Using natural gas to fuel vehicles reduces greenhouse gas emissions by up to 30% versus conventional liquid fuels.

LNG vs Diesel - cheaper, greener, quieter

LNG vs CNG - lower weight, smaller footprint, easier to install, faster fill times

LNG fuel systems are optimal for heavy-duty vehicles requiring significant fuel capacity. LNG is vaporized during engine operation, in a vaporizer heated by the engine’s cooling system, while a pressure regulator controls the delivery of gas to the vehicle’s engine and maintains a constant pressure. The systems consist of one or more super-insulated fuel tanks, ensuring long-time, on-board storage and loss-free operation.

Typical vehicles include LNG powered high horsepower trucks, buses and mine haulage trucks.
