<![CDATA[Grist - Comment Feed for John Edwards would not require that new coal plants sequester their CO2 emissions]]> Grist Comment Feed en Comment #1 by GreenEngineer http://www.grist.org/article/edwards-and-compatibility/ Mon, 10 Sep 2007 08:47:22 -0700 http://www.grist.org/article/edwards-and-compatibility/1 next question

What is their criteria for "compatibility"?  Does this mean IGCC (as it should), or does this include the (currently pie-in-the-sky) possibility of sequestration from conventional plants?

... though to be honest, they didn't strike me as having a very good grasp on the subject. ("What is it, 'IPGG'?" "No, IGCC." "Yeah, that.")

You can gasify the coal before you burn it. This allows you to separate the CO2 from the combustibles but,

Gasifying coal is expensive, so you increase costs for no return if you don't use the gas for something.

I am familiar with only two ideas to get rid of the CO2.  Pump it down old oil wells or into the ocean floor.

Both methods are totally experimental with a low probability of success, and both require your power plant to be built near an old oil well or the ocean so you have a place to pump the CO2.

If this is close to accruate, then building them makes no sense whatsoever. Anyone more knowledgeable out there to fill in the blanks?

In the end, it all comes down to biodiversity. Poison Darts--Protecting the biodiversity of our world

If we build a bunch of new coal plants -- even if they are IGCC plants -- we have to make it work, no matter how much money it costs. The only other alternative is simply shutting them all down.

That's why Edwards' "moratorium" is much weaker than it looks. Allowing a bunch of IGCC plants to be built commits us to making sequestration work, even if it ends up making no economic sense.

Name please?

I would like to verify with that person as well as with others from the campaign. Otherwise, this is unsubstantiated hearsay.
