The most heard statement when energy is discussed is that Hydrogen is the future. But how will you safely handle Hydrogen gas detection, and what is Hydrogen (H2) actually? The use of Hydrogen for industrial and maritime purposes has grown significantly over the past 20 years. And with the increasing demand for energy and the global road to emissions reduction, Hydrogen will be there to stay.
But with the growth of Hydrogen implementation, hazardous gas makes its way into the business. How should you control and handle this gas, and how should you perform gas detection of Hydrogen?
Used as a fuel, Hydrogen is extremely flammable, so when a Hydrogen leak occurs, a severe risk of ignition presents itself. However, Hydrogen fires are unlike fires involving ‘traditional’ fuels. When weightier fuels and hydrocarbons, like petrol or diesel, leak, they stay close to floor level.
While on the Hydrogen-side it makes one of thelightest elements on earth, so in the event that a Hydrogen leak occurs, Hydrogen rapidly levitates upwards. This fast levitation makes ignition less likely, but another difference is that Hydrogen ignites and burns more efficiently than petrol or diesel. That’s kind of the big downside of the gas… Even a spark of static electricity of a human finger is sufficient to cause an explosion when Hydrogen is in the air.
Hydrogen gas is odourless, colourless and tasteless. The gas is non-toxic, but in indoor environments, Hydrogen may build up and cause suffocation by removing all the oxygen. This danger of suffocation can be offset by adding odorants to hydrogen fuel, giving it an artificial smell and warning bystanders in case of a leak.
But as Hydrogen disperses quickly, the odorant is unlikely to travel with it. Hydrogen leaking indoors quickly collects at the ceiling level and eventually fills the room. For that reason, implementing Hydrogen gas detection with the therefore-suited gas detectors is critical in the early detection of a hydrogen leak.
Working with Hydrogen does not come without risks. However, the gas can be used safely when the proper repercussions are looked after. Facilitating gas detection provides a safe working environment for both the company and its employees. Regardless of whether this isportable gas detectionorfixed gas detection.
A fundamental principle of handling Hydrogen is the ability to quickly and reliably test for its presence during regular inspections and if there is any reason to question that a leak has developed.
Hydrogen gas detectors commonly use several mechanisms to determine the presence and concentration of Hydrogen, including diffusion type, sample draw, gas chromatography, mass spectrometry, catalytic bead, and thermal conductivity.
Choosing the correct Hydrogen gas detector for your environment often means understanding each gas detector’s features and the environmental conditions where it will be in use. Before selecting a hydrogen detector, several functional parameters should be considered:
So, where does that leave us when considering hydrogen gas detector calibration? Regularcalibration of the gas detectorsis required to guarantee the safety of your surroundings. Respect the manufacturer’s calibration interval to guarantee optimal detection.
