The three-and-a-half-year BRYSON (BauRaumeffiziente HYdrogenSpeicher Optimierter Nutzbarkeit) project is funded by the German Federal Ministry of Economy and Energy and aims to develop a "space-saving hydrogen storage system with optimized availability". The main participating members of the BRYSON project include BMW AG, Dresden University of Technology Light Engineering and Polymer Technology Institute (ILK), composite engineering and development company Leichtbauzentrum Sachsen (LZS), composite material distributors WELA Handelsgesellschaft and Munich German companies such as the University of Applied Sciences. The goal of the BRYSON project is to develop a new high-pressure hydrogen storage system. The new design should be easy to integrate into the general vehicle architecture, so the project focuses on creating a flat design hydrogen storage system.
ILK, LZS and composite design manufacturer Herone GmbH worked closely to develop a hydrogen storage system consisting of a chain-shaped tubular storage tank. The storage tank is made of braided reinforced thermoplastic composite material. Taking advantage of the rapid production of fabric and thermoplastic composite material, the production cost of the hydrogen storage tank of the fuel cell vehicle can be effectively reduced, and the recovery of the storage tank structure is easier. The design of the new hydrogen storage system not only improves the competitiveness of the products, but also better achieves sustainability.
Alexander Rohkamm, co-founder of Herone GmbH and head of the BRYSON project, said: "The goal of the BRYSON program is to develop a modular storage system that can adapt to the design space of a given vehicle." The processing performance of thermoplastic composite materials makes part design more integrated. While reducing manufacturing costs, improve energy efficiency. Compared with traditional metal and thermoset composite solutions, the ratio between performance and cost is improved. "
Rohkamm pointed out: "Alternative transportation concepts also need to be rethought at every step of the development and manufacturing chain. In the current internal combustion engine vehicle architecture, gasoline and diesel engines share the same installation space, and using the same architecture can save a lot of costs. Similarly, in order to achieve maximum flexibility and economy in the future electric vehicle architecture, the hydrogen storage system can be designed in the space where the high-voltage battery should be placed. Two types of energy sources (hydrogen and battery) are integrated in the same installation In the space, reduce costs and achieve more flexible production."
