“…It is also feasible to use the unit’s squandered energy by utilizing ACCs. − The most famous working fluids for single-stage ACCs are water/lithium bromide (LiBr/H 2 O) and ammonia/water (NH 3 /H 2 O) . In addition, much research has been conducted on the performance of ACCs using other working fluids such as ammonia/lithium nitrate (LiNO 3 /NH 3 ), lithium bromide + zinc bromide/methoxide (LiBr + ZnBr 2 /CH 3 O), and calcium chloride/water (H 2 O/CaCl 2 ). , There are studies on the use of this technology, especially in power plants, food industries, , and oil and gas industries. , In particular, some studies have been conducted for the indirect use of ACCs to improve cooling performance in the LNG industry. − Also, diffusion–absorption − and absorption–compression − refrigeration process cycles are used to provide refrigeration in integrated structures. Figure illustrates a schematic of multieffect ACCs used in integrated systems.…”

The main challenges of liquid hydrogen (H2) storage as one of the most promising techniques for large-scale transport and long-term storage include its high specific energy consumption (SEC), low exergy efficiency, high total expenses, and boil-off gas losses. This article reviews different approaches to improving H2 liquefaction methods, including the implementation of absorption cooling cycles (ACCs), ejector cooling units, liquid nitrogen/liquid natural gas (LNG)/liquid air cold energy recovery, cascade liquefaction processes, mixed refrigerant systems, integration with other structures, optimization algorithms, combined with renewable energy sources, and the pinch strategy. This review discusses the economic, safety, and environmental aspects of various improvement techniques for H2 liquefaction systems in more detail. Standards and codes for H2 liquefaction technologies are presented, and the current status and future potentials of H2 liquefaction processes are investigated. The cost-efficient H2 liquefaction systems are those with higher production rates (>100 tonne/day), higher efficiency (>40%), lower SEC (<6 kWh/kgLH2), and lower investment costs (1–2 $/kgLH2). Increasing the stages in the conversion of ortho- to para-H2 lowers the SEC and increases the investment costs. Moreover, using low-temperature waste heat from various industries and renewable energy in the ACC for precooling is significantly more efficient than electricity generation in power generation cycles to be utilized in H2 liquefaction cycles. In addition, the substitution of LNG cold recovery for the precooling cycle is associated with the lower SEC and cost compared to its combination with the precooling cycle.

Engineers and scientists are increasingly interested in clean energy options to replace fossil fuels in response to rising environmental concerns and dwindling fossil fuel resources. There has been an increase in the installation of renewable energy resources, and at the same time, conventional energy conversion systems have improved in efficiency. in this paper, several multi-generation systems based on geothermal energy are modeled, assessed, and optimized with an organic Rankine cycle and proton-exchange membrane electrolyzer subsystem in five different arrangements. Based on the results, the evaporator mass flow rate and inlet temperature, turbine efficiency, and inlet temperature are the most influential parameters on system outputs, namely, net output work, hydrogen production, energy efficiency, and cost rate. In this case study, the city of Zanjan (Iran) is selected for a case study, and the results of system energy efficiency for changes in ambient temperature are examined during the four seasons of the year. To determine the optimal values of the objective functions, energy efficiency, and cost rate, NSGA-II multi-objective genetic algorithm is employed, and a Pareto chart is derived as a result. A system's irreversibility and performance are gauged by energy and exergy analyses. At the optimum state, the best configuration yields an energy efficiency and cost rate of 0.65% and 17.40 $/h, respectively.
