The electrical efficiency of the photovoltaic (PV) panel is affected significantly with increased cell temperature. Among various approaches, use Phase Change Materials (PCMs) nanoparticles currently one most effective for reducing and managing temperature PV panels. In this study, paraffin wax as PCM different loading levels (0.5%, 1%, 2%) hybrid Al2O3 ZnO were successfully synthesized their effects on performance Photovoltaic-Thermal (PVT) system investigated experimentally. Additionally, a prediction model was developed to analyze interaction between operating factors (independent variable) response (dependent PVT/PCM PVT Hybrid nano-PCM (PVT/HNPCM) systems based surface methodology (RSM). Experimental results showed that compared only PCM, thermal conductivity HNPCM by 24.68%, 28.57%, 41.56% inclusion 0.5%, 2% nanomaterial respectively. PVT/HNPCM, enhanced 31.46% 28.70% respectively conventional in study. With cooling-water mass flow rate 0.0021 kg/s, highest 47% achieved system, whereas 51.28% PVT/HNPCM system. analysis variance test yielded P value <0.0001 which less than 0.05 overall indicating suggested model's appropriateness statistical significance. These optimal conditions are observed when solar intensity ranges from 774 W/m2 809 0.002 kg/s both systems. However, these advance sustainable urban development climate goals combining panels' generation energy harvesting, boosting built environment.

Energy management has emerged as a pressing concern in the planning and operation of smart cities, driven by escalating demand for energy. Concurrently, response programs (DRPs) have gained significant attention recent years, owing to their profound impact on power system. This paper introduces an approach aimed at minimizing operational costs environmental emissions within city reliant grid-connected power. A novel green energy scheduling multi-carrier community is presented achieve sustainable development. The proposed method places premium maximizing utilization renewable sources. Recognizing inherent uncertainty associated with resources, this seeks enhance system reliability addressing challenge. paper's primary objective tackle intricate problem while factoring stemming from resources integration DRPs. To address these complexities, leverages CPLEX solver embedded GAMS software application, uncertainties are modelled through application Monte-Carlo algorithm. results show that considering total cost can be reduced $504 performing

Abstract Since hydrogen produces no emissions, there is increasing interest in its production throughout the world as need for clean and sustainable energy grows. Bangladesh has an abundance of biomass, particularly wood pellets, which presents a huge opportunity gasification to produce hydrogen. Gasification mahogany ( Swietenia mahagoni - SM) mango Mangifera indica- MI) performed downdraft gasifier evaluate impact particle size, equivalence ratio, temperature on gas composition performance. Under optimal conditions determined by central composite design-response surface methodology (CCD-RSM) optimization, SM MI can greatly increase yield cold efficiency, offering workable, environmentally friendly, long-term solution Bangladesh's shortage pollution problems. Through RSM analysis best operating include feed size 22.5 mm, ratio 0.34, 1176 K, where total 11.2% was obtained. In case gasification, optimum condition found at 1132.47 12.85% The economic study provides LCOE 0.1116 $/kWh, project payback period be 10.7 years. By reusing waste from nearby sawmills, this helps manage sustainably lowering levels deforestation. It also highlights wider sustainability effects assisting international initiatives fight climate change advance independence.

Developing countries, including Ghana, face challenges ensuring access to clean and reliable cooking fuels technologies. Traditional biomass sources mainly used in most developing countries for contribute deforestation indoor air pollution, necessitating a shift towards environmentally friendly alternatives. The study's primary objective is evaluate the economic viability of using solar PV-based green hydrogen as sustainable fuel Ghana. study adopted well-established equations investigate performance proposed system. findings revealed that levelized cost discounted cash flow approach about 89 %, 155 190 % more than electricity, liquefied petroleum gas (LPG), charcoal. This implies produced not cost-competitive compared LPG, charcoal, electricity. However, with sufficient capital subsidies lower upfront costs, analysis suggests could become an attractive alternative fuel. In addition, switching from firewood yields highest carbon dioxide (CO2) emissions savings across cities analysed. Likewise, replacing charcoal also offers substantial CO2 savings, though firewood. Correspondingly, LPG produces growing body knowledge on energy solutions, offering practical insights policymakers, researchers, industry stakeholders seeking promote adoption economies.
