Pentadyne Wins Landmark Flywheel Energy Recycling Rail Project for New York City

CHATSWORTH, Calif.--(Business Wire)--
Pentadyne Power Corporation (www.pentadyne.com), a world leader in flywheel
energy storage systems, announced that the Metropolitan Transit Authority of New
York (www.mta.nyc.ny.us) will use Pentadyne as the supplier of a 2.4 megawatt
energy recycling system that will be used to capture, store and reuse braking
energy of trains on a station of the Long Island Railroad.

The MTA oversees all of New York City`s world-renowned subways, commuter trains
and buses. It is North America`s largest transit authority, providing 2.6
billion passenger trips each year - the equivalent of about one in every three
users of mass transit in the United States and two-thirds of the nation's rail
riders.

The pilot project has major financial support from the New York Power Authority
(www.nypa.gov), which selected Pentadyne as the supplier.

The project will involve an array of sustainable, environmentally responsible
carbon-fiber flywheel systems that capture and store braking energy from slowing
trains, then reuse that energy for acceleration.

The concept is similar to that used by hybrid cars, but the hazmat-free flywheel
technology is far more rugged and energy efficient than hazardous chemical
batteries used in hybrid cars.

The NYCMTA and NYPA thoroughly evaluated a variety of flywheels, chemical
ultracapacitor systems and batteries for this new project. They selected
Pentadyne to provide a new and improved high-duty-cycle flywheel system based on
a demonstration system that exceeded expectations in extensive NYCMTA tests
performed several years ago.

Pentadyne`s new and improved version of the original high-duty-cycle flywheel
will capitalize on Pentadyne`s extensive commercial experience in the design and
manufacture of highly reliable, safe and energy efficient flywheel technology.

Pentadyne President & CEO Mark McGough cited this new project as a milestone for
the company: "This will be our first deployment in the rail market, and we
couldn`t be more gratified that the nation`s largest MTA chose Pentadyne for
this landmark project. We are confident that this will lead to many other
projects with the MTA of New York City and with other electric rail facilities
throughout the nation and abroad."
