Systems and methods for injecting hydrogen into a natural gas pipeline to lower the carbon intensity of the resulting fuel blend while achieving the required energy output thereof for the end user. In one embodiment a blend ratio for the blended fuel comprising hydrogen and natural gas is determined based at least in part on a minimum energy output for fuel combusted at an end-use location connected to the natural gas pipeline so that the blended fuel (i) has a lower carbon intensity than a natural gas stream flowing in the natural gas pipeline, and (ii) provides at least the minimum energy output when combusted at the end-use location. Further, one or more embodiments include adjusting a control valve of a hydrogen injection assembly connected to the natural gas pipeline upstream of the end-use location based at least in part on the blend ratio to thereby mix hydrogen into the natural gas pipeline and produce the blended fuel.

A chemical delivery device for use in a vehicle wash system includes a chemical delivery device with a chemical chamber having an inlet, an outlet, and a one-way valve, and a drive mechanism with a drive shaft joined to a piston in the chemical chamber. Upon the drive mechanism driving the piston in a dispensing direction, the one-way valve is closed and chemical in the chemical chamber is pressurized and the piston causes the pressurized chemical to be dispensed from the outlet, e.g., to a vehicle wash component, and during dispensing, a vacuum is created in the chemical chamber such that a corresponding amount of the chemical to an amount dispensed is drawn into the chemical chamber from a chemical supply via the chemical inlet. Upon the drive mechanism retracting the piston in a resetting direction, the one-way valve is open and permits passage of fluid therethrough for subsequent dispensing.

A vehicle wash assembly for distribution of fluids at a vehicle wash location includes a vehicle wash component operable to dispense fluid into a fluid line for application onto a vehicle by a downstream applicator, and an inlet or outlet of the vehicle wash component is associated with a port configured with an adjustable effective orifice area. A control system receives instructions corresponding to timing information, a target flow rate and/or a target volume of the fluid to be dispensed from the outlet, analyzes the instructions, and generates separate instructions that differ from those received. The separate instructions include a time for when the vehicle wash component is to be actuated, a duration of operation upon actuation, and an effective orifice area of the port. Upon transmission, the separate instructions cause the vehicle wash component to dispense the fluid according to such instructions during a dispensing operation.
