Unlocking the structure of lignin, and feasible pathways to cellulosic conversion
Lignin, for those newer to the biofuels world, is a complex chemical compound that makes veggies, plants and wood firm, confers resistance to pests, and provides the skeletal strength to enable plants to reach up to the sun for energy.
So that’s a good thing.
If you know your Star Wars, lignin is sort of like the Force. “It surrounds us, penetrates us, and binds the galaxy together,” as Obi-Wan Kenobi observed.
One more thing: it’s highly resistant to biofuels-related enzymes, critters and magic bugs that seek to unlock the higher value in the sugars. Lignin is the single biggest technical bio-processing barrier to cellulosic biofuels. It’s exceedingly difficult to separate lignin from cellulose, and costly. After separation, lignin remains a low-value, unloved byproduct that is typically burned to generate power.
So that’s a bad thing.
As Catullus wrote in Odi et Amo
Of course, it makes you just want to sit down and talk to a plant. “You know,” a scientist might say to a bundle of switchgrass, with a voice dripping with honey, “we’d plant a lot more of you, if you could just ease back on the lignin.”
Vive La ResistanceThe quality that lignin has is recalcitrance – resistance to invasive change. We see that quality in so many aspects of the conversion of the fossil oil-based society to renewables. There’s recalcitrance, or resistance, in making flex-fuel cars, blender pumps, pipelines, and tax structures. We’re a recalcitrant species – but nothing breaks down human resistance faster than “everyday low prices” - and that’s where cellulosic recalcitrance comes in.
When people tell you that “cellulosic biofuels are five years away” (which, thankfully, they aren’t any more), that is a function of high enzyme costs. In turn, that’s a function of high enzyme loads, which in turn reflects how pesky all that lignin is in resisting the new-fangled science that attempts to convert plants into fuels.

Tom Joyce, with Dresser Wayne, a pump manufacturer told HAT that changing to flex-fuel pumps can be relatively easy, “It can cost as little as $30000.” He said the cost of conversion would be higher if a station needs additional work on underground

"Many car assemblers in Thailand will start production of flex-fuel vehicles (FFVs) with smaller engines within this year and this will offer good potential for renewable energy development," said Mr Krairit. Thailand to date has produced 700000 units

The Thune-Klobuchar bill, titled the “Ethanol Reform and Deficit Reduction Act,” would also increase tax incentives for biofuels infrastructure, allowing blender pumps to qualify for tax credits and extending the current E85 infrastructure tax credit
What is the Best E-85, Flex Fuel Conversion Kit ? - PriusChat Forums
I have three Generation 2 Prius's and I want to know if anyone has converted their Prius to E-85 ? I would like to know if the claims of increased performance and mileage are true. There are many conversion kits claiming to be the best. They claim better performance and cleaner emissions on a Prius Generation 2. What is the best flex fuel conversion kit for a Prius? What has your experience been with E-85 ? Are the conversion kits legal in the State of California ? Please reply with your experiences. THANK YOU !
