- To make a significant contribution to fighting climate change, the International Energy Agency estimates that 6,000 CCS facilities would be required, each storing one million tonnes of carbon dioxide per year.
- Integrating CCS into existing coal plants is very expensive and difficult.
- It is easier with integrated gasification combined cycle (IGCC) plants, but they are very expensive before you even take CCS into account.
- Commercial scale IGCC plants (not necessarily with CCS) can’t be expected before 2020 – 5 years after global CO2 emissions need to peak.
- Coal plants with CCS will produce 35% – 77% less electricity than those without.
- There are questions about the long-term viability of storing carbon underground.
- Leaks could contaminate water and suffocate people.
- CCS will only be deployed if companies are forced to use it.
In short, people who are counting on CCS to make a big contribution to fighting climate change have a lot to prove, and cannot be reasonably permitted to assume the near-term emergence of the technology as a viable, low-cost option. Until CCS is shown to be safe and feasible on a commercial scale, we simply cannot allow new coal power plants in countries that are serious about dealing with climate change.
