HYG iShares iBoxx Dollar High Yield Corporate Bond

Hydrogenics Corporation (Nasdaq:HYGS) (TSX:HYG) ("Hydrogenics" or "the Company"), a leading developer and manufacturer of hydrogen generation and hydrogen-based power modules, today announced that it has been selected as a Preferred Respondent by the Independent Electricity System Operator (IESO) for Ontario in its procurement for Grid Energy Storage. This Power-to-Gas project will deliver 2MW of storage capacity and be located in the Greater Toronto Area. Hydrogenics will supply the facility's next-generation PEM electrolyzers and is partnering with Enbridge Inc. to develop, build and operate the energy storage facility to provide regulation services to the IESO under contract.

"Storage facilities on the grid are a real game changer," said Bruce Campbell, President and CEO of the IESO in a press release. "Our electricity system was built on the concept that you can't store large amounts of electricity – we produce electricity at the same time that we consume it. Energy storage projects will provide more flexibility and offer more options to manage the system efficiently."

Daryl Wilson, CEO of Hydrogenics, added, "We are very excited to have been awarded this Power-to-Gas project, the first of its kind in North America. We have already experienced the positive impact of having a highly visible reference site with E.ON in Germany, and our partnership with Enbridge will make this application an excellent reference site closer to home. We appreciate the leadership of the Ontario Ministry of Energy to invest in clean energy storage technologies and the IESO for providing this platform for energy innovation."

Today, we continue to prove that our hydrogen-based energy storage technology will transform the energy sector by providing services to grid operators to convert renewable generation when it is not needed into renewable power, fuel or heat when and where it is needed.
