Hydrogen production via electrolysis: An overview

Water electrolysis is a relatively new technique for hydrogen generation, having been developed about two centuries ago. This paper examined the incident, situation, and importance, as well as the history, present, and future of different water electrolysis methods. Thermodynamics, energy requirements, and efficiency of electrolysis processes are discussed in this paper. The effects of alkaline water electrolysis, polymer electrolysis membranes, and high temperature electrolysis are discussed and contrasted. Water electrolysis has a limited proportion of the hydrogen generation market because to its high cost, extensive maintenance, poor durability and stability, and low efficiency when compared to other existing technologies. Current water electrolysis technology and expertise are examined and evaluated to see where changes and development are needed for hydrogen generation. The energy requirements, practical cell voltage, process efficiency, temperature and pressure effects on potential kinetics of hydrogen production, and the effect of electrode materials on traditional water electrolysis for Alkaline electrolysis, PEM electrolysis, and heat electrolysis are all examined in this review paper.
