We all know that electrolysis of water is a process by which water – H2O is decomposed into oxygen O2 and hydrogen gas or H2. This is done because of an electric current which gets passed through the water. When we talk about electrolyzer we are referring to a device that splits water into oxygen and hydrogen with efficient and planned use of electrical energy.
When we take trouble to give electrical inputs from renewable source, we can be sure that hydrogen does not leave behind any carbon footprint making it eco-friendly and environmentally safe. This is often considered to be one of the most practical ways to generate zero carbon fuel supply.
