AskChemit: About the World’s Helium Shortage, Is It a Myth?
The world’s helium shortage is not a myth. It is a real and ongoing issue driven by supply constraints, extraction challenges, and increasing demand for this critical gas. The shortage results from both geological factors and economic dynamics affecting helium’s availability and cost.
Why Helium Is in Short Supply
Helium originates underground as a byproduct of the radioactive decay of heavy elements in the Earth’s crust, primarily accumulating in natural gas deposits. Extraction requires locating natural gas reservoirs with sufficient helium concentration. However, many reserves have low helium or have been reserved for other uses.
Natural gas with high helium content is often not pumped because it is unsuitable for heating purposes. As a result, some helium-rich reserves remain untapped.
| Factor | Impact on Helium Supply |
|---|---|
| Helium origin | Produced by radioactive decay in natural gas |
| Reserves tapped | Only a few known high-helium gas wells worldwide |
| Natural gas usability | Gas too rich in helium isn’t pumped for heating |
| Economic incentive | Helium often too cheap to justify separation |
Economic and Market Dynamics
Despite helium’s production, its extraction depends heavily on economic viability. Helium is relatively inexpensive compared to other gases. Market prices fail to reflect its scarcity fully, leading to underinvestment in extraction and processing facilities.
Prices for helium are inelastic because its applications are essential. Most helium used cools supercooled devices like MRI and NMR machines, so demand remains stable.
As prices rise, more natural gas fields with marginal helium content become economically feasible to exploit, similar to trends in the oil industry. This could slow the shortage but will not eliminate it.
Helium Usage and Conservation
Helium’s key uses include cooling superconducting magnets in medical imaging and scientific instruments, semiconductor manufacturing, and rocket purging. These applications consume substantial helium volumes.
- Many laboratories outside the US use helium reclamation systems to recycle helium, reducing consumption.
- The US remains the dominant global producer but has seen its helium reserves decrease significantly over decades.
- Recycling and reclamation technologies are expensive but necessary to sustain supply, especially as reserves deplete.
Frequent thermal cycling of instruments results in high helium consumption — much is lost when cooling devices to operating temperatures instead of maintaining them.
Current Production and Reserves
The world’s helium supply comes almost exclusively from natural gas. The United States dominates production, providing roughly 80% of the 3.0 billion cubic feet produced annually. Major helium production areas in the US include:
- Hugoton Basin (Texas, Oklahoma, Kansas)
- Green River Basin, Wyoming (LaBarge field)
- Smaller fields in Utah and Colorado
The Federal Helium Reserve (FHR) near Amarillo, Texas, established in the 1950s, stores unrefined helium. It historically supplied much of the U.S. market. However, the reserve is now diminishing after decades of helium extraction and sales.
Global Context and Demand Trends
Worldwide helium-producing gas wells are scarce; fewer than ten active fields contribute significantly. Helium production rates cannot keep pace with increasing global demand, especially for scientific, medical, and technology sectors.
Between 1985 and 1996, U.S. helium consumption doubled, stabilizing recently. New natural gas extraction methods such as hydraulic fracturing have expanded gas availability, but it is unclear if these fields contain helium-rich reserves.
Ethical and Practical Considerations for Use
Helium is a finite, non-renewable resource on a human timescale. Its release into the atmosphere leads to eventual escape into space. This loss raises ethical questions about its use for non-essential purposes like party balloons.
Despite being safer and cheaper, hydrogen is generally avoided for lifting purposes due to safety concerns rooted in historical disasters such as the Hindenburg. This public perception limits its use, contributing to helium demand.
Summary of Key Points
- Helium shortage is real. It stems from limited high-helium reserves and economic factors limiting extraction.
- The US is the largest helium producer, controlling much of the market via natural gas fields and the Federal Helium Reserve.
- Demand, driven by medical and scientific applications, continues to rise, outpacing the slow natural production of helium.
- Conservation and reclamation methods are crucial to sustainably manage helium supplies.
- Helium is a non-renewable, finite resource, with losses to the atmosphere irreversible on practical timelines.
- Hydrogen is a potential alternative lift gas but remains unpopular due to safety concerns.
Is the worldwide helium shortage real or just a myth?
The helium shortage is real. Helium is limited because it comes from natural gas with certain conditions. Prices and extraction challenges make it scarce despite natural production continuing.
Why don’t producers extract helium whenever it’s found in natural gas?
Natural gas with high helium cannot be used for heating. Extractors avoid pumping gas reserves with too much helium. This limits the amount of helium that reaches the market.
How does helium demand compare to its natural production rate?
Helium comes from radioactive decay, a slow process. Demand surpasses natural replenishment, making the supply limited and stretched thin globally.
What role does the United States play in helium production?
The US produces about 80% of the world’s helium. Major fields are in Texas, Oklahoma, Kansas, Wyoming, Utah, and Colorado. The Federal Helium Reserve manages a large part of the supply.
Can helium be recycled or conserved in labs?
Labs in some countries use helium reclamation systems to recycle it. These are costly but needed. The US labs might need to adopt these practices more widely to conserve helium.
