Renewables Aren’t Enough. Clean Coal Is the Future

Proof that good things don’t always come in nice packages can be found by taking the fast train from Beijing to Tianjin and then driving to the coast. Tianjin, China’s third-biggest city, originated as Beijing’s port on the Yellow Sea. But in recent years Tianjin has reclaimed so much of its muddy, unstable shoreline that the city has effectively moved inland and a new, crazily active port has sprung up at the water’s edge. In this hyper-industrialized zone, its highways choked with trucks, stand scores of factories and utility plants, each a mass of pipes, reactors, valves, vents, retorts, crackers, blowers, chimneys, and distillation towers—the sort of facility James Cameron might have lingered over, musing, on his way to film the climax of Terminator 2.

Among these edifices, just as big and almost as anonymous as its neighbors, is a structure called GreenGen, built by China Huaneng Group, a giant state-owned electric utility, in collaboration with half a dozen other firms, various branches of the Chinese government, and, importantly, Peabody Energy, a Missouri firm that is the world’s biggest private coal company.

By Western standards, GreenGen is a secretive place; weeks of repeated requests for interviews and a tour met with no reply. When I visited anyway, guards at the site not only refused admittance but wouldn’t even confirm its name. As I drove away from the entrance, a window blind cracked open; through the slats, an eye surveyed my departure. The silence, in my view, is foolish. GreenGen is a billion-dollar facility that extracts the carbon dioxide from a coal-fired power plant and, ultimately, will channel it into an underground storage area many miles away. Part of a coming wave of such carbon-eating facilities, it may be China’s—and possibly the planet’s—single most consequential effort to fight climate change.

Because most Americans rarely see coal, they tend to picture it as a relic of the 19th century, black stuff piled up in Victorian alleys. In fact, a lump of coal is a thoroughly ubiquitous 21st-century artifact, as much an emblem of our time as the iPhone. Today coal produces more than 40 percent of the world’s electricity, a foundation of modern life. And that percentage is going up: In the past decade, coal added more to the global energy supply than any other source.

Nowhere is the preeminence of coal more apparent than in the planet’s fastest-growing, most populous region: Asia, especially China. In the past few decades, China has lifted several hundred million people out of destitution—arguably history’s biggest, fastest rise in human well-being. That advance couldn’t have happened without industrialization, and that industrialization couldn’t have happened without coal. More than three-quarters of China’s electricity comes from coal, including the power for the giant electronic plants where iPhones are assembled. More coal goes to heating millions of homes, to smelting steel (China produces nearly half the world’s steel), and to baking limestone to make cement (China provides almost half the world’s cement). In its frantic quest to develop, China burns almost as much coal as the rest of the world put together—a fact that makes climatologists shudder. (...)

Which brings me, in a way, back to the unwelcoming facility in Tianjin. GreenGen is one of the world’s most advanced attempts to develop a technology known as carbon capture and storage. Conceptually speaking, CCS is simple: Industries burn just as much coal as before but remove all the pollutants. In addition to scrubbing out ash and soot, now standard practice at many big plants, they separate out the carbon dioxide and pump it underground, where it can be stored for thousands of years.

Many energy and climate researchers believe that CCS is vital to avoiding a climate catastrophe. Because it could allow the globe to keep burning its most abundant fuel source while drastically reducing carbon dioxide and soot, it may be more important—though much less publicized—than any renewable-energy technology for decades to come. No less than Steven Chu, the Nobel-winning physicist who was US secretary of energy until last year, has declared CCS essential. “I don’t see how we go forward without it,” he says. (...)

Coal is MEGO—until you live near it. MEGO is old journalistic slang for “my eyes glaze over”—a worthy story that is too dull to read. In America, where coal is mostly burned far out of sight, readers tend to react to the word coal by hitting Close Tab.

But people in Hebei don’t think coal is MEGO, at least in my experience. Hebei is the province that surrounds Beijing. When the capital city set up for the 2008 Olympics, the government pushed out the coal-powered utilities and factories that were polluting its air. Mostly, these facilities moved to Hebei. The province ended up with many new jobs. But it also ended up with China’s dirtiest air.

Because I was curious, I hired a taxi to drive in and around the Hebei city of Tangshan, southeast of Beijing. Visibility was about a quarter mile—a good day, the driver told me. Haze gave buildings the washed-out look of an old photographic print. Not long ago, Tangshan had been a relatively poor place. Now the edge of town held a murderer’s row of luxury-car dealerships: BMW, Jaguar, Mercedes, Lexus, Porsche. Most of the vehicles were displayed indoors. Those outside were covered with gray crud.
