Hydrogen Refueling Route Control for Well-to-Wheel Emissions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hydrogen production processes release carbon oxides and other pollutants, and hydrogen fuel consumption in internal combustion engines does not produce harmful exhaust, but the overall well to wheel emissions can be high due to production processes.
Innovation Solution
A system and method for routing vehicles to hydrogen refueling stations based on well to wheel emissions values, auditing fueling events, and implementing controls to reduce emissions by rerouting or modifying vehicle operations.

1Object-generated harmful factors
If vehicles are routed to specific fueling stations based on emissions criteria, then well to wheel emissions are reduced, but route complexity and travel time increase
Solution Approach 1:
The routing system performs multiple functions simultaneously: it calculates optimal routes, identifies fueling stations meeting emissions criteria, and provides guidance to drivers. By integrating these functions into a single comprehensive system, the patent reduces the time and complexity associated with separate emissions assessment and route planning processes.
2Reliability
If refueling events are audited and controls are implemented, then emissions compliance is improved, but system complexity and operational overhead increase
Solution Approach 1:
The system implements feedback mechanisms where actual refueling events are monitored and compared against expected emissions values. When discrepancies are detected (such as refueling at a station with higher emissions than anticipated), the system provides feedback by modifying routes to exclude problematic stations or implementing controls to prevent future occurrences, thereby maintaining emissions compliance through continuous monitoring and adjustment.

AI summary
A system includes a processing circuit configured to receive route information comprising a route of a first vehicle; receive a target well to wheel emissions value associated with at least the first vehicle; receive a first well to wheel emissions value regarding a first available fuel; comparing the first well to wheel emissions value to a predetermined threshold, the predetermined threshold based on the target well to wheel emissions value; identify a first fueling station associated with the first available fuel responsive to the first well to wheel emissions value being below the predetermined threshold; and modify the route of the first vehicle to include the first fueling station responsive to identifying the first fueling station.
