Electrolysis of water is the process of breaking down water (H₂O) into hydrogen (H₂) and oxygen (O₂) using electrical energy.
It is a clean method for producing hydrogen, especially when combined with renewable energy sources (e.g., solar and wind), making it nearly carbon-free.
This method offers the advantages of zero carbon emissions, production of high-purity hydrogen, and applicability to a wide range of locations and scales.
The reactions that take place inside the electrolyzer are as follows:
Cathodic Reactions (Reduction Reactions) : 2H_2 O+2e^-→H_2 +2OH^-
Anodic Reactions (Oxidation Reactions) : 4OH^-→2H_2 O+O_2 +4e^-
Alkaline Electrolysis : This method uses an aqueous solution of potassium hydroxide (KOH) or sodium hydroxide (NaOH) as the electrolyte.
The method is relatively inexpensive and durable, but can be less power-efficient.
Proton Exchange Membrane Electrolysis (PEM) : A solid polymer membrane (PEM) is used as the electrolyte.
This method offers high efficiency and generates high-purity hydrogen, but is relatively expensive.
Solid Oxide Electrolysis (SOE) : This method operates at high temperatures (around 700–1000°C) and uses solid oxide as the electrolyte.
This method is highly efficient but presents durability issues at high temperatures.
