The capability of methanol to replace petroleum fuels has been known for a long time. Now as the future availability of crude oil is increasingly called into question, methanol is receiving renewed interest since it can be readily made from remote natural gas and from the world’s extensive coal and biomass resources. Much work was done previously around the world to identify the proper ways to design and modify vehicles to use methanol either as a neat fuel or in blends with gasoline. Extensive fleet tests were also conducted, with the majority occurring in the U.S. where methanol vehicles were sold commercially in the early 1990s. This report presents several significant findings from that work and experience.
