Geologists have discovered a gigantic new field of underground helium gas, located in Tanzania’s Rift Valley.
Researchers figure there’s about 54 billion cubic feet of helium in just one section of the valley. To put that in context, the Federal Helium Reserve in Texas, which supplies more than 40% of domestic helium needs and contains about 30% of the world’s total helium supply, right now holds about 24.2 billion cubic feet, per Live Science.
The discovery is also important in that it wasn’t an accident. The geologists located the helium based on their theories of where they should find it.
