Abstract: A method of filling a hydrogen-storage tank with a metal-organic framework (MOF) includes inserting MOF through an opening of the hydrogen-storage tank to at least partially fill an interior cavity of the tank with MOF. The method further includes positioning a compactor relative to the tank. The compactor includes a tamp configured to change shape between an insertion state in which the tamp is insertable through the opening and an expanded state in which the tamp is enlarged to be bigger than the opening. The method also includes inserting the tamp through the opening when the tamp is in the insertion state and switching the tamp from the insertion state to the expanded state. The method further includes compacting the MOF with the tamp.

Abstract: A pressure vessel includes a shell, a first boss, a second boss, and a reinforcement support. The shell defines an internal cavity. The first and second bosses are disposed within the cavity and respectively extend through opposing longitudinal ends of the shell. The first boss defines a longitudinally extending central orifice. The reinforcement support is disposed within the cavity, is secured to the first boss radially outward of the central orifice, extends from the first boss to the second boss, and is secured to the second boss.

Abstract: Methods of forming a high surface area compacted MOF powder are disclosed, as well as MOF pellets formed thereby. The method may include synthesizing a metal organic framework (MOF) powder using a first solvent, exchanging the first solvent with a second solvent such that pores of the MOF powder are at least 10% filled with the second solvent, compacting the MOF powder having pores at least 10% filled with the second solvent into a pellet, and desolvating the compacted pellet to remove the second solvent. The pellet may maintain a specific surface area after compacting that is at least 80% its initial specific surface area. Compacting the MOF powder with a solvent at least partially filling its pores may prevent or reduce crushing of the MOF pore structure and maintain surface area, for example, for hydrogen or natural gas storage.
