Liquefaction: cooling down natural gas

LNG is a cold, liquid version of natural gas. As the gas is cooled down to -162°C (-259°F), it changes from a gaseous to a liquid form, and we then know it as LNG. And unlike the gas, this liquid is easy to transfer to tanks and move around. Naturally, turning the gas into a liquid fuel involves more than just turning down the temperature, but the cold is an essential part of the liquefaction process.
