As the report posted at Green Car Congress goes on to say, actually delivering on the announced capacity expansion may be "problematic". It's not clear how the required expansion of plant oils could be achieved without severe environmental consequences. The last thing we need to see is more leveling of rain forests for palm oil plantations.

There is a lot a "pretend scalability" going on in the renewable fuels world.  Biofuel may be the best solution for long-haul aviation, and even that will constitute a significant fraction of human land use.  For every other transportation application, we should look to batteries, ammonia, and perhaps hydrogen.

Straight out of the American Petroleum Institute Marketing Playbook:


1) Promote vast potential of new "green" fuel (diesel, hydrogen)
2) Secure pledges of financing for infrastructure, development
3) Announce production will begin with only 1% renewable fuel produced from renewable sources for testing purposes, concentration to be gradually scaled up
4) Extend scaling period indefinitely: 2% by 2030, 4% by 2080, 5% by 2300, etc...you get the picture.
