A new pipeline at the National Renewable Energy Lab is analysing 1,000 samples of biomass at a time, finding which one, combined with the right enzyme, most eagerly gives up its sugars to be converted into biofuel.
The deadline is just 12 years away to turn switch grass, poplar trees or other renewable biomass into 36 billion gallons of fuel for cars and trucks.
The Energy Independence and Security Act requires that the United States produce 36 billion gallons of biofuel by 2022. That would comprise one-third of the annual transportation fuels budget, now dominated by gasoline.
