Pure-play helium, also known as primary helium or green helium is helium that is extracted from the earth as the main product. Since the early 20th century, most of the world's helium supply has been extracted from natural gas as part of the nitrogen rejection process. The preference for primary helium is driven by the planned reduction in use ...
Improved efficiency of use, and the avoidance of waste, can be expected to stretch helium supplies. Further natural gas sourced helium cannot necessarily be expected to continue if natural gas is to be phased out on a journey to Net-Zero. There is a need for those helium using sectors that can substitute away from helium to do so. [24]
All commercial production of helium comes from natural gas.There are two basic types of commercial helium deposits: natural gas produced primarily for the hydrocarbon content, typically containing less than 3 percent helium; and gas with little or no hydrocarbons, produced solely for the helium, which typically makes up between 5 and 10 percent of the gas.
Helium also has a very low boiling point (-268.9°C or -452°F), allowing it to remain a gas even in super-cold environments, an important feature because many rocket fuels are stored in that ...
A buffer gas adds pressure to a system and controls the speed of combustion with any oxygen present. Any inert gas such as helium, neon, or argon will serve as a buffer gas. A buffer gas usually consists of atomically inert gases such as helium, [1] [2] argon, or nitrogen. [3] Krypton, neon, and xenon are also used, primarily for lighting.
A major advantage is that this gas is noncombustible. But the use of helium has some disadvantages, too: The diffusion issue shared with hydrogen (though, as helium's molecular radius (138 pm) is smaller, it diffuses through more materials than hydrogen [4]). Helium is expensive. Although abundant in the universe, helium is very scarce on Earth.

Some authorities believe this system was a disc generator with a helium and argon carrier gas and potassium ionization seed. In 1994, there were detailed plans for FUJI-2, a 5 MWe continuous closed-cycle facility, powered by natural gas, to be built using the experience of FUJI-1. The basic MHD design was to be a system with inert gases using a ...
