Coal Industry Could be in store for a ‘rare earth’ reboot

Written by John Siciliano, Energy and Environment Reporter, Washington Examiner on . Posted in Media, News

The coal industry’s future may have much more to do with building smartphones, wind turbines and missile defense radar than billowing smoke stacks and environmental finger pointing, say federal coal advisers and experts.

The direction of the industry is aimed at harvesting what are known as “rare earth elements,” for which the U.S. industry depends on China.

The 19 elements are key ingredients in building complex electronics used in smartphones, jets, defense applications, advanced wind turbines and renewable energy, not to mention light-emitting diodes, or LEDs.

The bottom line is that the U.S. needs to diversify its supply of the minerals, and the coal industry is the nation’s best ticket to do that.

“To the extent that the administration is interested in and regards national defense as a strong national priority, I would think that they are very interested in securing a secure supply of rare earth elements that don’t rely on China,” said Paul Ziemkiewicz, West Virginia University’s water research director, who is at the forefront of transitioning the coal industry into a source of raw materials and mineral security.

The U.S. uses about 15,000 tons of rare earth elements every year, with about 800 tons of that going to the defense industry, he said. “And that’s for high-performance radars, sensors, magnets, some very specialized applications that [should] rely on a strategic reserve in this country.”

In 2016 alone, the U.S. imported more than one-half of its supply of 50 types of minerals, eight of which are identified as rare earth elements critical to the economy, according to the U.S. Geological Survey. Of those 50 minerals, the U.S. was 100 percent dependent on imports for 20 of them, including all eight critical and rare earth minerals. New data released this year showed that rare earth mining was nonexistent in the U.S. in 2016, while China continued to expand its market and dominate the global supply chain.

Appalachian coal mine waste could provide key ingredients for clean energy

Researchers at state universities in the Southeast are closing in on whether one of the region’s biggest liabilities – coal mine waste – might become a valuable asset by supplying rare earth elements needed for clean energy and other applications.

The answer lies in whether the University of Kentucky, Virginia Tech and West Virginia University, working with federal energy laboratories, a few coal companies and large manufacturers, can identify ways and locations to economically extract and process rare earth elements from the waste streams left over from mining coal throughout Appalachia and Western Kentucky.

“We’re working with members of the coal industry and state agencies that are engaged in treating AMD (acid mine drainage) solids to sample their waste streams, said Paul Ziemkiewicz, the lead researcher who heads the West Virginia University’s (WVU) research with colleagues Xingbo Liu and Aaron Noble at its Water Research Institute in Morgantown.

The collaborative effort faces its first key milestone this summer when it completes the first of two phases under $7 million of federal funding, said Roe-Hoan Yoon, the lead researcher at Virginia Tech in Blacksburg. The first $1 million is to produce a report summarizing their research findings to date.

Phase two, budgeted at $6 million, is to design a mobile pilot processing plant that could move among several sites, may be at risk if Congress does not pass a budget for the current or next fiscal year, which begins October 1. Yoon estimated the cost to build such a pilot facility at about $20 million.

“When you look at the list of what (REEs) we import, where we import it from, and what it is used for, it quickly becomes clear that we have a very real problem on our hands,” said Sen. Lisa Murkowski, chair of the Senate’s Energy and Natural Resources Committee hearing Tuesday. “If we let this go unchecked, we will come to a day of reckoning … when we simply cannot acquire a mineral, or when the market for a mineral changes so dramatically, that entire industries are affected.”
