The theory is that you attach a big hose to a coal-fired power station's chimney, and pump the CO2 back into empty oilfields.
The Nats, Labour and the Tories think this is a magic bullet to allow business-as-usual power generation. Our position has always been "well, if you can prove it works and is more cost-effective than renewables, it's a possible transitional technology".
But the evidence is growing that CCS simply won't work. The reason is that the CO2 doesn't just magically get itself underground - it has to be pumped, and that takes more energy, specifically about 30% more coal power.
Once you factor in the lifetime consequences of extracting, transporting and burning that extra coal, the nitrogen oxide and sulphur oxide emissions are up to 40% worse (peer-reviewed actual science) than a standard coal plant. That means more acid rain, more ozone destruction, and more water pollution.
In short, Labour, the Nats, and the Tories are going down a dead end. Shouldn't the fact that Arthur Scargill's also on their side have been a bit of a give-away? It's not as if we don't have other perfectly good and genuinely clean technologies that we could be diverting the money towards instead.
