Design of portable hydrogen tank using adsorption material as storage media: An alternative to Type IV compressed tank

•Portable hydrogen tank using absorption material is considered as an alternative to Type IV compressed tank.•Light-weight, high-capacity and cost-effective hydrogen storage tank is presented for automobile applications.•Three-layer thermal insulation effectively maintains cryogenic temperature for long time.•FEM equivalent conduction model with surface-to-surface radiation is used for heat ingress estimation.•Estimation procedure for futuristic capacity of hydrogen storage system is established. With recent breakthroughs in hydrogen storage in porous materials, this paper presents design concept of portable hydrogen tank that use material-based storage technique at low pressure and cryogenic temperature. The tank is portable to use in applications such as Fuel cell electric vehicles (FCEVs) due to the effective three-layer insulation feature which is able to maintain cryogenic temperature for at least 12.5 days without need of external cooling loop. The portable tank can be employed with a variety of porous absorbents with storage conditions of 77 K and
