Why in News?

On 10 July 2026, China temporarily imposed an immediate ban on helium exports, without clearly explaining the reason or scope. The move has heightened global supply concerns amid existing disruptions caused by Russian export restrictions and tensions in West Asia. As helium is indispensable for semiconductors, MRI machines, quantum computing, space technology, and advanced scientific research, it is increasingly being viewed as a strategic resource.

Is China a Major Helium Producer?

China is not a major helium producer. It imports more than 80% of its helium requirements and produces only around 1.6% of the world’s helium.

The world’s major helium producers are:

• United States: around 43% of global supply
• Qatar: around 33% of global demand, especially important for Asia
• Russia
• Canada
• Algeria

China’s export ban is significant because even though China is not a large producer, helium supply chains are already under pressure. The restriction may be aimed at preserving helium for China’s own semiconductor industry, medical sector and advanced technology needs.

What is Helium and How is it Obtained?

• Helium is the second-lightest element after hydrogen. It is a non-renewable resource and is not manufactured commercially.
• It is formed deep inside the Earth’s crust when radioactive decay of uranium and thorium releases alpha particles. These particles capture electrons and become helium atoms.
• Over millions of years, helium migrates into natural gas reservoirs. It is extracted along with natural gas.
• However, natural gas is usually processed for helium only when helium concentration is at least 0.3% by volume. Once extracted, helium is separated using its different boiling point.
• Commercial helium is usually at least 99.997% pure.

Why is Helium Strategically Important?

Helium has two important properties:

• It has an extremely low boiling point of around -269°C.
• It is chemically inert and does not easily react with other elements.

These properties make helium essential for cooling and high-precision technology systems.

Helium is therefore considered a strategic input for future technologies such as:

• Semiconductor manufacturing
• Quantum computing
• Space missions
• Advanced medical equipment
• Scientific research
• Optical fibre production

As countries compete in semiconductors, quantum technologies and space, helium is becoming part of the geopolitics of critical resources.

Major Uses of Helium

Helium is used across advanced technology sectors.

1. Medical Sector

Helium is used to cool the powerful magnets inside MRI machines. Without helium, MRI systems become difficult to operate efficiently.

2. Semiconductor Industry

In semiconductor fabrication, helium is used to cool silicon wafers and maintain controlled manufacturing conditions.

3. Quantum Computing

Some quantum computing devices require ultra-low temperatures. Helium helps cool these systems close to absolute zero.

4. Leak Detection

Helium atoms are extremely small. They can escape through tiny gaps where oxygen or nitrogen cannot pass. This makes helium useful for leak detection in precision engineering.

5. Optical Fibres

Helium is used while drawing optical fibres. It helps cool molten glass rapidly and uniformly and prevents bubble formation.

6. Space Technology

Space agencies such as ISRO, NASA and SpaceX use helium to pressurise rocket fuel tanks.

7. Balloons and Airships

Helium is also used in research balloons, tourism airships and lifting gas applications.

According to the U.S. Geological Survey, major helium demand comes from laboratory uses, controlled atmospheres and semiconductors, lifting gas, MRI scanners, aerospace and leak detection.

Why is Helium Supply Vulnerable?

Helium supply is vulnerable because production is concentrated in a few countries and the supply chain is technically complex.

1. Concentrated Production

The U.S. and Qatar together account for a large share of global helium supply. Any disruption in these regions can affect global availability.

2. Qatar and Strait of Hormuz Risk

Qatar supplies a large share of helium, especially to Asia. Since much of this supply passes through the Strait of Hormuz, tensions in West Asia can disrupt shipments.

3. Russian Restrictions

Russia has imposed restrictions on helium exports, where shipments require high-level approval through 2027.

4. U.S. Federal Helium Reserve Privatisation

The U.S. privatised its Federal Helium Reserve in 2024. Earlier, this reserve helped buffer supply shocks. Its privatisation has reduced the ability of the U.S. to stabilise global supply during crises.

5. China’s Export Ban

China’s ban adds pressure to an already fragile market. It also shows how strategic resources can become tools of trade and geopolitical pressure.

Why is Helium Expensive to Store and Transport?

• Helium is difficult and expensive to store because it liquefies only at -269°C. Maintaining such ultra-low temperatures requires advanced cryogenic technology.

The helium supply chain is expensive at every stage:

• Purification requires advanced industrial facilities.
• Liquefaction needs highly specialised technology.
• Large purification and liquefaction facilities may cost more than $100 million.
• Smaller facilities may cost around $10 million.
• Storage in underground salt caverns can reduce leakage, but such formations are rare and expensive to develop.
• New salt cavern storage can cost more than $200 million.
• Helium can be stored as compressed gas or cryogenic liquid, but both methods require costly infrastructure.
• Transport is also difficult. Helium can only be moved in vacuum-jacketed stainless steel vessels. These vessels are manufactured by only a few companies worldwide, including some in China.
• Another problem is boil-off. If helium containers are not delivered within a fixed holding time, helium begins to boil off and escape into the atmosphere.

Why is Helium Hard to Replace?

Helium is hard to replace because no other gas combines its major properties:

• Extremely low boiling point
• Chemical inertness
• Small atomic size
• Non-flammable nature
• Ability to cool systems near absolute zero

Hydrogen is also light, but it is highly flammable and cannot safely replace helium in many applications. Nitrogen and oxygen are cheaper but do not provide the same ultra-low temperature performance.

This makes helium almost irreplaceable in MRI machines, quantum computing, semiconductor fabrication, leak detection and space missions.

Challenges

• Global helium production is concentrated in a few countries.
• Helium is non-renewable and cannot be manufactured easily.
• Storage and transport infrastructure is expensive.
• West Asia tensions can disrupt Qatar-linked supply.
• Export restrictions by China or Russia can worsen shortages.
• Helium has limited substitutes in critical sectors.

Way Forward

• India should diversify helium import sources.
• Strategic reserves of helium should be considered for critical sectors.
• Recycling and recovery of helium in laboratories and hospitals should be encouraged.
• India should explore helium recovery from domestic natural gas resources where feasible.
• Semiconductor and quantum technology policies should include critical input security.
• International partnerships with reliable suppliers must be strengthened.
• Efficient helium use should be promoted in research, healthcare and industry.

Conclusion

China’s helium export ban shows that future technology competition will not depend only on chips, software or rare earths, but also on specialised resources like helium. Although China is not a major producer, its export restriction matters because the global helium market is already fragile. Helium is essential for MRI machines, semiconductors, quantum computers, optical fibres and space missions, making it a strategic resource. For India, securing helium supply is important for healthcare, space, semiconductor and quantum technology ambitions. Building resilient supply chains, recycling systems and strategic reserves will be crucial for technological self-reliance and Viksit Bharat 2047.
