“…It is important to note that the Stirling engines not only generate higher work, but also operate with low noise. They also produce constant power output leading to wide potential applications [25] from producing electricity with wide variety of system configurations to utilizing in regasification of liquefied natural gas. Since they produce more electricity using cold energy than using waste heat potentials at the same temperature difference for the system, Dong et al…”

 A novel cogeneration plant including Stirling engine to produce water and hydrogen. A dynamic RO model including recovery turbine for different permeate flow rate. About 8% reduction in exergy destruction in the system using ideal Stirling engine. More electrical power production, higher than both LNG and CO 2 power cycle. Electrolyzer-based ZLD approach by employing electrolyzer beside RO desalination. ACCEPTED MANUSCRIPT AbstractThis study attempts to go beyond the conventional framework of the integrated solar transcritical CO 2 power cycle works, aimed at further utilization of available exergy as much as possible. This paper proposed a novel system for hydrogen and fresh water production in which a Stirling engine used instead of a condenser, for the places with abundant access to solar radiation and sea, and least to freshwater sources. This proposal leads to further utilization of streams' exergy through the system instead of wasting to the environment, and further power production by the engine followed by the higher products. The electrolyzer employed beside Reverse Osmosis (RO) desalination system, and takes full advantages of highly concentrated brine stream of desalination, eliminating the wastewater rejection through proposed system leading to attaining a near-ZLD approach in fresh water and hydrogen production. This reduces the adverse impacts of desalination's wastewater on the environment. A thermodynamic and exergy analysis is carried out to compare the superiority of this study and investigate the effect of some key parameters on the overall performance of the system as well. The results showed that replacing the condenser by a Stirling engine reduces the exergy destruction through heat transfer from CO 2 to an LNG unit. Exergy destruction was reduced from 16.7% to 8.8% for the above configuration for an ideal Stirling engine that exploits it to produce extra power which its minimum is at least 9 kW and 15 kW higher than CO 2 and LNG power productions.Moreover, Entering RO brine stream, wasting 2.58 kW exergy, to the electrolyzer leads toNaClO and H 2 production besides removing brine stream. In a power plant, sodium hypochlorite is used for disinfection of cooling systems and hydrogen can be used as a source of energy in fuel cells. An examination of some thermodynamic factors showed that higher ACCEPTED MANUSCRIPT 2 CO 2 turbine inlet pressure has an optimum value in producing fresh water and hydrogen, while the higher CO 2 turbine inlet temperature slightly reduces the productions rate. The more recovery ratio also causes a sharp reduction in hydrogen production, whereas it has an optimum amount of fresh water production at recovery ratio equals to 0.47.

“…Different thermodynamic systems like those based on Stirling cycle and Kalina cycle have been proposed, but in general those can be considered only preliminary studies and non-commercial solutions, as argued in Refs. [4,17]. Considering the important handling capacity of typical regasification stations, olften of the order of magnitude of 50e100 kg/s of natural gas, the potential for practical applications of the LNG cold energy for electricity generation should be further explored.…”

Liquefied natural gas (LNG) needs to be gasified before supplied to the users, and considerable amount of cold energy, about 830 kJ/kg, will be released during this process. Recovery of LNG cold energy bears significance of energy-saving and environmental protection. Among the many ways of using LNG cold energy, power generation is the most effective and suitable one for large-scale applications. Many novel power generation cycles have been designed for utilizing LNG cold energy so far. This paper reviews the recent researches on LNG cold energy utilization in power generation, and discusses 15 novel power generation cycles utilizing LNG cold energy.
