New power plants must have zero CO2 emissions
A new provincial policy in British Columbia, Canada, requires new coal-fired power plants in the province to emit no carbon dioxide. This is a very progressive regulation that will hopefully challenge other governments to consider similar measures. According to Richard Neufeld, British Columbia’s energy minister, the policy calls for ‘the best available technology’.

A thorough assessment
In August, the German Federal Environment Agency released its report "Assessment of Technologies for CO2 Capture and Storage". The report presents the results of a research project conducted by the Fraunhofer-Institut in Karlsruhe.
Capture, transport, storage
The report compares the three main technologies for capture: pre-combustion capture, post-combustion capture, and oxy-fuel combustion. It also investigates the consequences of CO2 capture on the emissions, efficiency, and operational cost of power stations, and it analyses the impact of CO2 transport to the storage site. Finally, various possibilities for long-term storage were studied.
