Electrolysis for hydrogen production
Hydrogen is one of the fastest growing market segments today. It is one of the key solutions in achieving a net zero emissions economy by 2050. Hydrogen is being used to replace traditional fossil fuels in many applications, for example: fuel for heavy vehicles; a substitute for natural gas to provide heating; and as a means of storing energy.
Panametrics can play right across the hydrogen value chain, from production and transportation to utilization.
Today the majority of hydrogen is produced from natural gas in a process called steam methane reforming. This is an energy intensive process and a significant contributor to global emissions.
A second way to produce hydrogen is to separate water into its constituent parts of hydrogen and oxygen, through a process called electrolysis. If the electrolysis process is powered by renewable energy like solar or wind, you have completely emissions free hydrogen, or “Green Hydrogen”. Both the steam methane reforming and electrolysis processes need sensors to determine the quality of the hydrogen they are producing.
This is where Panametrics comes in to play. With our sensor technologies, we measure the hydrogen purity and also impurities in the hydrogen such as moisture and oxygen. Reach our team of experts to learn different technology options for the different measurements required, including thermal conductivity for hydrogen purity, electrochemical fuel cell for oxygen, aluminum oxide and laser for moisture.

While the term “the hydrogen economy” is talked about a lot right now, the reality is we have been providing measurements across the hydrogen value chain for many years.
Panametrics have been the go-to analyzer supplier of choice for many gas manufacturers on their steam methane reformer units over many years. We have long historical working relationships with electrolyzer manufacturers globally, providing products and after sales and service support for their electrolysis machines.
