"DEP and Progress Energy jointly funded the project, and Toronto- based Hydrogenics Corp. provided the hydrogen generation system. The fully integrated fuel cell and 5-kilowatt photovoltaic (PV) solar system are supplementing a portion of the electricity used at the park's Wildlife Encounter Pavilion..."
"PV cells -- frequently called solar cells -- convert sunlight into electricity. At Homosassa Springs, these PV cells power an electrolyzer that splits water into its two gaseous components, hydrogen and oxygen. The hydrogen gas is stored for later conversion into electricity by the fuel cell [at night obviously]".
"This project uses existing, proven technologies to provide simple, cost- effective environmental benefits to one of the most pristine areas of natural Florida," said DEP Deputy Secretary for Regulatory Programs and Energy Allan Bedwell. "Visitors to Homosassa Springs will now experience more than the Real Florida -- they will glimpse our nation's energy future."
We know there are engineers and economists reading this and we know you're wondering about the cost benefit of this technology bundle. You'll have to hold that question for a few years. It's not mass produced; and should be seen as analogous to Henry Fords first prototype "Model-A". Proceeding with that anaology, its been roughly a century since Henry's "A" hit the streets and became the car for everyman.
