According to Gold, perhaps the best evidence for the abiotic origin of oil is the strong association of helium with hydrocarbons. Helium is the second most abundant element in the universe and is formed from the radioactive decay of uranium and thorium.

High-temperature gas reactors (HTGRs): In HTGRs, gasses (typically helium) act as the coolant that is fed directly into the turbine to produce energy. Helium is an inert gas, so it generally won’t chemically react with any material, and exposing helium to neutron radiation won’t make it radioactive. Helium can therefore be heated to higher...

non-reactivity is a rare and exceptional attribute that is useful across the economy. Helium doesn’t even interact with itself in any meaningful way and must be cooled to -269°C (just four degrees above absolute zero)

In 1925, Congress passed a law creating the Federal Helium Reserve (FHR), a storage facility that once held over a billion cubic meters of it. Initially created to ensure supplies for airships, the reserve took on heightened importance after World War II, when helium’s utility in rocketry became apparent. For decades, the federal government’s... See more
