Successful Prototype to Turn CO2 into Stone


Blusky has just tested a small-scale version of its carbon mineralization machine – the Medusa. This machine takes in carbon dioxide and waste materials and converts it into limestone, securing the carbon dioxide for millions of years.

Blusky is working on further prototypes to make design improvements before building a large-scale system. This system will be attached to the Vulcan Pyrolysis system to increase the amount of carbon captured.

Pyrolysis, the act of heating in the absence of oxygen, is how Blusky converts wood from local town dumps into biochar, a carbon-negative soil additive.

The process also produces a gas stream called wood gas that can be burned – this how Blusky’s machine is self-sustaining, by producing enough wood gas to power the pyrolysis process.

This combusted gas becomes carbon dioxide, which is currently released into the atmosphere as a carbon-neutral emission. But by adding a Medusa system, this CO2 will also be captured and will greatly increase the outputs of Blusky’s pilot facility.
