The materials technology discipline interfaces with a large number of hydrogen-driven research challenges, such as developing ultra-low weight polymer composites, exploiting benefits from 2D materials (e.g. graphene and ultra-thin carbon fibre tapes), creating barrier layers and coatings, developing material design methods to avoid liquid hydrogen leakage and tank failure, developing engineering guidelines for the design of linerless liquid hydrogen tanks, developing and exploiting metallic materials for mid-to-high temperature applications for hydrogen rich environments and studying the embrittlement of metallic materials subject to hydrogen.
The cryogenics & heat management discipline targets to develop models and methods to predict performance of cryogenic tanks, including thermal and fluid modelling, fluid sloshing, boil-off, influence of tank design parameters on mission performance, experimentally validated solutions, integration of turbomachinery in the fuel systems, heat management including optimal use of liquid/supercritical hydrogen as a heat sink, heat exchanger design, thermal performance of tank designs, modelling of vacuum and foam filled tanks, fluid aspects of composite tank design, dynamic cryo-tank modelling integrated into vehicles.
Here we collaborate between the disciplines material science, cryo tech and heat management. Partners are Chalmers, RISE, GKN Aerospace, Oxeon, Scania and Volvo.
