instead of edible material) some decade ago, but there is a reason that all companies that tried to bring that to market failed - they're expensive (cannot compete with current oil price) and provide little return on energy. But even if we overcome those challenges, there is not enough biomass to go around. Systems analysis indicates that at best we may produce enough biofuel for aviation, maybe some shipping, but no more than that. And again, in that case you're best off serving the markets that have no alternative - not the market where there is a much higher efficiency alternative available.
For the rest, it may be good to be aware that this discussion was essentially done before, in viewtopic.php?f=4&t=29554
It didn't really go anywhere, but if you have some interesting new takes, it may be best to move there instead of the silly season.
