First plant converting CO2 into baking soda started in India

A coal-fired power station recently started in the Indian city of Tuticorin converts the CO2 produced by the same plant into baking soda. State-of-the-art plants do have carbon capture schemes, which typically use amine, storing CO2 and preventing it from escaping into the atmosphere. Yet, the Tuticorin plant has a more advanced system, which converts CO2 into a chemical intermediate which, afterwards, can be used by other plants. The plant is reported to use a class of solvents more efficient than the conventional one and to capture approximately 66,000 tons of the gas pa. The plant runs in fact without State subsidies, being supported by the proceeds from the NaHCO3 sales. (Sources MIT Technology Review & The Guardian)
