Traditional detection methods often fall short, particularly
in critical infrastructures where even minor leaks can pose
signi昀椀cant safety risks.
Environmental bene昀椀ts
The technology's ability to capture leaks enhances safety
and protects the environment by preventing potential
hydrogen emissions into the atmosphere, which several
prominent environmental groups have shown could be an
indirect greenhouse gas, thereby leading to growing scrutiny
over hydrogen's diverse environmental impact.
Understanding the application of hydrogen
sensors
Hydrogen presents unique safety challenges, while being
an environmentally friendly alternative to fossil fuels. Its
flammability and propensity to leak undetected through
conventional materials and tiny openings require specialised
monitoring techniques.
Traditional detection methods often fall short, particularly
in critical infrastructures where even minor leaks can pose
significant safety risks. Existing sensor technologies
include sensors that require a reference gas, consumable
components, or periodic calibration. Frequent sensor
maintenance is not practical in pipeline applications where
the sensors may be located on buried pipeline across
hundreds of miles in remote areas.
For this system, the engineers selected H2scan's solid-state
sensor to provide real-time continuous measurement of
hydrogen levels. The sensors detect hydrogen speci昀椀cally
without cross-sensitivity to other gases. An auto-calibration
capability eliminates the need for periodic maintenance.
The sensor does not require a reference gas or consumable
components.
Conclusion
H2C Safety Pipe technology may represent a signi昀椀cant
advance for hydrogen distribution. By addressing safety
concerns, leveraging existing infrastructure, lowering cost,
optimising efficiency, and facilitating the transport and
distribution of hydrogen, the double-wall safety pipe
approach promises a smoother transition towards a
hydrogen-based economy.
As the hydrogen economy continues to evolve, the role of
advanced technologies becomes increasingly vital. Sensors
must provide accurate, real-time monitoring of hydrogen
levels to detect leaks, ensure safety, enhance operational
e昀케ciency, and support the widespread adoption of hydrogen
across diverse applications - from transportation to industrial
processes and beyond. Sensors are the enabling technology
that will help the global community realise the vast potential
of hydrogen as a transformative, clean energy solution.
Figure 2. A hydrogen sensor, the HY-OPTIMA® 5031 from
H2scan, is located in the annulus between the inner and outer
carrier pipes. If the sensor detects that unsafe levels of hydrogen
gas have leaked into this space, then a control system
automatically initiates a purge of the annulus with an inert gas.
