Hydrogen Recovery Buffer for Refueling Station Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hydrogen refueling station evaluation devices waste hydrogen by discharging it to the atmosphere during purging, and require additional manpower and costs for relocating the device for discharge, which increases overall evaluation costs.
Innovation Solution
A waste hydrogen recovery device is implemented, featuring a buffer container connected to the discharge pipeline, a flow path switching valve, and a controller that directs hydrogen from the buffer container back to the refueling station using the compressor, minimizing atmospheric discharge and eliminating the need for manual relocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hydrogen is discharged to the atmosphere from the evaluation device, then hydrogen purging is achieved, but hydrogen is wasted and additional costs for relocation are incurred
Solution Approach 1:
The patent recovers hydrogen that would otherwise be discarded to the atmosphere by connecting the evaluation device's discharge pipeline to the hydrogen refueling station's supply pipeline through a buffer container, allowing the refueling station to reuse the purged hydrogen for refueling operations
Solution Approach 2:
A buffer container is introduced as an intermediary component between the evaluation device and the hydrogen refueling station, serving as a temporary storage vessel that enables the transfer and recovery of hydrogen while pressure equalization occurs
2Reliability
If the evaluation device is moved to a place for hydrogen discharge, then hydrogen can be discharged to the atmosphere, but additional manpower and costs are required
Solution Approach 1:
The hydrogen refueling station itself serves as the discharge destination by directly receiving hydrogen from the evaluation device through pipeline connection, eliminating the need to relocate the evaluation device to a separate discharge location
3Loss of substance
If the buffer container pressure is reduced to recover hydrogen, then hydrogen can be transferred to the refueling station, but pressure difference must be controlled
Solution Approach 1:
The system controls the pressure parameter of the buffer container by opening the discharge valve to reduce pressure difference, enabling hydrogen flow from the evaluation device to the refueling station while maintaining safe operating conditions
