Hydrogen holds great promise as a fuel in our economy because it is a gas and can be transported through pipelines, it burns without producing pollutants, and it could be used to fuel cells to generate electricity on demand. Hydrogen can be produced by the electrolysis of water to which a drop or two of sulfuric acid has been added to make the solution electrically conductive. The overall chemical reaction is 2H2O(l)→2H2(g)+O2(g) E°=-1.23V How much electrical energy, in kWh, is required to produce 1.00 kg H2(g)? H = 1 g/mol
