Obama Administration to Rely on 'Clean Coal' and Unproven Sequestration to Combat Climate Change
By Sharon Kelly
The key takeaway from President Obama's major climate change announcement last week was his intent to batten down on coal. But if history is any indication, the man Mr. Obama selected to run the Department of Energy may have different plans.
Ernest J. Moniz has a long history of supporting coal-powered electricity, staking his arguments in favor of coal on a technology that remains entirely unproven: carbon capture and sequestration (CCS).
Mr. Moniz will be in a uniquely influential position when it comes to confronting these problems. President Obama announced that he would rely on executive agencies instead of Congress, so Mr. Moniz's Energy Department will play a crucial role in determining precisely how Obama's strategy is administered.
The day after Obama's speech, Moniz told Congress “the President advocates an all-of-the-above energy strategy and I am very much in tune with this."
What's wrong with an all-of-the-above strategy? It extends reliance on fossil fuels, at a time when scientists warn that we can only burn 20 percent of current reserves before the world tips past the crucial 2 degree Celsius point. Beyond two degrees, some of the most devastating impacts of global warming will be felt. Keep in mind that, if all of the world's coal is burned, global temperatures could rise by a jaw-dropping 15 degrees Celsius, a study published in the prestigious journal Nature last year concluded.
The stakes, when it comes to controlling American greenhouse gas emissions, are huge.
In May, carbon dioxide levels in the Earth's atmosphere reached 400 parts per million—the highest level of carbon dioxide ever recorded in human history. Last year, the continental U.S. experienced its hottest year on record, and the Natural Resources Defense Council estimates that climate-related disasters like crop loss, wildfires and floods cost the nation roughly $140 billion last year alone, with much of the tab picked up by taxpayers.
Power plants are the single largest source of American carbon dioxide emissions, accounting for a third of the nation's total greenhouse gases. So focusing on power plants is key if emissions are to be reduced.
Coal currently supplies about 40 percent of American electricity, according to Energy Information Administration statistics, down from 50 percent in 2005. Coal's decline comes as natural gas from fracking (which has its own worrisome climate impacts, measured in methane rather than carbon dioxide), wind and solar, have risen in their share of the U.S. electric portfolio. Since the beginning of 2010, 145 coal-fired power plants announced plans to retire.
But the Department of Energy is focused not on retiring more of these plants, pinning its hopes instead on developing new technologies to make coal cleaner. The plan in rough form, involves collecting carbon dioxide emitted by power plants and burying it, forever, underground.
If that sounds like a heck of a challenge, that's because it is.
There's not a single large commercially-operating carbon sequestration plant anywhere in the world.
That's despite over $25 billion in government subsidies worldwide from 2008 to 2012.
Nevertheless, Mr. Moniz told Congress that “the Administration has already committed about $6 billion to [carbon capture and sequestration] demonstrations, and success of the forthcoming projects will be a critical step toward meeting the President's climate goals."
The $8 billion in total subsidies adds up to more than the wind and solar industries combined receive—and those are industries that have proven themselves to be commercially viable.
Undaunted, Moniz told The New York Times that CCS was a vital part of the country's climate change strategy. He called for CCS to be commercialized first for coal-fired power plants. He added that natural gas' carbon emissions, though half those of coal, are still too high to meet Obama's long-term goal of slashing emissions 80 percent from 1990 levels by 2050—so he called for the same speculative technology to resolve that problem as well.
The transition to an electric industry that captures its greenhouse gases instead of releasing them into the atmosphere makes the challenges associated with developing renewables like wind and solar look easy in comparison.
Professor Vaclav Smil, author of Energy Myths and Realities: Bringing Science to the Energy Policy Debate has calculated that to sequester just a fifth of current carbon dioxide emissions:
"... we would have to create an entirely new worldwide absorption-gathering-compression-transportation-storage industry whose annual throughput would have to be about 70 percent larger than the annual volume now handled by the global crude oil industry whose immense infrastructure of wells, pipelines, compressor stations and storages took generations to build."
Carbon capture is also grossly inefficient. "By some estimates, 40 percent of the energy generated has to go to the carbon capture and sequestration process," Josh Galperin, associate director of the Yale Center for Environmental Law and Policy, said after the climate strategy was released. DeSmog's Kevin Grandia describes some further technical hurdles that carbon sequestration has yet to overcome.
In a key indication of how shaky the science is behind carbon sequestration, not even the World Bank will fund it. Concerns about climate change led the Bank to restrict its financial support for coal projects except in “rare circumstances," a draft strategy leaked to the press last week indicates. In a glaring omission, the strategy says nothing about carbon capture and sequestration as an alternative.
None of this seems to matter to Mr. Moniz, whose support of the coal industry and faith in sequestration has been longstanding.
A 2009 report he helped produce focused on how to reduce carbon dioxide from coal plants, touting the potential for so-called "clean coal."
"It's cheap," he told Scientific American when the report was released, "there's lots of it and there's lots of it in places with high demand, namely the U.S., China and India."
In 2007, Moniz co-authored an Massachusetts Institute of Technology report titled The Future of Coal that aimed to examine “how the world can continue to use coal, an abundant and inexpensive fuel, in a way that mitigates, instead of worsens, the global warming crisis."
Moniz's faith in carbon sequestration has remained unshaken up to the present day.
"It's not going to happen tomorrow, but I believe in this decade we will have demonstrated the viability of large-scale storage" of carbon dioxide from industrial operations, he told the Associated Press recently. “The president made clear that we anticipate that coal and other fossil fuels are going to play a significant role for quite some time on the way to a very low carbon economy," he added.
Meanwhile, broader concerns about the President's climate plans remain.
“We're happy to see the president finally addressing climate change" said Bill Snape, senior counsel for the Center for Biological Diversity, “but the plain truth is that what he's proposing isn't big enough, and doesn't move fast enough, to match the terrifying magnitude of the climate crisis."
And if the clean coal technology Mr. Moniz is counting on doesn't pan out, prospects may be even dimmer.
