History of Cryogenic Fuels
The history of cryogenic fuels stretches back to the 19th century when scientists first started experimenting with the use of liquid gases for cooling and other applications. Since then, cryogenic fuels have become an important part of many industries and are widely used in a variety of applications, from space exploration to medical research.
Cryogenic fuels, also known as cryogens, refer to a group of substances that are capable of being liquefied at very low temperatures, typically below -150°C.
