About Helium and Its Importance

• Helium is the second-lightest chemical element after hydrogen and is a noble gas with unique properties that make it indispensable for several high-technology applications.
• It has an extremely low boiling point of -269°C and does not participate easily in chemical reactions, making it an ideal coolant and inert medium.

How Helium Is Obtained?

• Helium is a non-renewable resource generated deep in the Earth's crust through the radioactive decay of uranium and thorium atoms, which emit alpha particles that capture electrons to form helium atoms over millions of years.
• Helium migrates into natural gas reservoirs and is extracted alongside natural gas.
• Natural gas is processed to isolate helium only when helium constitutes at least 0.3% by volume of the gas.
• Isolation uses the differing boiling points of helium and other gases.
• Commercial helium is usually at least 99.997% pure.
• Some operators recover helium from LNG plants and from the air, but these quantities are too small to significantly impact global demand.

Global Helium Production

• The world's major helium producers are:

• USA: 43% of the total global supply, the largest producer.
• Qatar: 33% of the total supply, especially serving Asia.
• Russia: With export restrictions requiring the Prime Minister’s sign-off through 2027.
• Canada and Algeria: Smaller but notable producers.

• China, in contrast:

• Produces only about 1.6% of the world's helium.
• Imports more than 80% of its helium requirements.

Uses of Helium

• Cooling Applications

• MRI machines: Cooling superconducting magnets to enable medical imaging.
• Semiconductor fabrication: Removing heat from silicon wafers during chip manufacturing.
• Quantum computers: Cooling devices to near absolute zero temperatures.

• Aerospace and Fuel Systems

• Rocket fuel tanks: Used by organisations like ISRO, NASA, and SpaceX to pressurise fuel tanks.
• Aerospace applications: Critical for space missions and high-altitude operations.

• Manufacturing

• Optical fibre production: Rapidly and uniformly cools molten glass and prevents bubble formation.
• Semiconductor industry: Critical coolant and controlled atmosphere agent.
• Leak detection: Small atomic size makes helium ideal for detecting even microscopic leaks.

• Other Uses

• Balloons and airships: Used as a lifting gas.
• Laboratory research: Various scientific applications.
• Controlled atmospheres: For sensitive manufacturing processes.

News Summary

• Recently, China's Ministry of Commerce and General Administration of Customs temporarily but immediately banned helium exports from the country.
• So far, Beijing had not published detailed information about the scope or reasons for the ban.

Context and Timing

• The export ban comes amid an extended period of strained global helium supply:

• Russia's export restrictions require the Prime Minister to sign off on shipments through 2027.
• Heightened tensions in West Asia, particularly around the Strait of Hormuz, have created supply risks.

• As noted by industry observers, following the escalation of the Iran conflict, "one-third of global helium production is now literally bottled up behind the Strait of Hormuz", a much higher proportion than global oil production affected by the conflict.

The US Factor

• In 2024, the US privatised its Federal Helium Reserve, selling its assets to the Messer Group.
• This eliminated the buffer that had historically cushioned shocks like those from the US-Iran conflict.
• Subsequently, the US House Committee on Oversight and Government Reform launched an investigation into Messer's Chinese interests.
• This has stoked the risk of tit-for-tat trade measures, of which China's latest export ban could be part.

Cost and Supply Chain Challenges

• Helium prices have surged significantly:
  • June 2026 spot price for high-purity helium in Northeast Asia: $150-205 per thousand cubic feet.
  • This is almost double the price in late 2025.
• Complex Supply Chain
  • The helium supply chain is cost-intensive and technically sophisticated.
• Purification and Liquefaction

• Mid- to large-scale facilities require more than $100 million in investment.
• Smaller facilities cost around $10 million.
• Requires corrosion-resistant alloys capable of withstanding ultra-low temperatures.

• Storage

• Underground salt caverns: Reduce leaks significantly, but are rare; new development can cost more than $200 million.
• Compressed gas storage: Typically costs up to $10 million to build.
• Bulk cryogenic liquid storage: Costs between $0.5 million and $20 million, depending on capacity.

• Transportation

• Helium can only be transported in vacuum-jacketed stainless steel vessels.
• These are manufactured by only a few companies worldwide, including several Chinese firms, adding another layer to China's leverage.
• Contractors must ensure delivery before the holding time expires, after which helium will start boiling off into the atmosphere.

Implications of the Ban

• For Global Semiconductor Industry

• Semiconductor fabrication depends heavily on helium as a coolant.
• Any supply disruption could delay chip production globally.
• Countries reliant on Asian semiconductor manufacturing may face indirect impacts.

• For Healthcare

• MRI machines worldwide depend on liquid helium for cooling.
• Supply shortages could disrupt medical imaging services.

• For Aerospace and High-Tech Industries

• Space programmes may face supply challenges.
• Quantum computing research could be affected.
• Advanced manufacturing sectors may need to seek alternatives.

• For Global Trade Dynamics

• Reinforces the trend of weaponizing critical resources in geopolitical disputes.
• Increases pressure on countries to develop strategic reserves.
• Highlights the importance of supply chain diversification.

Implications for India

• Vulnerability Areas

• Semiconductor manufacturing ambitions under the India Semiconductor Mission may face input constraints.
• ISRO's space programmes rely on helium for rocket fuel pressurisation.
• Medical imaging services could face supply disruptions.
• High-tech research and manufacturing sectors may see rising costs.

• Strategic Considerations

• Need to diversify import sources beyond traditional suppliers.
• Consider building strategic reserves of critical materials.
• Invest in domestic helium exploration in natural gas fields.
• Develop alternative technologies where possible.
