Strizki runs the 3,000-square-foot house with electricity generated by a 1,000-square-foot roof full of photovoltaic cells on a nearby building, an electrolyzer that uses the solar power to generate hydrogen from water, and a number of hydrogen tanks that store the gas until it is needed by the fuel cell.I would imagine that the cost of the fuel cell is still high, but "early adopters" of any technology are the people who drive the cost down for the rest of us.
In the summer, the solar panels generate 60 percent more electricity than the super-insulated house needs. The excess is stored in the form of hydrogen which is used in the winter -- when the solar panels can't meet all the domestic demand
