Summary: In this paper, the effects of wind speed on hydrogen leak, diffusion, and explosion in different regions of a hydrogen refueling station are analyzed. The results show that wind speed has a distinctive effect on the probability of hydrogen fires in different regions. Low wind speeds can increase the size and probability of hydrogen explosions in certain areas, while high wind speeds may increase the risk of accidents in the near-ground region. Additionally, delayed ignition time is found to correlate with increased explosion intensity and the presence of multiple flame fronts.

Summary: In this study, the quantum chemical method was used to investigate the hydrogen storage behavior on Pt (n = 1-4) cluster decorated C48H16 sheet. The results showed that the Pt (n = 1-4) clusters were strongly bonded to the surface of C48H16 sheet, and the charge transfer from Pt (n = 1-4) to C48H16 created an empty orbital for hydrogen adsorption. Molecular hydrogen was initially adsorbed through Kubas interaction, and then dissociative hydrogen adsorption occurred. External electric fields could enhance or weaken the adsorption ability.

Summary: Household solid fuel use is detrimental to health and the environment. The Indian government's PMUY subsidy has successfully promoted the adoption of LPG by millions of households. However, there is limited understanding of the decision-making process to reduce solid fuel use after transitioning to cleaner fuels. This study found that factors such as household wealth, social status, education level, and the prevalence of LPG use in the village are positively associated with LPG consumption and the discontinuation of solid fuel use. On the other hand, factors such as distance to LPG refill delivery, household size, and the PMUY subsidy are negatively associated with the share of LPG use.

Summary: Economic costs are a major political obstacle to investing in climate change mitigation and adaptation measures. The method of financing plays a crucial role in determining public opposition to government green investments, with debt financing being less opposed than broad-based taxes. This study suggests that credit market tools, such as green bonds and debt for climate swaps, can be politically efficient in increasing support for green financing. Carbon taxes and wealth taxes are found to be the most preferred options.
