Electrolysis involves splitting water molecules into hydrogen and oxygen using a DC electrical current. One of the critical components in the electrolysis process is the DC power supply, which provides the necessary electric current for the electrolyzers using rectifier for hydrogen.
Water electrolysis is one such electrochemical water splitting technique for green hydrogen production with the help of electricity, which is emission-free technology. The basic reaction of water electrolysis is as follows in Eq. (1).
However, there are grid-side limitations for the connection of large water electrolysis plants and their converters, which form the connection. This paper shows nowadays component limitations in power supplies and the challenges in connecting large water electrolyzers.
Several water electrolysis technologies have been assembled in this review. Hydrogen-powered ships, trucks, and even train transportation systems may be commonplace in the foreseeable future because of improvements in hydrogen technology. 1. ).
To make a significant contribution, large-scale water electrolysis and power-to-X plants need to be erected and supplied with sufficient electric power.
