Summary: The study reviewed literature on the energy efficiency of biomass-based Fischer-Tropsch plants, highlighting the limited number of techno-economic assessments due to the early stage of Bio-FT technology development. Plant design features for high conversion efficiency and low production costs include feeding biomass at low moisture content, pressurized gasifiers, and using efficient FT catalysts. Despite no correlation between overall efficiency and biofuel production cost, a moderate correlation was found between biomass-to-fuel efficiency and production cost.

Summary: Established biofuel examples show the potential for sustainable ways to reduce reliance on fossil fuels and mitigate negative effects. The biomass-to-liquid (BtL) route, particularly the Fischer-Tropsch (FT) process, offers a pathway for converting biomass into liquid biofuels. However, technical challenges and high costs still hinder commercial applications. This review synthesizes information on impurities generation and removal techniques in the gasification integrated into the Fischer-Tropsch process (G-FT), proposing a flexible gas cleaning sequence.

Summary: The production of Jet Biofuel is seen as a promising strategy to reduce the carbon footprint of the aviation sector, but competitive production costs and sustainability remain challenging. Jatropha curcas has emerged as a promising feedstock for Jet Biofuel production due to its non-edible nature and ability to grow in non-arable lands. Through an integrated pathway, this study shows promising results in converting 49% of Jatropha fruit into liquid fuels with a Jet Biofuel selectivity of 65%, achieving a minimum selling price of 0.445 $/kg below the market price of conventional Jet-A fuel.

Summary: The present study assessed three strategies to improve the economic feasibility of sustainable aviation fuel (SAF) production through gasification and Fischer-Tropsch synthesis (GFT) of lignocellulosic biomass feedstocks in Biomass-to-Liquids (BtL) plants. These strategies include integration with sugarcane ethanol production, use of economic incentives by the carbon credits market, and decentralization of the production chain with fast pyrolysis (FP) units. Process simulation coupled with techno-economic assessment (TEA) and life cycle assessment (LCA) were used to analyze these strategies. The study found that carbon credits commercialization alone is not sufficient for standalone GFT scenario, but integrating SAF production with 1G mill can significantly decrease production costs and achieve CO2 emissions reductions.

Summary: The increase in global population and industrialization has led to a significant rise in biogenic wastes. These wastes have the potential to be a valuable source of energy as an alternative to nonrenewable fossil fuels. Thermochemical technologies offer effective solutions for converting waste biomass into biofuels and valuable biochemicals. However, non-catalytic thermochemical conversion technologies face challenges such as low yields, undesired byproducts, and higher levels of heteroatoms that impact the quality of the final fuel products. This review article explores innovative catalytic approaches to address these challenges and evaluates the impact of catalysts on the production of biofuels and biochemicals through various thermochemical conversion technologies.

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.

Summary: Demand-side management is crucial to smart energy systems. This paper proposes a data-driven approach to understand the relationship between energy consumption patterns and household characteristics for better DSM services. The proposed method uses a clustering algorithm to generate optimal customer groups for DSM and a deep learning model for training. The model can predict the possibility of DSM membership for a given household. The results demonstrate the usefulness of weekly energy consumption data and household socio-demographic information for distinguishing consumer groups and the potential for targeted DSM strategies.
