  The idea of this technology, is that more hydrogen than you need would be produced during the “sun hours”, so it could be storaged and use during “dark hours”.
  There is a device called fuel cell, it basically puts the previously produced hydrogen and air together and produces energy. So we wouldn’t have to worry when is dark. Isn’t it great?
