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.

Device and method for filling pressurized gas tanks, particularly vehicle pressurized hydrogen tanks, the device comprising a liquefied gas source, a transfer circuit comprising two parallel transfer lines each having an upstream end linked to the liquefied gas source, at least two separate downstream ends intended to be each removably connected to a tank to be filled, each of the two transfer lines comprising: a pump, a vaporizer for evaporating the pumped fluid, a branch for bypassing the vaporizer and a distribution valve(s) set configured to control the flow of fluid pumped and distributed between the vaporizer and the branch line, the device further comprising a storage buffer(s), which storage buffer(s) is(are) connected in parallel to each of the two transfer lines via a set of valves.

Fuel dispenser (100) comprising: a fluid inlet (105IN) for receiving fuel from a fuel source, a fluid outlet (105OUT) and a conduit (110) disposed therebetween; inspection means (152) for inspecting the fuel within the conduit (110), the inspection means (152) being configured to provide an output indicative of a type of fuel in the conduit (110); valve means (120) operable selectively to prevent or allow flow of fluid through the conduit (110) from the fluid inlet (105IN) to the fluid outlet (105OUT); and control means (150) configured automatically to cause the valve means (120) to prevent or allow flow of fuel through the conduit (110) in dependence on the output of the fuel inspection means (152) and permitted fluid information, the permitted fluid information being information indicative of a type of fuel that is to be permitted to flow through the conduit (110), the apparatus (100) comprising an electrical generator (140) configured to generate electrical power to charge a charge storage device in response to flow of fluid through the apparatus (100) during an operation in which fluid flows from the fluid inlet (105IN) to the fluid outlet (105OUT) via the conduit (110), the charge storage device being arranged to provide a supply of electrical power for the apparatus.

An electric fuel flow control device for use with oil and gas equipment, such as fueling systems for frac pumps. The electric fuel flow control device includes a battery, control circuitry, an enclosure that encloses the control circuity, and includes an electric fluid sensor, a valve, a beacon light, a status light, a button, an adapter cap enabling connection to a fuel tank, and a mandrel. The electric fuel flow control device may be used as a primary fuel flow control device or a backup fuel flow control device.

An autonomous fueling system to dispense fuel to a vehicle. The system may include a fuel dispenser configured to autonomously deliver fuel to a vehicle. A server may monitor the fueling event. The system may also include a user device configured to communicate with the fuel dispenser and/or the server to order the fuel. The dispenser may be configured to autonomously insert a nozzle into the fuel system of the vehicle and deliver the fuel.

A system comprising a plurality of ports is capable of automated, remote detection of conditions indicating that refill is required in one of a plurality of remote tanks and causing refill of the tank via at least one of the plurality of ports. Further, the system includes automated monitoring and supply of a fuel tank.

A method of delivering a fluid to a fluid consuming asset having a fluid tank is disclosed. A first tank is filled with the fluid and is fluidically coupled to a second tank which may be pressurized by a compressor. The second tank is fluidically coupled to a manifold which is in turn coupled to a fluid transporting mechanism. The fluid transporting mechanism is fluidically coupled to a hydraulic connector of a fill cap which is coupled to an opening of the fluid tank. The fluid is directed from the first tank to the second tank, the manifold, the fluid transporting mechanism, the hydraulic connector and into the fluid tank through an outlet of a probe of the fill cap.
