Abstract

Solar mini-grids present a viable solution for electrifying off-grid rural and remote areas. However, their implementation and long-term sustainability encounter several challenges in most developing countries, including Zambia. This study aims to identify the risks associated with solar mini-grids in Zambia and to explore effective mitigation strategies. By adopting ISO 31000 for risk management, the research develops a comprehensive Risk Management Framework tailored to the needs of solar mini-grid projects. An inductive approach is used to investigate the key risks affecting the faster adoption and deployment of solar mini-grids in Zambia, allowing for an in-depth exploration and understanding of complex phenomena. Expert interviews serve as the primary data collection method, providing detailed insights from individuals experienced in solar mini-grid projects in Zambia. The data gathered through these interviews is analyzed using MAXDQA software, a tool for qualitative data analysis. The findings reveal a lack of a standardized and comprehensive risk management framework, with organizations relying on isolated tools such as risk registers and assessment matrices, leading to inefficiencies and sustainability challenges. Key risks identified include funding difficulties, licensing issues, technology acceptability issues, energy affordability, and system design failures leading to technical issues. The study proposes several mitigation strategies, including diversifying funding sources, streamlining regulatory processes, implementing training programs, engaging local communities, and ensuring high-quality procurement. It is recommended that a comprehensive, integrated risk management framework be established, incorporating continuous risk monitoring throughout the project lifecycle. Additionally, the research highlights the importance of capacity-building initiatives, stakeholder engagement, sustainable business models, and post-project monitoring to ensure the long-term success and resilience of solar mini-grids in Zambia.

Abstract

The Alpine region of Europe, which covers several countries including France, Switzerland, Italy, Austria and Germany, is characterised by its complex geology and significant geothermal potential. This research investigates the geochemical characteristics of geothermal water in the Alpine region, focusing on understanding the origin, evolution, and potential applications of these geothermal resources. Through comprehensive hydrochemical and isotopic analyses, we have identified key geochemical signatures that distinguish the various geothermal systems in the region. The results show that these geothermal waters are mainly influenced by deep magmatic processes, extensive water-rock interactions, and mixing of meteoric and magmatic fluids. Elevated concentrations of elements such as sodium (Na), lithium (Li), and chloride (Cl), as well as different stable isotopes, provide insights into the thermal and geochemical environments of geothermal reservoirs. Based on isotopic analysis oxygen (δ¹⁸O) and hydrogen (δ²H), the most of the geothermal water in the Alpine mountain region of Europe is of meteoric origin (derived from meteoric waters). The isotopic composition can reveal the mixing between meteoric and magmatic water. Intermediate values between GMWL and magmatic water compositions indicate such mixing, helping to understand the fluid dynamics within geothermal systems. This research underlines the importance of integrating geochemical studies in the exploration and management of geothermal resources in tectonically active regions such as the Alps.

Abstract

Shallow groundwater and river water problems in each country are caused by various factors such as natural factors such as natural disasters, human activity factors such as waste pollution, and others. In this study, we analysed the hydrochemical characteristics of river water to determine the water quality of shallow groundwater and Kinokawa river in Wakayama region of Japan. Shallow groundwater and river water samples were taken along the Kinokawa river at a total of 86 points. The water samples were analysed using Inductively Coupled Plasma-Mass Spectrometry (ICP-MS). In this case, we investigated physicochemical parameters such as total dissolved solids which mainly depend on the concentration of major ions such as Ca, Mg, Na, K, Cl, Li, HCO3, NO3 and SO4 which are used to characterise river water quality. The results of this study show that the calculated values of SAR, PI, Na%, MH and RSC indicate good groundwater use for irrigation purposes. Comparison of geochemical data showed that more than 75% SAR, 94% PI, 80% %Na, and 97% MH indicated a good environmental condition category and the river water can be used for irrigation purposes. The water quality information presented in this paper will be useful for sustainable management of water resources in the study area.

Abstract

The Boron-Lithium-Chlorine (B-Li-Cl) trend line serves as a valuable geochemical tool for distinguishing the dominance of hydrothermal water and surface water in geothermal environments. In this study, we applied the B-Li-Cl trend line to analyze the geochemical characteristics of water samples from the Tengchong geothermal area in Southwestern China. Our results reveal distinct patterns that differentiate hydrothermal water from surface water, offering insights into the geochemical processes and interactions occurring in this region. The lower Cl/Li and Cl/B ratio values of meteoric water with a Cl concentration of less than10 (mg/L) indicate that mixing occurs not only when migrating upwards, but also inwards. The absence of a trend formed at a Cl concentration of less than10 (mg/L) proves that the Cl concentration can be diluted by mixing with meteoric water. Meanwhile, the concentrations of Li more than 100 (µg/L) and B more than 1 (mg/L) form a downward trend from magmatic water, while the concentration of B less than 1 (mg/L) has a downward trend from meteoric water. Both interpretations confirm that the behaviour of Lithium and Boron towards temperature changes has the same tendency, which can illustrate the origin of hydrothermal water formation.

Abstract

This study evaluates the effectiveness of the Induced Polarization (IP) method in identifying mineral presence within the Pacitan region through a detailed case study utilizing 2-dimensional (2D) interpretation of crossing lines. The Pacitan region, with its diverse geological structures, offers an ideal test site for assessing the IP method's capabilities in mineral exploration. By conducting extensive IP surveys and integrating the data with geological and geophysical information, distinct anomalies indicative of mineralization were identified. The results demonstrate that the IP method is highly effective in detecting subsurface minerals, providing a reliable tool for exploration. The 2D interpretation of crossing lines significantly improved the accuracy of anomaly detection and offered detailed insights into the spatial distribution of mineral deposits. Based on the IP survey results, a large resistivity anomaly is located at a distance of 40 metres from the starting point of measurement with a depth of 2-20 metres and a diameter of about 40 metres. Meanwhile, the chargeability anomaly is at a distance of 30 metres from the starting point with a depth of 4-24 metres and a diameter of about 30 metres. When observed from each analysis of line 1 and 2, the cross results can identify resistivity and chargeability anomalies very accurately. This research highlights the potential of the IP method as a non-invasive, cost-effective approach for mineral exploration, particularly in geologically complex regions like Pacitan. The findings underscore the method's utility in enhancing mineral prospecting efforts and contributing to more efficient exploration strategies.

Abstract

The global energy crisis and continued reliance on fossil fuels have intensified the search for sustainable alternative energy sources, particularly biomass-derived biofuels. One promising yet underutilized resource is the peel waste of Carica pubescens, a papaya variety indigenous to the Dieng Plateau. This study investigates the potential of Carica peel waste as a bioethanol feedstock through sulfuric acid (H₂SO₄) hydrolysis and fermentation using Saccharomyces cerevisiae. To optimize sugar yield, the concentration of H₂SO₄ was varied between 0.1 M and 0.8 M, while fermentation durations were set at 96, 120, 144, and 168 hours. Results indicated that hydrolysis with 0.8 M H₂SO₄ produced the highest sugar concentration (6.8%). The most effective fermentation period was 120 hours, yielding 64% bioethanol with a density of 0.8679 g/mL, a calorific value of 4,831 kcal/kg, a flame height of 14.6 cm, and a combustion temperature of 438°C. These findings demonstrate the viability of Carica peel waste as a valuable raw material for bioethanol production. Its high efficiency and favorable fuel properties highlight its potential for integration into local renewable energy initiatives, contributing to sustainable energy development. Further studies on large-scale implementation and process optimization are recommended to maximize its industrial application.

Abstract

Geothermal is a natural resource energy in the form of hot water or steam that forms in reservoirs within the earth through the heating of subsurface water by hot igneous rocks. Based on field surveys, the Sulili area shows characteristics of geothermal energy in the form of hot springs. The research aims to use the Na-K geothermometer to find out the temperature of the geothermal reservoir below the ground and the Na-K-Mg geothermometer to look into the type of fluid that is in the geothermal reservoir. The research employs the geochemical analysis method in conjunction with the Na-K geothermometer method. Reservoir subsurface temperature is estimated at EPU station 1 at 326.504°C, EPU station 2 at 473.369°C, and station EPU 3 at 456.508°C. According to the results, the hot springs at the three sites are chlorides with temperatures below ground that are part of the high-temperature geothermal system and are >225°C. The hot spring is in the immature water group. Based on the calculation, the Sulili Geothermal Field with an average reservoir temperature of 418°C is approximately 68.33 MWh. This is a simplified calculation, and actual energy output can vary based on several factors, including the specific characteristics of the geothermal reservoir and the efficiency of the power plant.

Abstract

During the rainy season, surface water can infiltrate and mix with groundwater, making it difficult to identify different groundwater sources. In addition, mixing of water from different sources over time can obscure the original characteristics of groundwater. Continuous monitoring equipment can be affected by seasonal weather conditions, leading to data gaps or inaccuracies. In this study, we used geochemical analyses such as alkalinity, major elements, hydrological modelling and long-term monitoring before, during and after the rainy season to understand the changes in concentrations, and determine the origin of groundwater sources despite different seasonal conditions. The data from this study was taken from a previous study and examined 18 water samples with different locations and weather conditions. Determination of 9 elements including alkalinity and trace elements was conducted as the main elements in this study. In the experiment, water temperature, pH, alkalinity, and free CO content were measured in situ from non-volcanic hot water, Odisha, India. In the process, the water was put into two polypropylene bottles, and cation and anion analyses were conducted in the laboratory. The results showed that seasonal differences clearly affected the changes in alkalinity concentration of each hot spring. However, hot springs with higher alkalinity experienced larger changes. In contrast, the analysed chlorine (Cl) concentrations 100 mg/L were more susceptible to shifts due to monsoon, whereas Cl concentrations 100 mg/L were more homogeneous despite the influence of monsoon (seasonal differences). Differences in the rainy season affected the concentration changes in Attri, Tarabalo and Deulajhari hot springs. Meanwhile, hot springs dominated by meteoric water such as Badaberena, Taptapani and Boden are less affected. This proves that Attri, Tarabalo and Deulajhari hot springs originate and are dominated by deep groundwater.
