Cheap clean coal now dirty, expensive	David Roberts	13 Apr 2008	Gristmill
The WSJ energy blog points out that skyrocketing demand for coal in the developing world is rapidly driving up the commodity price. (And WSJ proper points out that rising prices for coal mean rising prices for steel.) Meanwhile, Reuters says 'clean coal' is 'elusive' and the head of one of Australia's biggest energy companies -- AGL -- says that coal's days are numbered: ... Michael Fraser said it is unlikely any new coal generators will be built without significa ...

The technologies needed to beat 450 ppm, Part 1 Examining the IPCC's 'portfolio of technologies'	Joseph Romm	10 Apr 2008	Gristmill
In 2007, the IPCC wrote [PDF] in its Working Group III summary (page 16): The range of stabilization levels assessed can be achieved by deployment of a portfolio of technologies that are currently available and those that are expected to be commercialised in coming decades. This assumes that appropriate and effective incentives are in place for development, acquisition, deployment and diffusion of technologies, and for addressing related barriers (high agreement, ...

Darth Vader and Mr. Rogers James Hansen writes to Duke Energy on coal	Guest author	01 Apr 2008	Gristmill
This is a guest post by noted NASA climate scientist James Hansen. ----- The captains of industry, perhaps more than anyone else, have the ability to solve the global warming problem, so they deserve attention. But different strategies are needed for a Mr. Rogers or a Darth Vader. Some may argue that Mr. Rogers, $28M/year chairman of Duke Energy, is just another executive focused on short-term profits, with any concern for his children and grandchildren directed t ...

Is 450 ppm (or less) politically possible? Part 1 We'll need a lot of Socolow and Pacala's wedges	Joseph Romm	01 Apr 2008	Gristmill
The short answer is: 'Not today -- not even close.' The long answer is the subject of this post. Regular readers know that the nation and the world currently lack the political will to stabilize atmospheric concentrations of carbon dioxide at 450 ppm or even 550 ppm. The political impossibility is also obvious from anyone familiar with Princeton's 'stabilization wedges' [PDF] -- and if you aren't, you should be (technical paper here [PDF], less technical one here [ ...

Another entrant in the $1/watt solar sweepstakes Cost of solar cells may be driven down dramatically	David Roberts	26 Mar 2008	Gristmill
Well lookie here! A series of manufacturing process improvements could make the cost of electricity from silicon-based solar cells comparable to today's prices for coal generation within about four years, according to a company emerging out of stealth today. The company, 1366 Technologies, will be using technologies developed in MIT labs to reduce the manufacturing costs of standard-issue multi-crystalline silicon solar cells. They say they can ultimately reduce ...

Why FutureGen had to die The blind alley of more coal	John McGrath	25 Mar 2008	Gristmill
Thomas Homer-Dixon, whose book I adore, has written an op-ed in The Globe and Mail arguing in favor of large government investments in carbon capture and sequestration technology. His advocacy of CCS has long confused me -- my reading of his book suggested (to me, anyway) that large-scale CCS was precisely the kind of technology we should avoid like the plague. To recap: Homer-Dixon builds on the work of Joseph Tainter, who argues that societies respond to pressures ...

Run your car on coal? Maybe not CTL fuels: still a bad idea	Guest author	25 Mar 2008	Gristmill
The following is a guest essay from Peter Montague, executive director of the Environmental Research Foundation. ----- As the price of oil rises, coal company executives smell a huge opportunity: they are planning to ramp up a new global industry to turn coal into liquid fuels (diesel, kerosene and jet fuel), plus basic feedstocks for the chemical industry to make plastics, fertilizers, solvents, pesticides, and more. The coal-to-chemicals industry is already going ga ...

Thought: Control Waxman and Markey introduce bill to ban new dirty coal plants		11 Mar 2008	News
Posted at 10:09 AM on 11 Mar 2008 House Representatives Henry Waxman (D-Calif.) and Ed Markey (D-Mass.) have introduced the "Moratorium on Uncontrolled Power Plants Act of 2008," which would do pretty much what it sounds like: prevent new coal plants in the U.S. unless they're built with advanced pollution controls. Says Waxman, "The altemative is senseless -- locking in decades of additional global war ...

Coal: getting expensiver	Sean Casten	11 Mar 2008	Gristmill
More details on the new, really-really-expensive AEP coal plant in West Virginia. It seems like just yesterday that I wrote that the 17 percent rate increase announced by AEP would not be the last one, given the cost of this plant. Two days later, here they come. Specifically, 'Customers could start paying as early as next year with rate hikes starting at $1 per month in 2009 and eventually climbing to $7.70 per month. AEP customers could pay nearly $160 million du ...

Climos Def New company wants to seed ocean with iron to sequester carbon		05 Mar 2008	News
Posted at 12:24 PM on 05 Mar 2008 Weeks after ocean-seeding company Planktos bit the iron dust, a startup called Climos is plowing ahead with a similar business plan: seed the ocean with iron dust to stimulate the growth of CO2-gobbling plankton, then sell offsets for the sequestered carbon. Climos has announced $3.5 million in venture capital and is backed by reputable investors: Tesla Chair (n�e Pay-Pal cofounder) Elon Mu ...

Chris Anderson: Paper mags are better on carbon than websites	David Roberts	05 Mar 2008	Gristmill
From 1998 until 2006, the Wired website and Wired magazine had different owners and were run separately. In 2006, Cond� Nast bought the website back and reunited them. I've heard rumors that there were some tensions along the way. I can't help but wonder if those tensions are behind an odd post from Chris Anderson, editor-in-chief of Wired magazine, claiming that Wired-the-magazine beats Wired-the-website on a carbon basis. The claim is mostly based on the fact that ...

Alternate futures Two huge power plants offer different paths forward	David Roberts	22 Feb 2008	Gristmill
In Sweetwater, Texas, a company called Tenaska has applied to build what will be the nation's first bona fide "clean coal" plant -- an IGCC plant that will capture and sequester CO2 emissions. (Said emissions will be used to pump more oil out of the Permian Basin oil fields, which will then be burned and create more CO2, but who's counting?) The 600MW plant is projected to be completed in 2014. Meanwhile, Spanish engineering firm Abengoa has signed a deal w ...

Quick, change more lightbulbs! China kicks off the coal-to-liquids rush	David Roberts	21 Feb 2008	Gristmill
Looks like China is about to uncork the CTL genie, opening a plant to produce liquid fuel from coal. This won't be the last: A study last year by the Chinese Academy of Sciences said: 'Production of liquid fuels from coal is practically the most feasible route to cope with the dilemma in oil supply.' It concluded: 'Establishing large-scale CTL [coal-to-liquids] plants on the pitheads of several main coalfields is feasible and competitive when oil price is well o ...

Carbon on the half shell A lighthearted look at biosequestration	Erik Hoffner	21 Feb 2008	Gristmill
A semi-recent issue of High Country News carried a feature on the deep-rock carbon sequestration potential in the northwestern U.S.: it's maybe possible to inject CO2 captured from power plants into the basalt that underlies the region, producing inert calcium carbonate. If so, there's apparently enough basalt to capture centuries of the region's carbon emissions. It's safe to say the research has its doubters. And carbon sequestration in general deserves the hairy ...

Turning CO2 into gasoline A new way to waste energy	Joseph Romm	21 Feb 2008	Gristmill
Last week, the NYT's Andy Revkin blogged about a federal laboratory that says it can take atmospheric carbon dioxide and turn it into gasoline: One selling point with Los Alamos's 'Green Freedom' concept, and similar ones, is that reusing the carbon atoms in the captured CO2 molecules as a fuel ingredient avoids the need to find huge repositories for the greenhouse gas. The only problem with that exciting statement is that it is almost certainly not true, a ...

Vaporware	David Roberts	04 Feb 2008	Gristmill
It's a few days old now, but don't miss Tyler Hamilton's column on CCS in the Toronto Star. It focuses on Canada, but the story is basically the same: despite all the talk and hype, carbon capture and storage is a long, long way off, subject to enormous logistics problems, and uncertain to succeed even under the most optimistic projections.

Flipflopping on FutureGen Bush drops mismanaged 'NeverGen' clean coal project	Joseph Romm	31 Jan 2008	Gristmill
For those remaining seven or eight three or four people who still buy the Bush rhetoric that he cares about global warming and is committed to addressing the problem with new technology, Exhibit 435C for the prosecution is the just-canceled 'clean coal' project called FutureGen. [Amusing anecdote for FHA (Future Historians of America): I once had a boss at the U.S. Department of Energy who practiced repeating 'clean coal' in front of a mirror so as not to break out ...

PastGen Department of Energy backs away from funding FutureGen project		29 Jan 2008	News
Posted at 5:04 PM on 29 Jan 2008 Well let us just pick our grinning jaws up off the floor: The U.S. Department of Energy has told lawmakers that it plans to pull funding for FutureGen, its ambitious and crazily expensive "clean coal" demonstration plant. The feds had planned to cover some three-quarters of the $1.8 billion price tag, and cited ballooning costs as its reason for backing out. The announcement pissed ...

Shorter winters weaken forest carbon sinks New study says trees are absorbing less CO2 than predicted	Anna Fahey	04 Jan 2008	Gristmill
Forests have gained a lot of attention in the climate change conversation because of their ability to suck carbon out of the atmosphere. Individuals can buy 'reforestation' offsets on the internet. There's talk of including credits for carbon stored in trees and wood products as part of many proposed cap-and-trade systems. Cities and businesses are even planting trees as part of their efforts to slow climate change. But forest ecosystems are, by their nature, unpredictabl ...

The Choice of an Old Generation Peabody Energy partners on Chinese		03 Jan 2008	News
"clean coal" project Posted at 2:01 PM on 03 Jan 2008 Coal behemoth Peabody Energy -- a partner in the infamous FutureGen -- will join with Chinese equity partners to build China's first "clean coal" plant, dubbed GreenGen. (We just threw up in our mouths a little.) Partners say the project will provide near-zero emissions, and the first phase is expected to be on line by 2009. Isn't optimism cute? source:� P ...

Pity West Virginia The backlash against coal has not made it to the halls of power in WV	David Roberts	11 Dec 2007	Gristmill
There are some heartening recent stories from the land of Coal Backlash. Portland-based PacifiCorp is giving up on new coal plants entirely -- not for environmental reasons but for economic ones. (Lesson: coal isn't cheap.) Missouri is probably the most hostile state for climate activists. It ranks among the top five states for emitting CO2, its emissions are growing faster than any other state's, 85% of its power comes from coal, it is 46th out of 50 state in terms o ...

Tracking Lieberman-Warner Sanders gets smacked down	Brian Beutler	05 Dec 2007	Gristmill
Sanders' amendment -- Sanders #3 -- would have required CCS-equipped plants to sequester at least 85 percent of their pollution in order to be eligible for additional free allowances. That's what the bill used to mandate, before it was changed earlier this month. Sanders tried to change it back and was voted down with 13 'nays,' including one from his usual ally Barbara Boxer. Sanders' support of this bill may be irrelevant to its passage through committee. But if ...
