An interesting debate is under way at the Economist.
The assertion is that CCS (carbon capture and storage) cannot be relied upon for the climate control policies.
Joseph Romm speaking for the assertion believes that vast expense will glean little reward until at least 2030. Whilst the IEA estimates that approx 19% of the emission cuts needed by 2050, can be had by CCS.
This is interesting as the UK PLC has recently pulled out of the Longannet CCS scheme, citing too high a cost for too little a return.
Why not visit the Economist debate here, and follow the proceedings yourself.
