“…At present, the supercritical carbon dioxide (S-CO 2 ) Brayton cycle system, instead of the traditional steam Rankine cycle system, shows great potential in improving the photoelectric conversion efficiency of the system and reducing the power generation cost. S-CO 2 Brayton cycle power generation technology, with its significant technological and performance advantages, has considerable application potential in the utilization of ship flue gas waste heat, which is a critical way to improve the green level of ships and realize energy conservation and emission reduction in the shipping industry [1][2][3]. As one of the core components of the system, the S-CO 2 heat exchange precooler influences the system circulation efficiency.…”

The flow distribution in a printed circuit heat exchanger (PCHE) is of great theoretical and practical significance in the Brayton cycle power generation system. For the straight barrel inlet header PCHE, when S-CO2 flows in the PCHE, the structural types and working parameters of the inlet header and diversion zone may lead to differences in the flow distribution in each channel of the PCHE. This flow distribution difference affects the thermal hydraulic characteristics of the PCHE. A numerical simulation method was applied to explore the flow uniformity of the PCHE and the overall performance and analyze the influence of the type of straight barrel inlet header PCHE. Within each layer, the flow showed an uneven flow distribution, and the optimized inlet header was the tapered type. The results showed that when the taper angle varies from 6° to 9°, the flow distribution in each layer is relatively uniform. The comprehensive heat transfer performance of the straight-channel PCHE can be improved by 17.3–19.7%. Finally, the response surface and a genetic algorithm were combined to optimize the inlet header. The heat transfer performance of the optimized PCHE was improved by 19.7%.

Due to the rising concern of environmental problems, fuel cell hybrid power systems have been proposed to be an ideal substitution to diesel engines. However, the hybrid power system has brought many challenges, one of which is the power splitting among different power generation technologies. In this paper, a wavelet transform and fuzzy logic based energy management strategy is proposed for a fuel cell/battery/ultra-capacitor hybrid power cruiser considering their dynamic characteristics. The energy demand of the cruiser is decoupled into different frequencies by wavelet transform and distributed to different energy sources according to their dynamic characteristics. To ensure long-term reliable operation of the hybrid power system, fuzzy logic is proposed to keep the state of charges of the battery and ultracapacitor within safe range. The proposed energy management strategy is applied to a hybrid power cruiser in MATLAB/Simulink and two cases are studied considering different initial states of charge of the energy storage system. The results show that the proposed energy management strategy enables the fuel cell to supply about 50% of the high frequency power and reduce the peak power supplied by the fuel cell by 80% -100% when the initial state of charge of the ultra-capacitor is low, and the fuel cell supplies around 400% higher than the low peak power and 20% of the high peak power when the initial state of charge of the battery is low.

Due to the more stringent regulations on pollutant and greenhouse gas emissions in the maritime transport sector, solutions are being sought to reduce or avoid the emissions generated during the operation of ships. The onboard installation of hydrogen-fuelled fuel cells is a solution respectful with the environment and the marine ecosystem through which ships navigate. In this work, the design of a wellboat and its power plant based on fuel cells fed with hydrogen and hybridised with batteries is conducted, making it a zero-emissions ship that can navigate Emission Control Areas (ECAs). The fuel cells used are polymer electrolyte membrane fuel cells (PEMFCs), and the hydrogen they consume is stored in tanks pressurised at 35 MPa, grouping these tanks into three standard containers (Twenty-Foot Equivalent Units) installed on an exposed deck. The electrical and propulsion needs of the ship are covered by the installed power plant, providing an average power of 1266 kW and a peak power of 2624 kW, making it possible to avoid the emission of 10.8 t of CO2, 195 kg of NOx and 9 kg of SOx per 14 h mission.
