Green Hydrogen in Energy Systems: A Computational Fluid Dynamics Approach provides a comprehensive exploration of how CFD modeling techniques are revolutionizing the development, optimization, and safety analysis of green hydrogen technologies. It addresses the critical role hydrogen plays in the global energy transition while offering practical analytical frameworks.

The book systematically examines the entire hydrogen value chain-from innovative production methods like membraneless electrolyzers to storage mechanisms, transportation systems, and end-use applications. Through detailed CFD simulations, it demonstrates how computational modeling can solve complex fluid dynamics challenges unique to hydrogen systems, improving efficiency and addressing safety concerns essential for widespread adoption.

This book serves as a reference for graduate students, researchers, and energy practitioners focused on hydrogen technology, fluid mechanics, renewable energy systems, and computational modeling.
