The only answer that comes to mind is "Airships". Hydrogen, the lightest element, was used in airships, where excess weight was undesirable. However, accidents like the Hindenburg disaster showed that Hydrogen gas was too dangerous(it is extremely flammable) to be used. Since then, Helium has been used instead. Helium is also a very light element, and is completely safe, as it is inert.

What is use of hydrogen in metallurgy?
Hydrogen is used in metallurgy for processes such as hydrogen reduction and hydrogen embrittlement. In hydrogen reduction, hydrogen gas is used to reduce metal ores into pure metals. However, hydrogen embrittlement can occur when hydrogen atoms penetrate the metal structure, causing it to become brittle and susceptible to cracking.
