The world is facing a critical helium shortage, which threatens much more  than the party-balloon industry.  An odorless and colorless gas, helium (He  on the periodic  table) is the second-most-abundant element in the universe after hydrogen,  but it's not easy to find or store in usable quantities — most of the helium in  the atmosphere escapes into space, and our current helium supplies are largely  extracted from underground natural-gas reserves.
The United States is the global leader in helium production, producing about  75 percent of the world's helium. About half of that is stored outside Amarillo,  Texas, in the country's Federal Helium Reserve, a vast subterranean complex of  storage reservoirs and pipelines that extend to natural-gas fields as far away  as Kansas.
But the looming helium shortage is actually the government's fault, according  to Science  magazine. The U.S. Bureau of Land Management (BLM), which manages the  Federal Helium Reserve, sells off helium at below-market rates, encouraging  waste and discouraging the development of new sources.
"If … companies can buy the federal helium gas at a relatively low price,  there is less incentive to develop it," physicist Moses Chan, a member of the  National Academy of Sciences panel studying the helium reserve, told Marketplace.org.
Helium sales scheduled to endIn 1996, Congress mandated that the federal government get out of the helium  business altogether, so the BLM is selling off its existing supply until it  recoups the costs of producing it. That point will come in October, after which  point the government cannot sell any more helium.
As a result, the United States and much of the industrialized world now faces  an imminent "helium cliff." Legislation that intended to address this problem by  allowing continued helium sales after October was passed by the U.S. House of  Representatives in April, but the Senate has yet to pass its own version of the  bill, according to the Wall  Street Journal.
"We're running out of time," David Isaacs, of the Semiconductor Industry  Association, told the Journal. "We're positioned to get it done, but there's  certainly no guarantee — certainly not in this Congress."
An irreplaceable elementThe Federal Helium Reserve got its start shortly after World War I, when  helium was used to float military reconnaissance aircraft. Since then, helium  has proven to be indispensable in a wide range of industrial and medical  uses.
Magnetic resonance imagery (MRI) relies on helium to regulate the powerful  magnets needed to create MRI scans, which are cooled to minus 452 degrees  Fahrenheit (minus 269 degrees Celsius). Indeed, the fact that helium has the  lowest boiling and melting points of all the chemical elements — liquid helium  is the only liquid that cannot be solidified by lowering its temperature — is  what makes it so irreplaceable in so many industries.
Helium is also essential to the manufacturing of computer chips, optical  fiber and medical lasers. It's often needed for rocket-engine testing, arc  welding, air-to-air missile guidance and other civilian and military uses,  according to the BLM. (Party balloons and parade floats use just a tiny fraction  of the world's helium supply.)
There are some plans in place to address the current helium shortage,  including a new helium plant in Wyoming and increased development overseas. And  assuming that demand for helium remains strong, "new technologies for extracting  and refining helium … would bring new sources of helium to the market,"  according to the BLM.
