As the name suggests, liquefied natural gas (LNG) involves turning gas into liquid form — a process known as liquefaction. Liquefaction does not alter the chemical makeup of gas, which is comprised of mostly methane plus varying amounts of different impurities, but it does make it denser. This enables ships and other carriers to move more gas over oceans between locations that lack direct pipeline connectivity.
