Summary: This paper provides a techno-economic and environmental overview of H2 production technologies. Reforming of fossil fuels is still considered as the backbone of large-scale H2 production, while renewable hydrogen has advanced technologically but is expensive. A viable scenario is replacing fossil fuels with solar hydrogen production or biomass gasification, and integrating fuel cells with hydrogen production units for desired results.

Summary: This study investigates the requirements in geometrical design, electrode material, and operation parameter to achieve significantly improved fuel utilization under high flow rates in microfluidic fuel cells. It is found that simply increasing the electrode width or length cannot bring satisfactory fuel utilization, but optimizing the electrode aspect ratio could simultaneously enhance fuel utilization and current density. Developing advanced electrode material, particularly increasing the specific surface area, is shown to be more promising than geometrical optimization in improving fuel utilization in high flow rate systems where there is a mass transfer limitation.

Summary: A new energy storage system utilizing electrically rechargeable liquid fuels has been proposed. A model for a liquid e-fuel cell was developed to study the effects of operation variables and design parameters on cell performance. Increasing e-fuel concentration, sulfuric acid concentration, and flow rate improves cell performance, while membrane thickness degrades performance.

Summary: The study investigated the impact of air temperature on the penetration and mixing of liquid hydrocarbon fuel injected into supersonic airflows. The experiments involved supplying supersonic air of Mach 1.8 with temperatures ranging from 373 to 673 K to the test section. Using a laser sheet imaging system and Mie scattering, the research examined the characteristics of the fuel plume, fuel/air mixing process, and fuel evaporation. It was found that as the air temperature increased, the Mie scattering signal weakened due to enhanced fuel-air mixing and evaporation downstream of the injection point. At an air temperature of 673 K, most of the fuel evaporated before reaching the test section outlet.

Summary: The effect of supersonic air temperature on the mixing characteristics of liquid hydrocarbon fuel injected into three different supersonic airflows was numerically investigated. The study used ANSYS Fluent to solve compressible Reynolds-averaged Navier-Stokes equations and species conservation equations for two-phase flow simulations. The results showed that higher air temperature led to stronger streamwise vortices downstream of the pylon and increased evaporation of the fuel, resulting in higher mixing efficiency. The total pressure loss slightly decreased with increasing temperature due to droplet evaporation.

Summary: Blending oils from fast pyrolysis and hydrothermal liquefaction processes is important in biofuel production to adjust their composition and properties. This study evaluated the viscosity-temperature relationship of these oils and tested the predictive performance of selected mixing rules. The results showed that the viscosity-temperature relationship of these oils can be described using the MacCoull relationship, and the mixing rule by Miadonye et al. provided the best viscosity estimation.

Summary: This paper investigates the use of Klippen climate classification as a substitute for climatic measurements in neural network models for solar radiation. The study finds that when all data types are processed together, the impact of Klippen climate sub-classification on model performance is limited. However, if data are pre-classified according to climate type, significant improvements in model precision can be achieved.
