carbon sequestration

Imagine if in a poverty-stricken sector of the equatorial band, littered with acidic soils barely fit for farming, there were jet-black patches of dirt, seeded with charcoal and so fertile that they could be planted continuously for over 40 years without applying fertilizer.

Then imagine that those patches were so loaded with carbon that they had six to seven times the amount of carbon per pound of the surrounding soils, that Western scientists could partially replicate the process through which the black earth was made, and that by burying carbon in earth they could augment soil fertility and, perhaps, leach carbon out of the atmosphere and reverse global warming.

Perhaps the jig is already up—too much detail. What we’re talking about is terra preta, or more colloquially, biochar, the Amazonian miracle soil.

NASA Climatologist James Hansen has endorsed terra preta—literally black earth—as a carbon “draw-down strategy.” British chemist James Lovelock, originator of the Gaia hypothesis, says it is the “one way we could save ourselves.”

So let’s check it out. But first, what is it?

In part one of this two-part post, I suggested four principles that President-elect Obama’s economic team should follow as they create an economic recovery package. To sum up, America needs long-term investments in a new energy economy, with every dollar used strategically to solve several problems at once, including energy security, economic stability and a rapid reduction in greenhouse gas emissions.

Obama clearly understands this prescription. He has announced that he will champion a two-year recovery package to create 2.5 million jobs, in part by "creating the clean energy infrastructure of the twenty-first century." To his credit, he told governors and international leaders meeting in California last week that our economic mess will not deter his commitment to this investment.

"I promise you this," he said in a taped address. "When I am president, any governor who's willing to promote clean energy will have a partner in the White House. Any company that's willing to invest in clean energy will have an ally in Washington. And any nation that's willing to join the cause of combating climate change will have an ally in the United States of America."

The question is whether the Congress and the American people will support a recovery package designed not just for short-term stimulus, but for long-term health.

Clean coal isn’t having much luck.

The latest project casualty is a carbon capture and storage plant planned for Kwinana, Australia – south of Perth.

BP pulled the plug on the $2 billion venture on account of an unforeseen geological defect in the area: The leaky rock formations can’t seem to seal in CO2 for the long-term.
