Whats the difference between CNG and LNG?
CNG is compressed natural gas. It’s commonly used to heat homes and run appliances. On vehicles, CNG is stored similar to a car’s gasoline tank, attached to the rear, top or undercarriage of the vehicle in a tube-shaped storage tank. Today, natural gas is most commonly used in its compressed form (CNG). LNG is liquid natural gas. It has been cooled to get it into a liquid form. It takes up less space to transport and store, so is often used for longer-range applications. It’s higher energy density is also beneficial for heavier duty applications. LNG is typically transported globally via tankers and then connected to local natural gas infrastructure on land, where it’s then sold as LNG or compressed and sold as CNG.
