About this Research Topic
There has been a rapid growth in renewable energy-related industries that are eco-friendly and can resolve the problems of fossil fuel shortages and environmental pollution globally. Electricity production through renewable energy allows for an eco-friendly and sustainable method of power generation. However, renewable energy power generation is irregular, and there is a need for hybrid systems that combine production and energy storage systems. Hydrogen is a promising energy carrier for renewable and sustainable energy systems owing to its high energy density and zero carbon emission. Water electrolysis is a next-generation energy source that can produce high-purity hydrogen, a clean energy source. It is a technology that produces, stores, and then uses electricity produced from renewable energy, and it has characteristics that are suitable for high-capacity electrical power storage.
Much effort has been directed at the development of greenhouse gas emission-free techniques of high-purity hydrogen production such as water electrolysis, which is typically performed using proton exchange membrane water electrolysis (PEMWE) and alkaline water electrolysis (AWE) systems. Although advances have been made in both systems, it still suffers from low materials activity and stability for both the catalyst and membrane, as well as electrolyte leakage, low energy density, and management difficulty on a system scale. Therefore, it is still necessary to generate information about the catalyst, membrane, operating condition in systems, etc in order to truly understand the mechanisms and to develop the new technology.
This Research Topic welcomes the submission of high-quality manuscripts concerning hydrogen production through electrolysis and their applications. This Research Topic will focus on the development of computational material design, synthesis of electrocatalyst and their electrocatalytic activity/stability, and mechanisms. The main themes of interest are:
• Alkaline Water Electrolysis system
• Polymer electrolyte (PEM) Water Electrolysis system
• Electrocatalyst for oxygen/hydrogen evolution reaction
• Reaction mechanisms on precious and non-precious catalyst
• Computational modeling (e.g., Density functional theory, Molecular Dynamic study, Artificial Intelligence)
Dr. Min Ho Seo holds a few patents related to electrolysis technologies. The other Topic Editors declare no competing interests related to the Research Topic theme.
