ZHANG Xinqi;LI Jun;HUANG Xinnan;ZHENG Kai;[Purpose] In response to the severe environmental challenges posed by the shipping industry's reliance on fossil fuels, and in alignment with the International Maritime Organization's(IMO) net-zero emissions target by 2050, [Method] the shipping industry has introduced on-board carbon capture technology with immediate emission reduction efficiency. This technology has become a key transitional solution as it can bridge the "gap period" between traditional energy efficiency optimization and fuel substitution technologies. Ship-based carbon capture technology has emerged as a critical transitional solution to bridge the implementation gap between conventional energy efficiency optimizations and alternative fuel technologies, owing to its immediate emission reduction capabilities. This study systematically examines the adaptability of carbon capture systems in maritime applications, building upon the framework of land-based carbon capture, utilization, and storage(CCUS) technologies through comprehensive analysis of advancements in material systems and process engineering. [Result] It critically reviews global research progress encompassing the entire ship-based carbon capture, utilization, and sequestration chain, synthesizing key research foci and principal achievements. The investigation culminates in identifying prevailing commercialization barriers and operational challenges, [Conclusion] while proposing strategic directions for optimizing shipboard carbon capture systems in alignment with maritime decarbonization objectives.
Analysis on Adaptability Assessment and Development Pathways of New-Energy Inland River Vessels of China
LI Kun;XU Xiaojian;FAN Ailong;YIN Zhiqi;YAN Xinping;China Waterborne Transport Research Institute;[Purpose] To clarify the application boundaries and promotion directions of new-energy and clean-energy technologies, including liquefied natural gas(LNG), methanol, battery power, and hydrogen fuel, for inland vessels in China, the adaptability assessment and development pathways of new-energy and clean-energy inland vessels are investigated. [Method] Based on a systematic review of China's green shipping policies and the current development status of new-energy and clean-energy inland vessels, a multi-dimensional adaptability assessment framework is established, covering technology maturity, emission reduction potential, energy security, supporting infrastructure, economic performance, and the completeness of standards and regulations. Based on the framework, comparative analyses are conducted among different energy technology pathways. [Result] Based on the adaptability assessment results, proposes an overall strategy of prioritizing methanol and battery power for long-term development, using LNG as a transitional option, and promoting hydrogen energy through pilot and exploratory applications, as well as development pathways for new-energy and clean-energy inland vessels differentiated by application scenarios and regional conditions. [Conclusion] The findings provide valuable references for energy transition of inland vessels, large-scale deployment of new-energy and cleanenergy vessels, and the development of a green shipping system in China.
CFD Simulation Analysis of Wet Flue Gas Decarbonization for Ocean-Going Ships
QU Ziyi;LI Yaxiong;LONG Haipeng;SONG Pengfei;ZENG Lu;[Purpose] In order to study the influence of gas-liquid mass transfer characteristics in decarbonization towers under different operating conditions on decarbonization efficiency, [Method] the actual exhaust gas emission characteristics of ocean-going ships as the basis is adopted, a three-dimensional computational fluid dynamics(CFD) model coupling gas-liquid flow, heat and mass transfer, and chemical reactions is established using the Eulerian-Lagrangian method. A user-defined function(UDF) is employed to achieve a refined simulation of the CO2 absorption process. The system comprehensively examines the gas-liquid concentration gradient, heat and mass transfer, and CO2 absorption characteristics of NaOH solution and seawater-NaOH solution under varying NaOH volume fraction, CO2 volume concentrations, absorber flow rates, and inlet flue gas temperatures. [Result] Results indicate that within the NaOH volume fraction range of 0.5 mol/L～2.5 mol/L, the decarbonization rate significantly increases. The lower the CO2 volume concentration, the higher the decarbonation rate, resulting in a larger CO2 volume concentration gradient within the tower, with a maximum variation rate of 83.33%. Increased absorbent flow elevates the concentration of slurry droplets, enhances the local mass transfer driving force at the gas-liquid interface, intensifying the formation of localized vacuum conditions between gas and liquid phases, yielding a maximum decarbonization rate increase of 27.71 percentage points. Increasing the inlet flue gas temperature releases substantial latent heat of vaporization, which promoting CO2 absorption. Under identical operating conditions, seawater-NaOH solutions and NaOH solutions maintain comparable decarbonization efficiency and instantaneous CO2 absorption rates, demonstrating strong potential and promising application prospects. [Conclusion] The research findings provide theoretical guidance and data support for the optimization of decarbonization technology for ocean-going ships.
Overview of the Development of Green Propulsion Technologies for Marine Fishing Vessels in China
ZHANG Junmiao;XIAO Beibei;YANG Xinglin;[Purpose] To promote the green development of propulsion systems for marine fishing vessels in China, [Method] the power demands of different types of marine fishing vessels are summarized. On this basis, the compatibility of new energy and clean energy sources with various fishing vessels is analyzed. The new challenges posed by new energy and clean energy in terms of additional safety risks and personnel training are discussed. Furthermore, the impacts of industrial structure, infrastructure, and clean fuel supply chains on the green development of marine fishing vessels are examined. [Result] According to the above analysis, the reasons for the current lagging green development status of China's fishing vessels are summarized, and suggestions for future development are proposed. The green development of China's fishing vessels should not be limited to passively responding to external pressures, but should serve as a key direction for proactive industrial upgrading and transformation. The outcomes of green development extend beyond environmental protection. Vessels, personnel, infrastructure, and even the entire industrial chain will undergo upgrades and transformations during this process. The production capacity and efficiency of the fishing industry will achieve leapfrog progress. [Conclusion] The research results can provide references for the green development of propulsion systems for marine fishing vessels in China.
Fuzzy Control Energy Management Strategy of Fuel Cell Ship Based on Decision Tree Optimization
LI Jia;ZHANG Muyuan;ZHU Ziwen;[Purpose] In order to address the problems of the conventional fuzzy control caused by excessive reliance on empirical knowledge in energy management strategies for fuel cell ships, [Method] a fuzzy control strategy based on decision tree optimization is proposed. The topological structure of the hybrid electric propulsion system that consists of a fuel cell and a lithium battery is determined, and the full-voyage operating conditions of the electric propulsion ship are selected. Cluster analysis is then employed to divide the fuzzy subset rules using the offline global optimal energy allocation scheme determined by the Dynamic Programming algorithm. [Result] A decision tree is used to optimize the fuzzy controller rules, followed by simulation analysis and computational evaluation. Simulation results show that the fuzzy control energy management strategy optimized by the decision tree reduces hydrogen consumption by 10.75% compared to the unoptimized strategy, resulting in a consumption of 142.28 g. [Conclusion] The proportion of fuel cell operation within the high-efficiency range increases by 27.9%, enhancing both economic efficiency and operational stability while maintaining system responsiveness.
