The primary goal of this project was to prepare designs for indirect-heated, oxy-combustion-based, coal-fired, supercritical carbon dioxide (sCO₂) power plants, to assess the potential cost and performance benefits that this marriage of technologies might offer when compared to more conventional, oxy / coal-fired steam-Rankine power plants. The oxy-combustion technologies under investigation in this project were atmospheric-pressure, oxy-pulverized coal (PC) cases as well as chemical looping combustion cases. In addition, a smaller-scale air-PC plant without CO₂ capture integrated with a sCO₂ power cycle was also designed and compared to a comparable steam-Rankine cycle baseline.
