HydroGen, LLC Secures $2 Million in Bridge Financing From Samsung C&T Corporation and Federated Kaufmann Fund

Successfully Re-Starts Commercial Demonstration Fuel Cell Power Plant With Second Generation Electrodes

CLEVELAND, Aug. 28, 2008 (GLOBE NEWSWIRE) -- HydroGen Corporation (the "Company"), a designer and manufacturer of multi-megawatt air-cooled phosphoric acid fuel cell (PAFC) systems, today announced that the Company and HydroGen, LLC, the Company's wholly-owned subsidiary, entered into a Loan and Security Agreement on August 22, 2008 with Samsung C&T Corporation and Federated Kaufmann Fund pursuant to which Samsung and Federated Kaufmann have each agreed to loan $1 million to HydroGen, LLC in two equal installments. A first tranche of $1 million of the loan was released to HydroGen, LLC at the closing on August 22. A second tranche of $1 million will be released to HydroGen, LLC on or before September 30, 2008 based on the achievement of certain milestones.

The proceeds will be used for working capital purposes, including continuing operation of the Company's commercial demonstration power plant at ASHTA Chemicals, Inc. Specifically, the proceeds will sustain operations through the next three to four months during which the Company will seek long-term financing in the form of an equity investment or an acquisition of the Company.

The $2 million bridge loan is secured by substantially all of the assets of HydroGen, LLC and the Company, bears interest at the rate of 12% per annum, and becomes due and payable on December 15, 2008 (which may be extended to no later than February 1, 2009 if the Company is in the process of obtaining shareholder approval for a transaction that will result in the payoff of the loan). Additionally, Samsung and Federated Kaufmann have each received a warrant to purchase up to 400,000 shares of common stock of the Company, exercisable in two equal amounts with each tranche of the loan.

HydroGen CEO John Freeh commented: "We are encouraged that Samsung, our strategic partner, and Federated Kaufmann, a valued shareholder, have teamed to provide the Company with this critical bridge financing. This financing will enable us to continue with our commercial demonstration activities at ASHTA Chemicals, retain key staff who will be required to ensure continuity of our operations, and attempt to complete a sale or other form of financing of the Company.

"Although we have significantly reduced our workforce and burn rate, we have continued to make operational progress. Our ASHTA demonstration plant is now operating with fuel cell stacks that incorporate our second generation electrodes. These electrodes are manufactured with materials that are expected to provide longer life than that of our first generation electrodes. We made this upgrade during an unplanned shutdown after the demonstration plant was operated outside of certain pressure and temperature operating conditions required for proper electrolyte management. Even with our reduced staffing we were able to overhaul the fuel cell module, upgrade the fuel cell stacks with the new electrodes, deliver the overhauled module to ASHTA, improve plant operating procedures, make additional improvements in the balance of plant, and re-start the plant."
