Modeling and analysis of laminate structures of a pressurized hydrogen tank

Abstract

Hydrogen storage involves technology development and it is one of the principal fields of improvement to enhance the use of hydrogen energy. The major problems to solve is the adequate materiel chose and the temperature control under high storage pressure. In this work, we are going to present the effects of geometry and inconstant mass flow rate on the pressure ant temperatures within a pressurized hydrogen cylinder during refueling, three laminate composite materials are used and investigate for hydrogen storage tank. The simulations are conducted using a Computational Fluid Dynamics (CFD) tool. The results show that, adding the carbon fiber laminate increases the hydrogen storage pressure. Also, the model shows that the temperature is maintained at a common level but with different distributions.
