Carbon Capture and Storage is a Flop… No, It’s A Success!

Will carbon capture and storage ever work?

Fat chance, according to Exxon Mobil’s Energy Outlook, which noted that its high cost and the need for a regulatory framework “presents significant challenges… beyong government-subsidized projects” in the next two decades. Pretty sour.

Actually, it works right now, Mike Morris of American Electric Power, Co. (AEP), the country’s biggest carbon dioxide emitter, tells the The Wall Street Journal today. Carbon capture and storage (CCS) will allow the company to eliminate emissions from its coal-fired plants by 2025.

What gives? Read More »

Climate Change Policy and the “Trillionth Tonne”

banner

Mankind is currently on track to release the 1 trillionth tonne of carbon into the atmosphere in late March of 2045, according to this doomsday clock created by Oxford University’s Myles Allen.

One trillions tonnes (or 3.67 trillion tonnes of CO2) is the total budget for emissions until 2500 if we hope to limit global warming to 2 degree celsius.

We’ve already spent a bit more than half of our emissions budget since the industrial revolution began in 1750. (Here’s the Nature article with Allen’s research.)

The fact that carbon emissions have a cumulative effect, as Shell’s Climate Change Advisor David Hone points out, presents a policy problem that we’re not currently addressing or even really thinking about. Read More »

Warren Buffett Goes Long Coal With BNSF… No, Wait…

Obligatory Train Photo

Is Billionaire Warren Buffett’s $34 billion investment in BNSF railroad actually an investment in coal as the energy of the future?

Burlington Northern Santa Fe railroad carries 1/5th of the nation’s coal, principally from the Rocky Mountain West, which contains the Powder River Basin’s low sulfur coal, to the Midwest.

Moving coal accounted for ¼ of BNSF’s revenue through Q3 of 2009.

The Vine’s Bradford Plumer argues that Buffett, knowing the importance of coal for the railroad’s revenue, is thus betting that “coal’s going to remain a major part of the U.S. energy mix for quite some time…”

Reuters’ John Kemp says much the same.

The Economist plays both sides, arguing that Buffett is “doubling down on the carbon-intensive economy.” Wait, no, maybe he’s planning on “weaning BNSF off coal and moving into other freight areas…”

You can see can see how quickly this discussion devolves into incoherence without any guidance from the Oracle of Omaha himself.

And the problem with oracles, as Julius Caesar discovered, is that they’re awfully vague.

Let’s look at the evidence. Read More »

Exxon Watch: Creating a Niche For Natural Gas in Kerry-Boxer?

As climate change legislation has gone from pie-in-the-sky improbability to a concrete measure that can attract Republican support, it’s instructive to watch Exxon adjust its approach.

Sure, CEO Rex Tillerson is still an official carbon tax supporter, but it appears the company is hedging its bets.

To wit: an op-ed posted on the company’s Web site last week heralds natural gas as an immediate, low-emission solution to America’s energy needs.

There’s some boilerplate in there about a revenue-neutral carbon tax, but that’s just a nod to the company’s official stance. We guess that the real point of this op-ed is to make sure that natural gas has a privileged spot in any climate change legislation, which could revive the cratering price for the commodity.

Growing funding for carbon capture and storage projects

Growing funding, both at the state and federal level, for carbon capture and storage projects could ensure the construction of up to 10 test plants over the next four years, says a recently issued report by Emerging Energy Research.

“As state and federal funding accelerates over the next two years, EER estimates that more than 10 CCS projects, each greater than 100 MW, are positioned to begin construction by 2013 in the US, with a potential combined capacity of more than 4,000 MW,” EER  outlines.

The findings come amidst growing doubt that CCS can transition from scientific theory to become an effective, working technology. For more on that, take a look at this International Energy Agency study, here. Also, take a look at this article.

But EER says there is growing political momentum — and funding — for large-scale testing and deployment of CCS power plants, all be it on a testing phase.

The $787 billion federal stimulus, recently signed into law by President Obama, includes $3.5 billion for CCS projects. Specifically, about $800 million will go to the Department of Energy’s Clean Coal Power Initiative as well as $80 million for carbon sequestration research and development.

At the state level Illinois recently approved energy legislation requiring local utilities and power retailers to supply 5 percent of their electricity from coal plants that capture and sequester CO2.

The Texas legislature is considering to extend tax credits for companies developing plants using IGCC –  Integrated Gasification Combined Cycle –  a carbon sequestration technology that turns coal into cleaner hydrogen. To get the tax credit the proposed legislation mandates IGCC facilities capture and sequester at least 60% of their CO2 emissions.

Pennsylvania and Michigan have also recently introduced CCS funding proposals.

EER estimates that currently there are about 1,500 MW of CCS demonstration projects at some stage of development in the U.S.
