Renewable Energy Solutions for Fueling the Future. Green hydrogen, which is produced by using renewably generated electricity that splits water molecules into hydrogen and oxygen, holds significant promise to meet global energy demand while contributing to climate action goals. Currently, the production of green hydrogen is not yet economical or efficient enough. The key to solving this problem is through the development of innovative electrocatalysts. This book reviews recent research and perspectives on these essential areas of focus and provides must-have information for moving new research in green energy forward.
