Over the past two decades, the helium price has been strongly increasing. The reason is a growing demand and a change in supply chains. Although helium prices were doubling from 2002 to 2012, both…
The History and Status of Helium Production
On Earth, helium is relatively rare (5.2 ppm by volume in the atmosphere) and, therefore, direct extraction from the atmosphere is too expensive. In 1903,…
The estimates of the world’s helium reserves have a large error bar. Since helium is contained in natural gas, the main resources are located in countries with the main resources of natural gas:…
