A fuel delivery system and method for reducing the likelihood that a fuel tank of equipment at a well site during fracturing of a well will run out of fuel. A fuel source has plural fuel outlets, a hose on each fuel outlet of the plural fuel outlets, each hose being connected to a fuel cap on a respective one of the fuel tanks for delivery of fuel to the fuel tank. At least a manually controlled valve at each fuel outlet controls fluid flow through the hose at the respective fuel outlet.

A liquid direct injection assembly includes a direct injection supply kit to mix liquid components into a mixture and deliver the mixture to a treatment device. The supply kit includes one or more liquid component containers that each include an elongated flexible bladder and a discharge nozzle to discharge a corresponding liquid component from the bladder. The supply kit also includes one or more metering bodies each defining a metering orifice to control a flow rate of the corresponding liquid component from the bladder. The liquid direct injection assembly also includes a container tray configured to removably support a liquid component container.

An applicator system for extrusive dispensing of work material from a flexible pre-charged portion of a cartridge unit is provided. The system comprises a body portion having an actuator and a housing coupled thereto. The housing includes a cartridge bay and an arresting member displaceably coupled thereto. The cartridge bay is configured to receive the cartridge unit and defines at least one containment compartment for receiving the pre-charged cartridge. The arresting member is displaceable between open and closed configurations for releasably retaining the cartridge unit. The actuator, coupled to the housing in communication with the cartridge bay, includes a drive member engaging the pre-charged cartridge within the containment compartment. The body includes a handle and an activation member coupled thereto. The activation member is coupled to the actuator to selectively activate displacement of the drive member within the containment compartment responsive to user manipulation thereby compressing the pre-charged cartridge therein.

A distribution station includes a mobile trailer, a pump on the mobile trailer, at least one manifold on the mobile trailer and fluidly connected with the pump, a plurality of reels on the mobile trailer, and at least one fluid storage tank extending under the reels. A plurality of hoses are connected with a different one of the reels. A plurality of valves on the mobile trailer are situated between the at least one manifold and a respective different one of the reels. A plurality of fluid level sensors are associated with a different one of the hoses, and a controller is configured to individually open and close the valves responsive to the fluid level sensors.

A hydrogen refilling station for filling tanks of fuel cell electric vehicles includes a liquid hydrogen tank that feeds liquid hydrogen to an upstream end of a filling circuit that also includes a heat exchanger. The heat exchanger exchanges heat between the liquid hydrogen and heat transfer fluid flows to thereby cool the heat transfer fluid and vaporize the liquid hydrogen to provide a supply of high pressure hydrogen gas for filling hydrogen-fueled vehicle tanks at a downstream end of the circuit. Because the liquid hydrogen is surrounded by the heat transfer fluid inside the heat exchanger, little if any fogging occurs.
