Crunching the emissions for CCS coal versus gas power plants

http://www.guardian.co.uk/environment/blog/2009/may/05/...

The NGOs are saying that our coal policy may still leave emissions higher because of the 75% unabated coal given only 25% CCS required at the outset. But this ignores pre-combustion CCS, which is likely to be used for at least two of the four new plants. Pre-combustion as you know captures 90% of coal emissions from the outset, with no future retrofitting necessary. The effect of pre-combustion CCS means that our policy - even from the outset - will almost certanly lead to lower emissions than the only other realistic alternative of no coal at all (which is what the NGOs would have accepted) and four new gas plants instead.


More at link. And simple math to illustrate the point.
