The pilot plant has been built in British Columbia and is extracting about a tonne of CO2 every day A Canadian company, backed by Bill Gates, says it has reached an important threshold in developing technology that can remove CO2 from the air. Carbon Engineering has published a peer-reviewed study showing that they can capture carbon for under $100 a tonne. This would be a major advance on the current price of around $600 per tonne. The company says their immediate goal is to produce synthetic liquid fuels made from carbon and renewable energy. Science sceptics Technological “fixes” to the carbon emissions driving climate change have always been regarded with some suspicion by scientists. Plans to build solar shields in space or to seed the seas with materials to soak up carbon have been seen as dangerous and a distraction to the more mundane but difficult task of getting […]
