The modular hydrogen supply system TOPAQ enables safe and efficient hydrogen flow from high-pressure storage tanks to fuel cells or hydrogen combustion engines. It combines essential components such as on-tank valves, thermal pressure relief devices, lines, manifolds (parallel charging unit), and pressure regulation units. The system can be configured to match specific application needs, making it suitable for both mobile and stationary use. Typical use cases include road and off-road vehicles, stationary hydrogen storage, and infrastructure solutions such as multi-element gas containers. With its flexible architecture and safety-focused design, TOPAQ supports the development of reliable hydrogen systems across multiple industries.
