AI Technical Summary
Hydrogen presence can degrade metal components and reduce the effectiveness of optical fibers used in systems like oil and gas recovery, fluid sequestration, and hydrogen transport by darkening and reducing signal strength, necessitating a method to detect hydrogen presence, quantity, and history.
A method and system using an optical fiber to measure temperature and signal loss profiles, comparing calibrated and measured characteristics to determine hydrogen partial pressure, employing OTDR and DTS to differentiate temperature and hydrogen-induced signal changes.
Accurately detects hydrogen partial pressure and presence, enabling preventative measures against degradation and failure in systems like boreholes, pipelines, and hydrogen storage facilities.
