It’s a rather old project (2009), so many articles covering it are defunct. Found some of the info:
“The purpose of the Prince Edward Island (PEI) Wind-Hydrogen Village is to use excess wind energy along with hydrogen technologies to offer sustainable energy. Excess electricity produced by wind turbines on the island is being used to power a 300kW uni-polar electrolyzer.
A uni-polar electrolyzer uses alkaline liquids, rather than solid polymer, as its electrolyte. The electrolyzer can produce about 6kg of hydrogen per hour. The hydrogen is then stored as compressed gas in storage tanks that have a total capacity of about 500kg. The hydrogen is then used in the bi-fuel hydrogen/diesel genset to power the village when there is no wind.”
How many MW of wind turbines? How big electrolyzer? How big energy storage? Investment cost? Running costs? Reliability?
