The gas used in airships is almost always helium.
In the early 20th century, some airships were built using hydrogen, which provided a slightly higher lifting capacity, but was both corrosive and flammable. Only a few locations had access to helium and international sales were at times restricted. It became much more widely available by the 1950s. But by then the era of very large airships had come to an end.

Helium has a low density and will provide good lift. Put a bunch of helium in a sack and it will displace enough air to provide sufficient buoyancy for the sack to rise up and lift a considerable amount of stuff with it. Works well. Also, helium is an inert gas, and because it doesn't react chemically with anything else, it doesn't present much risk when it is used. The Goodyear folks have been building airships and using helium to fill them since the mid-1920's, and their big blimps are still cruising American skies. Chances are good that you've seen one. The helium was recovered as a byproduct from the petroleum industry's natural gas well operations where it is mixed in with the underground natural gas in recoverable amounts.
There is also another very light gas used in airships. Hydrogen. When the Germans were building and flying their huge lighter-than-air ships in the 1930's, their choice of gas was hydrogen. Hydrogen is considerably less dense than air, too. And hydrogen is very easy to come by. Easier than helium. A lot easier. Just take plain old water, apply a little electricity and it will break into its constituent atoms - hydrogen and oxygen. Need hydrogen? Make all you want. Easy. Oh, but there's a catch. Hydrogen is highly flammable. One spark in the presence of air (oxygen) and the bag that you filled with the hydrogen will go up in a big ball of fire. If you haven't seen the short film clip of the Hindenburg disaster, the big German airship that met with such a catastrophic end on May 6, 1937, check it out. Hydrogen use in airships has disappeared. It's way too dangerous. It's all about helium now.
Helium is a safe gas to use in airships.
What else can I help you with?
Do airships use gas?
Airships do use gas, to provide lift.
What gas helps airships float?
the gas that helps airships is i hate you wikianswers.com
Why is gas no longer used for airships?
gas is still used in airships to provide lift.
What flammable gas used to be used in airships?
Hydrogen used to be used in airships.
What were the early uses of hydrogen?
Hydrogen was used for balloons and airships(zeplins) because it is the lightest gas, but highly flammable, so now we use helium because it is very safe. Hope this helped xxx
Do you still use hydrogen powered airships?
There never were hydrogen powered airships. Hydrogen provided lift, not propulsion. Propulsion came from combustion engines using diesel or gasoline.
Is helium non-combustible gas?
Yes, helium is a non-combustible gas. It is chemically inert, meaning it does not easily react with other substances to ignite or burn. This property makes helium safe for use in various applications where combustion is a concern, such as in balloons or airships.
What gas do you use in airships today?
In their early history, buoyant airships (zepellins, blimps) were filled with hydrogen, a highly flammable gas. Since the Hindenburg disaster, hydrogen has been supplanted by helium, a much more expensive material, but one that is inert and hence much safer.
Was was the name of gas filled airships developed by the Germans?
Zeppelins.
How do airships move?
Airships move primarily through the use of buoyancy and propulsion. They are filled with a lighter-than-air gas, such as helium or hydrogen, which allows them to rise. For horizontal movement, airships are equipped with engines and propellers that generate thrust, enabling them to steer and navigate through the air. The combination of buoyancy for altitude control and propulsion for forward movement allows airships to travel efficiently.
Which floatation gas has been replaced by safer helium in airships?
The gas that helium replaced was Hydrogen
What accident led to change hydrogen gas in airships?
The Hindenburg disaster
