Liquefied natural gas (LNG) is a natural gas in its liquid state. When natural gas is cooled to a temperature of about minus 160° C (minus 260° F) at atmospheric pressure, it becomes a clear, colourless and odourless liquid. LNG is clean, efficient and safe. It can be easily stored and economically transported for use as a low-carbon fuel. LNG is an accessible source of energy for communities in geographical locations that prevent them from connecting to main gas networks. It is a less expensive source of energy for heating fuel and power generation.
For the North Shore communities of Lake Superior, LNG has the potential to bring significant social, economic and environmental benefits for residents and businesses.
Small-scale LNG depots use proven, safe technology to liquefy, store, and vaporize LNG. Natural gas is refrigerated to form a liquid at low pressure and is loaded into insulated containers for transportation to depots.
An LNG depot stores LNG locally in insulated tanks, heats LNG to return the liquid to conventional natural gas, and injects natural gas into a distribution system. LNG depots are not bulk storage terminals and hold only small volumes of LNG at any one time.
