Project Description

RRTC, Inc. and Rutgers University are developing a new solid state approach for carbon dioxide (CO2) capture, storage, and supply (CCSS) enabled by the combination of two technologies for low-energy processing of materials invented at Rutgers: (1) low-temperature solidification (LTS) for CO2 adsorption, and (2) hydrothermal vapor synthesis (HVS) for CO2 release from metal silicates. The CCSS process involves the use of a carbonation chamber to capture CO2 from flue gas and form a solid carbonate-bonded composite monolith brick (CaSiO3 [solid] + CO2 [gas] → CaCO3 [solid] + SiO2 [solid]), which can then be transported to a CO2 consumer and placed in an HVS reactor for release of CO2 (CaCO3 [solid] + SiO2 [solid] → CaSiO3 [solid] + CO2 [gas]). Once the brick is depleted of CO2 and converted back into CaSiO3, the material can be either recycled as carbonate cement or sent back to a power plant to capture more CO2. Together, the two technologies provide cyclability for capture and release of CO2, enabling transport of CO2 in solid form, which is less costly and allows more throughput than traditional storage forms such as dry ice and liquid CO2. In Phase I, RRTC will investigate the ability of CaSiO3 to capture CO2 directly from flue gas and release the CO2, as well as the ability to exhibit cyclability. The team will design and assemble a bench-scale apparatus for testing LTS carbonation with simulated flue gas. A high-level life cycle analysis will be performed to determine feasibility and costs for scale-up of the process.

Project Benefits

The CCSS process provides a low-cost, energy-efficient method for the management of captured CO2, enabling more widespread valuable use of CO2 in consumer products; reduces CO2 emissions from power plants; and makes progress toward reducing the net cost of CO2 capture to less than $10/tonne.
