$Fuelcell Energy this stock energy will rise anyway. Hydrogen energy better than li battery. 1kg of hydrogen contains 250 times more energy than 1kg li battery. This means that, one ton of lithium battery contains the same energy as four kg of hydrogen. Solar and wind energy must be stored before using it at home. The energy can be stored in a battery or hydrogen. That is, you can create a battery that in the end will be destroyed .Thi is pollution. Or you can create pure hydrogen energy from water. And return the water to the ground after using hydrogen energy. Understand ?
