Are you sure the hydrogen storage is still active? That page does say "This project has been operating autonomously since 2009" but the projects page on the same site lists the hydrogen village as lasting from 2008-2010 https://frontierpowersystems.ca/projects/. Frontier Power Systems is also a "wind-diesel" provider - so they certainly aren't separated from oil companies (though this doesn't automatically mean their intentions aren't genuinely to reduce fossil fuel usage as GP was saying, they even seem to be doing battery storage systems now).
Checking further into the projects list, the first project in Ramea for "wind-hydrogen-diesel" (first time I've seen that one) demonstration is listed as lasting longer but this article notes it hardly ever ran because "issues were experienced with the storage aspect of the project" i.e. the hydrogen storage https://www.cbc.ca/news/canada/newfoundland-labrador/ramea-w... I didn't exhaustively check the project list but, of the ones I did, I didn't see an active wind-hydrogen systems. Only active wind-battery or wind-diesel systems. WEICan also has active wind+battery systems running on Prince Edward Island https://www.weican.ca/ (click view details for the specifics) but no hydrogen.
Maybe all of that is in same way inaccurate and there are actually great details of the hydrogen storage success. Unfortunately I can't find any such details saying "that's the case and here is the data about how successful it has been for the last decade", just the above info saying it was tried for a short period, didn't work out, and other system types are currently in place.
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.”
