Hydrostatic Pressure Retainment (HPR) is a gaseous storage concept that may be directly applicable to onboard vehicular hydrogen storage. A cellular polymer (or polymeric foam) may be used as a hydrogen storage media within a conformable automotive fuel tank. Cellular polymers are lightweight, hydrogen permeable, and are near-ideal HPR structures. HPR maximizes the material efficiency by putting the polymer in a tri-axial hydrostatic stress state, thereby reducing tank weight and cost. HPR is essentially a matrix of multiple spherical pressure vessels in an arrangement that may be likened to the atomic structure of crystalline metals (ie: FCC, BCC). Because this may be treated as a series of multiple pressure vessels, an automotive hydrogen fuel tank may take a conformable geometry to the automobile's frame/chassis. HPR Theory may be a practical option for the automotive industry to use for on-board vehicular gaseous hydrogen storage. The main advantages include safety and conformability, allowing for low-pressure, highvolume gaseous storage. A cellular polymer may be the best HPR material media due to its low weight and hydrogen permeability. Currently, researchers at Ohio University are using Finite Element Methods to examine the practicality of an HPR pressure vessel for automotive hydrogen storage.
