Liquid transportation fuels from coal and biomass

"Liquid fuels from biomass and coal have the potential to reduce petroleum fuel use and CO2 emissions in the U.S. transportation sector over the next 25 years, says a new report from the National Research Council. Even with abundant resources in biomass and coal, however, substantial investments in research, development, and commercial demonstration projects will be needed to produce these alternative liquid fuels in an environmentally conscious way, and at a level that could impact U.S. dependence on imported oil."
