Determinants of fossil fuel subsidies: Analysis of economic, environmental, and institutional factors using a dynamic panel data approach
One of the obstacles to sustainable development goals (SDGs) is fossil fuel subsidies (FFS), which have economic, environmental, and social impacts. In addition, it is important to identify the factors that determine FFS. Although FFS have declined in recent years, they remain at high levels.…

Surface modification and characterisation of LaNi5 metal hydride powders with Cu and Cu/Ag coatings
The low thermal conductivity of LaNi₅-based metal hydride powders limits efficient heat removal during hydrogen charging and discharging, thereby reducing overall system efficiency. This study examines the application of a Cu/Ag duplex coating on LaNi₅ metal hydride particles to minimize interparticle thermal resistance and improve…

Hydrogen carriage consideration from engineering and economic perspective for Konya/Türkiye
The paper has evaluated hydrogen transportation in Konya/Türkiye. The evaluation included km, population, consumption, and economic perspectives. Three points have been chosen for transportation consideration, which are pipelines, cryogenic tankers, and tube trailers, due to geographical limitations. The economic perspective includes both investment and operational…

Investigation of the effect of coating on hydrogen charge and thermal characteristics in LaNi5 based metal hydrides
The thermal and mass behavior of LaNi5 alloy, a metal hydride-based hydrogen storage material, modified with different surface coating types was investigated during the hydrogen storage process. Based on the experimentally measured thermal conductivity coefficients, four different sample groups were created: Sample 1 – uncoated…

The relationship between renewable energy consumption and health expenditures: The case of G-7 countries
This study examines the impact of renewable energy consumption, economic growth, and death rates on healthcare expenditures in G-7 countries over the 1992-2023 period using panel data analysis. Preliminary analyses indicate cross-sectional dependence and heterogeneity across countries. The Fourier LM unit root test reveals that…
