Abstract

Energy planning is a privileged scientific tool, enabling quantified analyses of the energy future of countries or regions of the world. These analyses provide a scientific basis for energy policies and implementation strategies. The Democratic Republic of Congo (DRC), despite its considerable hydroelectric potential, makes little use of its resources due to various challenges, leaving a large part of the population without access to electricity, which hampers community and economic development. This article analyzes the opportunities for developing the hydroelectric potential of the DRC up to 2050. Using OSeMOSYS (Open-Source Energy Modelling System), prospective modelling was carried out to assess the technical, economic and environmental impacts of an ambitious energy scenario centered on hydropower (Scenario HYDRO).  The study develops an energy modelling approach for the DRC, considering demand, supply and energy policies, based on reliable data and aimed at optimizing the use of resources, in particular hydroelectric potential. The results indicate a potential installed capacity of 23 GW by 2050, dominated by hydropower (83%). This scenario meets the growing needs of national electrification, with 70% of the energy designated for the residential sector. The study highlights a significant reduction in CO2 emissions, estimated at 1,229 Mt cumulative by 2050. However, achieving these targets will require around USD 100 billion in investment. The results provide a sound basis for the development of energy policies in the DRC that will promote universal access to sustainable energy, reduce carbon emissions, reduce pressure on forests and ensure energy security. The results of this study recommend massive investment in hydropower, standardization of the electricity sector and improved data collection to achieve universal electrification and significantly reduce CO2 emissions in the DRC by 2050.

Abstract

Alkaline Polymer Electrolyte Fuel Cells (APEFCs) have emerged as a promising candidate for clean energy production. Anion exchange membrane (AEM) is an essential element of alkaline polymer electrolyte fuel cells for its role in facilitating hydroxide ion conduction. The objective of this study is to investigate the effect of a glutaraldehyde-based crosslinker solution on the performance of anion exchange membranes (AEMs) fabricated using quaternary ammonium poly (vinyl alcohol) (QPVA) as the backbone polymer and polyquaternium-7 as the second polymer. The introduction of a glutaraldehyde-based crosslinking agent was purposed to enhance membrane stability and reduce excessive swelling. The study evaluates the impact of varying glutaraldehyde concentrations on membrane performance. FTIR analysis confirms the presence of key functional groups of QPVA, polyquaternium-7, and the crosslinking agent. SEM images reveal that the membranes demonstrate dense and homogeneous physical structure. The results show that water uptake, swelling degree, ion exchange capacity (IEC), and hydroxide conductivity are influenced by the concentration of the glutaraldehyde solution. The QP-GA-13 AEM exhibited the best overall performance, achieving the highest tensile strength of 31.1 MPa and the highest hydroxide ion conductivity of 4.15 mS cm⁻¹ at 70°C. In single-cell tests, this membrane delivered a maximum power density of 85 mW cm⁻² and a current density of 350 mA cm⁻² at 80°C under humidified oxygen conditions.

Abstract

This investigation focused on assessing the feasibility of biochar production through microwave pyrolysis of Dodonaea viscosa branches. It considered the role of various important parameters, such as the power levels, biomass particle sizes, and the duration of pyrolysis, on both the yield and the quality of the obtained biochar. The assessment was conducted within a 25-minute pyrolysis time frame. The study also looked at how the yield of biochar changed over time. The results showed that the maximum biochar yield was obtained under conditions where the biomass particles were large (2–2.5 mm) and the power levels low (130 W). However, the yield was reduced when the biomass particles (0.5–1 mm) under higher power (650 W) were used. It was found that the yield of particles 2–2.5 mm dropped from 82% for 5 minutes at 130 W to 49.8% for 25 minutes. Further research has examined the dynamics of power variation on biochar characteristics. Several types of analysis were used to find out the surface area and pore volume. These included energy dispersive X-ray spectrometry (EDX), scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectrophotometry (FTIR), and Brunauer-Emmett-Teller (BET) analysis. The EDX analysis showed an increment in carbon to 89.7%, accompanied by a decrease in oxygen percentage to 4.9% under higher power. The SEM scan showed a tremendous improvement in pore formation corresponding to higher power. The XRD test showed that biochar went from being crystalline to being amorphous when compared to the native Dodonaea viscosa branch. At 520 W for 25 minutes, the surface area increased from 3.034 m²/g to 21.634 m²/g, while the pore diameter increased from 2.653 nm to 13.215 nm, showing an improvement in pore density. The results realized that the biochar obtained from microwave pyrolysis of Dodonaea viscosa branches has certain characteristics that make it useful for several purposes, like electricity production, water and gas treatment, soil improvement, and carbon dioxide gas reduction.

Abstract

Optimization of chitosan-based gel electrolytes modified with conducting polymers and ionic liquids for dye-sensitized solar cells (DSSC) has been done to improve its electrochemical activity. The effects of iodide salts, 1-propyl-3-methylimidazolium iodide (PMII), and polyaniline incorporation on the electrochemical properties of chitosan-based electrolyte, as well as its performance as a quasi-solid electrolyte in DSSC, were systematically investigated. A study on the effect of different iodide salts on the electrochemical properties of the electrolyte was conducted by employing various iodide salts (lithium iodide, sodium iodide, potassium iodide, or cesium iodide). Electrolytes with various amounts of PMII and polyaniline were also prepared. X-ray diffraction (XRD) and Fourier transform-infrared (FTIR) analysis were conducted to study the effect of iodide salts, PMII, and polyaniline on the change in intermolecular interaction of the chitosan matrix. The ionic conductivity and the redox activity of the chitosan-based electrolyte were respectively evaluated using conductometry and cyclic voltammetry analysis. It is found that the larger cation size of the iodide salts and a higher amount of PMII resulted in both higher intensity of the redox peak current and conductivity of the electrolyte. Those two characteristics increase with the presence of polyaniline, but the low transparency of this polyaniline-based electrolyte lowers the solar cell’s efficiency. The highest performance DSSC utilizing a chitosan/KI-PMII based electrolyte resulted in a Voc of 0.402 V, Jsc of 0.335 mA/cm², fill factor (FF) of 0.432, and an overall power conversion efficiency (PCE) of 0.058%. This efficiency is approximately one-third that of the conventional liquid electrolyte-based DSSC. The optimized chitosan-based electrolyte offers promising performance in replacing the low-stability liquid electrolyte-based DSSC.

Abstract

The present study analyzes thermal and dynamic fields, heatlines visualization and entropy generation as well as flow energy, flow rate and heat transfer through a natural convection flow inside a top-open cavity receiver. For the case of a horizontal cavity, lower walls are heated at a uniform temperature while vertical walls are treated as adiabatic. The lattice Boltzmann method (LBM) is applied to solve governing equations of the problem. Effects of Rayleigh number (103 ≤ Ra ≤ 105), cavity orientation (0° ≤ θ ≤ 75) and cavity aspect ratio (1 ≤ A ≤ 1.75) on thermo-fluid characteristics of the flow are performed. It was found that current findings computed by LBM are in line with existing literature. Findings reveal that flow patterns and heat transfer are strongly affected by variations of Ra, θ and A. The rise of Ra leads to a change in the orientation of heatlines trajectories with a growth of the stratification degree of entropy generation within the horizontal square cavity. Additionally, an enhancement of the convective heat transfer is detected as increasing Ra accompanied with more energy absorbed by the flow and an intensification of the entrainment phenomenon of fresh air by thermal plumes. For Ra = 5×104, the optimization of heat transfer and total entropy generation demonstrate the existence of a critical angle of the square cavity receiver corresponding to the cavity orientation of θ = 45°.Increasingthe angle θ reduces the stratification degree of heatlines and entropy generation as well as the flow rate. The rise of the geometrical parameter A entrains an increase of thermal gradients with a deceleration of the flow circulation. A decrease of flow rate and convective heat transfer with the growth of the aspect ratio of a horizontal cavity is detected for Ra = 5×104.

Abstract

Maritime plays an important role in the national economy since a large number of goods in the world are transported by sea, although maritime transport is found to generate the largest greenhouse gas emission among transportation means. For maritime activities, the port is considered the key chain in logistics, thus, the transformation of ports into sustainable energy centres has emerged as a major need in the worldwide initiative to decarbonize marine activities. This research provides a comprehensive techno-economic evaluation of a Hybrid Renewable Energy System (HRES) for Thi Nai Port, Vietnam, utilizing HOMER Pro software. The suggested system seeks to eradicate dependence on fossil fuels by including solar photovoltaics, wind turbines, a biogas generator, and sophisticated battery storage, therefore providing operational robustness. Simulation outcomes demonstrate that an ideal configuration, consisting of a 6,175-kW photovoltaic array, a 500-kW biogas generator, and a 2,357-kW converter, results in a net present cost of 44.6 million USD and a levelized cost of energy of 0.394 USD/kWh. Renewable sources constitute 100% of the installed and operational capacity, with yearly carbon dioxide emissions diminished to a modest 1,286 kg. The research verifies that hybrid renewable solutions may provide competitive economic returns, with a payback period of eight to ten years, while delivering substantial environmental advantages. The study portrays Thi Nai Port as a scalable paradigm for green port transformation, offering a repeatable framework for other mid-sized ports in Southeast Asia pursuing sustainable energy solutions.

Abstract

This study examines the feasibility and optimization of hybrid hydro-solar-wind-hydrogen energy systems in Togo, focusing on seasonal variations and energy management. Data on solar radiation, wind speed, and hydropower were obtained from meteorological stations, satellite databases, and the Nangbéto station. The results of this study show that the energy management system at the Nangbéto dam could rely on hydrogen storage and a 2.75 MW fuel cell to balance seasonal fluctuations, while a ±3 MW battery would stabilize power output. During periods of high hydropower production, surplus energy could be converted into hydrogen to ensure a continuous supply during low-flow months. The flow fluctuates seasonally, ranging from 1.5–20 m³/s in dry months to over 120 m³/s in the wet season, affecting hydrogen production (5–25 kg/day). Electrolysis efficiency remains stable (65–85%) due to optimized management. The hydro-solar-wind hybrid system converts up to 20% of hydropower into hydrogen, with peak production in August (~1,700 kg/month). Selected sites over Togo, particularly Blitta and Alédjo, show potential for hydrogen infrastructure, with Blitta yielding the most hydrogen (532.15 kg annually) and Lomé the least (482.72 kg) due to differences in solar irradiance. The study highlights the role of energy storage, hybrid integration, and policy support to enhance Togo’s hydrogen production and long-term energy stability.

Abstract

In the study, researchers developed and characterized xylitol membraneless alkaline fuel cell catalysts—namely FeCo/C, AgFeCo/C, and Pd/C—for cathodes and anodes. The first part of our investigation details the catalysts' morphology and elemental composition. STEM, EDS, and EDS mapping confirmed that the catalysts exhibited a small, lumpy structure, with the alloy well-dispersed across the support material. The X-ray diffraction pattern for the cathode catalyst reveals that the spectral lines corresponding to the Ag metal peak at a 2θ maximum of 38.12 degrees exhibit a 111 pattern, suggesting the existence of Ag metal particles in a face-centered cubic (fcc) arrangement. Meanwhile, the metal peaks for Fe3O4 and Co3O4 appear at maximum 2θ positions of 35.45 and 30.09 degrees, respectively, displaying 311 and 220 patterns, which indicate the presence of Fe3O4 and Co3O4 particles with spinel cubic structures. In the case of the anode catalyst, the spectral line for the Pd metal peak at a 2θ maximum of 40.12 degrees shows a 111 pattern, confirming the presence of Pd metal particles with a face-centered cubic (fcc) structure. Second, to determine the electrocatalytic properties, cyclic voltammetry (CV) measurements were conducted with xylitol as the fuel, utilizing concentrations between 0.1 and 0.5 M in 0.1 M KOH. For the cathode-side FeCo/C and AgFeCo/C catalysts, oxidation resistance was observed, and the reduction reaction diminished with increasing xylitol concentration, attributed to interfering non-conductive hydrocarbons. Conversely, Pd/C catalysts exhibited remarkable catalytic performance, particularly at 0.1 M xylitol solution, where the oxidation peak current density reached a maximum of 0.9 mA·cm⁻² at -0.09 V. Finally, the researchers reported that the Pd/C-AgFeCo/C catalyst achieved the highest current density of 0.36 A·m⁻² and a maximum power density of 0.129 W·m⁻² for xylitol fuel cell applications.

Abstract

To spread the use of Wind H-Darrieus turbines to electricity generation in urban or rural environments is necessary to improve some of its main drawbacks such as: aerodynamic efficiency, self-starting capability and torque fluctuations. The aims of this study are to enhance the aerodynamic efficiency and self-starting capability of an H-Darrieus turbine through wind tunnel tests combined using a 3D numerical study using Computational Fluid Dynamics (CFD). The NREL S815 profile and four modified versions were evaluated, including one with a 19.2% increase in thickness and three chord-to-diameter ratios: ????/????=0.15, 0.20, and 0.225. These configurations were tested at wind speeds of 6 and 8 m/s. Static torque was measured experimentally, alongside numerical calculations of flow and pressure distribution. A significant correlation between chord length and turbine performance was observed. The ????/????=0.20 profile exhibited increases of up to 50.27% and 58.88% in static torque at 6 and 8 m/s, respectively. The static torque coefficient increased from 0.0063 in the original profile to 0.0447 in the C/D=0.20 profile, directly contributing to the improvement of self-starting capability. Although the ????/????=0.20 geometry showed improvements, the C/D=0.225 profile did not show additional performance gains, indicating that further increases in chord length do not improve turbine performance. The profile modified with a 19.2% increase in thickness ranked just below the ????/????=0.2 profile, exhibiting torque increases of 41% and 25.22% at 6 and 8 m/s, respectively. These findings confirm that chord-to-diameter ratio adjustments play a critical role in boosting torque generation in vertical-axis wind turbines.
