The urgent need to combat climate change and the rise in greenhouse gas emissions necessitate a greater focus on renewable energy sources. The European Union's Flightpath 2050 initiative aims for a significant reduction in CO2 emissions per passenger kilometer, targeting a 75% reduction, along with a 90% reduction in NOx emissions. Hydrogen has emerged as a promising alternative propulsion technology for aviation, offering a clean and efficient energy source. However, a major challenge is ensuring the safe and efficient storage of this high-energy gas.

High-pressure tanks are a promising option for storing gaseous hydrogen, providing high energy density at moderate temperatures and pressures. However, effective utilization of these tanks requires a thorough understanding of the permeation properties of the materials used and the tank configurations. Hydrogen permeation through tank walls can impact energy storage efficiency and pose safety risks.

To develop innovative hydrogen tank structures for aviation, it is crucial to investigate the permeation properties of potential materials. A permeation testing setup has been designed, incorporating a quadrupole mass spectrometer for hydrogen. The measurement principle and the operation of individual components for temperature and pressure control are detailed. A temperature-controllable holder accommodates circular disc samples of various materials and geometries for determining permeation coefficients. A series of measurements with resin are conducted to validate the functionality of the setup and estimate manufacturing accuracies, thereby determining the influence of sample thickness. Subsequent experiments involve varying curing cycles and subjecting samples to different temperature levels during measurement to analyze the temperature dependence of permeation coefficients.
