In the southern Indian city of Tuticorin, locals are unlikely to suffer from a poorly risen cake. That’s because a coal-fired thermal power station in the area captures carbon dioxide and turns it into baking soda.
Carbon capture schemes are nothing new. Typically, they use a solvent, such as amine, to catch carbon dioxide and prevent it from escaping into the atmosphere. From there, the CO2 can either be stored away or used.
But the Guardian reports that a system installed in the Tuticorin plant uses a new proprietary solvent developed by the company Carbon Clean Solutions. The solvent is reportedly just slightly more efficient than those used conventionally, requiring a little less energy and smaller apparatus to run. The collected CO2 is used to create baking soda, and it claims that as much as 66,000 tons of the gas could be captured at the plant each year.
Its operators say that the marginal gain in …
