“…The distillation column is also commonly used in ammoniawater power cycles. [33][34][35][36][37][38] The inlets and outlets are tabulated in Table 5, and the detailed schematics of such a cycle can be referred to in Supporting Information. The ammonia-water solution is not necessarily purified to be near pure ammonia in power cycles; [9] therefore, the REC is no longer needed under the specified working condition, as can be seen from Figure 18a.…”

In this study, a comprehensive method to optimize distillation columns in ammonia–water absorption refrigeration, power, and cogeneration cycles is introduced. The novelty of this work lies in a comprehensive analysis of the distillation column's thermal performance and the introduction of a new design framework that maximizes heat integration. Key findings include the critical role of the solution heat exchanger, especially at lower generation and evaporation temperatures. Using a saturated liquid or two‐phase feed can achieve up to 80% efficiency at a feed composition of 0.3. Moreover, in the results, the substantial potential for improving the coefficient of performance (COP) through strategic design is highlighted. Notably, minimizing the pinch point temperature difference to 0 °C can boost the COP by 6%, while optimal feed placement can increase it by 9%. Incorporating feed preconditioning and side exchangers can lead to a 22% COP enhancement, indicating the significance of heat integration to the distillation column. In this study, a graphic guideline for selecting cycles that can achieve a minimum of 10% COP improvement without introducing unnecessary complexity is delivered and it suggests that distillation columns can be simplified by using a combination of separators, heaters, and coolers in certain cases.

“…Apart from the use of ORC or KC individually for power generation, Nabat et al [127,153] studied a combined ORC and KC system with TEG for power generation. For the ORC-TEG hybridization [127], both electrical power and hot water could be produced through a cascaded arrangement of ORC and TEG, to fully utilize the excess heat, leading to an improved system RTE and exergy efficiency to 61.1% and 52.8%, respectively, 6.59% and 3.28% higher than systems without the excess heat utilization.…”

“…A payback period of 3.91 years was shown, together with a final profit of $18.6 million. With a KC-TEG hybridization [153], the RTE was shown to be increased to 61.6%, with a payback period of 3.5 years and a total profit of $26.3 million for a 30 year operation if an optimal charging pressure of 150.9 bar and a discharging pressure of 84.4 bar were used. The combined LAES-TEG system was investigated by Liu et al [154] as well, their techno-economic analysis suggested an optimal hot water outlet temperature of 60 • C-80 • C, an overall efficiency increase of 1.7%, and a payback period as low as three years.…”

Liquid air energy storage (LAES) uses air as both the storage medium and working fluid, it falls into the broad category of thermo-mechanical energy storage technologies. Such a technology offers several advantages including high energy density and scalability, cost-competitiveness and non-geographical constraints, and hence has attracted a growing interest in recent years. As a result, several reviews have been published on the topic. However, these reviews covered little in the following aspects of LAES: dynamic simulation and optimisation, key components for LAES, LAES applications through integration, and unified economic model and cost models for LAES. This article provides a comprehensive review on the LAES technology and fills the above gaps. Apart from applications in electrical grids such as peak-shaving, load shifting, and dealing with intermittency of renewable generation, the review also shows a diverse range of other LAES applications through integration, including waste heat and cold energy recovery and utilisation, multi-energy-vector service provision, and sector coupling for chemical production and carbon capture. The review also led to the recommendation of several areas of LAES for future research and development, including dynamic characteristics of whole LAES system integrated with renewables and end users; thermo-economic and dynamic optimization of stand-alone LAES and integrated systems; and experimental study on commercial systems.
