Summary
Hydrogen energy is rapidly becoming a practical pathway to decarbonize power systems and hard-to-electrify sectors, while also providing long-duration flexibility to renewable-dominant grids. However, large-scale deployment still faces key engineering barriers, including cost-effective and safe hydrogen storage, efficient and grid-aware power-to-hydrogen operation, and robust planning and control under uncertainty. At the same time, the growing availability of operational data and advanced computational methods creates a timely opportunity to accelerate hydrogen system design, operation, and reliability through modern AI tools.
This Special Issue on Hydrogen Energy aims to collect high-quality, engineering-oriented contributions that advance the modeling, design, optimization, control, and real-world deployment of hydrogen technologies. The scope covers hydrogen production (especially power-to-hydrogen), storage and delivery infrastructure, hydrogen energy supply chain management, integration with electricity markets and network constraints, and AI-enabled methods that improve performance, safety, and scalability. Both original research papers and review articles are welcome, with an emphasis on works that provide clear technical insights, practical relevance, and reproducible methodologies.
Suggested themes include (but are not limited to):
· Hydrogen storage: compressed, liquid, cryogenic, solid-state, LOHC, and underground storage
· Power-to-hydrogen and sector coupling: electrolyzer modeling, degradation-aware operation, hub planning
· Hydrogen energy supply chain management: production to storage coordination, logistics optimization, and infrastructure planning
· Grid integration: co-optimization with renewables, market participation, congestion and ancillary services
· AI tools for hydrogen systems: forecasting, anomaly detection, digital twins, surrogate modeling, RL/MPC
· Safety, monitoring, standards-relevant testing, and reliability engineering
· Techno-economic analysis (TEA), life-cycle assessment (LCA), and uncertainty-aware planning
