LNG is a clear, colourless, non-corrosive and non-toxic liquid created when natural gas is cooled to -162ºC (-260ºF). The process of making LNG liquid begins with pre-treatment of the gas to remove impurities including water, oxygen, carbon dioxide and sulfur compounds contained in the natural gas. This results in an LNG composition of mostly methane with small amounts of other hydrocarbons. The next steps involve cooling processes to decrease the volume six hundred times, enabling the liquefied gas to be stored in highly insulated ocean-going LNG Carriers. Upon arrival at its destination, the LNG can be converted back to a gaseous state for use as an energy source or distributed in smaller volumes to other end users.
What Exactly is LNG?
Natural gas is the cleanest burning of all fossil fuels with CO2 emissions half that of coal. As it can easily replace coal and other high emissions fossil fuels, LNG has immediate value in helping committed businesses and governments meet important near-term carbon emissions targets. All major forecasts point to natural gas remaining in the energy mix for decades to come, largely due to technical and resource constraints that limit just how rapidly renewable energy projects can be ramped up. With the evolution of carbon capture technology LNG will likely be a long-term contributor to net zero goals.
