Top Biofuel Crops

You know, the mark of an article or perspective on renewables technology that knows what it's talking about is that it goes into the $ economics or cost curve of the thing. $/MMBtu, $/ton eCO2 etc. You want to know at what price the proposed new fuel will displace certain tranches of existing fuel sources that people/industries choose to use.

This article is 1-2 steps above clickbait (as is, correct me if I'm wrong, the website itself) where someone was paid $50 to do internet research and write it.

Maybe more informed people can talk about it here anyway.

The photosynthesis in sugarcane is about twice as efficient as any other plant. In addition, the sugar is easily extracted (unlike eg. maize), and a large percentage of the crop mass (also unlike maize).

IMO a big chunk of what killed biofuels was the wrong choice of crop.

Biofuel for land vehicles is largely dead, or rather limited to legacy systems (Brazil etc). Whatever EVs can't do (if anything) will likely be taken up by hydrogen.

Biofuel for airplanes however will probably be around for a while. Unlike cars, airplanes are usually built to last for decades. It might be possible to fly planes fuelled by hydrogen or ammonia, but many of the planes currently flying today should still be flying in 2050 -- not necessarily a bad thing because building an airplane isn't exactly low-impact. Synthesizing jet fuel from plant matter is probably easier than starting from "scratch" (syngas).

What about barley/oats? I read on a swedish website for ethanol production that it's a formidable biofuel crop, if not only because it can grow even on the worst suited kinds of lands.

BTW, I wanted to get into the biofuel business, but it only then occurred to me that ethanol production is equivalent to making distilled alcohol, which is a no-no for us muslims.

I'd have thought algaculture might have made the list, but maybe it's not great for fuel production?
