(WASHINGTON) — President Donald Trump on Tuesday night told supporters at a rally in Phoenix that “clean coal” was back. Only his description of “clean coal” was scientifically wrong.
“We’ve ended the war on beautiful, clean coal and it’s just been announced that a second brand new coal mine where they’re going to take out clean coal – meaning they’re taking out coal, they’re
going to clean it – is opening in the state of Pennsylvania,” Trump said.
The president’s comment puzzled both scientists and people with an understanding of how coal mining works.
“He clearly doesn’t know what he’s talking about,” said Pieter Tans, the lead scientist of the Global Greenhouse Gas Reference Network of the National Oceanic and Atmospheric Administration in
“It sounds like he thinks that they’re going to wash the coal,” Tans told ABC News. “It doesn’t make any sense.”
He added, “The concept of ‘clean coal’ is “industry propaganda.”
Tuesday was not the first time Trump has referred to “clean coal” in his speeches.
At a February 2016 rally in Virginia, Trump said, “Clean coal is coming back,” and took a dig at China’s coal production practices.
“We sell coal, the coal mines are dying but the only coal we give is coal to China. Do you think they clean the coal? Believe me, they don’t,” he said.
During the second presidential debate, Trump mentioned it again but didn’t talk about what it was or how it would help the coal industry.
“Hillary Clinton wants to put all the miners out of business. There is a thing called clean coal. Coal will last for 1,000 years in this country,” he said last October.
Steve Clemmer, the energy research director at the Union of Concerned Scientists, said Trump’s clean coal references show that he does not have an understanding of the technology.
“Every time he refers to the world ‘coal’ he puts the world ‘clean’ in front of it. Or ‘beautiful,’” Clemmer told ABC News. “That signals to me that he doesn’t understand what most people refer to
clean coal as.”
He continued, “The way that most people refer to ‘clean coal’ is the process of removing the carbon emissions from the coal and injecting them into geologic formations to address the impact that
coal has on climate change.”
According to Paul Bailey, the CEO of the American Coalition for Clean Coal Energy, “clean coal technology” was first used by former Sen. Robert Byrd, D-W.V., in the 1980s. However, that term has
become shortened by many to just “clean coal.”
“The term ‘clean coal’ and ‘clean coal technology’ have gotten conflated,” he explained.
“So when people refer to ‘clean coal’ whether they know it or not they’re really referring to ‘clean coal technology,’” Bailey told ABC.
Clean coal technology refers to the advancements that have been made in the past several decades to limit the amount of air pollution created as a result of coal mining.
Bailey denied that his organization uses the term “clean coal” as propaganda and said he never considered that people may interpret Trump’s frequent references to “clean coal” as a type of coal
that is cleaner than others.
“There’s no such thing as clean coal. If you want to clean up coal you’ve got to burn it and capture the particles and the mercury will come out anyway as a gas,” according to Tans.
U.S. production of coal has increased more than 14 percent year-to-date compared to the same time frame in 2016, the U.S. Energy Information Administration said. West Virginia, Pennsylvania and
Wyoming have all experienced strong bumps in coal production since the Trump presidency.
“As with many of Trump’s asinine proposals, his insistence on promoting coal is a big step backwards,” said Pushker Kharecha, the deputy director of the Climate Science, Awareness and Solutions
program at Columbia University.
Kharecha noted that “coal is by far the dirtiest energy source in terms of both greenhouse gas emissions and fatal particulate emissions. In the US, coal plants are responsible for the large
majority of both of these emission types.”
