Does LNG smell?
No. LNG is odorless, non-toxic and non-corrosive. The natural gas used in other applications such as domestic gas, is odorized for the express purpose of detecting leaks. While LNG cannot be odorized as a cryogenic liquid, the accidental release of the vapor can either be detected by electronic methane detectors or it can be odorized like natural gas if it is supplied to systems that will use the gas phase like CNG vehicle systems.
