The industrialization of hydrogen technologies requires robust validation of components and systems under realistic and extreme operating conditions. Using Bosch H₂ Test Field as a practical reference environment, this presentation discusses broader validation challenges and operational learnings for high-pressure hydrogen applications.

 The test field supports both component and full system validation at pressures up to 875 bar, with mass flows ranging from 0.025 to 130 g/s and temperatures between -60 °C and +85 °C. It allows testing of complete tank systems as well as individual components using flexible test setups and high-precision measurement technology.

 A key focus is the ability to simulate real-world operating conditions, enabling reliable assessment of performance, durability, and safety. In addition, an integrated hydrogen storage and recovery system supports efficient operation, with up to 95% hydrogen recirculation.

 Drawing on one year of operational experience, the presentation will provide insights into typical test setups, challenges in high-pressure hydrogen validation, safety requirements, risk mitigation, and lessons learned from early applications.
