29/Aug./2007Background
· Portable Energy Station is useful for field server i
n no-electricity area.
· Carbon-neutral Energy is desired.
· Biodiesel Fuel is one of promising fuel for alterna
tive diesel fuel.
· There is a some problems for portable plant usin
g traditional biodiesel production process.
· We would like to suggest another technologies.

29/Aug./2007Problems in Traditional Process
· Can't esterified Free Fatty Acid
· Need large amount of water for washing
· Need many process in purification and neu
tralization of fuel and waste water
· Produce by-products such as glycerol

29/Aug./2007Conclusions
· Portable Energy Station was suggested for rural area en
ergy supply.
· STING-process is no-catalytic and no-by-product proces
s.
· STING-process was suitable for Portable Energy Station.
· Bench-scale portable plant is now developing.
· Production costs was about € 0.4/L without material cost
s and personnel costs.
