Hydrogen gas has been largely replaced with helium gas in applications like ballooning and airships primarily due to safety concerns. Hydrogen is highly flammable and poses explosion risks, while helium is non-flammable and safer to use. Additionally, helium is less reactive, making it a more stable choice for various applications. Although helium is more expensive, its safety advantages outweigh the cost for many uses.
