Traditional biofuels production is limited by the small amount of solar energy plants convert by photosynthesis into plant material that is readily processed into fuels and by inefficient fuel conversion techniques. New robust, farm-ready crops are needed that produce more easily convertible fuel precursors per acre at dramatically lower costs. If successful, advanced biofuels would offer a renewable alternative to petroleum-based fuels that produces nearly zero net greenhouse gas emissions. Biofuels must be produced at close to half their current cost to make them cost-competitive with petroleum-based fuels.
Project Innovation + Advantages:
LBNL is modifying tobacco to enable it to directly produce fuel molecules in its leaves for use as a biofuel. Tobacco is a good crop for biofuels production because it is an outstanding biomass crop, has a long history of cultivation, does not compete with the national food supply, and is highly responsive to genetic manipulation. LBNL will incorporate traits for hydrocarbon biosynthesis from cyanobacteria and algae, and enhance light utilization and carbon uptake in tobacco, improving the efficiency of photosynthesis so more fuel can be produced in the leaves. The tobacco-generated biofuels can be processed for gasoline, jet fuel or diesel alternatives. LBNL is also working to optimize methods for planting, cultivating and harvesting tobacco to increase biomass production several-fold over the level of traditional growing techniques.
If successful, LBNL's project would genetically engineer tobacco to enable it to produce oil directly from its leaves. This could enable large scale production of oils, which could eventually begin to replace petroleum-based fuels.
The transportation sector accounts for nearly all of our petroleum imports. Providing an advanced biofuels alternative to petroleum will allow the U.S. to reduce these imports, improving our energy independence.
The U.S. imports nearly $1 billion in petroleum each day, accounting for the single largest factor in our trade balance with the rest of the world. Biofuels can be produced domestically, allowing us to keep more dollars at home.
More than 25% of all greenhouse gas emissions in the U.S. come from the transportation sector. Because plants naturally absorb carbon dioxide as they grow, the level of greenhouse gas emissions from biofuels is less than half that of petroleum fuels.
