Alkaline water electrolysis is one of the easiest methods for hydrogen production although it is relatively expensive technology
Alkaline water electrolysis has a long history in the chemical industry. It is a type of electrolyzer that is characterized by having two electrodes operating in a liquid alkaline electrolyte solution of potassium hydroxide (KOH) or sodium hydroxide (NaOH)
Hydrogen is the lightest and most abundant element in the universe and its energy-to-mass ratio far exceeds fossil fuels.
