CommScope

MISSISSAUGA, Ontario, Dec. 5, 2012 (GLOBE NEWSWIRE) -- Hydrogenics Corporation
(Nasdaq:HYGS) (TSX:HYG), a leading developer and manufacturer of hydrogen
generation and hydrogen-based power modules, announced that it received an
order for the delivery of HyPM™ XR Series fuel cell power modules from its
US-based partner, CommScope, Inc.

Hydrogenics power modules will be integrated into CommScope's fuel cell
cabinets as the backup power solution for hundreds of wireless sites in North
America, servicing a leading wireless operator. This is the largest single
order from CommScope since the announcement of the strategic alliance between
CommScope and Hydrogenics in 2010. This award is significant as it brings
total orders in the Hydrogenics power systems business to over $100 million
for 2012.

"We are very pleased with this order from CommScope for one of their key
customers in North America," said Daryl Wilson, Hydrogenics' President and
Chief Executive Officer. "CommScope is a leader in providing communications
infrastructure solutions to world's largest telecom players, and hydrogen
backup power cabinets provide a clean, reliable, long-term energy source to
cell sites while avoiding the inherent issues and costs associated with
batteries and diesel generators. We have worked closely with CommScope to
develop and launch a best-in-class outdoor backup power solution for telecom
customers. This year we have seen increased interest for the
CommScope/Hydrogenics back-up power package from telecom players around the
globe, and we anticipate similar interest in 2013."
