Abstract: An apparatus and process for dispensing a cryogenic fluid (e.g. a cryogenic liquid, liquid hydrogen, liquid natural gas, etc.) can include feeding liquid from a storage tank to one or more dispenser feed vessels, subsequently pressurizing the vessel(s) with gas to a pre-selected dispending pressure, and then outputting the liquid from the dispenser feed vessel(s) to one or more dispensers. After dispensing is complete, fluid from within the vessel(s) can be displaced and used for other processing. Embodiments can be configured to help limit or avoid venting while also providing improved operational flexibility and efficiency.

Abstract: An apparatus and process for warming a cryogenic liquid and re-cooling gas for recapture and recovery of that cryogenic gas can include recovery cryogenic gas and storing that gas in at least one storage device to avoid venting such gas to atmosphere. The stored gas can be fed to at least one heat exchanger to vaporize a cryogenic liquid being fed from at least one storage tank for dispending of that cryogenic fluid. The stored cryogenic gas can be cooled as a result of its use as a heating medium for vaporization of the cryogenic liquid and can be subsequently fed to one or more cryogenic liquid storage tanks as a cooled cryogenic gas, partially liquefied fluid that includes cryogenic liquid and cryogenic gas, or a fully liquefied cryogenic liquid for storage and subsequent use.

Abstract: An apparatus and process for fog mitigation can be include a mechanism to reduce fog formation and/or condense the fog into water to avoid fog being formed and moving through a site. Embodiments can be configured to utilize at least one fog collection mechanism positioned adjacent a vaporizer utilized to vaporizer a cryogenic liquid so that fog that may form adjacent the vaporizer is removed from air surrounding the vaporizer and prevented from spreading beyond the vaporizer to other areas of a site having the vaporizer (e.g. a hydrogen fueling station, etc.).
