About ³He
What is it?
Helium-3 is a scarce, non-radioactive isotope of helium with extraordinary quantum properties. It enables technologies that operate at the edge of physics, from superconductivity and cryogenics to quantum computing and fusion energy, where ultra-cold, stable environments are essential.
Where is it found?
Helium-3 is found deep within Earth’s mantle (leftover from when Earth formed) and is produced at Earth’s surface through the decay of tritium. On Earth it exists only in trace amounts, making discoveries like Pulsar’s significant. Beyond our planet, the Moon’s surface holds vast reserves, driving interest in future lunar mining missions.
What is it worth?
Helium-3 is one of the most valuable gases on Earth. Traded at around US $15 000–$19 000 per gram (≈ $2 000 – $2 500 per liter of gas at STP), its scarcity and strategic applications command prices far exceeding gold or platinum.
How is it used?
Helium-3 has several high-value scientific and medical uses. It enables ultra-low-temperature cooling essential for quantum computing, detects illicit nuclear materials at ports and borders, and supports specialised lung imaging used to diagnose respiratory conditions. It is also being researched as a potential fuel for future fusion energy, which could generate power with significantly less radioactive waste.
