LIGHTWEIGHTING
The TOPAQ hydrogen supply system enables the safe and efficient routing of hydrogen from the tank to the fuel cell or hydrogen combustion engine
material expertise to develop ‘PPH2’, a material tailored for hydrogen component production. Traditional components are often made from austenitic stainless steel, which requires thicker walls for high- pressure resistance due to its lower strength, leading to increased weight, costs, and CO2
emissions. PPH2, an
alloyed quenched and tempered carbon steel enhanced by an inhouse PPSH annealing process, offers high
mechanical properties allowing for thinner-walled, lighter, and cost- effective components with reduced CO2
emissions when compared to
components made from stainless steel. PPH2 was tested in accordance with DIN EN ISO 11114, ANSI/CSA CHMC 1-2014 and approved for use in hydrogen applications under EU Regulation (EC) No. 79/2009. In a cooperation with the testing institute TÜV SÜD Chemie Service GmbH,
The PPH2 material allows for a reduction of weight, material costs and CO2
compared to stainless steel Test stands for hydrogen component validation
The Poppe + Potthoff group also offers the in-house development and construction of test stands for various applications. These test rigs can be used in research & development to constantly benchmark manufacturing processes and H2 component quality. Hence, components must undergo endurance tests under extreme pressure pulsations and temperature changes. The test stands allow for flexible solutions while simulating diverse conditions and environmental changes. Alongside pressure cycle test rigs, as well as burst and leak test solutions, P+P also offers a 1050 bar gas leak test system for hydrogen component development. The rig enables the use of nitrogen, helium, as well as a moulder gas hydrogen blend of 95/5. Poppe + Potthoff itself uses these test stands during the development of its hydrogen components and systems. The analysis of data gained during product testing allows for a continuous optimisation of hydrogen systems and a shortening of development cycles.
Poppe + Potthoff has also been able to have PPH2 tested according to a newly developed testing methodology. The results of this test confirm the successful outcome of previous tests. Poppe + Potthoff independently develops and produces system components such as pipework or rails made of PPH2 for up to 700 bar nominal pressure. Pipework, H2 rails (manifolds), and interfaces made from PPH2 have been certified by an independent testing institute according to EC79 and successfully tested according to the maximum requirements of HGV3.16. ●
