Instrumentation and gas analysis for hydrogen

< return to the range

Hydrogen plays an important role in the production of cleaner energy. Various reliable measuring and analysis instruments (gas analysers, pressure, flow and temperature measurement) help to improve the production process. They also reduce production costs and increase the service life of the installations


Measuring instruments and gas analyzers for the hydrogen industryFuji Electric measuring instruments support professionals in the hydrogen industry during each phase of their production process in order to:

  • Reduce production cost
  • Increase yields
  • Extend the service life of installations
  • Guarantee the quality of the finished product




New generation energy system based on electricity and hydrogen. Hydrogen and electricity are convertible to each other. It is expected to establish an environmentally friendly energy cycle by using them.

Hydrogen energy characteristics:

  •  Exists everywhere on earth
  •  Generates water only when burnt
  •  Offers great power while unlikely to spontaneously ignite
  •  Serves as an energy storage medium
  •  Quick diffusion when wet


Hydrogen production

 Production methodRaw materialsEnergyFeaturesDescriptionInstruments
Conventional  technologySteam reformingWater MethaneHeatCheapest method, account for 90% of world's H2 production, emits CO2Hydrocarbon and water vapor are heated in the presence of catalyst. H2 or mixture of CO and H2 are
obtained. Light hydrocarbons such as methane, LPG, naphtha are used as raw materials. These materials needs to be desulfurized before use.

Future technologies

Coal gasificationCoal
(fossil fuel)
High-density H2
Low-quality coal waste
Carbon injected into a furnace reacts with O2 in the air to be CO2 and/or CO, or reacts with water vapor
to be CO and H2. The obtained CO goes through
reaction with water vapor, it is dissolved into CO2 and H2.
CO + H2O -> CO2 + H2
