LNG is produced by cooling natural gas to -160 C (-265 F), creating a clear colourless, non-toxic, non-corrosive liquid. Because it takes up 600 times less volume than natural gas in its vapour form, LNG is more efficient to store and transport over long distances. Since it must be kept at such cold temperatures, LNG is stored in double-walled, vacuum-insulated tanks.
Natural gas travels by pipeline and then is liquefied before being piped into cryogenic (low-temperature) fuel tanks. Re-gasification facilities return LNG to a gas that can power vehicles or generate electricity.
Union Gas offers a combination distribution, liquefaction and balancing service from Hagar, Ontario. The Hagar facility is located near the TransCanada Highway #17, between North Bay and Sudbury. The location expects to produce, for sale, between 500 and 700 bulk tank truckloads of LNG a year.
