Carbonfree Chemicals’ Plant

Located in San Antonio, Texas, Carbonfree Chemicals is expected to capture 75,000 tons annually of otherwise-emitted COfrom the coal-fired Capitol Aggregates Cement plant, and offset another 225,000 tons of annual US CO2 emissions by shipping CO2-negative chemicals to market and displacing CO2-intensive products. Our process also removes mercury, metals, sulfur dioxide, nitrogen oxides and particulate – and returns clean air and clean water.

 

Carbonfree Chemicals produces commercially saleable products of hydrochloric acid, caustic soda, baking soda (sodium bicarbonate) and bleach, which can be sold through chemical off-take contracts, and generate annual revenue even without an active CO2 credit market.

 

The SkyMine® process requires 30% less energy use to remove CO2 than the more common amine-based CO2 capture technology, which led to the US Department of Energy awards (2009-2010) of $28 million to develop this first commercial CO2-beneficial reuse SkyMine® commercial project. It was the largest grant of six carbon-reuse projects funded through the American Recovery and Reinvestment Act and the only one completed. More than 250 jobs were created during design and construction of the plant. During operation, there are permanent jobs at the plant and another 200+ permanent jobs in the local economy. Of the permanent on-site positions, approximately 1/3rd are engineers, 1/3rd operational technicians, and 1/3rd a combination of professional management and engineers—high-paying technical jobs.
