Hydrogenics Enters into Strategic Collaboration with StratosFuel for 2.5 MW Power-to-Gas Project in California

North America’s Largest Renewable Hydrogen Plant to Power Fuel Cell Vehicles

MISSISSAUGA, Ontario, Nov. 01, 2016 - 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 entered into a strategic partnership with StratosFuel, which, subject to permitting and funding, would result in North America’s largest zero-emission hydrogen power plant. The 2.5-megawatt Zero Impact Production (ZIP) hydrogen facility in Palm Springs, California will use Hydrogenics’ state-of-the-art PEM electrolyzers to convert wind and solar energy into 1,000 kilograms of renewable hydrogen per day.

The Palm Springs region in California has an abundance of wind and solar power. By using StratosFuel’s power purchase agreement, Hydrogenics electrolyzers will enable StratosFuel to provide clean renewable hydrogen to hundreds of fuel cell vehicles every day in the Southern California region.

“We are very pleased to enter into this strategic collaboration and be the exclusive supplier for the largest commercial MW-scale Power-to-Gas plant in North America,” said Daryl Wilson President & CEO of Hydrogenics. “Our PEM technology gives us the ability to bring the world’s most efficient electrolyzer to the US market for 100% clean, renewable hydrogen production. By working with StratosFuel, we will help them move forward to meet and exceed government regulations on renewable hydrogen and put it to use powering fuel cell vehicles in the area.”

The ZIP Hydrogen facility will be constructed in three phases. Phase 1 - the 2.5 megawatts - is currently undergoing permitting and funding approval and is expected to begin construction in 2017. Upon successful implementation, it is envisioned that the capacity of the plant will be doubled in Phase 2 and further expanded in Phase 3 as the demand for renewable hydrogen grows in the State of California.

“Utilizing wind and solar energy to create hydrogen represents a paradigm shift to a cleaner and more sustainable source of fuel for transportation and industry,” stated Jonathan Palacios-Avila CEO at StratosFuel. “To locally produce hydrogen that is 100% carbon-free is a major milestone, and we are pleased to be working with Hydrogenics to make this a reality.”
