What does electrolysis consist of?
As we have already mentioned in the previous section, electrolysis consists of the separation of water into its elements —hydrogen and oxygen— through the application of an electric current. As well as the two electrodes (anode and cathode), a component called electrolyte is required. This can be an acid, a base, or a salt dissolved in water, and serves to facilitate electrical conduction. It was Faraday who first formulated the principle of electrolysis in 1820.
In the case of renewable hydrogen, the electricity that is applied in the process is generated from renewable sources. The hydrogen released when the water decomposes is collected and undergoes a process that removes impurities and enables it to meet the required quality standards. It is then stored in tanks or transported through pipelines for distribution.
