One of the major complaints about wind power is that it isn’t an “on demand” power source, you get electricity when the wind speed is within a certain range, which isn’t always the time when the power is needed. A pilot scheme on Canada’s Prince Edward Island may have the answer. It uses power from windmills to convert water to hydrogen, which can be stored and used as combustible fuel or in fuel cells. Though there are questions about the efficiency of conversion it does offer one possible solution. Possibly future wind farms could incorporate a small hydrogen power plant. When output is greater than demand hydrogen can be produced that would run the plant when output from the windmills dropped below a certain level.
