Through the fall of 2016, Dr. David Stone received a federal grant to further the development and commercialization of Ferrock by constructing a usable storage structure on the Tohono O’odham Nation just west of Tuscon, Arizona.  The project is set to prove that viable structures can be economically constructed using a majority of recycled materials and bond together using the carbon-negative iron-carbonation process patented by Dr. Stone.

 

As this project concludes, Ironkast will secure a financial and development partner with which commercial production parameters, mixtures, and use applications will be defined with the goal being to secure a commercial production contract license of the technology.

 

The following pictures show the grant demonstration structure through the various stages of construction to-date.
