It looks like Eon are waking up again after their winter hibernation where they 'shelved' plans for a new coal fired power station at Kingsnorth. Plans have now been submitted for a pipeline to take the CO2 away so that it can be burried under the North Sea, and news in yesterday's Kent on Sunday was of a deal with the government to get 'tens of millions' to draw up plans for the technology. Sadly, it looks like Kingsnorth did not go away.
Carbon capture and storage is unproven. Building a new coal fired power station will ensure that more CO2 is released each year than Ghana. Adding CCS may reduce the CO2 emissions in the medium term if it works, but it still be pumping massive amounts into the atmosphere to start with and even if / when it is working it will only capture 90% of the CO2. While 90% is a significant proportion from a technical point of view, it still leaves the power station responsible for an equivalent of 10% of the CO2 emissions that Ghana produces.
Ignoring the years of testing where 100% of CO2 will be emitted, ignoring the embodied energy in the plant, it is still clear that this is an unviable and overly expensive way of meeting the energy gap. The tens of millions of pounds could be much better spend on efficiency and renewable energy. Remember, coal is not renewable and while it won't run out in our lifetime, it will run out. Renewable energy is, er... renewable.
