New Technology Unveiled to Cut Cost of Removing CO2 from Air

Amid perpetual efforts to save the environment, a Canadian company Carbon Engineering supported by Bill Gates has attained significant success. The company has developed a technology that can remove CO2 from the air.

The company has published a peer-reviewed study that can capture a tonne of carbon for less than US$100. This would be a major boost to the current rate of around US$600 for every tonne. The company stated that the immediate aim is to manufacture synthetic liquid fuels made from carbon and renewable energy.

Technological Fixes Seen with Apprehension in Scientific Community

In general, scientists have always been apprehensive about technological fixes for carbon emissions that are causing climate change. Earlier, plans to construct solar shields in space or to line the seas with materials that can soak up carbon have been observed to be dangerous and a distraction than the difficult task of making people cut their emissions. Howbeit, plans to trap CO2 directly from the atmosphere has been regarded more substantial.

First developed by a scientist named Klaus Lackner in the mid-1990s, some technology companies have built costly prototypes of carbon removing devices. Another initiative carried out last year by a Swiss company named Climeworks involved direct capture phenomenon. The system extracted carbon and supplied it to a nearby greenhouse to fertilize cucumbers and tomatoes. In this regard, Canadian firm Carbon Engineering have taken a big step forward to cut the cost of direct air extraction.

Funded by Canadian oil sands industrialist Norman Murray Edwards and Microsoft’s Bill Gates, the plant set up in 2009 has been operational since 2015, and captures about one tonne of CO2 each day.
