China Outspends the US on Fusion in the Race for Energy's Holy Grail (wsj.com) 75

Posted by msmash from the intensifying-race dept.
A high-tech race is under way between the U.S. and China as both countries chase an elusive energy source: fusion. From a report: China is outspending the U.S., completing a massive fusion technology campus and launching a national fusion consortium that includes some of its largest industrial companies. Crews in China work in three shifts, essentially around the clock, to complete fusion projects. And the Asian superpower has 10 times as many Ph.D.s in fusion science and engineering as the U.S. The result is an increasing worry among American officials and scientists that an early U.S. lead is slipping away.

JP Allain, who heads the Energy Department's Office of Fusion Energy Sciences, said China is spending around $1.5 billion a year on fusion, nearly twice the U.S. government's fusion budget. What's more, China appears to be following a program similar to the road map that hundreds of U.S. fusion scientists and engineers first published in 2020 in hopes of making commercial fusion energy. Scientists familiar with China's fusion facilities said that if the country continues its current pace of spending and development, it will surpass the U.S. and Europe's magnetic fusion capabilities in three or four years.

      We already know how to.

      After decades, Wendelstein 7X is already working as it should (but it's only a research reactor, not a commercial one). Take-away lesson was that fusion is "here", but the first 1-2 commercial iterations will be more expensive, until.they figure out all the small.optimizations - as it's the case with every research-gone-commercial project.

      They even put a price tag on the first one: $20 bn. Yes, $20 bn and then you have a working fusion reactor that can provide energy to a city.

      Subsequent iterations will be significantly cheaper.

      And 3 months ago a research group published work that just made commercial, industrial-grade superconducting magnets 20x cheaper. (That was the most critical and "unoptimized" component of current fusiom tech.)

      So, Chinese do it right. At this point it's not a gamble anymore, it's business. You pay the (increasingly smaller by every iteration) price, you get the product.

      This is a massive underselling of the problem. While it is a relatively trivial matter to produce enough solar to collect enough energy there is no economically viable means of storing and distributing it at required scales with current technology.

          Not in mature markets it isn't. As we've seen in markets with significant mix of solar this is self-limiting. Adding more solar leads to market saturation diminishing value in the same way oversupply in any market reduces the value of commodities supplied. This necessarily limits further investment as there is no longer an economic justification for capital expenditures.

            Storage is actually quite trivial as technology (I could write several paragraphs consisting of nothing but the existing methods), it's just a matter of how long it takes to go from near-zero infrastructure to worldwide.

              Nobody is talking about "retreating". Self-limiting does not mean retreating. It is already happening with the rooftop market drying up in the US. Nobody is going to invest in new capacity if it doesn't yield sufficient value to pay for itself. They will take their dollars and go invest in something else.

              Cost of solar panels by themselves is today almost irrelevant in terms of overall capital and maintenance costs.

While it's true that the "empire is striking back" in some areas with bullshit fees and HOA restrictions, that just shows what a threat it's become.

          The bigger issue when it comes to funding is that we have a climate crisis and need solutions now, not decades down the line.

            And yes, waste management is an "afterthought" in most cases, because it is a problem that is really easy to push off. The materials are actually very dense, so it doesn't take that much space to store them, the engineering for doing it is pretty straight forward, and we have all the technology already.

        Does Fusion produce radioactive nuclear waste the same way fission does?

        Nuclear fission power plants have the disadvantage of generating unstable nuclei; some of these are radioactive for millions of years. Fusion on the other hand does not create any long-lived radioactive nuclear waste.

      • The plan is either to have neutron free fusion by switching to different fuels or capture most neutrons with lithium to breed tritium.
        Of course parts will always eat neutrons and get radioactive. But that won't be unmanageable as it is not highly radioactive like fission products.
        In the long run we need neutron free fusion - or you have have to throw away most of the reactor every ten years.

      • I hope it's always fifty years off, because we still haven't figured out what to do with the radioactive waste products.

        But we have figured out what to do with the radioactive waste products. In the case of China they dump the waste into the sea and blame it on the Japanese. For the rest of the world the waste is contained in concrete casks for display in museums. After being allowed to decay for 300 years the contents of the casks are considered safe for reprocessing into new fuel. After reprocessing there will be products useful for fuel an others considered useful for medical and industrial processes.
