The United States has designated helium a critical material, recognising its importance to semiconductor manufacturing and other advanced technological applications.
The US Department of Energy announced the designation on October 23, 2026, under the Energy Act of 2020. The decision places helium on the department's critical materials list, which covers materials considered important to energy technologies and potentially vulnerable to supply-chain disruption.
Editorial Insight
Key Highlights
Important points readers should notice.
The US Department of Energy announced the helium designation on October 23, 2026.
The decision was made under the Energy Act of 2020.
Helium has applications in semiconductor manufacturing and scientific research.
The gas is used in medical imaging and specialised industrial equipment.
International production, processing and transportation contribute to helium supply.
The designation does not guarantee additional production or funding for individual companies.
Helium is widely associated with balloons, but it also has important industrial, medical and scientific applications. Its distinctive physical properties make it useful in semiconductor manufacturing, specialised cooling systems, leak detection and scientific research.
In semiconductor production, helium is used in certain manufacturing and equipment operations. Reliable access to specialised industrial gases is important for chipmakers because these materials support processes that require tightly controlled conditions.
Helium supply is an international industry involving production, purification, storage and transportation. The United States is a significant producer, while Qatar and Russia are also important suppliers. Production capacity and processing infrastructure are relevant factors in determining how much helium can reach industrial users.
Editorial Analysis
Why This Matters
Semiconductors are essential components in computers, smartphones, data centres, vehicles and industrial equipment. Their production depends on specialised materials and controlled manufacturing processes. Helium supports certain semiconductor manufacturing operations and other advanced applications. Its inclusion on the Department of Energy's critical materials list recognises its relevance to these technologies. The designation also highlights the importance of understanding the supply chains behind advanced manufacturing. The availability of industrial materials depends on production, processing infrastructure and transportation, not simply on the existence of natural resources.
The Department of Energy's designation draws attention to helium's importance to advanced manufacturing and the risks associated with relying on specialised materials. It also places helium within the department's framework for identifying materials relevant to energy technologies.
The designation does not, by itself, establish a new production target, guarantee financial assistance to individual companies or ensure an immediate change in market supply. Any practical effects will depend on subsequent policy measures and industry activity.
