Technology Development and Assessment for Supercritical Carbon Dioxide (SCO2) Based Power Cycles

archived

Power cycles based on a supercritical carbon dioxide, SCO2, working fluid have the potential for higher thermal efficiencies and a lower capital cost when compared to state of the art steam-based power cycles. The cost and performance of recuperators are currently seen as a significant barrier to the full-scale demonstration and economic viability of SCO2 power cycle technology. The purpose of this FOA is to seek applications for the development of high temperature recuperator technologies that are capable of handling the SCO2 RCBC system requirements while also maintaining a cost effectiveness required for commercial adaptation. Modular concepts and or strategies that are capable of scalability to address the wide variation in size, capacity and temperature anticipated for the varied applications are of particular interest. Responsive applications will provide a plan for focused research and development of innovative designs, materials and manufacturi ng methods to produce scalable, cost- effective recuperators suitable for deployment in large-scale SCO2 power cycle applications.
