Helium
He Is Your Friend
Hongjun Zhou, PhD
Update, 11/2019: From the latest BLM statistics for 2018,
it appears that the Federal Conservation helium has been auctioned off in its fifth and final
auction to comply with the Helium Stewardship Act of 2013. Mandated by the 2013 law,
"the BLM will dispose of all helium related assets when the remaining conservation helium falls below 83.2
million cubic meters or no later than 2021." BLM indicated that "by the end of the decade, international
helium extraction facilities are likely to become the main source of supply for world helium users".
The alternative helium sources will likely include significant import of helium from currently dominating helium plants in Qatar and Algeria,
and a few other countries. One good development is that helium has been listed among 35 critical minerals
(83 FR 23295) by U.S. Department of the Interior.
This may help the domestic efforts in helium production and resource protection.
The good: Closing the Federal Conservation helium operation will significantly boost helium price. It has already
shot up substantially, 2-5 folds, over
the past few years. This will encourage new domestic exploration and conservation.
The bad: How are we going to deal with the
sharp price surge, and manage the cost and supply fluctuation, especially for urgent and critical needs such as for MRI and NMR
instruments?
The ugly: We will be talking to much less reliable helium supply sources and vendors in the international markets.
The helium market will look a lot like the oil market that gyrates around many issues across the globe. This was
illustrated in 2017 when the major helium producer Qatar was put
under Saudi led embargo that significantly disrupted the helium market.
Long-term Helium Supply:
The long-term helium supply is not clear and depends on worldwide plants and reserves. The US was estimated to have
a reserve of > 20,000 million cubic meters, based on the 2006 survey.
Among them, 4,250 million cubic meters are measured reserves with the rest being probable or possible reserves.
Current US and worldwide helium consumption are ~ 40 and 100 million cubic meters per pear, respectively.
Worldwide reserves, exclusive of the US, was estimated to be ~ 31,300 million cubic meters. Based on these figures, we
estimate the current worldwide reserves will sustain the supply for ~300 years at current rates of consumption.
A new USGS helium resource assessment is expected in 2019 and to be published in 2020.
The long-term prospect isn't as bleak as the short-term landscape of helium supply. However, helium is an unrecoverable
natural resources. Unless recycled, any use cuts into the limited reserves and pushes us closer to the days
when it is used up.
The short-term issues with reliable helium supply have to do with specific, time-sensitive, absolute needs for helium,
such as for MRI and NMR instrument cooling. These instruments cannot survive without cooling with helium at all times.
Helium is the air we breathe for these instruments.
In addition to helium recycling, it is
possible that new research and technologies, such as high-temperature superconductivity, alternative cooling methods, alternative
methods of generating large scale high magnetic field, may one day help alleviate the reliance on the use of helium in
such applications.
For recent mass media reports on the helium situation, see:
As one of the inert, noble gases, helium (He) has unique physical properties that
are not replaceable by any other gas available on earth and in the universe.
Helium is the second most abundant element in the universe after hydrogen, at
~23%. Helium 4He atom has two electrons, two protons and two
neutrons. Its naturally occurring, ultra low-abundance isotopic brother is
3He, at only 0.00014%.
Helium has wide-spread applications, far
beyond being light-weight, safe filling for party balloons and blimps. Its
accessibility and reserve on earth plays an essential role in basic and
high-tech research, and is vital in many areas of the economy. However, its
availability has been threatened in the past years by poor policy making and
inaction. More serious helium shortage is on the horizon, 10 to 20 years from
now once the Federal helium reserve
runs out and if new reliable supply cannot
be maintained. Unless serious efforts are made to encourage helium exploration,
extraction and conservation, the reliability of future helium supply will be
jeopardized, threatening basic scientific research and the function and services of
medical diagnostic MRI and NMR instruments, among many other applications.
History of Federal Helium Supply
The Federal Helium Reserve is located near Amarillo, Texas, in a natural geologic gas storage formation,
called the Bush Dome. It consists of a network of storage reservoir, enrichment plant,
and pipeline system. The reserve is managed by
The Bureau of Land Management (BLM) and
supplies ~50% of the US market and ~30% of the world market.
The Federal Helium Program started in 1925 to supply the military with a reliable source
of helium used in buoyant aircraft such as blimps. After the original defence use of the helium
subsidized, the federal helium program remained the only helium supplier in the US in much
expanded applications until 1960. In 1960, due to increased demand for helium, Congress authorized purchase of helium
from private natural gas producers and storage in the Federal Helium Reserve. As the helium demand further increased
worldwide, Congress passed the
Helium Privatization Act (HPA) of 1996 (H.R. 4168) which authorized BLM to
continue to manage the Federal Reserve with the goal of recovering the cost of the federal investment and
the sell-off and disposal of the helium reserve by Jan 2015. This bill was sponsored by Rep. Christopher Cox, and signed into law
by Pres. Clinton.
"Not later than January 1, 2005, the Secretary shall commence offering for sale crude helium from helium
reserves owned by the United States in such amounts as would be necessary to dispose of all such helium reserves in
excess of 600,000,000 cubic feet on a straight-line basis between such date and January 1, 2015."
"(B) On repayment of all amounts referred to in subsection (c), the fund established under this section shall
be terminated and all moneys received under this Act shall be deposited in the general fund of the Treasury."
Because of the dominant market share and ~80% of worldwide helium storage of the Federal Helium Reserve , the mandate to dispose
the helium reserve led to depressed helium price for decades and waste of a precious, irrecoverable resource at
a rapid rate. This short-sightedness offered no incentive for the private sector to extract and store
helium as a byproduct of oil and gas exploration, creating a serious helium shortage problem down the
road.
The BLM was able to recover the cost associated with the Helium Reserve in October, 2013, earlier than expected.
Once the debt was paid off, the Helium Privatization Act (HPA) of 1996 called for cessation of helium sale by the
Federal Helium Reserve, closure of the facility and cutting off funding for managing the helium reserve. The HPA created a serious, imminent helium crisis in 2013 that
led to rigorous lobbying efforts across many fields and industries. These efforts led to the
Responsible Helium Administration and Stewardship Act (H. R. 527)
that passed the U.S. House and Senate, and was signed into law on October 2, 2013.
Helium Shortage Crisis to Come?
Based on 2015 data from
U.S. Geological Survey,
estimated 2014 domestic consumption of helium was 1.2 billion cubic feet and was used for cryogenic applications, 32%; for pressurizing and purging, 18%; for controlled atmospheres, 18%;
for welding cover gas, 13%; leak detection, 4%; breathing mixtures, 2%; and other, 13%.
As of October 2013, the Federal Helium Reserve stored
~10 billion cubic feet of helium. The current legislature calls for the closure of the
reserve for private sector auction when the federal storage drops to ~ 3 billion cubic feet. Without new addition to the domestic helium storage, the Federal Helium Reserve could
only sustain the supply to the US market for ~10 years, assuming a 50% market share of the Federal supply. The
worldwide demand for helium has been increasing steadily. Obviously, new helium supply sources and conservation are absolutely
required to prolong our access to this precious natural resource.

emitted as "alpha" particles from the decay of heavy elements.
- Commercial helium is purified from natural gas in concentrations from
0.1% to 8%.
- Helium is the closest and most abundant thing that could be called
"cosmic ash" because of its low-energy state, but at extreme temperatures
(as in late-stage of the Sun, even helium ash burns and fuses into heavier
element.
- Helium liquefies at 4.2K (or -269.0C).
- Helium undergoes a phase transition into a "superfluid" state below 2.2K where the entire
