Clean Transportation for a Sustainable Future - Infographic on CNG LNG Hydrogen - Parker HannifinOf the many transport fuel choices available today, none plays a more strategic role than natural gas in having an immediate and major positive economic and environmental impact. But of the two most widely available – CNG and LNG – which is most appropriate?

 

 

 

Onboard vehicle filling stations  - Compressed Natural Gas

Compressed Natural Gas (CNG ) is a fuel produced by purifying natural gas and cooling it to less than 1% of its volume and stored onboard a vehicle in a compressed gaseous state at a pressure of up to  3600 PSI. CNG is used in light-, medium, and heavy-duty vehicle applications.

 

Gas transport and storage - Liquidized Natural Gas

LNG is a fuel produced by purifying natural gas and cooling it to -161°C to turn it into a liquid. LNG is suitable for trucks that require longer ranges and typically used in heavy-duty vehicles. Parker Bestobell’s cryogenic valves are widely used on road LNG trucks transporting LNG to fueling station sand storage tanks. 

 

On-board vehicle filling station - Hydrogen 

Hydrogen can be produced from fossil fuels, biomass, and water electrolysis with electricity. The environmental impact and energy efficiency of hydrogen depends on how it is produced. Hydrogen-powered vehicles work by converting compressed hydrogen from their fuel tanks into electricity that powers their engines. This process generates only water vapor and heat emissions.

 

Solutions

  • Fittings and tubing - Parker’s A-LOK® two ferrule fittings, CPITM single ferrule fittings and tubing provide reliable leak-free tube connections on-board CNG vehicles and at fueling stations. The unique SuparcaseTM hardened ferrule design provides superior grip and safe lifetime operation.
  • CNG valves and pressure regulators - Parker’s high integrity precision ball valves Hi-Pro® and B Series, check valves and pressure regulators provide safe isolation, regulation and control onboard CNG vehicles and at fueling stations. 
  • Fuel regulation module - Parker’s integrated gas regulator system, FM80 provides advanced fuel handling performance. Piston regulator design delivers better control, fewer connections, and longer range.
  • Cryogenic safety relief valves - Parker Bestobell’s cryogenic safety relief valves are designed to protect LNG storage tanks or capital equipment on road-going transport trucks from damage caused by over-pressure.
  • LNG Cryogenic check valves - Parker Bestobell’s cryogenic check valves with innovative loose flange bolted bonnet design allow for thermal expansion and contraction eliminating leakage and maximizing safety and performance.
  • Cryogenic globe valves - Parker Bestobell’s cryogenic globe valves deliver smooth operation and reduced closing torque by use of a PTFE anti-friction disc between the valve spindle and the disc assembly.
  • Fittings - Parker’s A-LOK® two ferrule fittings up to 1” size provide reliable leak-free tube connections onboard hydrogen-powered vehicles and at fueling stations. The unique SuparcaseTM hardened ferrule design provides superior grip and safe lifetime operation. EC-79 approved.
  • Medium pressure valves - Parker Autoclave Engineers needle valves, check valves, filters utilize a coned-and-threaded connection design providing a leak-tight reliable connection at fueling stations in applications up to 20,000 PSI and temperatures from -73° to 316°C.
  • Medium pressure tubing and fittings - Parker Autoclave Engineers medium pressure cone & thread fittings provide reliable leak-free and safe lifetime operation at fueling stations.
