Liquefied Natural Gas

The Fleet Test and Evaluation team worked with industry partners to evaluate liquefied natural gas (LNG) use in refuse haulers and transit buses.

LNG is a non-toxic, non-corrosive, and non-carcinogenic alternative fuel primarily used in heavy-duty vehicles. LNG is produced by cooling natural gas into a liquid at -260°F and storing it in double-wall, vacuum-insulated pressure vessels. Like compressed natural gas, LNG produces fewer emissions and offers fuel economy comparable to conventional fuels.

The Fleet Test and Evaluation team partnered with the following fleets to test LNG in refuse trucks and buses.
