Here is another Monument to the Madness of CCB (carbon capture and burial) – it needs a lot of energy – currently estimated to require 30% of the output of a power station.
So in order to satisfy the existing market for electricity, we would have to build a new power station for every three existing ones just to provide the power to capture and bury, not just the CO2 from the existing ones, but also from the new one as well.
Most coal fired power stations are about 33% efficient. Put simply, they burn 3 tonnes of coal to get the equivalent energy of 1 tonne. With CCB, they will now burn 4 tonnes of coal and increase CO2 emissions by 33% for the same useful output.
If however we spend the money required for CCB on increasing the efficiency of thermal power stations even to a modest 50%, they would only need to burn 2 tonnes of coal to get the equivalent energy of 1 tonne and that alone will reduce CO2 emissions by 33%.
Combined cycle is already at 50% and China has been developing super critical boiler temperatures which they claim will be 50% efficient.
But what does Government do? They introduce a tax, as a solution which may not work, for a problem which may not exist.
