Hydrogen purity management oxygen concentration meter

Introduction of measurement instruments for hydrogen purity management used in dehydrogenation processes and hydrogen addition.

Hydrogen is used in fuel cells and various chemical and industrial fields. It is not commonly found as a gas in our surroundings; most of it exists as water and is produced through methods such as electrolysis of saltwater and alkaline water electrolysis. On the other hand, it can also be produced from renewable energy sources and is considered a focus of energy efforts related to the SDGs. Typically, hydrogen is transported in a high-pressure or liquefied state, but technological innovation for transporting it from supply locations to demand locations is essential. One method to improve efficiency is to transport it as methylcyclohexane (MCH), which has a volume 1/500th that of gaseous hydrogen and can carry hydrogen at room temperature and pressure. The processes of extracting hydrogen from MCH (dehydrogenation) and adding hydrogen to toluene require purity management of the hydrogen, for which oxygen concentration meters and dew point meters are used. *MCH: A type of hydrogen carrier (hydrogen storage medium). Since MCH and toluene are classified as hazardous materials of the same category as gasoline (Class 4, Category 1 petroleum), the risks associated with storage and transportation are reduced to levels comparable to petroleum products. The hydrogen produced will be used in fuel cells and new fields.
