| Researchers
at Missouri University of Science and Technology are developing a portable,
hydrogen-generating power system to power everything from laptops to communications
gear for soldiers in the battlefield.
The system transforms jet fuel
into hydrogen and will relive soldiers from having to carry heavy loads
of batteries. Individual soldiers carry between 20 to 40 pounds of batteries
on standard four-day missions. The batteries power soldiers’ personal portable
electronics, such as GPS systems and night-vision goggles.
“The military, for very good
reasons, can operate all of its hardware -- from tanks to naval ships --
off of one single fuel, JP-8, which is similar to civilian aviation fuel,”
says Jonathan Wenzel, assistant research engineer in chemical and biological
engineering at Missouri S&T. “Jet fuel, like gasoline, is a mixture
of hundreds of different chemicals that contain hydrogen and carbon, called
hydrocarbons.”
The system works by reacting
jet fuel with water to produce hydrogen. Small amounts of carbon dioxide,
methane, carbon monoxide and ethane are also released during the process.
When the power unit is in the
battlefield, the need for soldiers to carry heavy, cumbersome batteries
could be eliminated, as convoys already carry fuel for their vehicles.
The single reliance on jet fuel provides logistical benefits, as the military
wouldn’t have to stockpile batteries and distribute them on the battlefield.
The quiet, odor-free process also doesn’t produce a thermal signature with
its exhaust, unlike the jet fuel and diesel electric generators that are
currently used in the field.
“Think about how loud and smelly
the generators are that many people bought in the last ice storm,” says
Wenzel, who is working under the direction of Dr. KB Lee, professor of
chemical and biological engineering at Missouri S&T.
A small scalable unit could be
built to produce a small amount of hydrogen or increased to provide enough
energy to power an entire navy ship. In addition, the system could generate
sanitary drinking water with the addition of a fuel cell.
The project is supported by the
U.S. Army and DRS-TSI, which provides information technology solutions
to government clients.
