The key takeaway from President Obama’s major climate change announcement this 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 Obamaโs strategy is administered. ย
The day after Obama’s speech, Moniz told Congressย โthe President advocates an all-of-the-above energy strategy and I am very much in tune with this.โ
Whatโs 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 twenty 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 worldโs 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, areย huge.
In May, carbon dioxide levels in the Earthโs atmosphere reached 400 parts per million โ 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 NRDC 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 nationโs total greenhouse gasses. So focusing on power plants is key if emissions are to beย reduced.
Coal currently supplies about 40 percent of American electricity, according to EIA statistics, down from fifty percent in 2005. Coalโs 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 toย 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, thatโs because it is.
Thereโs 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 โthe 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 Presidentโs climate goals.โ
The $8 billion in total subsidies adds up to more than the wind and solar industries combined receive โ and those are industries that have proven themselves to be commercially viable.
Undaunted, Moniz told The New York Times on Thursday that carbon capture and sequestration was a vital part of the countryโs climate change strategy. He called for CCS to be commercialized first for coal-fired power plants. He added that natural gasโ carbon emissions, though half those of coal, are still too high to meet Obamaโs long-term goal of slashing emissions 80 percent from 1990 levels by 2050 โ so he called for the same speculative technology to resolve that problem as well.
The transition to an electric industry that captures its greenhouse gasses instead of releasing them into the atmosphere makes the challenges associated with developing renewables like wind and solar look easy inย comparison.
Professor Vaclav Smil, author of โEnergy Myths and Realities: Bringing Science to the Energy Policy Debateโ has calculated that to sequester just a fifth of current carbon dioxideย emissions:
โโฆ 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 toย build.โ
Carbon capture is also grossly inefficient. โBy some estimates, 40 percent of the energy generated has to go to the carbon capture and sequestration process,โ Josh Galperin, associate director of the Yale Center for Environmental Law and Policy, said after the climate strategy was released. DeSmogโs Kevin Grandia describes some further technical hurdles that carbon sequestration has yet toย 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 โrare circumstances,โ a draft strategy leaked to the press earlier this 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 CO2 from coal plants, touting the potential for so-called โclean coal.โย
โIt’s cheap,โ he told Scientific American when the report was released, โthere’s lots of it and there’s lots of it in places with high demand, namely the U.S., China and India.โ
In 2007, Moniz co-authored an MIT report titled โThe Future of Coalโ that aimed to examine โhow the world can continue to use coal, an abundant and inexpensive fuel, in a way that mitigates, instead of worsens, the global warming crisis.โ
Monizโs faith in carbon sequestration has remained unshaken up to the present day.
โIt’s not going to happen tomorrow, but I believe in this decade we will have demonstrated the viability of large-scale storageโ of carbon-dioxide from industrial operations, he told the Associated Press on Thursday. โThe 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,โ he added.
Meanwhile, broader concerns about the President’s climate plans remain.
โWeโre happy to see the president finally addressing climate changeโ said Bill Snape, senior counsel for the Center for Biological Diversity, โbut the plain truth is that what heโs proposing isnโt big enough, and doesnโt move fast enough, to match the terrifying magnitude of the climateย crisis.โ
And if the clean coal technology Mr. Moniz is counting on doesn’t pan out, prospects may be evenย dimmer.
