A hydrogen-powered plane took
to the air in Germany in 2009.
means it does not use
a motor while in the
air. Some day, fuel cell
technology may be
used to power bigger
planes with engines
that can carry hundreds
of passengers.
Even though there are many challenges to meet, hydrogen
fuel presents an excellent choice as an energy resource for the
future. As of 2008, more than 40 U.S. states had projects under
way, in the U.S. Department of Energy's Hydrogen Program,
focusing on hydrogen and fuel cell research and development.
Researchers believe that hydrogen is one of the cleanest fuels
available. This is
very important
in a world that
needs clean
sources of power.
A scientist checks on a device
for producing hydrogen using
sunlight and water.
