Abstract: A system for hydrogen dispensation can include: a hydrogen collector; a cryo-compressed buffer storage system; and a hydrogen dispenser. The system functions to facilitate hydrogen fueling/dispensation (e.g., rapid dispensation) while additionally utilizing hydrogen storage in a cryo-compressed hydrogen state. The system and/or method may be implemented in any general use case that requires hydrogen storage and/or hydrogen refueling.

Abstract: The system can include: a heat exchanger, a set of valves, a sensor suite, and a controller The system can optionally include or be used with a catalyst, a set of barriers, and/or an enclosure. However, the system can additionally or alternatively include any other suitable set of components. The system functions to facilitate cooling of a pressurized fluid (e.g., high pressure hydrogen gas). Additionally or alternatively, the system can function to catalyze fluid state change (e.g., hydrogen spin conversion, etc.) within the pressurized fluid. For example, the system can be used to convert hydrogen from a high-pressure gaseous hydrogen (GH2) state or high-pressure supercritical hydrogen (ScH2) state to the cryo-compressed hydrogen (CcH2) state without hydrogen liquefaction (fluid state transition to liquid hydrogen, LH2).

Abstract: The pressure vessel system can include a pressure vessel and an optional jacket. However, the system 100 can additionally or alternatively include any other suitable set of components. The pressure vessel can include a liner, an optional composite overwrap, and/or any other suitable components. For example, the pressure vessel can be a composite overwrapped pressure vessel (COPV) with a metallic liner (e.g., alloyed aluminum). The pressure vessel system can function to store fluid (e.g., cryo-compressed hydrogen) within an interior chamber.

Abstract: A system and method for operation for cryo-compressed hydrogen storage can include: an inner pressure vessel that includes an inner liner with a defined inner volume configured for para to ortho conversion of gaseous hydrogen before venting; an insulation layer, situated outside the inner pressure vessel; an outer wall; and a support structure situated between the inner pressure vessel and the outer wall.

Abstract: In one aspect, an insert including a single metal or alloy compatible with cryo-compressed tanks is disclosed. In one embodiment, the insert contains one, two, or more tubes that extend into the inner storage volume of the tank. The insert may be integrally formed with the tubes. The tubes enable the entrance and exit of hydrogen to the inner storage volume. In one embodiment, the tank includes a boss suitable to accept the insert. The boss and the insert may be the same metal. The insert may minimize the number of welds suitable for use in on-board heavy duty storage applications. Overall, this type of insert decreases the probability of hydrogen leaks, reduces the cost of the insert as only one piece is required, and leads to faster manufacturing as fewer welds are required.

Abstract: A method of operating a cryo-compressed storage system is disclosed. The system includes a plurality of cryogenic tanks adapted to store a supply of hydrogen. The method includes dividing the hydrogen into a plurality of portions, storing each of the portions in respective first and second cryogenic tanks of the plurality of cryogenic tanks; withdrawing at least part of a first portion of the plurality of portions from the first cryogenic tank; responsive to the first cryogenic tank containing a remainder of the first portion, such that the first respective cryogenic tank is at least partially depleted, withdrawing a first amount of hydrogen of the second portion from the second cryogenic tank; heating, via a heater external to the plurality of cryogenic tanks, the first amount of hydrogen; and providing the first amount of hydrogen to the first cryogenic tank such that the first amount of hydrogen heats the remainder.

Abstract: A permanently porous vanadium(II)-containing metal-organic framework (MOF) with vanadium(II) centers and methods for synthesis of such MOF frameworks are provided. Methods for using such compounds to selectively react with N2 over CH4 are provided. In the synthetic methods, a vanadium source, such as VY2(tmeda)2, where Y is a halogen and tmeda is N,N,N?,N?-tetramethylethane-1,2-diamine and a H2(ligand) are reacted in the presence of acid in a solvent at between 110° C. and 130° C. to form an intermediate product. The intermediate product is collected and washed with a washing agent, such as DMF and acetonitrile, and the vanadium(II) based MOF is activated by heating the washed intermediate product to at least 160° C. under dynamic vacuum.
