The discovery of a previously-unknown helium gas field resulted in a
number of stories reminding us how critically low the world's helium
reserves are.
For the first time ever, researchers
have tracked and located a helium gas field. And the discovery,
presented Tuesday during the Goldschmidt geochemistry conference
in Japan, could help allay fears about a global helium shortage, which
could affect such sectors as medicine and manufacturing...
Even though helium is one of the most
abundant elements in the universe, there’s concern that it may be
running dry here on planet Earth.
That was the understanding I had had for years. That's why I understood the U.S. maintains its National Helium Reserve. But the claim of a world shortage of the gas is hogwash, according to this report in Wired:
Most of the world’s helium comes from natural gas, where it can exist in
very small quantities. A good source will be about 3 percent helium,
but more often helium hovers between 0.1 percent and 0.5 percent—nothing
compared to the relatively astronomical 10 percent pocket found in
Tanzania. But worldwide, helium is about a thousand times less lucrative
than gas, so even though removing (inert) helium makes the gas burn
better, companies don’t usually bother to take it out. “Normally, it’s
an afterthought,” says Samuel Burton, assistant field manager at the
Federal Helium Program. “It’s something that they don’t even consider
because the natural gas makes so much more money for them.”
When helium’s price goes up—like it has for most of the past few
years—natural gas companies are incentivized to sell extracted helium on
its own. Countries like Qatar mine so much natural gas that even though
it has relatively little helium, they can crank out a decent percentage
of the world’s demand as an afterthought...
“There is actually so much helium that’s flooding the market that it’s
not in short supply at all,” Burton says. And as for the future, “I’ve
seen a lot of talk about this global shortage of helium—that’s actually
not the case. In the United States, we’ve got at least 20 years of known
supplies that are easily, readily available.”
