Hydrogen used to be used in airships.
Hydrogen was once used to fill airships. Quite dangerous due to how flammable it is.
Hydrogen was the gas that was once used to filled airships. It is extremely plentiful and easy to produce. However, it is also extremely flammable and caused a few accidents. Helium is now used.
Hydrogen gas is highly flammable and poses a significant safety risk. Therefore, helium gas is commonly used in airships today as it is non-flammable and safer. Additionally, helium has a higher lifting capacity compared to hydrogen, which allows for better control and stability of the airship.
gas is still used in airships to provide lift.
because hydrogen used to be in those airships and since hydrogen is flammable it was very dangerous
There never were hydrogen powered airships. Hydrogen provided lift, not propulsion. Propulsion came from combustion engines using diesel or gasoline.
Using hydrogen in airships is considered dangerous because hydrogen is highly flammable and can lead to explosions if exposed to air. This risk was famously demonstrated by the Hindenburg disaster in 1937, where an airship filled with hydrogen caught fire and crashed. As a result, helium is now the preferred gas for use in airships due to its non-flammable nature.
Today's blimps are not filled with flammable hydrogen gas like Hindenburg was, but normally the non-flammable helium.
Airships typically run on one of two things: helium or hot air. Helium is a non-flammable gas that provides lift for the airship. Hot air is used in hot air balloons to provide lift by heating the air inside the balloon.
Hydrogen isn't used for airships because it is highly flammable. It was one of the causes of the Hindenburg's burning.
Airships were often used to carry freight and passengers. But became unpopular after the advent of jets and other types of aircraft because they are slow. Initially they used fuel which made them highly flammable when accidents occured.
Airships do use gas, to provide lift.
