Helium is inert. Will not burn like hydrogen does so well.
Hydrogen is highly flammable, posing a significant safety risk for airships. This was highlighted by disasters such as the Hindenburg crash in 1937. As a result, the use of hydrogen in airships was phased out in favor of safer alternatives like helium.
Helium has a stable electron configuration with a full outer shell, making it non-reactive and safe to use in airships. In contrast, hydrogen has a single electron in its outer shell, making it highly reactive and prone to combustion in the presence of oxygen, posing a safety risk in airships.
There never were hydrogen powered airships. Hydrogen provided lift, not propulsion. Propulsion came from combustion engines using diesel or gasoline.
Hydrogen combines with oxygen with explosive force in the presence of a spark. Helium is an inert gas that will not burn or explode, so is much safer to use in balloons and air ships instead of hydrogen.The Hindenburg incident is a good example of why not to use hydrogen in a balloon. In the related links box below I posted an article on it.Helium is more chemically stable than hydrogen and will not burn.study island cheaters.Hydrogen burns very easily and helium doesn't. Because hydrogen is extremely flammable or explosive, it is extremely dangerous to use it in this application. That's why we see helium, and inert gas, used in these lighter than air craft.Because hydrogen is flamable and helium isnt. The airships need a fuel that isnt flamable because if there is a fire, the fuel with explode and cause a huge explosion that will put many peoples safety at risk. Therefore, the clearly safer option is heliumHydrogen is highly combustible and is more reactive compared to helium, as helium is an inert gas.I prefer hydrogen, it is cheaper and reactive. However Helium is often used because it is inert and doesn't burn.
Modern spacecraft use helium instead of hydrogen because helium is not as flammable as hydrogen, making it a safer choice for various applications. Additionally, helium is chemically inert, so it does not react with other materials used in spacecraft systems, reducing the risk of explosions or fires. Helium also offers good lifting capabilities and is readily available.
Modern airships use Helium for lift which is non-combustible whereas in the past airships such as the Hindenburg used Hydrogen for lift which is highly combustible. In addition, modern airships take advantage of new alloys and polymers which give them a much stronger airframe.
Generally speaking, helium is safer, as it is an inert gas, but Hydrogen is cheaper to make and is lighter.
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.
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.

Helium is inert whereas hydrogen is flammable and under some conditions explosive

Helium is much less dense than air, meaning it can provide lift. The only gas lighter than helium is hydrogen, which is too dangerous to use for such a purpose because it is extremely flammable. Helium, on the other hand is completely nonflammable. Aside from hydrogen no other gas is anywhere near as light as helium.
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.
Yes. Hydrogen was the material originally used to produce lift in airships. Hydrogen (H2, also called dihydrogen) is cheap and easy to produce, as it can be created through the electrolysis of water. Hydrogen is also the lightest element in existence, and since airships attained lift using lighter-than-air materials, this was a valued trait. However, hydrogen is highly flammable in the presence of oxygen; even explosive! So a lot of effort went in to preventing ignition of the hydrogen. Passengers were searched before boarding an airship to ensure sure they had no matches or lighters in their possession. Smoking was prohibited while aboard the ship, except in one specially designed compartment, which contained one lighter. Hydrogen was the main source of lift for the majority of airships in Europe from the late nineteenth century to the mid twentieth century. However, in the United States of America, a natural source of the lighter-than-air gas helium was discovered. Though heavier than hydrogen, helium was favored for safety purposes, as unlike hydrogen, helium is nonflammable. However, helium was far rarer and more valuable than hydrogen, as it could not be as easily produced. As the United States of America had a monopoly on helium at the time, it had to be imported by the European countries which used airships. Most notably by Germany, with its famous Zeppelins. But shortly after Hitler became the Fuhrer of Germany, America began to enforce a trade embargo of helium exports against Germany. Because of this, Germany could no longer use helium in their airships, and were forced to resort back to hydrogen. During this time, the Hindenburg, the largest airship ever constructed, was the pride of Germany. The Hindenburg was constructed to be flown using helium, believing the ban on helium exports would be lifted; but it was not. As such, the Hindenburg was forced to fly using hydrogen. As it was landing in New Jersey, the hydrogen ignited, and the ship crashed. It became one of the most famous airship disasters in history. The use of airships did not directly stop after the Hindenburg, however. But the majority of newly constructed airships were helium lifted. The majority of these helium airships were constructed in the United States of America, and were known as blimps. Blimps are still used to this day; however, they are smaller than their Zeppelin counterparts, and seldom used as a means of transportation. To conclude the answer to your question; hydrogen was used in airships, but due to the dangers, it is almost never used now.
An airship uses helium which weighs less than air, and it cancels out the weight of the airship. Hydrogen weighs even less than helium, but it is combustible, so helium is preferred for use in airships.
