CarbonFree

CarbonFree offers a modularized and scalable on-site carbon capture solution, SkyCycle, which eliminates the need for costly infrastructure to transport and store carbon dioxide (CO2). CarbonFree’s patented technology transforms CO2 captured from industrial flue stacks into carbon-negative chemicals such as sodium bicarbonate (baking soda), calcium carbonate (limestone), and hydrochloric acid.

Since 2016, CarbonFree has operated a non-modular carbon capture and mineralization facility in Texas called SkyMine, which captures around 50,000 tons of CO2 from cement flue gas and transforms it into baking soda. The first SkyCycle plant is expected to be deployed in 2022.

Key customers and partnerships 

In May 2021, CarbonFree partnered with TETRA Technologies, a global leader in commercial applications of calcium chloride, to advance commercializing SkyCycle. In July 2021, the company joined forces with BayoTech, a low-carbon hydrogen supplier, to deploy a pilot hydrogen production facility backed by carbon capture technologies. In the same month, CarbonFree contracted Fluor to install its technology at industrial plants. In October 2021,CarbonFree signed an MOU with Hitachi Zosen Inova to jointly develop technologies for separating and mineralizing CO2 from energy from waste plants (EfW) using the SkyCycle technology. 

In February 2023, CarbonFree collaborated with bp to identify and pursue potential development projects for its carbon capture technology. In March 2023, the company signed an MoU with US Steel to capture 50,000 tons CO2 emissions annually from the latter’s Gary Works manufacturing plant using CarbonFree’s SkyCycle technology.
