ADDITIONAL PROJECT SELECTIONS FOR FOA 2614: CARBON MANAGEMENT
AREA OF INTEREST (AOI)-1 – CARBON CONVERSION TECHNOLOGY: IMPROVING ENERGY SYSTEMS FOR CURING CONCRETE
Biomass Ash Valorization by CO2 Capture for Nano-size Amorphous Calcium Carbonate Production and Use in Lower Carbon Footprint Cement — Calcify LLC (Fairfield, Connecticut) plans to develop a 20 kilogram (kg) per day prototype process utilizing biomass ash and desalination brines for the capture of carbon dioxide (CO2) yielding stabilized, amorphous calcium carbonate (ACC). The project team will demonstrate that stabilized ACC-containing cement has superior properties to ordinary Portland Cement and a lower carbon footprint. The team proposes to co-locate this process with a biomass combustion power plant and near a source of desalination brine. The biomass ash will be leached to recover its alkalinity, and the ash will then be used to capture CO2 from the flue gas for conversion to selective mineral carbonates.

Low-cost, High Yield and Scalable CO2 Mineralization to Invent Novel Carbon-negative Concrete — C-Crete Technologies, LLC (San Leandro, California) intends to demonstrate the feasibility of converting greater than 10 kg per day of CO2 to a special formulation of high-performance concrete that rivals or outperforms Portland Cement concrete while mineralizing net CO2. The concrete is intended to be a fast-curing and carbon-negative product with high strength and toughness that uses low manufacturing energy. The product is also intended to have access to a consistent source of alkalinity, adaptability to several waste streams, and application to both the precast and cast-in-place concrete markets as well as to diluted CO2 gas, including point sources and direct air capture. There is also no concern regarding low pH and steel rebar corrosion in concrete.

Integrated and Sustainable Pathways for CO2 Capture and Mineralization with Inherent Recovery of High Value Metals (INSPIRE) — Cornell University (Ithaca, New York) plans to advance a transformative energy- and atom-efficient technology for the co-recovery of calcium and magnesium carbonate, high-value energy critical metals (including nickel, cobalt and iron), and aluminum- and iron-rich products from alkaline industrial residues generated during secondary aluminum manufacturing and iron and steel making through integrated CO2 capture and conversion by using regenerable CO2 capture solvents.

Converting CO2 and Alkaline Solid Wastes into Carbon-Negative Supplementary Cementitious Materials for Co-decarbonization of Multiple Sectors — University of Missouri (Rolla, Missouri) plans to partner with Lawrence Livermore National Laboratory to use CO2 to process alkaline solid wastes, yielding carbon-negative supplementary cementitious materials (SCMs) to address the severe shortage of SCMs in construction and co-decarbonize multiple industrial sectors. The technology is readily adaptable to various CO2 sources (either low-concentration point sources like flue gases or captured CO2) and a broad range of negative-to-low-value solid wastes.
