Product Description
The task was to identify from public literature possible systems for evaluation based on the following high quality ( T>500 oC) heat sources: coal PFBC , Nuclear, Solar Thermal, and waste heat. Objectives included outlining how the heat source is currently or proposed to be used in a process and what information is available. All of the sCO2 cycles considered used indirect (closed) sCO2 cycles and direct cycles were not in the study scope. Concluding remarks pointed out that fossil-fuel-based heat sources are a promisig source for usage in sCO2 cycles. That solar sources are dependent on a thermal energy storage medium (e.g. molten salt) and this could lead to operation at lower temperatures then desirable to obtain high efficiencies. Other heat sources briefly explored were fuel cells, waste heat and current nuclear reactors.
