The crux of the concept is laid out schematically in Fig. 1 with numbers for an optimized case. The process is built around two storage tanks: the hot tank containing heat transfer fluid (HTF) at high temperature (T H T F m a x = 311 C) and the cold tank containing HTF at a lower temperature (T H T F m i n =211 C). ...
