Methane Gas

Uses & Applications

Fuel

Methane is used in a wide range of fuels, including natural gas, liquefied natural gas, power-to-gas, and liquid methane rocket fuel. Typically transported in its liquid form due to liquid methane is about 1/600th the volume of gaseous methane due to its higher density.

Chemical

Used for feedstock for synthesis gas production.

Additional Uses & Applications

  • Calibration gases for methane analyzers (NDIR/laser), LEL sensor bump tests, and atmospheric monitoring

  • Etch/reaction gas components (e.g., CH4/H2/Ar) for III-V and wide-bandgap semiconductors

  • CVD/PECVD carbon source for diamond, DLC, and graphene growth

  • Detector/counting gases, including P-10 (90% Ar / 10% CH4) and Ar/CH4 95/5 for proportional counters and drift chambers

  • Combustion, burner, and engine/turbine R&D; emissions and calorimetry studies

  • Furnace atmospheres as a carbon donor for carburizing/carbonitriding of steels

  • Catalysis and kinetics research; controlled hydrocarbon feed in pilot plants

  • Feedstock for hydrogen/syngas via steam-methane reforming (R&D and pilot scale)
