Hydrogen power system unveiled in Maine

WISCASSET, Maine - A $250,000 demonstration project that produces hydrogen energy to provide backup lighting and warmth at the Chewonki Foundation's environmental education center was hailed at its unveiling Monday as the first of its kind in the nation. The nonprofit foundation teamed up with the Portland-based Hydrogen Energy Center to develop the system that was touted as an example of the kind of cutting-edge technology that can reduce dependence on fossil fuels and help ease global warming.
"Hydrogen represents a huge growth industry, and the creation of this partnership will put Maine on the leading edge as this industry expands," said Gov. John Baldacci, who signed an executive order to promote the development of hydrogen energy in Maine. The system unveiled at Chewonki uses renewable power — from solar panels atop the center and purchases of "green" electricity — to produce hydrogen from water through a process known as electrolysis. New technology that produces the gas at high pressure eliminates the need for a costly compressor. Developers of the system said it's the nation's first publicly accessible direct high-pressure hydrogen energy system as well as the first complete hydrogen energy system in Maine. Because hydrogen is flammable, the electrolyzer and eight cylinders with an overall capacity of 2,080 cubic feet of the gas are stored in a wood and concrete shed in the woods behind the center. The gas is then piped into the center, where three fuel cells can each convert it into one kilowatt of electricity. That power will be available in the event of an outage to supply four days' worth of lighting, operation of the building's water pump and warmth for animals that include a turtle, an iguana and an alligator.
