Helium exists in great quantities in the 4 big planets, which unlike Earth have strong enough gravity to retain it.
Others have mentioned that some helium exists on the Moon, where it comes from the solar wind. The use of the helium 3 from there has been suggested for nuclear fusion, if the fusion of helium 3 became possible (it is much more difficult than the fusion of tritium with deuterium, which is the main approach attempted for now).
However, for fusion relatively small amounts could still be useful. For other uses the amount of lunar helium might not be enough, even when ignoring how expensive it would be to transport it from there.
Recently had to deal with radon in a basement, leading me to a fun side trek of learning about uranium decay (it has been a lot of years since chemistry classes).
When you hear about alpha decay of radioactive materials, that is the matter spitting off a highly ionized helium nucleus, freshly birthed into this world. That He nucleus rapidly steals electrons from matter, which is how it can be dangerous to human cells if ingested.
All of that helium underground is the result of alpha decay, and a single uranium-238 element will birth 8 helium atoms as it transitions through a series of metals and one gas (radon), then finally finding stability as Pb206. U235 will birth 7, becoming Pb207.
Anyways, found that fascinating. It's just happenstance that helium often gets blocked exiting the crust by the same sort of structures that block natural gas from escaping, and they are an odd-couple sharing little in common.
One other fun fact -- radon only has a half life of 3.8 days. Uranium becomes thorium becomes radium, then radon where it has an average 3.8 days to seep out of the Earth and into our basements, where it then becomes radioactive metals that attach to dust, get breathed in (or eaten) and present dangers. In the scale of things, crazy. Chemistry is fascinating.
I really enjoyed this oddlots podcast episode that covered similar points and had a lot of "wat" moments for me, including the US selling off its strategic helium reserves at a loss because politicians labeled it "party baloon reserve", and how long it takes to produce naturally and how hard it is to find, process and transport.
To be fair, the decision to get sell off the strategic helium reserve wasn't a single point in time, it happened little by little, and the original idea came at a time when helium didn't really have a strategic purpose. The last major use for it was military spy balloons sent over western europe to keep tabs on the USSR... Yeah that USSR. They couldn't have anticipated that it would suddenly become ultra-useful for post-2010 semiconductor lithography.
I recently began wondering if a planet's helium supply could be the 'great filter'. As in, if a civilization could stall out due to not having access to enough helium to product the technology to access off-world helium.
This presupposes that there are no alternatives to helium for off world exploration. Would be interesting if warp drives were real but required vast amounts of helium to operate with no substitutions possible.
Pretty much any time there's some kind of problem in the world, someone chimes in to say that maybe not solving this problem is the great filter; and we have exactly the same amount of evidence (none) for all such hypotheses. Why is a shortage of helium more likely to be the great filter than the development of multicellular life, getting absorbed in AI worlds, nuclear war, etc.?
The US used to have a massive Strategic Helium Reserve [1]. Starting in the 1990s, Congress passed a law to sell down the reserve. This flooded the market with cheap Helium (yay, party balloons?) because the mandated pricing just didn't make any sense.
10-20 years ago there was a lot of talk about how this was foolish because it was depleting and squandering an unrenewable resource. But the thinking has shifted on that because it's an inevitable byproduct of natural gas production.
Now natural gas itself is limited but you can still get Helium from alpha decay of radioactive elements. Some elements are particularly strong alpha emitters (eg Polonium-210, Radium-223). They're basiclaly producing Helium constantly.
Helium is a known issue in various industries. The article notes (correctly) that MRI Helium use is decreasing because of the rise of so-called "Helium free" or "Helium light" MRI technology.
But there are short term supply issues. As noted, Qatar produces ~30% of the world's Helium currently. And that can (and has) been disrupted by recent events.
Lithography is a particularly important consumer of Helium for superconducting magnets. That demand is rising with probably no end in sight. Lithography itself is on the cutting edge of technology and engineering so seems harder to replace. I mean, EUV lithography is basically magic.
Ironically exactly now - while we are at or close to peak natural gas extraction - would be the best time to fill up strategic helium reserves worldwide. If every natural gas well was required to capture and store helium for future use we could extend that runway by multiple generations.
But instead of our grandparents and great grandparents general idea of investing in the future of their societies, we’ve decided to stop doing that and add up all the debt possible to pass down to future generations.
I’m not really worried about any potential helium shortage. We are actually really good at extracting it, the problem is purely economics and as soon as prices get to the point where investment is warranted then there will continue to be adequate supplies. The main issue right now is the proper demand increase forecasts do not align with potential investments costs and helium extraction investment does just not make much economic sense given current forecast Helium costs.
If demand keeps growing (as it has been), we've got ~40-60 years of "cheap" reserves left. As helium prices start to increase, you've got price shocks down the supply chain.
There's about 40-70 billion cubic meters of economically recoverable (assuming future technology development + price increases). The complete total upper end of known geological reserves is ~60-100 billion cubic meters - that's about correct in terms of order of magnitude even if we find new deposits.
Current consumption is 180 million cubic meters/year. At a growth of 3%, you've got 80-140 years before we run out. At 5% growth it's 50-90 years.
Saying "I'm not worried about it" is true in the myopically selfish "I personally won't have to care about it". It's conceivable that your children will be dealing with it and definitely grandchildren in a very real existentially meaningful way.
For diving, there has been some experimental use of hydrogen as a partial replacement for helium in breathing gas mixtures. This obviously increases the risk of fires and the physiological effects aren't fully understood. But it might eventually be used in commercial, military, and exploration diving for those cases where we need to send humans really deep and using an atmospheric suit isn't an option. Regular sport divers will probably never breathe hydrogen.
For divers, we really should be focusing on building better underwater drones. Remove the risk to human life entirely. You don't need AI either, just a remote-controlled machine with a cable that goes up to the surface. I know there is some loss in dexterity with current robot arms, but building more dexterous system seems like it's not an impossible task.
Get back to me when drones or robots are being used for dangerous things on land, such as skyscraper construction. Until then, realize it is in fact not easy but extremely difficult and expensive.
Your post is frustrating to read because of the incorrect spelling and grammar; these errors make it hard to take you seriously.

Could be:
"The war in Iran" should be called what it is:
It's 'Trump's War', and nothing else. He's solely to blame. Israel would not have started it on their own.
The kicker is that MAGA voted for the 'no-war' president, and so far, he's started five.
Note that in addition to spelling and grammar, I switched "FIVE" to lower-case italics (which are reverted to regular because the block is italicized), as capitalizing for emphasis is against the HN guidelines.
<10% of natural gas plants recover helium. All of them extract it. The remaining >90% vent it into the atmosphere. This is an engineering / money problem, not a physics problem.
It looks like that by simply reducing use in welding, lifting, and purging gas (all with clear alternatives) and maybe also 'leak detection' and 'other' (not expounded on in the article), they can fill in for the entire Qatari output, and that's without including extra production and recycling which is quiet possible.
>The vast majority of MRI machines used today use superconducting magnets made from niobium-titanium (NbTi), which becomes superconducting at 9.2 degrees above absolute zero. This is well below the boiling point of any other coolant, making liquid helium the only practical option for cooling the magnets.
Well, this is part of it. The other issue is that the superconducting phase diagram has two limits: the transition temperature Tc and the upper critical magnetic field Hc. The magnetic field limit is generally highest at absolute zero and drops steeply with temperature. Even for the superconductors with Tc as high as 120 K the Hc at 20 K will be much less than the Hc at 4 K. So in order to make powerful superconducting magnets you need helium regardless of what superconductor you use, since nothing has broken this pattern.
The long tail economic ramifications that this disruption to the supply chain will have could be potentially decades, in ways that will most certainly be catastrophic, and what's concerning to me is how small of a percentage of the population (at least in the US) is grasping this.
Qatar produce(s/d) about a third of global helium. With the force majeure in place I won't be launching student HABs anytime soon. (Schools don't like hydrogen)
Xenon is very rare too and currently without substitute for certain medical applications, but more interestingly it produces psychoactive effects that could shed light on stuff no other substance apparently can: https://pmc.ncbi.nlm.nih.gov/articles/PMC11203236/
There's two trillion kilograms of it in the atmosphere. People sometimes get confused because it's one of the rarest element in the Earth's crust. But that's because it floats away.
Waaay back in the early 1980s, I read an Asimov essay, “The Vanishing Element”, about the irreplaceable nature of helium and how badly humankind was wasting it. He pointed out that, once released, it just rises through the atmosphere and lost to space. I guess that chicken is coming home to roost.
On June 27, 2024, the Biden Administration announced the final sale and transferring of the U.S. government’s remaining helium reserve to Messer LLC, a subsidiary of a German industrial gas business group with operations in China.
We need the price of helium to skyrocket otherwise it won't be valued at all. If another blimp or balloon is never produced again, I wouldn't blink an eye, it should be reserved for medical and scientific purposes since we can't manufacture it in large quantities.
The EUV lithography dependency is the one that worries me. MRI can reduce consumption 90%+ with zero-boiloff designs. Semiconductor fabs are moving in the opposite direction.. more helium per wafer as feature sizes shrink. That's not a recycling problem, it's a demand growth problem.
