To produce 1 kg of hydrogen, nine times the amount of water is necessary, i.e. nine litres

And producing hydrogen by electrolysis is more valuable than curtailing power production or dissipating it in a resistor bank when there is truly excess supply. However the larger issue for renewable energy is undersupply, not oversupply. When the sun isn't shining and the wind isn't blowing, there's still demand to be met. There needs to be a way to meet it. If it's not dispatched. Hydrogen gas is generated by the electrolysis of liquid ammonia which has high hydrogen capacity of 17.8 mass%.

Hydrogen production by water electrolysis can be economically viable by using electrical energy from re- newable sources such as photovoltaic solar energy [1-4]. Our previous studies have relied on the use of salt water as electrolyte [5-8]. In this article, we will vary the nature of the electrolyte leaning towards wastewater deemed by their richness in bacteria which are the basis for. Most large-scale hydrogen production by electrolysis is using alkaline electrolysers (AE). PEM units use pure water and are relatively small but can be flexible in operation. They can also generate hydrogen at high pressure (30-60 bar, compared with alkaline 1-30 bar). However they use expensive electrode catalysts (platinum, iridium) and membrane materials and have short lifetimes. Solid. Hydrogen produced using electrolysis is currently around four times more expensive, even before the cost of the electricity required is factored in. Only 1% of the hydrogen produced in France is obtained using electrolysis technology.
