The authors regret. In this manuscript, we stated that the Hg emissions from oxy-fuel combustion are an important issue to deal with in view of the forthcoming implementation of oxy-fuel combustion at an industrial scale. The reason why we made that statement is because in this study we wanted to evaluate the abatement capacity of a demonstration oxy-fuel plant for Hg. However, we would like to clarify that the fundamental of oxy-fuel combustion is to increase the partial pressure of CO2 in the flue gas in order to make its sequestration and compression easier and more cost effective. The requirements in an oxy-fuel power plant are based on the CO2 processing/purification, transport, storage and environmental regulation, instead of the air emission limits. The authors would like to apologise for any inconvenience caused.
