Hydrogen detection dystems for green hydrogen plants use a variety of technologies to monitor and analyze hydrogen gas, including:
Sensors
There are many types of sensors that can detect hydrogen, including electrochemical, catalytic combustion, semiconductor, and thermal conductivity sensors. Each type of sensor has its own strengths and weaknesses, such as sensitivity, power consumption, and response time.
Mass spectrometers
These instruments can analyze hydrogen and other gases in real time, providing accurate measurements of purity and mixed gas streams.
Flow meters
These devices measure the flow rate of hydrogen gas in various processes. Different types of flow meters include turbine, ultrasonic, and thermal mass flow meters.
Ultrasonic acoustic sensors
These sensors can detect high-pressure gas leaks by registering the sound of the leaking gas.
Internet of Things (IoT) technology
This technology integrates sensors and networks to detect gas leaks and facilitate safety management.
Hydrogen is flammable and can be dangerous if mishandled. Here are some other things to consider when detecting hydrogen:
Hydrogen is lighter than air and can accumulate from the top in enclosed spaces.
Hydrogen flames are very pale or invisible to the naked eye.
Hydrogen is odorless, so it can't be detec
ted by smell.
