SkyMine from Skyonic – Baking Soda from CO2

Can baking soda curb global warming? At least one company thinks the answer is yes.

Joe David 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.

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

Luminant, a utility formerly known as TXU, installed a pilot version of the system at its Big Brown Steam Electric Station in Fairfield, Texas, last year.

    Unfortunately, a lot of the existing solutions for sequestration involve large amounts of capital and risk. If you bury carbon dioxide underground, it could always leak out. Other ideas include pumping it into underground saline aquifers or porous rock formations.

    Because it’s a solid, storing baking soda is simply easier, and it allows greenhouse gas emitters to store a lot of carbon in one place. The stuff piles up: A 500-megawatt power plant will produce approximately 338,000 tons of carbon dioxide a year. Multiply that weight by 1.9 and you get the number of tons of baking soda that the plant will produce. Still, it can be sold, stored in containers, used for landfill or buried in abandoned mines.
