Groundbreaking, lightweight and cost-effective fuel storage, shaped to fit the vehicle

Westport™ CNG Conformable Storage technology uses multiple, connected, optimally sized chambers to create CNG fuel storage in shapes that conform to other forms of energy storage such a liquid fuels or battery packs. Westport™ CNG Conformable Storage uses conventional composite materials to produce a space efficient, tough, lightweight and low cost storage solution for CNG vehicles.

Westport is working with OEMs and Automotive manufacturing partners to produce a breakthrough in CNG fuel storage.

Benefits

35% More Fuel Stored

Up to 35% More
Fuel Stored

When compared to multiple conventional composite CNG cylinders occupying the sometimes complex spaces designated for fuel storage.
Ease of Installation

Ease of
Installation

The simplicity of a single fuel module in place of multiple, separate CNG cylinders, brackets, valves and pipes.
Lower Costs

Lower
Costs

More efficient use of carbon fibre, streamlined manufacturing process and reduction in part count builds to significant cost savings compared to conventional composite CNG cylinders.
Multi-Fuel Capability

Multi-fuel
Capability

Compatible with CNG and all forms of Renewable Natural Gas ("RNG").

Features

  • Optimized diameter, thin-wall chambers
  • Lattice packing to maximise fuel storage
  • Continuously extruded polymer liner
  • Ability to select chamber length and liner folding pattern to conform to available shape in-vehicle
  • The quantity of carbon fibre needed for a given storage volume is similar / less than conventional type IV storage
  • The carbon fibre is deposited over the liner in a multi-layer braid
  • Liner, braid and resin materials are similar to other Type IV tanks
  • The automotive supply chain can be used to manufacture the key components
  • The integral enclosure provides protection to the storage chambers

Market Opportunity

Enables compressed natural gas vehicles to retain full utility while providing customers with the driving range they need in an economic and lightweight package.

CNG vehicles with Westport™ CNG Conformable Storage become more attractive to customers and OEMs.

Can be combined with all available CNG engine technologies to provide significant savings in terms of Green House Gas and localized pollutants.

Supports widespread deployment of natural gas vehicles. Natural gas is a clean-burning low carbon fuel, which results in 25% lower CO2 emission per unit energy output when burned compared with gasoline and diesel fuel under conditions of complete combustion. Natural gas also enables vehicles to achieve lower levels of Criteria Air Contaminants (CAC) such as oxides of nitrogen, non-methane hydrocarbons particulate emissions*.
