Viable Alternative Energy
Favourable Characteristics
Wide Applications
Favourable Supply Dynamics
High Adaptability
“Clean” & safe
Lower smoke emission rates
Characteristics similar to LPG
Blend stock or substitute for fuel
Expanding applications
Methanol can be derived from coal, natural gas or biomass
– Abundance of coal: cost adv
Can be transported & stored like LPG
Minimal modifications to existing fuel system required

TRANSPORTATION FUEL
JANUARY 2005- JIUTAI ENRGY WAS TASKED BY CHINESE SCIENCE MINISTRY TO CARRY OUT DME AUTOMOTIVE CLEAN FUEL PROGRAM. THE PROGRAM SUCCESSFULLY CONCLUDED IN JUNE 2007.
R&D COLLABORATION WITH WEICHAI POWER, ZHONG TONG BUS, DME PUBLIC BUSES NOW OPERATING ON ROAD 19, LINYI FOR 5 YEARS WITH 200,000 KM MILEAGE. OPERATION SATISFACTORY.
WITH 7 YEARS EXPERIENCE OF OPERATING MORE THAN 10 DME BUSES FOR EMPLOYEES, ACCUMULATED WEALTH OF PRACTICAL DATA AND KNOWHOW, ON 7 DECEMBER 2008, JIUTAI CHEMICAL WAS AWARDED “MODEL COMPANY FOR ETHER TRANSPORTATION CLEAN FUEL” BY ETHER TRANSPORTATION CLEAN FUEL ASSOCIATION.
