Safety, Materials, Water, Emerging Technologies and Society

Hydrogen Energy Systems: Volume 4 addresses the engineering disciplines and societal dimensions that cut across every hydrogen application — the knowledge that separates competent hydrogen engineers from genuinely safe and effective ones.

Safety engineering is treated comprehensively: hazard characterization, quantitative risk assessment, consequence modeling, codes and standards including NFPA, ISO and ATEX, facility design, detection systems, and safety management culture. Materials science covers hydrogen embrittlement mechanisms, material selection for high-pressure and cryogenic service, composite pressure vessel design, membrane materials, and catalyst degradation. Water resource management addresses a frequently overlooked topic — the water quality requirements, treatment technologies, and resource constraints that govern large-scale electrolysis deployment.

Emerging technologies surveys the research frontier: next-generation electrolysis, photoelectrochemical splitting, biological production, thermochemical cycles, and advanced storage materials. The final chapters examine the global hydrogen economy and trade routes, transportation applications in depth from passenger vehicles to aviation, and the critical but often neglected topic of social acceptance and public perception — the human dimension that will ultimately determine how fast the hydrogen transition proceeds.

Covers: Chapters 30–36.
