DigiTain - Digitalization for Sustainability

In the project “DigiTain”, IVW and its partners will develop an innovative winding process for the production of H2 pressure vessels to industrial maturity. There will be a digitalization to optimize the process as well as the quality of the pressure vessels.

The increasingly present climate change underlines the importance of technical developments related to sustainability. In the transport sector, electric drives offer great potential for sustainable mobility, especially when combined with fuel cells and hydrogen tanks. In order to emphasize sustainability aspects, a sustainability-oriented development process (SDP) for fully digital product development is being elaborated in the project “DigiTain – Digitalization for Sustainability”. The project involves 27 other partners from industry and research. To apply and validate the SDP, a vehicle with a hybrid drive concept (fuel cell with HV battery system) is being developed. One key element is the hydrogen pressure vessel. So-called Type-IV tanks (CFRP with internal plastic liner) enable the required high pressures due to the low volume-related energy density of gaseous hydrogen at room temperature and fulfill lightweight construction requirements. They represent a classic field of application for fiber reinforced polymer composites.

Together with our partners, IVW optimizes and enhances a special direct towpreg winding process for the production of Type-IV tanks. Objectives are increasing the efficiency and sustainability of the process and transitioning it from the current laboratory scale to industrial readiness. Process digitalization ensures data acquisition for digital twins to be used for process optimization and quality assurance. Innovative material technologies, that promise improved properties and resource efficiency, will also be investigated. These include „thin-ply“-materials, whose suitability for the production of Type-V tanks is being evaluated.
