Design and optimization of hydrogen production by solid oxide electrolyzer with marine engine waste heat recovery and ORC cycle

Modeling and Optimization of Ship Waste Heat Utilization System Based on Genetic Algorithm and Sensing

“…Energy is closely related to our work, production and life, and our future living environment, which promotes the rotation of machines. e combination of machine and man has formed advanced productive forces, which have promoted the continuous development of human society [1]. Tang et al said that throughout the development history of human civilization, every major change of human civilization was accompanied by the improvement and replacement of energy [2].…”

Decision support methods for sustainable ship energy systems: A state-of-the-art review

“…Regarding the operational optimisation of the propulsion system, a variety of studies was presented focusing on complex ship power plants, including hybrid systems. The operation optimisation of a novel hybrid system with hydrogen production from a solid oxide electrolyser was introduced in [122], whereas the economic optimisation of an electric propulsion system operation was proposed in [123,124]. In addition, models for the load allocation optimisation were presented in [125,126].…”

A Machine Learning Framework With an Intelligent Algorithm for Predicting the Isentropic Efficiency of a Hydraulic Diaphragm Metering Pump in the Organic Rankine Cycle System

“…In theoretical analysis, the isentropic efficiency usually takes a fixed value that has not been verified by experiments. Table 1 briefly lists the selection of the isentropic efficiency of the pump (Mohammadzadeh Bina et al, 2017;Mateu-Royo et al, 2019;Shen et al, 2019;Wang and Fu, 2019;Altun and Kilic, 2020;Morais et al, 2020;Schifflechner et al, 2020;Jafary et al, 2021;Khoshgoftar Manesh et al, 2021;Wang et al, 2021). The experimental test showed that the diaphragm pump efficiency was 32% (Kosmadakis et al, 2016); the efficiency of the vane pump was 36.9% (Kim et al, 2017); the plunger pump efficiency was 33.6% (Chang et al, 2015).…”

“…Moreover, the current research on pumps is generally carried out on the test bench of the ORC system (Feng et al, 2019). Because the experimental test of the ORC system is generally carried out under a stable high- Wang et al (2021) 2021 Design and optimization of the ORC for marine engine waste heat recovery 80 Morais et al (2020) 2020 Economic, energetic, and exergetic analyses of a solar-biomass-ORC cooling cogeneration hybrid system 85 Altun and Kilic (2020) 2020 Thermodynamic evaluation of the ORC for geothermal power 80 Schifflechner et al (2020) 2020 Thermodynamic comparison of the supercritical CO 2 and ORC for geothermal combined heat and power generation 80 Wang and Fu (2019) 2019 Thermoeconomic analysis of the CCHP-ORC system 80 Shen et al (2019) 2019 Design and optimization of the ORC system 100 Mateu-Royo et al (2019) 2019 Multi-objective optimization of a high-temperature heat pump-ORC hybrid system 90 Mohammadzadeh Bina et al (2017) 2017 Thermoeconomic evaluation of the ORC for geothermal power 95…”
