HYBRIDS AND HYDROGEN: CURES FOR THE GAS PUMP BLUES?
Alternative Fuels Researcher Says Alcohols, Hydrogen May Have Automotive Future
LUBBOCK -- “Hydrogen has a future, but it will be a few years before hydrogen production,
distribution and on-board storage are really available. Hydrogen fueled engines will
be practical much sooner than fuel cells.” Timothy Maxwell, professor of mechanical
engineering, Texas Tech University’s Department of Mechanical Engineering.
Rising costs at the gas pump could prime consumers for new fuel alternatives, Maxwell
said. Hybrid vehicle sales in the United States are growing as a wider variety of
models attract consumers.
Hybrid electric vehicles with diesel engines could be even more efficient than hybrids
fueled by gasoline, Maxwell said, though he noted that they are more expensive.
Other fuels like ethanol, methanol and mixtures of those alcohols with gasoline could
increase in popularity, he said, while options like liquid petroleum gas or propane
likely will see more use by farmers and ranchers.
Researchers in Texas Tech’s Mechanical Engineering Department have been involved in
alternative fuels research since 1988, when they were first awarded a 1988 Chevrolet
Corsica to be converted to operate using a combination of methanol and gasoline. Since
then, the department has been involved in vehicle design projects and research programs
using methanol, ethanol, natural gas, hydrogen and hybrid electric drive trains. They
have cold-started methanol engines, operated engines using enriched oxygen and studied
the long-term effects of engine operation using pure methanol.
Maxwell is the author of “Alternative Fuels: Emissions, Economics and Performance.”
During his 30-year-career, he has worked with automobile manufacturers including Ford,
General Motors and Chrysler.
