MISSISSAUGA, Ontario, June 30, 2010 (GLOBE NEWSWIRE) -- Hydrogenics Corporation (Nasdaq:HYGS) (TSX:HYG) ("Hydrogenics" or the "Company"), a leading developer and manufacturer of hydrogen generation and fuel cell products, today announced that it has been selected by Ontario's Independent Electricity System Operator (IESO) to participate in the Alternative Technologies for Regulation Demonstration Project for utility-scale grid stabilization. Over a two month period, the load from a Hydrogenics HySTAT TM electrolyzer will provide regulation services within Ontario's electricity market by responding to power signals from the IESO. 

Using an electrolyzer currently installed at Hydrogenics' corporate headquarters, the IESO and Hydrogenics will work together to assess how well the hydrogen equipment follows regulation signals in a real-world scenario. In doing so, Hydrogenics will aim to provide better balancing of electrical supply and demand while alleviating local transmission constraints.

"We are very pleased to have been selected for this ambitious study by Ontario's IESO," said Daryl Wilson, President and CEO. "We believe this demonstration will showcase the smart-grid capability of utility-scale hydrogen technology, which can and will be used for both grid stabilization and energy storage in the years to come."
