FOR IMMEDIATE RELEASE


HYDROGENICS CORPORATION SUCCEEDS IN BID FOR
STUART ENERGY SYSTEMS CORPORATION

Offer extended to January 20, 2005

MISSISSAUGA, ONTARIO, January 6, 2005 — Hydrogenics Corporation (NASDAQ: HYGS; TSX: HYG) announced today that it has been successful in its offer (the "Offer") to acquire Stuart Energy Systems Corporation (TSX:HHO). 31,382,226 Stuart Energy shares, representing approximately 86% of the issued and outstanding Stuart Energy shares (80% on a fully diluted basis), have been deposited to the Offer. The Offer was made at an exchange ratio of 0.74 Hydrogenics shares for every Stuart Energy share.

Hydrogenics has now declared the Offer for Stuart Energy to be wholly unconditional, and has instructed the Depositary, CIBC Mellon Trust Company, to take up and pay for all the shares deposited to the Offer. Payment to the shareholders who deposited their Stuart Energy shares to the Offer will be made by the Depositary as soon as reasonably practicable.

In order to acquire 90% of the outstanding Stuart Energy shares (as required to effect a compulsory acquisition of the shares not deposited to the Offer), Hydrogenics has extended the Offer to enable those shareholders that have not yet tendered to deposit their Stuart Energy shares to the Offer. The offer, as extended, will now expire at 6:00 p.m. (Toronto time) on January 20, 2005. If less than 90% of the Stuart Energy shares are deposited, Hydrogenics intends to effect a subsequent acquisition transaction to acquire the remaining Stuart Energy shares, as described in the take-over bid circular. Upon completion of the compulsory acquisition or subsequent acquisition transaction, Hydrogenics intends to de-list the Stuart Energy shares from the Toronto Stock Exchange. Shareholders are encouraged to tender their remaining Stuart Energy shares to the Offer as soon as possible to receive prompt payment.

Hydrogenics first announced its intention to make the Offer on November 10, 2004 and it mailed its take-over bid circular to the shareholders of Stuart Energy on or about December 1, 2004.

"This is a historic day for Hydrogenics and Stuart Energy, as we join two of the hydrogen industry's established and highly regarded companies to create a new business platform with the scale and financial strength to compete and grow successfully into the future," commented Pierre Rivard, President and CEO of Hydrogenics. "This acquisition gives us a breadth of capabilities and resources that we previously did not possess," said Rivard. "In addition to expanded market penetration and product diversification, the combination will expand our revenue base and cash reserves considerably, and we expect it will be accretive to earnings, EBITDA and cash flow on a per share basis. The acquisition is consistent with our strategy of nurturing a portfolio of value streams so as to reduce our exposure to a singular product, singular market and singular adoption rate."

The integrated company will be well financed and positioned to pursue its aggressive business plan for global growth. Following the closing of the transaction, Hydrogenics expects to have approximately US$120 million in cash and short-term investments, a lean structure that can grow with increased adoption of hydrogen and fuel cells, an unmatched product portfolio, expanded global reach and an accelerated pathway to profitability. The integrated company also expects to achieve significant synergies in facilities rationalization, production cost, supply chain management, and utilization of existing systems and processes that will drive margin improvement.
