Can baking soda curb global warming?

Some scientists have proposed compressing carbon dioxide and sticking it in underground caves as a way to cut down on greenhouse gases. Joe David Jones wants to make baking soda out of it.

Jones, the founder and CEO of Skyonic, has come up with an industrial process called SkyMine that captures 90 percent of the carbon dioxide coming out of smoke stacks and mixes it with sodium hydroxide to make sodium bicarbonate, or baking soda. The energy required for the reaction to turn the chemicals into baking soda comes from the waste heat from the factory.

"It is cleaner than food-grade (baking soda)," he said.

The system also removes 97 percent of the heavy metals, as well as most of the sulfur and nitrogen compounds, Jones said.

Our feed chemical for the reaction to remove the carbon is sodium hydroxide, which is produced on site as a part of the SkyMine™ process. This reaction to produce sodium hydroxide also produces hydrogen and chlorine as byproducts. These can be sold to market at a profit, not only defraying the cost of CO2 removal, but even generating a profit for the SkyMine™ operators. These chemicals are also “green”; they are produced at low energy and without emitting CO2 (since the heat to drive the process is captured from the heat in the flue gas).
