The place to look is the MIT sequestration study (came out this year).

http://web.mit.edu/coal/

IGCC is, from memory, about 42-44% efficient, v. about 32% for a supercritical coal station, and maybe 35% for an ultra supercritical PC station. (I'm doing that out of memory).

What MIT says, is that it is not clear whether IGCC is the best technology for sequestration, and a strategy of subsidising IGCC stations *without sequestration* for future retrofitting, in preference to USC PC, is wrong. That was the main 'new news' for me.

I'll have to look at that.  Unfortunately, I'm swamped with work this week (just when I need to look at that energy bill). :(
