Cryogenic Carbon Capture™ Technoeconomic Analysis

Skid-Scale Cryogenic Carbon Capture

The Cryogenic Carbon CaptureTM (CCC) process is a retrofit, post-combustion technology that desublimates CO2 in the flue gas, separates the resulting solid from the remaining light gases, pressurizes the solid CO2, melts the CO2 and warms the light gas, and completes the CO2 pressurization with liquid CO2. This skid-scale CCC system has demonstrated successful carbon capture of 90–99% from simu...

Energy Storing Cryogenic Carbon Capture

The Cryogenic Carbon CaptureTM (CCC) process is a retrofit, post-combustion technology that desublimates CO2 in the flue gas and produces a separate liquid CO2 product. This project focuses on the energy-storing version of this process, CCC ESTM. During off-peak hours, CCC ESTM generates more refrigerant than is needed for the process, which is stored in an insulated vessel as a liquid at the l...

Effect of Cryogenic Carbon Capture (CCC) on Smart Power Grids

Ubiquity of Exciton Localization in Cryogenic Carbon Nanotubes

We present photoluminescence studies of individual semiconducting single-wall carbon nanotubes at room and cryogenic temperatures. From the analysis of spatial and spectral features of nanotube photoluminescence, we identify characteristic signatures of unintentional exciton localization. Moreover, we quantify the energy scale of exciton localization potentials as ranging from a few to a few te...

Optimal Control of the Carbon Isotopes Cryogenic Separation Process

The most important demand in an efficient carbon isotope separation is to keep the cryogenic distillation column parameters at their required set points, despite disturbances or uncertainties. One of the key parameters is the column temperature that has a direct influence on the carbon separation coefficient. The nonlinear model of the separation process considers the top and bottom column temp...
