NeMo.bil project integrates Type 4 tanks into mobility system storage rack

As part of next steps for the Federal Ministry for Economic Affairs and Energy-funded NeMo.bil project, the integration of five Type 4 thermoplastic composite (TPC) hydrogen tanks supplied by project partner Avanco Composites (Herford, Germany) into a complete mobility system — including the design and implementation of a dedicated rack structure, developed in close collaboration with project partner Poppe + Potthoff GmbH (Werther, Germany) — has been achieved.

In addition, all other valves and components — including the electronic high-pressure regulation unit (HPRU) and the parallel charging unit (PCU) — were installed directly into the rack’s tank control unit, the central control system that serves as the “brain” of the smart hydrogen supply system. All components are interconnected via P+P high-pressure hydrogen lines, whose interfaces meet the highest leakage requirements.

Notably, the rack serves as the central interface for the entire system and ensures:

• Secure fixation of the hydrogen tanks using clamping systems.
• Defined mounting points for all relevant system components.
• Integration of piping and pressure regulation systems.
• Reliable connection between individual tanks within the system.

To validate the system, comprehensive leak and tightness tests were performed by filling the system with a gaseous medium to detect potential leakages— the next step toward the project’s goal of a fully integrated and safe hydrogen storage solution.
