TAE Technologies Claims Landmark In Fusion Energy, Sees Commercialization By 2030 (techcrunch.com) 118

Posted by BeauHD from the one-step-closer-to-infinite-energy dept.
TAE Technologies, a 20-year-old fusion energy technology developer, is claiming to have hit a milestone in the development of a new technology for generation power from nuclear fusion. The company said its reactors could be operating at commercial scale by the end of the decade, thanks to its newfound ability to produce stable plasma at temperatures over 50 million degrees (nearly twice as hot as the sun). TechCrunch reports: For TAE Technologies, the achievement serves as a validation of the life's work of Norman Rostoker, one of the company's co-founders who had devoted his life to fusion energy research and died before he could see the company he helped create reach its latest milestone. "This is an incredibly rewarding milestone and an apt tribute to the vision of my late mentor, Norman Rostoker," said TAE's current chief executive officer, Michl Binderbauer, in a statement announcing the company's achievement. "Norman and I wrote a paper in the 1990s theorizing that a certain plasma dominated by highly energetic particles should become increasingly better confined and stable as temperatures increase. We have now been able to demonstrate this plasma behavior with overwhelming evidence. It is a powerful validation of our work over the last three decades, and a very critical milestone for TAE that proves the laws of physics are on our side."

Rostoker's legacy lives on inside TAE through the company's technology platform, called, appropriately, "Norman." In the last 18 months that technology has demonstrated consistent performance, reaching over 50 million degrees in several hundred test cycles. Six years ago, the company had proved that its reactor design could sustain plasma indefinitely -- meaning that once the switch is flipped on a reaction, that fusion reaction can continue indefinitely. Now, the company said, it has achieved the necessary temperatures to make its reactors commercially viable. It's with these milestones behind it that TAE was able to raise an additional $280 million in financing, bringing its total up to $880 million and making it one of the best financed private nuclear fusion endeavors in the world.

        However it's also radioactively hot, and that *does* touch the reactor walls. It'd be interesting to know how they plan to deal with that. One of the common ideas is to use lots of lithium in the walls so they generate hydrogen to feed the reactor, but I've never tried to follow that up. I don't even know whether what is generated is deuterium (or possibly tritium).

          According to TFA, the reactor uses boron+H, not DT.

          B11 + H => 3 He + 18 MeV

          No neutrons are produced.

          There are reasons to be extremely skeptical about their claims. Boron fusion requires much higher temperatures than DT fusion. The difficulty of containing the plasma goes up as the square of the temperature.

          Even DT fusion requires 100M Kelvin. But TAE is half that, right? Well, no. Read the summary carefully with your BS detector turned on. Do you notice that they say 50M "degrees" not "Kelvin"? Then they say it is nearly twice the temperature of the sun. That is only true if the "degrees" are Fahrenheit. So they have actually only achieved about 30M K.

        You are right about size and not being economical for commercial use - it won't be. But tokamaks are the only technology that can so far make a strong technical case that they can reach the point of producing commercial scale power at any cost.

        Calling ITER a "science experiment" is wildly inaccurate. All tokamaks up to the present day have been science experiments. But a new generation are starting operation now that are really engineering testbeds - they are designed not to push plasma parameters further

        • I'm all in favor of science experiments, didn't intend to apply the label as a slander. The point remains (and sounds like you agree) that it isn't designed to tap energy (no lithium / FLiBe etc) and even if so the total cost is probably > 10x what makes sense commercially. I do agree with you tokamaks have potential which is why I singled out CFS as being the most likely commercial success in my opinion.

    The energy released from this reaction is when the unstable boron-11 + proton nucleus splits into 3 alpha particles. They can capture the positively charged alphas and generate electricity directly. No neutrons to deal with, either. In theory anyways.

    The downside is it takes far higher temperatures to puncture the boron nucleus' Column barrier than lighter nuclei. Plasma confinement has got to be crazy to manage at those energies.

    If you read carefully though, what the claim is 50M degree plasma temperatures, no mention of density. If you look at https://en.wikipedia.org/wiki/... [wikipedia.org] The Princeton torus reached 60M degrees in 1978 and 75M degrees around 1980 Of course H-B fusion (which is what the press release describes) requires a lot higher temperature, something like 10X D-T, https://en.wikipedia.org/wiki/... [wikipedia.org] So 600M – 1.2B is the right range, 50M isn’t nearly enough What matters is Lawson criteria: https://en.wikipedia.org/wiki/... [wikipedia.org] Pressure * time at that temperature. They don’t give that. They say a “positive relationshipbetweenplasma confinement and reactor temperature, meaningthatthe company’s compact linear configurationimprovesplasma confinement as temperatures rise”. Which is nice words, but no data at all, or what regime they are in. No info on pressure at all. Note that their next machine will “that will operate well in excess of 100 million degrees Celsius to simulate net energy production from the conventional Deuterium-Tritium (D-T) fuel cycle” *simulate* - that machine is not intended to be net producing power. They give no idea of their target Q. If I go to their article at https://www.nature.com/article... [nature.com] I don’t see any temperature above 1 KeV listed (ion + electron, a somewhat weird measuremn) that is only 12M degrees. (just a quick read, maybe I’m missing something) Their density is around 1e19 Lawson is about 5e20 density * seconds at 50M degrees. But they are only 10M degrees, so their pressure is 5X lower. In terms of pressure they are 250 X lower than breakeven for a 1 second run. But its worse than that, their containment time demonstrated is only milliseconds. So, the existing machine misses Lawson by a factor of about a million which puts them in the same ballpark as Farnsworth fusors There is nothing fundamentally wrong with the field reversed configuration. What is missing here is any data to suggest that it scales better than a Tokomak to get to a production machine. They say they have raised 880M$ but even their next generation machine doesn’t reach break-even for D-T. I see no indication that a break even machine will cost less than ITER. If you look at the papers on their site https://tae.com/research-libra... [tae.com] their magnetic fields are sub kilo-gauss. The ITER field is ~50KG. But ITER has a density around 1e20, at 8KeV (8X the temperature) so about 80X the pressure with 50X the field. It all holds together – the Tri Alpha Energy system gets similar performance per field strength – exactly as expected. It might be 2X better or 2X (or much more) worse, but nothing really exciting going on here.

                  Neutral beams work by first charged ion then using an electric field to accelerate them up to the desired energy. The accelerated particles are then sent though a neutralizer add back the electron to make them neutral charge again. Since they have no charge they aren’t confined to the magnet and can travel into the core. The neutral beams then charge exchange with slower particles so the net effect is positively charged ions with momentum. Then you just point the beams tangentially to drive a current.

          Periodical maintenance is fine, you can just build two fusion reactors and cycle between them. They are about two orders of magnitude less capital-intensive than a fission core.

  • Is that Celcius or Fahrenheit degrees...

    It makes a big difference when you are talking about millions...

  • Fusion physicists measure temperature in eV. 50000000k is ~4keV. By contrast, The ITER pedestal, that’s only just the edge, will have a temperature of 4keV. The core of ITER will have a temperature of 25keV [doi.org]. And it will do that for 30minutes. Now remember DT Fusion requires the lowest energy to overcome the column barrier. TAE’s device only operates for 0.1ms. On top of that, the reaction they are targeting will require an order of magnitude higher temperature than the ITER core that is already [stackexchange.com]

  • "Cold Fusion" could apply to any fusion under one million degrees.

    "Officially" (internet officially), Wikipedia says that "Cold fusion" is at or near room temperature. (Tokamak: 150 million degrees C.) Seriously, though -- consider fusion developments. They all have one million to tens-of-millions of degree plasma, confined with magnetics and/or gravity (unavailable on Earth). Practically, it would be incredible to see practical fusion at less than a million degrees. ne?

    Passing a milestone is a success. Hitting one not so much. I wish them success, but I suspect the text is accurate as it is.
  • Very surprised. I thought the field has gone "cold".

  • But we already got one. A much *much* better one. You might have noticed it... in the sky!!

    So we're still 10 years away from having fusion power? Thanks for the update.

    • No this is new. We've been 20 years away for 60 years. Now we're only 10 years away. The question is... "How many decades will it be until we're only 5 years away?"

      BTW, there was news out of MIT about 3 or 4 years ago that said we were maybe only 5 to 10 years away. Isn't this fun?

      Meanwhile, the cost of the first viable fusion power plant we could probably cover every house in the US with solar panels with a backup battery. But... fusion! It's soooo coool! And it only produces low level radioactive w

My dad ended up losing about $30,000 in the long run, because inevitably all of the "amazing break throughs" didn't pan out. I highly doubt TAE has found anything other than a break through in robbing middle aged men having a mid life c

  • Fusion power is just ten years away - and has been ten years away for the last forty years.

    It's videos like this pointing out the very real math on nuclear fission power that will get people supporting it in the future. These videos point out what has been known for decades but a great many politicians, lobbyists, and ignorant dreamers have been able to hide for far too long. Because of how we communicate today it's going to be impossible to keep nuclear fission from being the dominate form of energy in th

    • Get Nuclear two magnituden cheaper than solar and we'll talk.

      Until then, the future is solar, wind and batteries. Which is a shame, fission has a lot of great complementary properties to solar and wind.

      In a world where form power is the cheapest power source, base power will find itself increasingly stranded.

      Of course, nothing spurs innovation like necessity, so I'm not completely ruling out fission. Just fission as it exists today.

      • Until then, the future is solar, wind and batteries.

        I've been reading claims like that for a very long time, longer than I care to admit. How much longer do I have to wait?

        • It's all a matter of following the money trail.

          Building a new Nuclear plant today would give an LCOE of around $155 per Megawatt hour... IF it runs at 85% capacity. If Tony Seba et al are correct in their latest report, The Great Stranding, Nuclear costs closer to $270 today, and will cost around $2000 in 2030.

          Meanwhile LCOE of Solar is now $49 and LCOE of Wind is $41, and this is projected to gradually sink to around $10-$15 at 2030. So, yes, I do not believe the best-case Nuclear plants of today can reali

            I can also pull numbers out of my ass, put them in a paper, then add "et. al." after my name so I don't have to admit the other contributors have been my cats.

            Why in the hell would nuclear power go from $270 today to $2000 in ten years? Do they expect the price of concrete to go up in that time? If so then why would solar and wind, which require far more concrete for the same generating capacity over nuclear fission, not also see a tenfold increase in costs? That's a bullshit number and can only be expla

              On page 2 you will see that LCOE for new nuclear is around 15 cents, and new wind and solar is 3.5. These are based on in-market pricing.

  • Fusion is one of those pie in the sky things that's perpetually "10 years away".

  • I realize this is a three-day-old necrothread, but...

    TAE has been promising "10 years" for 23 years now. Seriously, they first claimed they would have a commercial reactor within ten years *in 1997*. Every year since then they say the exact same thing in spite of the machine not delivering a single deliverable. p-B11, the "tri-alpha" of their original name "Tri-Alpha Energy" requires 300 eV, and even their pivot to D-T needs at least 100 eV and they can't even do that.
