Shell buys Canadian carbon capture firm

Shell has bought a Candian company that specialises in technology for cleaning up gas emissions. Cansolv, which also has offices in China, has a scrubbing system to remove sulphur dioxide from combustion gases as well as carbon dioxide capture technologies.

Greg Lewis, the president of Shell Global Solutions International, said: "We must 'learn by doing' in order to reduce costs, accelerate technology development and ultimately make carbon capture and storage commercially viable on the back of emissions trading schemes."
