Hydrogenics to Supply On-Site Hydrogen Generation and Storage Unit to Support Ford Motor Company's Fuel Cell Center Test Laboratory

Market Wire, December, 2007

Hydrogenics Corporation (TSX: HYG)(NASDAQ: HYGS), a designer and manufacturer of hydrogen and fuel cell systems, today announced that it has been awarded a contract to supply an onsite HySTAT® Hydrogen Station to Ford Motor Company's Fuel Cell Centre, located beside the company's Vehicle Testing Grounds in Dearborn, Michigan.

Built on a modular platform to serve various areas of hydrogen vehicle testing, the HySTAT-30 Hydrogen Station will generate hydrogen by electrolysis, a process involving the splitting of water into high purity hydrogen and oxygen, and then compress the hydrogen to store at 5000 psig. The hydrogen generation (electrolyzer) module will have the capacity to produce 60 kilograms of hydrogen each day and on-site storage as backup.

"Onsite hydrogen stations play a key role in building our future hydrogen infrastructure for a broad range of emerging hydrogen and fuel cell applications," said Daryl Wilson, Hydrogenics President and Chief Executive Officer. "There are several pathways to hydrogen with electrolysis being one of the most reliable, with the capability of integrating with renewables to produce 'on-demand' quantities of hydrogen in a totally clean and sustainable manner."

Hydrogenics has worked together with Ford in the past (as Stuart Energy), including the supply of a hydrogen refueling station at Ford's Proving Grounds in Arizona.
