The only thing worse than an energy collapse

August 5, 2021

The only thing worse than an energy collapse

We learned recently that one of the last coal power stations in the UK is bidding to become the first commercial nuclear fusion plant on Earth.  The news should be taken with a large pinch of salt… nuclear fusion has been 25 years in the future since before I was born and it will likely still be 25 years in the future the day after I die.  Nevertheless, nuclear fusion reactions have been generated; albeit for just a few seconds and at a massive energy cost.  And the physicists and engineers working on the multinational (International Thermonuclear Experimental Reactor) ITER project in the south of France have something of a spring in their step just now; claiming that:

“ITER will be the first fusion device to produce net energy. ITER will be the first fusion device to maintain fusion for long periods of time. And ITER will be the first fusion device to test the integrated technologies, materials, and physics regimes necessary for the commercial production of fusion-based electricity.”

It is worth noting that ITER is an experiment rather than a working power plant.   And just as well; because even its proponents point to an energy return on investment (EROI) of just 10:1 – about half of the return from a wind turbine.  Even this may be a slight of hand, according to Steven Krivit at New Energy Times:

“Widespread false and exaggerated claims made by leaders in the fusion community have caused many people and institutions to convey the incorrect claims to a wide cross-section of the general public. Below, I’ve listed four of several hundred examples I’ve located. Each of these statements, through no fault of the authors, is fundamentally wrong:

  • New York Times: “ITER will benefit from its larger size and will produce about 10 times more power than it consumes.”

The False Promise of Nuclear Fusion

The False Promise of Nuclear Fusion

CP11j-047-02

There have been some pretty radioactive climate change ideas making the rounds at the COP21 talks in Paris. Team Hansen’s wildly unrealistic notion of switching on 61 new nuclear reactors a year was taking the cake until an even fruitier one reared its familiar head: the nuclear chimera known as ITER.

ITER was originally called the International Thermonuclear Experimental Reactor, with ‘experimental’ being the operative word in that lofty title. Which is perhaps why today they refer to it only by acronym (apparently the word ‘thermonuclear’ also had some rather explosive connotations.) The official website equates ITER with its coincidental Latin meaning, ‘The Way’.

ITER was initiated in 1985 by then presidents Reagan and Gorbachev. The multi-nation project included not only the United States and the already crumbling Soviet Union, but the European Union and Japan. Today there are 35 countries in the partnership.

If it ever gets completed and actually works, ITER will be a fusion reactor known as a Tokomak. Fusion is the physicists’ wet dream, and they’ve been hallucinating about ITER for precisely three decades and Tokomaks and fusion itself for even longer.

ITER itself isn’t even the final step to electricity-producing fusion power plants. Its purpose is in “preparing the way for the fusion power plants of tomorrow.” A tomorrow that is heralded as ten years away, decade after decade.

Wrestling with plasma

Indeed, ITER has been such a perpetually longstanding aspiration that I can delve for information into my father Mike Pentz’s 1994 memoirs without risk of being much out of date. A physicist and founder of Scientists Against Nuclear Arms, here’s how he assessed the challenge of fusion, something he began wrestling with back in 1948.

The energy revolution will not be televised

The energy revolution will not be televised

Three recent news items remind us that energy transitions take time, a lot of time–far too much time to be shrunk down into a television special, a few talking points, or the next big energy idea.

For example, the complex management task of putting together the international fusion research project called the International Thermonuclear Experimental Reactor (ITER) has resulted in estimated final costs that have tripled since the 2006 launch. Fusion could theoretically offer clean and abundant energy almost indefinitely because it uses ubiquitous hydrogen* as fuel and creates helium in the process. (Water you’ll recall is two hydrogen atoms and one oxygen atom and is therefore the most abundant source of hydrogen.)

Despite nine years of effort, ITER has yet to carry out a single experiment; and, the project is not expected to do so for another four years. The idea for such an international project was hatched in 1985 during a summit between U.S. President Ronald Reagan and Mikhail Gorbachev, the leader of what was then still called the Soviet Union. Thirty years later fusion is still receding into the horizon of our energy future.

While there are certainly issues that are managerial rather than merely technical, the technical challenges remain enormous. After decades of experimentation, no laboratory has ever produced more energy from a fusion reaction than it took to create it. One of the most promising tests was performed last year at the National Ignition Facility of the Lawrence Livermore National Laboratory in California. This test produced about 17 kilojoules which was more energy than was used to create the fuel. Problem is, the lasers that initiated the fusion consumed about 2 megajoules or 118 times the amount of energy created by the test.
