Abstract
The effect of thermal exposures on several thermodynamic processes involving the storage and use of hydrogen has been examined using the NIST REFPROP database. The thermal environment could be the result of a fire or other thermal events. The thermodynamic processes considered are isochoric (constant density) heating, isenthalpic expansion, and isentropic expansion. In addition, isochoric heating followed by either an isenthalpic or isentropic expansion process are also discussed. Fill density is an important parameter for storage vessel design. Several design schemes have been proposed with some given constraints. From a standpoint of fire safety, thermal exposure before an isenthalpic expansion would increase the risk of fire, especially when the exposure temperature is very close to the hydrogen autoignition temperature.Citation
