Summary: Thermoelectric generators (TEGs) utilize temperature differences to produce electricity and have potential for various industrial applications. This study introduces an advanced technique that utilizes temperature gradients in water pipes to increase power generation, with efficient modulation of output power through flow control. The feasibility evaluation in residential settings shows that TEGs can generate 10.95 kWh of electricity per unit, and to achieve zero-energy buildings, 64.5 m2 of TEG deployment is required per unit given a zT value of 1.

Summary: The development of CO2 electrolysis using symmetric solid oxide electrolytic cells requires the identification of electrode materials with high catalytic activity and stability. In this study, a high entropy perovskite electrode material LPSSCFN was designed and synthesized, which exhibited higher stability and chemical compatibility in the CO2 atmosphere compared to SSFN. Symmetric cells with LPSSCFN-GDC electrode showed higher electrolytic current density and excellent long-term stability compared to those with SSFN-GDC electrode.

Summary: In response to the existing political environment and concerns about climate change, strict regulations on traditional propulsion systems reliant on fossil fuels have been imposed. This study evaluates the potential of substituting EGR dilution with a water injection system for full load operation on a conventional diesel engine and compares it with EGR. The results show that water injection significantly reduces boost pressure requirements while achieving similar engine efficiency and reducing NOx emissions by around 80%.

Summary: This study aimed to investigate the mechanism of microbial roles during anaerobic storage of forages for biogas production. The results showed that the use of yeast-contained inoculants increased biogas production in perennial sorghum. As the proportion of yeast in the inoculant increased, the content of organic acids significantly increased. Additionally, the equal application of yeast and lactic acid bacteria altered the relative abundance of microorganisms and inhibited the growth of some harmful fungi.

Summary: The addition of hydrogen to liquid methane gas engines is seen as a promising way to improve their performance. However, current studies are limited to a few operating points. In this study, the effects of hydrogen addition on emissions, combustion, and performance of a liquid methane gas engine are comprehensively investigated under all operating conditions. The results show that increasing the hydrogen energy share improves the brake thermal efficiency and reduces fuel consumption and emissions. However, it is important to control the proportion of hydrogen addition to avoid excessive nitrogen oxide emissions.
