The UK Committee on Climate Change (Committee on Climate Change, 2011a) described a scenario for power generation in the UK where renewables provided about 40% of electricity generation by 2030, with additional decarbonisation by use of nuclear power (also around 40%) plus 15% from use of CCS. This was based on cost assumptions (Committee on Climate Change, 2011b) that indicated that CCS would be more expensive than nuclear power, the other large-scale low-carbon technology, but less expensive than most of the distributed renewable technologies (i.e. solar, wave, tidal) except for onshore wind and several bioenergy technologies. However, it can be argued that this view of costs (especially capital costs) is significantly over-simplified.
A more sophisticated analysis of many low emission sources of electricity shows that the cost is not a simple, standard figure as has normally been used to represent fossil-fuel-fired power generation in the past – rather there are significant influences on the cost of electricity due to the geographic distribution of the sources (in the case of wind, solar, biomass) and on the size and distribution of the storage facilities (in the case of CCS). Allowing for these factors can make a significant difference to the cost of electricity but has only been attempted in a few studies to date, for example Davison
(2001) for wind power and recent, as yet unpublished, work on CCS. It cannot be assumed that these influences on cost are either negligible or that they are similar for every type of system.
In conclusion it is worth repeating that the cost of CCS is no more than that of many other mitigation options and several studies have shown it could play an important role in keeping down the overall cost of a portfolio of mitigation options designed to achieve deep reductions in emissions. The cost of fitting CCS to individual power plants would be substantial, because typical power stations produce a lot of CO 2 ; to do the same by replacing the power stations with the equivalent effective capacity in wind or solar or other renewables would be even more expensive.
