An interface system extends a prior-art fuel delivery pump and reservoir so that authorization to activate the fuel delivery pump can be obtained from a remote authorization service over a long-range wireless communication link such as a cellular telephone connection or a satellite connection; and delivered to the interface system over a different, short-range wireless communication link such as a Bluetooth connection or a WiFi connection. The system is structured so that different data link devices can serve in one part of the communication chain. Asynchronous methods allow the system to operate securely when a data link device is not able to provide a synchronous link at a time when fuel dispensing is desired.

Various systems, devices, and methods are provided for facilitating communication between a forecourt controller and a fuel dispenser. In certain aspects, a fuel controller translator is provided for translating commands transmitted between the forecourt controller and the fuel dispenser. For example, where the forecourt controller transmits commands that are compatible with the payment terminal, but not with the fuel controller, the fuel controller translator can translate the commands received from the forecourt controller into a format compatible with the fuel controller. Conversely, the fuel controller translator can translate commands received from the fuel controller into a format that is compatible with the forecourt controller.

A system detects a fuel dispensing operation that indicates fuel is being dispensed from the fuel dispensing terminal. The system determines an identifier value associated with a volume of fuel dispensed from the fuel dispensing terminal. The system determines a measured volume per unit time parameter associated with the fuel dispensed from the fuel dispensing terminal by dividing the determined identifier value by a unit parameter. The system compares the measured volume per unit time parameter with a threshold volume per unit time parameter. In response to determining that the measured volume per unit time parameter is less than the threshold volume per unit time parameter, the system communicates an electronic signal to the fuel dispensing terminal that instructs the fuel dispensing terminal to stop dispensing fuel.

Systems and methods for regulating fuel at a power plant are provided. One example aspect of the present disclosure is directed to a method for regulating fuel at a power plant. The method includes receiving data from an engine. The engine includes an A-ring, a B-ring, and a C-ring. The method includes updating a plurality of models based on the received data. The method includes predicting a plurality of outputs using the plurality of models for a plurality of fuel splits. Each fuel split includes a fuel amount associated with the A-ring. Each fuel split includes a fuel amount associated with the C-ring. The method includes selecting an actual fuel split based on the plurality of outputs.

An acquisition portion obtains the daily gas consumption amount of a tank from a gas meter. A consumption amount predicting portion predicts future daily gas consumption amounts for the set number of days using the latest gas consumption amount having the same day of the week among the gas consumption amounts obtained by the acquisition portion. A replacement day predicting portion, as a remaining amount predicting portion, predicts the remaining gas amount in the tank using the gas consumption amounts obtained by the acquisition portion and the future gas consumption amounts for the set number of days predicted by the consumption amount predicting portion.

Aspects of the disclosure are directed to an optimization model for storing liquid hydrogen to power fuel cells in data centers. The optimization model can be based on hydrogen fuel consumption rates in the data center, refueling rates from vendors, refueling response time, storage tank area constraints in the data center, and/or logistical refueling constraints. The optimization model can allow for providing sufficient fuel within a constrained space for backup power in the data center, such as when an emergency arises.

A method for enhancing a LNG production train that includes connected train components. The method may include steps of: constructing an integrated surveillance system for monitoring operation of the train components; using the integrated surveillance system to measure and record operational data and event data related to, respectively, the operation and a failure event of the train components over a historical operating period; performing a correlation analysis that calculates a correlation between the occurrences of the failure event and the operational data; given results of the correlation analysis, deriving a prognostic rule that indicates a likelihood of the failure event occurring based on values of the operating parameters of the operational data; applying the prognostic rule to current values of the operating parameters and determining therefrom the likelihood of the failure event occurring; determining an advisory related to the determined likelihood of the failure event occurring; and issuing the advisory.

A fuel system controller obtains fuel burn data from an engine control module (ECM). The fuel system controller also obtains location data from a telematics control module, such as GPS location data identifying the location of a vehicle. The fuel system controller determines the vehicle's base location based on the location data, and determines how far the vehicle can travel based on the fuel burn data. The fuel system controller determines how many fueling stations are with a threshold distance of the determined distance to empty. The fuel system controller can use that data to identify which, and how many, fueling stations are within a threshold distance of the determined distance to empty. The fuel system controller can provide a fueling warning indication based on the number of fueling stations that are within the determined distance to empty.
