Llewellyn King: America's vulnerability to China's not-so-secret weapon -- rare earths

Rare earths are used in the manufacturing of wind turbines.

In October 1973, the world shuddered when the Arab members of the Organization of Petroleum Exporting Countries imposed an oil embargo on the United States and other nations that provided military aid to Israel in the Yom Kippur War. At the same time, they ramped up prices.

The United States realized it was dependent on imported oil — and much of that came from the Middle East, with Saudi Arabia the big swing producer. It shook the nation. How had a few foreign powers put a noose around the neck of the world’s largest economy?

Well, it could happen again and very soon. The commodity that could bring us to our knees isn’t oil, but rather a group of elements known as rare earths, falling between 21 and 71 on the periodic table. This time, just one country is holding the noose: China.

China controls the world’s production and distribution of rare earths. It produces more than 92 percent of them and holds the world in its hand when it comes to the future of almost anything in high technology.

Rare earths are great multipliers and the heaviest are the most valuable. They go into many of the things we take for granted, from the small engines in automobiles to the wind turbines that are revolutionizing the production of electricity. For example, rare earths increase a conventional magnet’s power by at least fivefold. They are the new oil.

Rare earths are also in cell phones and computers. Fighter jets and smart weapons, like cruise missiles, rely on them. In national defense, there is no substitute and no other supply source available.

Like so much else, the use of rare earths as an enhancer was a U.S. discovery: General Motors, in fact. In 1982, General Motors research scientist John Croat created the world’s strongest permanent magnet using rare earths. He formed a company, called Magnequench. In 1992, the company and Croat’s patents were sold to a Chinese company.

From that time on it became national policy for China to be not just the supplier of rare earths, but to control the whole supply chain. For example, it didn’t just want to supply the rare earths for wind turbines; it insisted that major suppliers, such as Siemens, move some of their manufacturing to China. Soon Chinese companies, fortified with international expertise, went into wind turbine manufacture themselves.

“Now China is the major manufacturer of wind turbines,” says Jim Kennedy, a St. Louis-based consultant who is devoted to raising the alarm over rare earths vulnerability. A new and important book, Sellout, by Victoria Bruce, details how the world handed control of its technological future to China and Kennedy’s struggle to alert the United States.

At present, the rare earths threat from China is serious but not critical. If President Trump — apparently encouraged by his trade adviser Peter Navarro, and his policy adviser Steve Bannon — is contemplating a trade war with China, rare earths are China’s most potent weapon.

A trade war moves the rare earths threat from existential to immediate.

In a strange regulatory twist the United States, and most of the world, won’t be able to open rare-earths mines without legislation and an international treaty modification. Rare earths are often found in conjunction with thorium, a mildly radioactive metal, which occurs in nature and doesn’t represent any kind of threat.

However, it’s a large regulatory problem. The Nuclear Regulatory Commission and the International Atomic Energy Agency have defined thorium as a nuclear “source material” that requires special disposition. Until these classifications, thorium was disposed of along with other mine tailings. Now it has to be separated and collected. Essentially until a new regime for thorium is found, including thorium-powered reactors, the mining of rare earths will be uneconomic in the United States and other nuclear non-proliferation treaty countries.

Congress needs to look into this urgently, ideally before Trump’s trade war gets going, according to several sources familiar with the crisis. A thorium reactor was developed in the 1960s at the Oak Ridge National Laboratory, in Tennessee. While it’s regarded by many nuclear scientists as a superior technology, only Canada and China are pursuing it at present.

Meanwhile, future disruptions from China won’t necessarily be in the markets. It could be in the obscure but vital commodities known as rare earths: China’s not quite secret weapon.

Llewellyn King: An answer to Chinese domination of rare earths

  Rare earth elements – there are 17 of them – have the world’s manufacturing by the throat. They are, as John Kutsch, director of the Thorium Energy Alliance, says, “the great multipliers.” They make metals stronger, generators more efficient, cell phones smaller, television sets sharper, and laptops lighter. They are, in their way, as important to modern manufacturing as energy.

At one time, the United States was a major supplier of rare earths -- with supplemental supplies coming from countries around the world, including Australia and Brazil. Today, 90 percent of the rare earths the world uses come from China.

The use of rare earths is as important in lasers and jet engines as it is in aiming cruise missiles, which means the United States, and the rest of the world, has a huge vulnerability: China controls the supply of new war-fighting material. All U.S. defense manufacturers – including giants Boeing, General Electric and Lockheed Martin -- are dependent on China. Now China is demanding that U.S. companies do more of their manufacturing there: China wants to control the whole chain.

Yet, as the rare earth elements industry is quick to assert, rare earths are not rare; they are scattered generously throughout the world. So why China’s dominance?

China has three main advantages. The first is that in 1984, leader Deng Xiaoping adopted a major initiative, the so-called 863 Program, to move China from being a simple supplier of raw materials and products, enhanced by cheap labor, to being an industrial powerhouse and scientific giant. Rare earths were one of the areas singled out in the program.

The second advantage is that the Chinese ignored – and, to a large extent, still do -- the environmental costs of rare earths' extraction. The environmental damage is described by those who have been to one of two major Chinese sites, which have a combined population of 17 million, as catastrophic, with mountains bathed in acid to remove the sought-after rare earths, resulting in lakes of acid.

China's third advantage is a natural one: It has a lot of ionic clay, which contains rare earths without the associated uranium and thorium.

About the time China was ramping up its plans to dominate the world rare earths market, the United States, in conjunction with the International Atomic Energy Agency, based  in Vienna, began to regulate so-called source materials. These are materials which, at least in theory, could be fashioned into weapons. In reality, those associated with rare earths are not in sufficient quantity to interest potential proliferators.

But the regulations are there. Many in the rare earths elements industry believe that it was these regulations -- particularly as affecting thorium -- that crippled production around the world and essentially closed down the U.S. industry, just as demand was escalating.

There is a commercial market for uranium. While hardly any thorium is used nowadays, it was once used in some scientific instruments and mantles for lighting. Thorium is akin to uranium in atomic weight, and it is a fertile nuclear material. That means that it can be used in a nuclear reactor, but it has to be ignited by a fissile material, such as enriched uranium or plutonium.

Thorium is radioactive, but mildly so. It is an alpha emitter, which means it can be shielded with tissue paper and will not penetrate the skin. However, it has a half-life of 1.5 billion years.

The answer, according to James Kennedy, a science consultant and rare earths expert, is to develop a reactor using thorium instead of uranium. This reactor, called a molten salt reactor, is inherently safe, say its passionate advocates, and would be a better all-around nuclear future. The technology was pioneered by one of the giants of the early nuclear age, Alvin Weinberg, at the Oak Ridge National Laboratory, but abandoned under pressure from enthusiasts for light water reactors, the kind we have today.

The Thorium Energy Alliance believes that the United States and other countries should develop a cooperative to source rare earths from the existing mining of phosphates and metals and store the thorium until it becomes a useful fuel. A bill to do this is making its way through Congress, but its chances are slim. Short of putting a value on thorium and isolating it, the chances of a rare earths elements industry reawakening in the United States, or elsewhere, is rare.
