Carbon Sequestration: A Surreal Carbon Solution

Writing in the New York Times, here, Joe Nocera, says,

Sometime this summer, in Odessa, Tex., the Summit Power Group plans to break ground on a $2.5 billion coal gasification power plant. Summit has named this the Texas Clean Energy Project. With good reason.

The people behind this project want people to believe that the energy the plant produces is clean. Mr. Nocera continues.

Part of the promise of this power plant is its use of gasified coal; because the gasification process doesn’t burn the coal, it makes for far cleaner energy than a traditional coal-fired plant.

The plant doesn’t burn SOLID coal. It gassifies the coal, then burns the gas. It’s still burning the coal. Only this process uses energy to gassify the coal. It then uses more energy to capture and sequester 90% of the carbon. Think, Mr. Nocera, how can this make CLEANER? Answer: It Can’t and it Doesn’t. But it can – and does – make it more expensive.

And what about the Arsenic, Mercury, Uranium that are embedded in coal? And the processes that dig coal out of the ground? Refer to Appalachian Voices for more on mountaintop removal.

"Beyond Fuel" at the Space Coast Green Living Festival

Green Living Festival

Tweet I am presenting “Beyond Fuel: From Consuming Natural Resources to Harnessing Natural Processes,” a discussion of the hidden costs, or “economic externalities,” of nuclear power, coal, and oil, and the non-obvious benefits of wind, solar, marine hydro and efficiency at the Sp ace Coast Green Living Festival, Cocoa Beach, Florida, Sept 17, 2011.

The festival is sponsored by the Cocoa Beach Surfrider Foundation and the Sierra Club Turtle Coast Group. It will be at the Cocoa Beach Courtyard by Marriott.

Clean Energy, Good Jobs, and a Vibrant Economy … But

courtesy NASA (our tax dollars at work)

Tweet It sounds too good to be true:

*   100 gigawatts of offshore wind, $300 Billion,
*   100 gw of landbased wind, $200 Billion,
*   75 gw of solar, $300 Billion,
*   75 gw of geothermal, $200 Billion.
*   200 gigawatt equivalents of efficiency – $200 Billion.
*   100 & Clean, Renewable, Sustaianble Energy: 1.2 Trillion.
*   2.7 Million New Jobs and a Healthy Economy: Priceless!

This is happening, slowly, inexorably, by the “invisible hand of the market.” But it will happen faster if the “invisible mind of the community” acts. This means the government!

Earth Day, 2011, Where Are We?

Earth Day, 2010, I looked to the future on Popular Logistics. In 2009, I wrote about water pollution and agricultural waste in the Chesapeake. Today I am looking at the present and recent past. While a comprehensive look at where we are can be found on the web pages of the World Watch Institute, the New York Times, and the World Factbook of the Central Intelligence Agency, I want to make a few points.

Our energy policy is “when you flip a switch, the juice gotta flow.” It ain’t magic. It’s engineering and classical physics, with an understanding of radioactive fission and decay and a profound lack of long term thinking. It ain’t magic, but it might as well be. But we really need to base our energy policy on an understanding of ecological economics and sustainability.

We’ve had a few problems with nuclear power and fossil fuel in the last few years. Yet, there’s some light on the horizon.

21 Century Energy or Business As Usual?

NY Times Special (Business As Usual) Energy Section

Clifford Krauss’ “Can We Do Without the Mideast?” sets the tone for the “Special Energy Section” in the NY Times, March 31, 2011. “The path to independence – or at least an end to dependence on the Mideast – could well be dirty, expensive and politically explosive.” Is this an April Fool’s Day joke? The path to sustainable energy requires vision and hard work. a solar array on every roof and insulation in every wall and every attic. It will be better for the economy, better for the environment, and better for ourselves, our children, and our grandchildren. Continue reading →

Coal Plant With Carbon Sequestration

Tweet SCS Energy, of Concord, Mass., wants to build a new coal plant in Linden, NJ.

18cleanmap According to Kate Galbraith, reporting in the NY Times, “A Plan for U. S. Emissions to Be Buried Under Sea“, 90% of the carbon dioxide will be captured, compressed, pumped thru a 24 inch diameter pipe, approximately 70 miles south-east, past Staten Island, New York, and Middlesex, Monmouth, and Ocean Counties in New Jersey, to a point 25 or 30 miles east of Atlantic City, New Jersey,and injected by a well drilled a mile beneath the sandstone floor of the Atlantic Ocean. The Atlantic is about a half mile deep at that point.

Gailbraith reports that the plant could cost $5 billion if completed on time and on budget. And it will need $100 million a year in Federal Government subsidies, which amounts to another $4 billion over the plant’s 40 year operating life span.

The carbon sequestration is projected to use 25% to 40% of the energy released from burning coal, so the 750 megawatt plant will be a 450 to 562.5 mw plant. That’s $16 Billion to $20 Billion per gigawatt or $16 to $20 per watt, depending on the overhead costs, of sequestering the carbon.

Solar is roughly $6.50 per watt with no subsidies, no fuel costs, very low maintenance, and no loss in transmission. Offshore Wind is $3.00 per watt, with no fuel costs.
