Abstract Information :
The Emissions Trading Scheme (ETS) makes provision for Carbon Capture and Storage (CCS), using a mass balance approach that requires metering and purity measurement of the captured CO2 that is sent to storage. Whilst the prescribed approach delivers a high relative uncertainty in the residual CO2 in the flue gas that is emitted to air post-capture there is only a modest uncertainty in the carbon capture efficiency. The ETS therefore provides a driver for minimising metering uncertainties. Alternatively, measuring the flue gas CO2 emissions (stack flow and CO2 concentration post-capture) poses a number of challenges for CEMS and requires measurement or estimation of other emission sources such as bypass stacks or vents. The implications for different industrial sectors will be explored.
