The world is running out of helium 2022

A global helium shortage has doctors worried about one of the natural gas’s most essential, and perhaps unexpected, uses: MRIs.

Strange as it sounds, the lighter-than-air element that gives balloons their buoyancy also powers the vital medical diagnostic machines. An MRI can’t function without some 2,000 liters of ultra-cold liquid helium keeping its magnets cool enough to work. But helium — a nonrenewable element found deep within the Earth’s crust — is running low, leaving hospitals wondering how to plan for a future with a much scarcer supply.

“Helium has become a big concern,” said Mahadevappa Mahesh, professor of radiology at the Johns Hopkins School of Medicine Baltimore. “Especially now with the geopolitical situation.”

Helium has been a volatile commodity for years. This is especially true in the U.S., where a Texas-based federal helium reserve is dwindling as the government tries transferring ownership to private markets.
