Within the 3 year project “MaTaInH2”, the project partners Mahle, TUM and IVW are pursuing the goal to industrialize high volume hydrogen pressure vessels production at reduced product costs.
Due to increased public funding and the current changes in society, new vehicle registrations of electric cars in Germany are steadily increasing. However, in commercial use, especially in freight transport, battery-electric vehicles have not yet been established. One solution to the storage problem is fuel cell technology in combination with a hydrogen storage tank, in which the hydrogen can be stored under high pressure. The pressurized hydrogen tank is thus a key element of hydrogen and fuel cell technology especially regarding high ranges. The high nominal pressure of 700 bar and the lightweight construction requirements for mobile applications require the use of carbon composite materials. As part of the MaTaInH2 project, a Type-IV hydrogen pressure tank is being developed and optimized, which will be manufactured by using a winding process and whose properties will subsequently be validated. Within the consortium, IVW started the characteriza-tion of the materials and is involved in the industrialization and optimization of the process. In order to better meet future requirements for filament winding, the existing winding process at IVW is being optimized for the economic production of large series. Furthermore, the knowledge gained from the production of pressure tanks will be used to specify an industrial-scale winding system. Finally, an overall analysis will be carried out in relation to the project and development goals.
The project “MaTaInH2 – Material-Efficient and Cycle-Time Optimized Industrialization of H2 Pressure Tanks” is funded by the Federal Ministry of Transport and Digital Infrastructure (BMVI) on the basis of a decision by the German Bundestag as part of the program “National Innovation Program Hydrogen and Fuel Cell Technology Phase 2 (NIP II) (funding reference 03B10111C).
