Is there any way to actually produce helium other than nuclear fusion? I would assume not, but I'm not an expert in this field.

adrianN• 3 months ago

It can form during radioactive decay of uranium and thorium.

wat100003• 3 months ago

And that's where all of our helium actually comes from. Any radioactive decay that emits alpha particles generates helium, since alpha particles are just helium nuclei. When that happens underground, the helium can get trapped. It tends to get trapped in the same places that natural gas gets trapped, so natural gas extraction often encounters helium as well.

Similar to oil and gas (although a completely different mechanism), it takes deep time to accumulate, but can be extracted much, much faster. So although new helium is being generated underground all the time, we can still run out in a practical sense.

nsxwolf• 3 months ago

Atmospheric extraction on Earth would require massive amounts of energy and infrastructure.

Gas giant atmosphere extraction sounds very far future

sixhobbits2• 3 months ago

It's also formed similarly to oil over millions of years underground if I understand correctly so can be a byproduct of natural gas mining.

daemonologist• 3 months ago

It's often found alongside natural gas because the rock structures that can trap methane can also trap other gasses, but the original source is different - thermal decomposition of organic matter for natural gas and radioactive decay, mostly of uranium and thorium, for helium.

I agree that the "accumulation over millions of years" is similar (and similarly a potential problem if we burn through all that accumulation).

Sharlin• 3 months ago

Which is exactly 100% of Earth's helium. Every single helium atom we use is a result of alpha decay, as a very good approximation there isn't any primordial or stellar helium on or in Earth.

nradov10• 3 months ago

Helium is produced naturally by radioactive decay underground. There is no way to artificially produce it in useful quantities.

But we can capture more of it from natural gas wells. Today much helium is just vented off and wasted at wellheads. As the price rises it makes sense to invest in cryogenic helium capture equipment for more wells.

CamperBob22• 3 months ago

If you have something that emits a lot of alpha particles as it decays, you could surround it with a source of electrons, I suppose. The details would have to be left as an exercise, and I doubt you'd get enough helium to be very useful unless you were dealing with large amounts of ridiculously-radioactive substances.

Same with fusion. Due to the implications of E=mc^2, fusion yields a lot of energy and a uselessly-small amount of matter. There don't seem to be many good ways to get a lot of helium besides either waiting millions of years for it to show up naturally, or carefully recycling what we already have.

kergonath5• 3 months ago

Water would be the best for this. The cross-section is good and water can ionise easily. But yeah, you would not get a lot of it.

jmyeet2• 3 months ago

Terrestial helium isn't produced by nuclear fusion. It's produced by nuclear decay. As you may know, you get alpha, beta and gamma radiation from decay. Gamma rays are just energetic photos. You typically need thick lead and/or concrete to shield you from them. Beta radiation is high energy electrons. A thin sheet of steel will shield you from those.

And lastly we have alpha radiation, which is just a Helium nucleus. A sheet of paper will generally block alpha radiation.

Some materials are really strong alpha emitters. A good example is Polonium-210 where almost all of its energy from decay is in the form of alpha radiation. This is why Po-210 is so lethal when ingested, which has been used for that purpose [1].

But this means if you produce a lump of Polonium-210, it's basically radiating Helium. The source of almost all of the Earth's Helium is from uranium and thorium decay.

They are indeed. The average planet busting Gamma Ray Burst is just a Vogon trying to "get the whole family in".

cubefox3• 3 months ago

The reason helium can't be produced chemically (like hydrogen can be produced e.g. from water) is that there are no natural chemical compounds which contain helium. That's because it doesn't form those compounds in the first place, since it's a noble gas.

Not at any temperature nor pressure found on Earth:

These could exist in planets like Neptune or Uranus.

https://en.wikipedia.org/wiki/Helium_compounds

adrian_b2• 3 months ago

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.

llm_nerd2• 3 months ago

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.

That He atom rapidly steals electrons from matter

tfa:

Thanks to its filled outer electron shell, it is inert, and won’t react with other materials

wat100003• 3 months ago

Because it rapidly steals electrons, it becomes inert quickly. Helium you find lying around will be inert. Helium that has just shot out from the radioactive decay of an unstable atom will not be inert.

llm_nerd2• 3 months ago

The particle that is emitted from an alpha decay isn't actually called a He atom (I edited my root comment so this isn't misleading, apologies) -- I was being loose with terminology -- though it has the right number of protons and neutrons. It's called an alpha particle. Once it steals two electrons -- it carries a +2 charge and is extremely successfully at slicing electrons off of other molecules it comes across -- it is then considered the helium that we know and love, and is now stable with the properties we know.

And by stealing those electrons from other molecules it sets off other chemical reactions, which in things like DNA is highly suboptimal. This all generally happens at the birth of the He atom, presuming it isn't in deep space or something with no electrons to cleave from neighbours, and is only an instantaneous state.

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.

https://m.youtube.com/watch?v=bjc6MgUY0BE

parineum2• 3 months ago

Part of the reason there's a shortage is because the US was the main supplier. There was no market incentive for anyone to invest into helium extraction.

It'd be like if the US used it's strategic oil reserve to supply the US with oil at a low price at all times.

A strategic reserve isn't supposed to be used as a supply. The existence of a strategic reserve shouldn't have an effect on the supply of helium except in an emergency. The fact that selling the helium reserve could create a shortage should tell you that it wasn't being used as a reserve but as a supply.

The US was, essentially, artificial subsidizing the price of helium. What's happening now is that people are actually paying the real price of helium.

actionfromafar3• 3 months ago

Exactly right. We may yet find out what happens when someone sells the strategic oil reserve.

marcosdumay2• 3 months ago

The US government decided (maybe correctly, IDK) some years ago that their strategic helium reserves were too high (and thus expensive).

There were several announcements, a lot of discussion, and a long process before they started selling it. It was also a temporary action, with a well known end-date (that TBH, I never looked at). It had a known and constant small pressure over investments, it wasn't something that destabilized a market.

logifail• 3 months ago

The existence of a strategic reserve shouldn't have an effect on the supply of helium except in an emergency.

Is there a widely-accepted definition of "an emergency" in the context of strategic reserves?

[Thinking of the SPR] "Oil/gas prices are currently higher due to geopolitical events, my [potential] voters are getting increasingly unhappy, and there is an election soon" would probably constitute an "an emergency" in the mind of a typical politician and his/her advisors.

Whether eg the SPR was created to (indirectly) help politicians keep their jobs is debatable.

What's happening now is that people are actually paying the real price of helium.

If they're not paying for the negative externalities that come from the methane extraction that comes along with it they really aren't paying the real price at all.

phendrenad2• 3 months ago

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.

actionfromafar3• 3 months ago

That sounds more like a tiny filter. :)

jandrese3• 3 months ago

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.

JuniperMesos• 3 months ago

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.?

jmyeet2• 3 months ago

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.

nradov10• 3 months ago

Shutting down the National Helium Reserve seemed like a good idea at the time. It was originally established when airships were considered essential for national security, largely for maritime patrol. But blimps and dirigibles fell out of favor for most military missions and there wasn't much demand for other uses, so it was politically hard to justify wasting tax dollars to maintain a reserve.

The article briefly touches on insufficient recycling. Though it's not clear for which applications helium recycling is technically/economically feasible and for which it isn't.

phil212• 3 months ago

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.

It is quite depressing to think about.

DoctorOetker5• 3 months ago

This is even true at a genetic level, the human genome is rich in fitness, but with healthcare we are lifting natural selection pressure and feasting on the fitness we inherited as if it can be taken for granted, at the cost of future generations genetic fitness.

Aboutplants• 3 months ago

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.

vlovich1233• 3 months ago

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.

It's very hard if not impossible to do predictions over century timescales. How relevant are 1926 resource problems to today? If you wrote your comment in 1926 you would be talking about rubber, fertilizer, coal, wood or oil, and 4 out of those 5 are mostly solved today.

At those timescales, mining the moon or Jupiter for helium might be realistic, so the limits of earth are no longer upper bounds.

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.

snek_case• 3 months ago

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.

nradov10• 3 months ago

ROVs have already reduced the demand for commercial divers on some types of work. But it's going to take decades (if ever) until they're able to do the full range of human tasks. Some construction work has to be done essentially by feel in near-zero visibility so using an ROV for that would require advanced force feedback mechanisms, maybe imaging sonar and other sensors. Not necessarily impossible, but extraordinarily difficult and extremely expensive with current technology.

For sport and exploration divers, going there yourself is kind of the whole point. I'm not interested in watching a video feed from an underwater drone.

Some technical diving enthusiast planning a 50-stage 20-hour dive to 175 meters, just because the hole is there? Well, you absolutely need some other gas in there, and helium is currently the popular choice.

<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.

jandrese3• 3 months ago

It becomes a larger problem as the world moves away from fossil fuels like natural gas.

I'm not a chemist but are there really no alternatives? Running fusion plants to make helium seems very unlikely to become cost effective, but it would be quite the sci-fi future if we filled party balloons by bombarding hydrogen with free protons.

I guess there aren't any easy molecules to break apart to get helium either since its a noble gas. No hydrolyses type solutions because there aren't any molecules that incorporate helium. I guess radioactive decay, but even that is ultimately limited over long enough timescales.

I actually remember a similar problem from some compound that was mainly formed as a byproduct of some old Canadian nuclear reactor design. As the tech gets phased out, the material is no longer available in significant quantities, with consequences for a projects that need it (like Iter).

Some things can be cheap if they are produced as a byproduct, but very expensive if they have to be obtained directly.

It might be expensive compared to improved Earth mining, but lunar regolite is rich in Helium 3, there would be no need to mine stars.

scythe• 3 months ago

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.

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.

eddythompson803• 3 months ago

That’s not true though. Helium doesn’t just rise through the atmosphere and gets lost to space. A helium balloon rises because it’s less dense than air, so air pushes up on it. It rises until the atmosphere is thin enough and stops there. When helium is not in a balloon, it doesn’t rise because it mixes with air and air doesn’t push on it. The atoms are still smaller and move faster than other gases. Some will go up and eventually gain enough speed to hit escape velocity. According to Maxwell-Boltzmann speed distribution of noble gases, only a small fraction of helium should be escaping the earth atmosphere due to that. The actual amount escaping is larger than predicted, but the exact mechanism isn’t fully agreed upon. Solar winds are thought to be responsible, but that’s just one theory. But the important thing is that helium doesn’t just rise when mixed with oxygen or nitrogen a.k.a “air”

Helium is something that industry has become accustomed to wasting, flagrantly and dismissivly as a "byproduct", by industry that of course means the military and governments exercising there "discretion" in the service of money. And it is the custom of bieng dissmissive that may (likely) be behind the many magnificent piles of rubble that litter the ancient world. A short dip into how the soviets went about capturing certain other nobel gases is educational, when "hard" means something entirely else.
