Hydrogen, which has more lift per quantity- is too volatile and explosive- remember the HIndenberg! Helium is only practical lifting gas for modern dirigibiles. There were rumors the Navy synthesized something during World War II for blimp lifting gas but details are sketchy.

Has helium ever been used in blimps?
Yes, helium has been used in blimps as a lifting gas. Helium is less dense than air, which allows it to provide buoyancy and help the blimps stay afloat. However, today, most blimps use a combination of helium for lift and air for control and propulsion.
Do they still use helium in blimps?
Yes, helium is still commonly used in blimps due to its low density and non-flammable properties, making it a safe option for lifting aircraft. Helium provides the necessary buoyancy to keep blimps afloat and is widely used in the aerospace industry for this purpose.
How do blimps work?
Blimps are filled with a lighter-than-air gas like helium, which provides lift to keep them airborne. They are propelled by engines and controlled by adjusting the air pressure inside the envelope and moving the rudder and elevators. Blimps are able to move in different directions by changing the angle of the engines and using wind currents to navigate.
Is lithium in blimps?
Yes, lithium can be used in the form of lithium-ion batteries in blimps for electrical power. These batteries are lightweight and have a high energy density, making them suitable for air transportation applications.
What does helium produce?
Helium is a very light unreactive gas so it can be used in balloons etc.
