Breakthrough technology turns coal plant CO2 into baking soda

When it comes to mitigating the impact of modern civilization on our planet’s environment, many scientists and engineers have been focused on ways to clean up excess carbon dioxide, which contributes to climate change. India-based company Carbon Clean Solutions is making headway in that area, with its unique method for turning CO2 into harmless baking powder. The method can be employed by coal-burning industries to reduce CO2 emissions and turn the waste into usable byproducts that do no harm.

Carbon Clean is putting its methods through the wringer at a coal-fired thermal power plant at the industrial port of Tuticorin in southern India. There, CO2 is captured from the boiler and used to make soda ash (sodium carbonate) which is the very same stuff housed in any baker’s pantry. Transforming the dangerous atmosphere-heating carbon emissions into harmless baking powder is no simple (or cheap) task, but Carbon Clean is pushing forward even so, and the firm is doing it without government subsidies.

The firm says this process can lock up 66,000 tons of CO2 each year from the Tuticorin plant, which is the equivalent of removing 12,674 cars from the road for the same time period or burning 6,751,435 gallons of gasoline.

While these efforts won’t be enough to turn coal into a sustainable industry, Carbon Clean’s technique could help fossil fuel industries greatly reduce their carbon footprints.

    Thanks Jeff for these regular posts. The latest about reusing C02 is heartening as I believe it will take technology more than changes in human behavior to get us out of the climate change challenges. I am saving that link btw to that web site to follow their news. Looks like a good addition to the news that comes from Think Progress. Also, enjoyed your walk in the woods in winter posted recently. Ever consider making Meanderthal T shirts? I’d by one.
