Summary: The paper examines an integrated solar combined cycle system (ISCCS) utilizing solar energy for steam methane reforming and compares its overall efficiency with that of a system utilizing solar energy for steam generation in a steam turbine cycle. Utilizing solar energy for steam methane reforming increases the overall efficiency by 3.5%. If water used for steam methane reforming is condensed from the exhaust gases, the overall efficiency of ISCCS increases by 6.2% to 8.9% compared to the system where solar energy is used for steam generation in a steam turbine cycle. Sankey diagrams based on the energy balance were compiled. Utilizing solar energy for steam methane reforming increases the power share of a gas turbine cycle, with two-thirds in the gas turbine cycle and one-third in the steam turbine cycle.

Summary: This paper proposes a grey box model for fuel consumption prediction of wing-diesel hybrid vessels based on feature construction. By using both parallel and series grey box modeling methods and six machine learning algorithms, twelve combinations of prediction models are established. A feature construction method based on the aerodynamic performance of the wing and the energy relationship of the hybrid system is introduced. The best combination is obtained by considering the root mean square error, and it shows improved accuracy compared to the white box model. The proposed grey box model can accurately predict the daily fuel consumption of wing-diesel hybrid vessels, contributing to operational optimization and the greenization and decarbonization of the shipping industry.
