Sept. 30, 2002 — Proton Energy Systems has launched its latest HOGEN® hydrogen generator series, with a new model capable of producing hydrogen continuously from renewable energy, grid power, or any mix of the two.

Proton’s HOGEN® RE (Renewable Energy) hydrogen generator made its debut at Hydrogen Expo, the world’s largest trade show for hydrogen devices and fuel cells.

The HOGEN® RE hydrogen generator is designed to make maximum use of intermittent renewable energy while still ensuring reliable hydrogen supply. It may be powered through either 100 percent renewable energy sources, such as solar, wind or wave-generated electricity, or any percentage combination of renewable and grid power.

The unit continuously and automatically adjusts for changing renewable power availability.

“The primary benefit of the HOGEN® RE generator is that it can accommodate a constantly changing mix of available energy sources,” said John Speranza, renewable program engineering manager, Proton Energy Systems. “The HOGEN® RE generator will take as much energy as it needs from the grid to augment renewable energy inputs, ensuring operation 100% of the time.”

Speranza added, “The new renewable energy-capable generator is a flexible, dependable tool for hydrogen generation. It’s an environmentally superior product that adapts to produce hydrogen for the customer by the most efficient method available.”

Proton Energy Systems President and CEO Walter (“Chip”) Schroeder said, “The cornerstone of Proton’s business plan has been to apply our core competence in hydrogen generation to advancing sustainable energy. Our HOGEN® RE systems transform renewable sunlight and wind to hydrogen which can be used for industrial purposes or as a zero-emission fuel. We are excited about the potential of this technology to enhance the usefulness of renewable energy sources.”

The HOGEN® RE system will interface directly with photovoltaic (PV), wind or other renewable sources. Other enhanced features for the HOGEN® RE include a modular design and remote diagnostic and control capabilities.

The HOGEN® RE system incorporates features resulting from Proton’s research, development and testing efforts during the last four years. Proton’s first HOGEN® hydrogen generator developed for a renewable energy project was a HOGEN® 300 generator, installed in 1999 for a Stirling engine energy demonstration project at the APS Division of Pinnacle West Corporation. Since its installation, the generator has run for more than 4,000 hours. It currently provides hydrogen fuel for APS’ low emissions fleet vehicles in Phoenix.

In June, a photovoltaic-capable HOGEN® generator was installed to provide hydrogen for a fuel cell in the GlasshusEtt, Sweden’s renewable-energy demonstration model home in Stockholm.

Since they were first introduced in 2001, HOGEN® units have been sold to hydrogen gas users around the world. HOGEN® generators are currently used to supply hydrogen gas in generator cooling, materials processing, semiconductor manufacturing, fuel cell research and meteorology applications. HOGEN® units offer a safe and cost efficient alternative to hydrogen supply through cylinders or bulk gas supply. Instead of labor, fuel, delivery and storage costs associated with stored hydrogen, HOGEN® generators make hydrogen available as needed.
