HyStor - Hydrogen Storage

HyStor - Hydrogen Storage

As part of the HyStor project, critical design features of a cryogenic hydrogen tank made of fibre composite are to be defined, examined in terms of production technology and evaluated. Existing systems will be used for the production-related investigation. The focus is on fibre lay-up technology with an integrated rotary axis. Here, HyStor is making a significant contribution to the application-specific development of the existing system technology. In addition, the capability of the fibre winding process is to be examined and investigated with regard to its suitability for a cryogenic hydrogen tank for aviation applications. To this end, initial production trials will be carried out, primarily at coupon level.  

In addition, a sensor system for structural monitoring is to be developed as part of the project. Various structural health monitoring technologies (hereinafter SHM) based on guided ultrasonic waves (Lamb waves), acoustic surface waves and fibre-optic or dielectric sensors are to be investigated for their applicability under cryogenic boundary conditions. The main challenges of an SHM system for cryogenic hydrogen tanks are the extreme temperature fluctuations and the level changes during operation. In addition to the evaluation and adaptation of the SHM concepts to the cryogenic boundary conditions, the aspects of managing the data obtained and the simple and possibly automated integration of the sensors during the manufacturing process are also considered.trachtet.

„Hydrogen Storage XL“ the DLR Enersphere Approach
The HyStor project enabled the Process Technologies department of the Institute of Lightweight Systems Engineering to take the first steps towards a composite hydrogen tank. Starting with the design, initial concept ideas and production trials, a complete demonstrator was created. This has a length of 2.5 metres and a diameter of 3 metres. It was successfully deposited and cured using the research infrastructure of the ZLP Stade. This video gives an impression of the production process.

The use of hydrogen as a renewable and therefore sustainable energy source for future CO2-free drives holds great potential for decarbonisation. In addition to being used for heavy commercial vehicles or shipping, hydrogen is also used in aviation as an alternative energy source to paraffin or SAF (sustainable aviation fuels) to reduce CO2 emissions.
