Cryogenics

Natural gas (the same gas many people use in their homes to prepare food), becomes liquid at a temperature of -162 degrees Celsius. Its volume is reduced by a factor of 600  compared to the gas in its liquefied state, which makes its transportation much more efficient. Aboard The Argonon, the liquefied gas (LNG) is stored on deck in a cryogenic tank: a double-walled tank with a vacuum between those walls. Because of this vacuum the outer and inner wall are seperate, so as not to allow warmth to spread. To inject LNG into the engine, LNG needs to be converted back into its original gaseous form. To accomplish this we use heated up cooling water of the engine on The Argonon.
