The transition toward hydrogen-based energy systems requires safe and efficient technologies for hydrogen storage and supply that can be integrated with renewable hydrogen production. Solid-state hydrogen storage technologies offer significant advantages in terms of volumetric storage density and operational safety, making them attractive for distributed hydrogen infrastructure.
In this study, a 10 kW-scale integrated hydrogen storage and supply system was developed through a collaborative research program between Korea and Switzerland. The objective of this work is to demonstrate the feasibility of integrating hydrogen production and solid-state storage technologies into a unified system capable of stable hydrogen storage and controlled supply.
The developed system consists of three major subsystems: a hydrogen production unit, a solid-state hydrogen storage module, and a hydrogen supply and control system. The system architecture was designed to enable efficient coupling between hydrogen generation and storage processes while ensuring stable system operation under varying hydrogen production conditions.
Special consideration was given to system integration, including hydrogen flow management, thermal control of the storage module, and operational stability during charging and discharging processes. A dedicated control strategy was implemented to coordinate the operation of the production, storage, and supply units within the integrated system.
The integrated platform was constructed at the 10 kW scale, providing a representative demonstration system for decentralized hydrogen energy applications. System-level performance evaluation was conducted to verify hydrogen storage capability, operational stability, and response characteristics during charging and supply operations.
The results demonstrate the feasibility of an integrated hydrogen production?storage?supply platform and highlight the potential of solid-state hydrogen storage technologies for future hydro
