Natural Gas

It may drive like a petroleum-powered vehicle, but it certainly doesn’t sound like one.

Natural gas, traditionally used to power homes and businesses, can also be used for cars and trucks. Natural gas produces fewer emissions than conventional diesel and gasoline-fueled vehicles and runs quieter as well. With a wide distribution network across the country, natural gas is readily available for fleet users and consumers alike.

Drivers can find natural gas in two forms – liquefied and compressed. Liquid natural gas (LNG) needs to be cooled to temperatures below -260°F but packs a lot of punch, making it particularly useful for long-range vehicles. Compressed natural gas (CNG) is used more widely and can be seen across the Puget Sound region, including trucks, buses and taxi cab fleets. Some natural gas vehicles, called bi-fuel NGVs, can operate on both natural gas and petroleum-based gasoline.

Renewable natural gas: turning trash to cash

Renewable natural gas (RNG), also known as biogas or biomethane, comes from gas produced during the natural breakdown of organic waste. Due to its renewable nature, biogas is extremely climate-friendly, releasing the lowest amount of greenhouse gas emissions of any commercially-available vehicle fuel. Sewage, agricultural waste and landfills are all potential sources of biogas, which can be used to heat buildings and fuel natural gas-ready vehicles. Landfills in particular can generate an astonishing amount of energy. For example, King County’s Cedar Hills Regional Landfill produces enough biogas to equal nearly 40,000 gallons of gasoline each day!
