  As NREL, state and federal agen-
cies, and industry continue their
demonstration and evaluation of
methanol, answers will be found to
break down barriers to its use as an
alternative transportation fuel. As
demand increases and feedstock
and conversion research advances,
methanol produced from biomass
may fuel a steadily growing percent-
age of our vehicles into the next
century.

Environmental Effects
Produced for the
Methanol fuels produced from
biomass feedstocks can reduce net
greenhouse gases from automobile
emissions. The biomass feedstock
takes up carbon dioxide during
growth-- in amounts equal to those

nitrogen oxide emissions. Its
greater tolerance to lean combus-
tion (higher air-to-fuel) ratios results
in generally lower overall emissions
and higher energy efficiency.
In addition, production of methanol
from biomass can turn municipal,
industrial, agricultural, and forestry
wastes into energy resources. Culti-
vation of dedicated energy crops for
methanol production can provide
year-round ground cover for erosion-
prone croplands.
