Our mission

We only have one planet, one atmosphere, and CarbonFree is driven by the passion to be part of the global journey to net-zero.

What We Do

CarbonFree has developed patented technologies that capture CO2 from stationary point source emitters and transform them into carbon-negative chemicals. 

Imagine if all industrial manufacturing plants could reduce their CO2 emissions and create green products.

SkyCycle and SkyMine® create sodium bicarbonate (baking soda), precipitated calcium carbonate (PCC), and hydrochloric acid.

CarbonFree’s modular and scalable technology can make this a reality, providing an on-site solution without the need of costly infrastructure to transport and store CO2

CarbonFree is ready to act now with its existing SkyMine facility in San Antonio, Texas and it’s first SkyCyle plant being deployed in 2022.
