The Chinese discovered the fuel in wells drilled from salt brine pools in 900 B.C. Natural gas made its first big impact on the public in 1807 when gaslights lit up the streets of London. Today, natural gas is a heating fuel and powers 50,000 vehicles in the U.S. and almost 1 million vehicles worldwide. LNG is stored under pressure at such cold temperatures it liquefies. Fast-fill fueling is like conventional fueling and delivers fuel to the vehicle in just a few minutes. With mobile-fueling , fuel is partially compressed on a tube truck.
Compression is completed as the fuel is delivered to the vehicle.
Home-dispenser fueling systems connect directly to the home's gas line. More than 1,000 natural gas fueling stations are located in major cities and transportation corridors nationwide. LNG is available through cryogenic liquid suppliers. The range of most CNG vehicles is about half that of gasoline-fueled vehicles. The power, acceleration, payload and cruise speed of natural gas vehicles are comparable to equivalent internal combustion engines.
