In this investigation, an innovative modification process has been employed to enhance the capability of a novel multi-generation energy system (MGS) utilizing dual-flash binary geothermal cycle incorporated with two main subsystems. These subsystems include cooling, heat, and power (CCHP) unit by ejector-based cooling (ERC) joint organic Rankine (ORC) hydrogen generation setup via low-temperature electrolyzer. addition, mixture consisting Pentane R142b utilized for CCHP subsystem as working fluid. Nonetheless, assess actual operating cost investigated system, exergetic level-based exergoeconomic (modified exergoeconomic) analysis implemented instead using conventional analysis; afterward, due conflicting trend between design performance parameters, dual parametric sensitivity study double-objective optimization NSGA-II approach have carried out. According outcomes study, results are further sensitive simultaneous variation in second flash tank inlet pressure vapor generator temperature. Optimization indicate that net electricity production increased from 33.04 kW 40.59 kW, which improves efficiency 4.39 %. Also, case, total product ameliorated 3.4% 2.62% terms modified approaches. The best representative optimal solution energetic efficiency, 38.35%, 43.50%, 52.52 $/GJ, respectively.

Assessing renewable energy efficiency and policies: A combined analysis of LMDI, super-SBM, and fieldwork in Qinghai, China

Energy Sustainable Development/Energy for sustainable development, Год журнала: 2024, Номер 80, С. 101420 - 101420

Опубликована: Март 20, 2024

The significance of renewable energy as a pivotal green industry in decarbonizing the global economy and addressing climate change is profound. rise China's regional serves testament to its transition from an industrial powerhouse leader sustainable growth, offering valuable insights for future worldwide. This study analyzes efficiency, alongside factors that influence it, Qinghai Province over 2000–2021. It uses combination Logarithmic Mean Divisia Index factor decomposition, Data Envelopment Analysis Super-SBM models, field research with rounded approach. finds robust increase capacity, particularly after 2016. Efficiency generally has risen, although periods inefficiency were noted 2014 2019. Despite fluctuations, overall impact such structure, electricity intensity, security, carbon productivity, emissions, all contribute positively development energy, notably recent years. paper concludes discussion policies wider implications sector.

Assessment of a Hybrid (Wind-Solar) System at High-Altitude Agriculture Regions for achieving Sustainable Development Goals

Engineering Technology & Applied Science Research, Год журнала: 2024, Номер 14(1), С. 12595 - 12607

Опубликована: Фев. 8, 2024

Power generation from hybrid renewable energy systems is gaining popularity worldwide, especially in developing countries suffering electricity crises. Small-scale wind and solar systems, high-altitude agriculture regions, which may experience shortages during extreme weather conditions, can be critical to achieving sustainability goals objectives. The latter will reached by providing clean addressing economic concerns. Accordingly, the main aim of current paper evaluate techno-economic feasibility a grid-connected (vertical axis turbine – 2-axis photovoltaic) system at regions (Ardal Faridan) Iran for production energy. To this aim, speed radiation data were analyzed statistically using 13 distribution functions. results indicate that Generalized Extreme Value produced best fit data. Furthermore, purpose work technical aspects vertical turbines as well PV tracking RETScreen software. demonstrate implementing proposed could generate significant amounts order meet demand domestic agricultural applications while ensuring line with sustainable development goals. Besides, study help integrate into grid policymakers facilitate installation rooftop small-scale future.

In the last decades, researchers have been considering some fundamental issues such as energy saving, global warming, greenhouse emissions, and non‐renewable to make models of house environmental standards achieve a suitable consumption pattern for saving energy. architecture, using natural is one essential pillars design because it was criteria designing, which considered on climate geography, has high performance adaptation in modeling traditional houses. this research, Azerbaijan (located northwestern Iran) selected evaluate practical features Iranian houses designed cold climate, developing sensible solutions model are provided. The primary purpose paper identify residential buildings management, components affecting saving. data collection method based checklists, observation, orientation, density, solar radiation angle region, documentary, analysis maps, architectural plan studied with area. This research discusses future structures their adaptable measures obtained results. Finally, declared that follows region’s climatic conditions, current energies, were designed; therefore, best maximum use available design. As result, suggestions made regarding architecture save
