In 2011, the US consumed 134bn gallons (507bn litres) of gasoline, but “with our technology, just 700m pounds [317,500 tonnes] of biomass would be enough to replace the whole yearly [gasoline] production,” says Zhang. The last official assessments estimate the availability of crop residues for biomass in the US to be about 157m tonnes per year.
