The TOPAQ Hydrogen Supply System from Poppe + Potthoff provides an integrated solution for safe and scalable hydrogen distribution. Covering the complete hydrogen path from the storage tank to the powertrain, the modular platform reduces integration effort through validated components and standardized interfaces. It supports both fuel cell systems and hydrogen combustion engines, enabling flexible system architectures for a wide range of applications.

The system includes On Tank Valves (OTV), Thermal Pressure Relief Devices (TPRD), high pressure tubing, Parallel Charging Units (PCU), adapters, the High Pressure Regulation Unit (HPRU), and the new Tank Control Unit (TCU). The TCU combines hardware and software with integrated diagnostics to increase system availability, detect anomalies at an early stage, and reduce maintenance effort.
