“…Therefore, scientists have highlighted the importance of geothermal promotion to strengthen energy development in areas with resource scarcity problems [96]. This promotion can be achieved with multi-generic projects that allow optimal use, such as urban buildings that require electricity, heating, or cooling [107]. Under this premise, it is possible to affirm that any mechanism promoting the direct use of geothermal energy requires incorporating planning aspects related to territorial use.…”

Geothermal energy, an efficacious and readily available resource, has emerged as a sustainable alternative poised to satisfy escalating global energy demands. This study undertakes a comprehensive analysis of low (heat below 100℃) and medium (heat between 100℃ to 150℃) enthalpy geothermal energy through a bibliometric approach and a literature survey, with an emphasis on the environmental and economic aspects. The methodological procedure encompasses: (i) systematic information processing and configuration, (ii) bibliometric assessment of the evolution and domains of the investigated field, (iii) evaluation of environmental and economic contributions, and (iv) Strengths, Weaknesses, Opportunities and Threats (SWOT) analysis, facilitated by a Focus Group comprising experts from the energy sector. The research on low and medium enthalpy geothermal energy has been identified as an expanding field, with five primary areas of focus: sustainability, cascade systems, heat pumps, numerical modelling, and groundwater potential in geothermal systems. Italy, the United States, and Germany have been recognized as the leading contributors in terms of scientific production. Geothermal energy, from an environmental standpoint, aids the decarbonisation process, reducing reliance on fossil fuels and other renewable energy sources. Although initial investment costs are considerable, the financial recovery period is relatively short. The promotion of geothermal energy, alongside the active involvement of academia, corporations, and governments, bolsters energy and socio-economic development, thereby contributing to the achievement of the Sustainable Development Goals (SDG).

“…To bridge this research gap, it is aimed in this study to assess different configurations of organic Rankine cycle (ORC) plants for optimal power generation from a typical biomass fuel in Nigeria. The choice of ORC technology is due to its global acceptance as a sustainable power conversion technology that is particularly suited for renewable energy resources [31], [32], [33], [34], [35], [36], including industrial waste heats [37], [38]. More so, several biomass-fired ORC plants have been installed in several countries already, most of which are currently running profitably [39], [40].…”

This study investigated the optimal design choice among four organic Rankine cycle (ORC) configurations for efficient utilization of solid biomass energy in Nigeria. Although vast opportunities exist for large-scale biomass power plants in the country, there has been little or no practical implementation yet, due to the limitation of technical know-how regarding thermodynamic conversion technologies. To bridge this gap, a thermodynamic optimization technique was applied in this study to the ORC. Specifically, the subcritical ORC (SUBORC), the regenerative subcritical ORC (SUBORC-REGEN), the supercritical ORC (SUPERORC), and the regenerative supercritical ORC (SUPERORC-REGEN) configurations were compared using established zero-dimensional optimization models implemented in MATLAB. Results showed that the SUPERORC-REGEN would be the most preferred choice amongst the options compared. Specifically, a palm kernel expeller (PKE) biomass fuel considered could yield about 1.98 MW of power at a thermal efficiency of about 28%. Additionally, it was obtained that the supercritical ORC would always outperform the subcritical types technically, with or without a regenerator. For the regenerative configurations, results showed that the supercritical ORC would generate 113 kW and 429 kW more net power than the subcritical ORC, respectively for n-pentane and n-butane working fluids. Similarly, the study reiterated that adopting a regenerative configuration would improve ORC performance. For instance, the SUPERORC-REGEN yielded 63% and 73% more power than the SUPERORC, respectively for n-pentane and n-butane working fluids. The practical economic implications of the different ORC configurations should be examined in future studies, alongside the investigation of exergy-based optimization potentials on component basis.

“…The effective utilization of thermal energy from lowtemperature resources like solar energy, waste heat from biomass combustion, industry and household waste fulfils many domestic and industrial needs such as ice-making, vaccine safety, storage of milk, fruits, vegetables, food, space cooling as well as air conditioning [3][4][5][6][7][8][9][10]. Since the heavy use of airconditioning systems in hot weather demands high amount of electricity, heat-operated cooling systems like adsorption refrigeration system (ARS) could be an effective choice to produce cooling effect using low grade thermal energy available at temperatures less than 100 o C to reduce the dependency on conventional electrical power.…”

The ever increasing cooling demand and the environmental concern have made in search of alternative refrigeration and for the last few decades, the energy efficient cooling systems utilizing refrigerants of no negative impact on the environment are explored. In this view, heat-driven refrigeration systems like vapour adsorption refrigeration is one of the favourable alternatives. Though adsorption cooling devices are capable of producing desirable cooling effect with a relatively low heat source temperature, their coefficient of performance (COP) is low in comparison with the existing cooling technologies. Therefore, to solve the environmental, economic and technical issues, the research is still in progress in this area. It is evident from the literature that, the performance of adsorption refrigeration depends on selecting the working pair such as silica gel-water, activated carbon-ammonia, zeolite-water etc. and driving temperature. This paper presents the comparison of performances of solar assisted twin bed adsorption refrigeration which employs silica gel-water and activated carbon-methanol as working pairs. Results are found to be good with continuous cooling in the evaporator using low temperature source of heat and the lowest temperature achieved in the evaporator for silica gel-water is 11°C and for activated Carbon-Methanol is 2°C. The coefficient of performance obtained is higher for silica gel based system than that of Activated carbon based system.
