McPhy Energy to Supply Solid Hydrogen Storage Solution to Iwatani Corporation, Japan's Market Leader

International Hydrogen & Fuel Cell Expo, TOKYO, March 1, 2011 - McPhy Energy, a leader in solid hydrogen storage technology, has
announced that the company has signed a contract with the Iwatani
Corporation, Japan's leading supplier of hydrogen in terms of market share,
to supply a 4 kilogram solid hydrogen storage solution. Because the hydrogen
is stored as a solid in the form of magnesium hydrides, the McPhy system does
not require compression. This results in an innovative solution for safe,
reversible hydrogen storage, with excellent energy efficiency.

McPhy will install a complete system for industrial hydrogen storage at
an Iwatani facility in Japan. The contract was signed just one year after the
two companies first met at the 2010 International Hydrogen and Fuel Cell Expo
in Tokyo. Over the past year, Iwatani experts have evaluated the McPhy
system, visiting installations at the French national CNRS and CEA research
institutions.

"By supplying hydrogen safely, cheaply and reliably, Iwatani is taking a
lead in Japan's quest for a hydrogen-driven society," says Iwatani staff in
the hydrogen business. "The McPhy solid hydrogen storage solution offers a
compelling solution to key challenges of this business."

"McPhy Energy is honored that Japan's hydrogen leader, Iwatani
Corporation, has chosen our solid hydrogen storage system for further
evaluation," says Pascal Mauberger, CEO of McPhy Energy. "This marks our
first foray into the dynamic and all-important Japanese hydrogen market, and
a significant milestone in our strategy of working with industrial leaders in
the most promising markets."

McPhy Energy will exhibit at FC EXPO 2011 - 7th International Hydrogen &
Fuel Cell Expo, in the Device/Material Zone of the Tokyo Big Sight, March 2 -
4, 2011 in Tokyo, Japan.
