The elimination of pollution caused by fossil fuels - When hydrogen is used in a fuel cell to create power, it is a completely clean technology. The only byproduct is water. ... Distributed production - Hydrogen can be produced anywhere that you have electricity and water.
the benefit of using hydrogen combustion over fossil fuel combustion is that it releases fewer emissions-water is the only major byproduct. No carbon dioxide is emitted, and nitrogen oxides, produced by a reaction with the nitrogen in the air, can be significantly lower than with the combustion of fossil fuels.
