Summary: New alternative routes to traditional Fischer-Tropsch Synthesis (FTS) must be established to achieve a more efficient process in terms of energy and sustainability. Solar photocatalytic-assisted FTS is a promising new approach for obtaining fuels from renewable resources. Metal-doped TiO2 catalysts show enhanced photocatalytic activity under solar radiation, lowering the band gap and increasing the methanation activity, as well as promoting the production of ethanol.

Summary: Adding hydrogen energy to the biomass-to-liquid (BtL) process can significantly increase carbon efficiency. The energy efficiency of the electrolyzer is more important than the capital cost, and adding renewable energy to the gasifier is always beneficial. The operating costs of the electrolysis unit account for a significant portion of the total costs.

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.
