Rare, Unique, Valuable

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.

 

Helium-3

Vs.

Helium-4
Scarcity

Extremely rare at Earth’s surface, formed mainly from tritium decay or released from deep-mantle sources. Trace concentrations only; more abundant on the Moon’s surface.

More abundant in nature, makes up >99.999 % of all helium in Earth’s atmosphere and is produced continually from radiogenic decay of U and Th. It is found in trace amounts in many natural gas fields.
Pricing

~US $15 000 – $19 000 per gram (≈ $2 000–$2 500 per liter gas @ STP). One of the world’s most valuable natural gases, driven by scarcity and strategic importance.

~US $60 per kg (liquid). Commonly used industrially for cooling, lifting, and welding applications.
Demand

High-tech enabler gas essential in quantum computing, fusion energy, cryogenics, neutron detection, and advanced medical imaging.

Industrial backbone gas used for MRI systems, semiconductors, leak detection, fiber optics, and aerospace.
