High Pressure Hydrogen Storage Tank: A Parametric Design Study

Low hydrogen density of high pressure vessels is the primary concern in compressed hydrogen storage techniques. To increase densities, a new tank design is proposed in this paper with simulative design approaches. A novel design feature of this tank is a multilayered wall, which is composed of a "dynamic wall" capable of absorbing hydrogen while supporting the tank and preventing hydrogen permeation and embrittlement. Such a proposed tank is modeled with finite element method to determine required properties towards achieving the Department of Energy (DOE) targets of 2010 and 2015. Parameters and relations for this engineering design are obtained.
