Summary: The study reveals that at lower scales (up to 4 years), the causal influence of economic growth on energy consumption is stronger, while at higher scales, the causal relationship from energy consumption to growth weakens. Bidirectional causality is strengthened at all frequency bands, but the impact of energy consumption on economic growth is observed only at specific frequencies.

Summary: This study investigates the threshold effect of GDP on the causality between GDP and energy consumption using panel data of 26 OECD countries. The findings reveal that the relationship between GDP and energy consumption is influenced by a GDP threshold. When GDP is below a certain threshold, there is a unidirectional causality from energy consumption to GDP. However, when GDP exceeds the threshold, there is no short-term causality but a long-term causality from GDP to energy consumption. This highlights the need for policymakers to implement energy conservation policies at certain levels of economic development and adjust energy policies accordingly during different periods of economic growth to foster sustainable development.

Summary: This research aims to demonstrate how much renewable hydrogen can be produced in a sub-Saharan African context (Cotonou, Benin) and includes both numerical and experimental validation. Results show a 19% efficiency for solar hydrogen production, with limitations on production rate including storage pressure and available electricity. Economic analysis indicates a levelized cost of hydrogen production from solar photovoltaic of about 1.09 euro/m³ under present conditions.

Summary: This paper investigates the characteristics of thermochemical energy storage (TCES) reactors at temperatures below 125°C at both microscopic and macroscopic levels. The study emphasizes the importance of reactor geometry and choice of reactive bed at the microscopic scale, as well as the use of powerful software for simulation at the macroscopic scale. The review also provides a schematic description of the analysis of TCES systems, and proposes a dashboard for open and closed TCES reactors simulation.

Summary: This study aims to determine the sorption isotherms of three tropical woods from Cameroon and assess the influence of wood structure on their sorption behavior. The equilibrium moisture contents were experimentally determined, and a strong correlation was found between anatomical parameters and moisture contents. The results showed differences in sorption behavior among different woods at different temperatures, highlighting the importance of specific research data on sorption behavior of Central African woods.

Summary: The aim of this study was to determine the moisture desorption isotherms and thermodynamic properties of Tali and Bilinga woods from Cameroon. The equilibrium moisture contents decreased with increasing temperature. The GAB model best described the desorption isotherms data. Anatomical and chemical analysis revealed the structure and properties of the woods. The positive thermodynamic properties indicated that desorption was non-spontaneous and that Tali required more energy than Bilinga.

Summary: This study demonstrates the use of grid-connected hybrid PV and biogas energy with a SMES-PHES storage system to improve the economic viability, reliability, and environmental impact of the energy system in a nation with frequent grid outages. Metaheuristic optimization techniques have been used to find the best size for the hybrid system based on evaluation parameters for financial stability, reliability, and GHG emissions. The outcomes show that NSWOA is superior to MOGWO and MOPSO in achieving the best optimum value of the predefined multi-objective function for NPC, LPSP, and GHG emissions.

Summary: Ethiopia has untapped potential as a solar energy resource due to its location near the equator. The country heavily relies on oil imports and faces insufficient rural electrification, leading to poverty and high operational costs. A feasibility study conducted in this work shows that a PV-battery priority grid tie system is more economically and environmentally viable compared to the existing diesel generator system.

Summary: The article focuses on the impact of mobile phone use while driving on the performance of petroleum product drivers in Cameroon. The study used a literature review and practical research to propose a hypothetico-deductive model. Through multivariate logistic regression analyses, it was found that making or receiving calls while driving significantly influences reckless driving situations, while reading and sending messages negatively affects drivers' performance. The type of phone used also affects the risk of accidents, with smartphone users being more likely to experience crash-like events compared to those using conventional phones. The article suggests the need for regular road safety campaigns, on-board cameras in trucks, rest areas, and defensive driving training for drivers.
