Low temperature sensible PTES with Kalina cycles

Techno-economic analysis of recuperated Joule-Brayton pumped thermal energy storage

“…PTES systems based on a variety of other thermodynamic cycles have been studied, including Rankine [27], trans-critical [28] and Kalina cycles [29], and a combinedcycle PTES-LAES arrangement that obviates the need for the so-called 'cold box' of LAES systems [30]. A review of these and other concepts is provided in Ref.…”
