© 2020 Elsevier LtdThe trend of utilizing renewable energy sources is witnessing a brisk growth around the world. Among the various sources of renewable energy, hydropower is considered the most favorable due to its high potential and distinct advantages such as predictability, high energy density etc. Moreover, to extract the hydrokinetic energy from flowing streams, different designs of hydrokinetic turbines have emerged which operate on a similar principle as the wind turbines. The Savonius turbine is a drag-based device reported to have good starting characteristics, which makes it a fitting choice for hydrokinetic energy extraction, especially in low-velocity flows. However, along the development, it was noted that somehow this turbine has a poor energy conversion efficiency. To overcome this limitation, various design optimization strategies have been proposed. This paper attempts to review the optimization studies of Savonius turbine regarding its probable applications in harnessing hydrokinetic energy. The studies concerning each of the structural parameters influencing the turbine performance are discussed thoroughly. There is hardly any review study available hitherto, which exclusively discusses and summarizes the optimization studies conducted for Savonius design by solely considering water as the operating medium. Hence, the data presented in this study will serve as a basis to understand the existing research on Savonius turbine, thereby enabling researchers to fill the gaps in this area with reference to hydrokinetic applications.

An investigation of optimum PV and wind energy system capacities for alternate short and long-term energy storage sizing methodologies
Al-Ghussain, Loiy; Taylan, Onur; Baker, Derek Keıth (Wiley, 2019-01-01)
The goal of this study is to find the optimal sizes of renewable energy systems (RES) based on photovoltaic (PV) and/or wind systems for three energy storage system (ESS) scenarios in a micro-grid; (1) with pumped hydro storage (PHS) as a long-term ESS, (2) with batteries as a short-term ESS, and (3) without ESS. The PV and wind sizes are optimally determined to accomplish the maximum annual RES fraction (F-RES) with electricity cost lower than or equal to the utility tariff. Furthermore, the effect of the ...
A METHOD FOR TECHNICAL ECONOMIC-ANALYSIS OF SOLAR HEATING-SYSTEMS
TASDEMIROGLU, E; ARINC, F (Elsevier BV, 1988-01-01)
The necessity for technical-economic analysis of solar energy systems is obvious when assessing their feasibility vis-á-vis conventional alternative systems. Optimum magnitudes of the installation parameters should be defined under the required economic conditions. In this study, the optimization procedure was chosen so as to maximize the total accumulated saving throughout the economic lifetime of the system. The annual solar heating fraction of the system is assessed using the f-chart method which can be ...
The potential and economic viability of solar photovoltaic power in Ghana
Asumadu-Sarkodie, Samuel; Owusu, Phebe Asantewaa (Informa UK Limited, 2016-01-01)
In this study, the potentiality and economic viability of solar photovoltaic (PV) in Ghana was assessed using RETScreen software. 5 MW of grid-connected solar PV power system using SunPower SPR-320E-WHT-D PV module can be harnessed from Navrongo, Bawku, Wa, Tema, Bolgatanga, Axim, Salaga, Kintampo, Kete Krachi, Tamale, Hohoe, Koforidua, Ejura, Takoradi, Bole, Sunyani, Bibiani, Cape coast, Prestea, and Akuse, which requires US$17,752,179 of investment capital and 25,313 m(2) of land for PV installation. The ...
GIS-based site selection methodology for hybrid renewable energy systems: A case study from western Turkey
Aydin, Nazli Yonca; Kentel Erdoğan, Elçin; Duzgun, H. Sebnem (Elsevier BV, 2013-06-01)
Renewable energy sources are presently being considered as alternatives to fossil fuels, because they are perpetual, environmentally friendly, and release negligible amounts of greenhouse gases to the atmosphere while producing energy. A disadvantage of renewable energy systems, however, is that continuous energy generation is not possible by using only one type of renewable energy system, since renewable energy resources depend on climate and weather conditions. Two or more renewable energy systems can be ...
The Evaluation of an Immiscible-CO2 Enhanced Oil Recovery Technique for Heavy Crude Oil Reservoirs
Kök, Mustafa Verşan (Informa UK Limited, 2012-03-01)
Sequestration of CO2 in enhanced oil recovery applications has been widely recognized as one of the favorite techniques for reducing emissions of CO2 into the atmosphere in response to global climate change. This technique provides lower costs for CO2 sequestration by means of higher incremental oil recoveries. There are some key parameters, when considering a.field for the CO2 displacement. Oil reservoirs are screened out according to oil gravity, reservoir temperature and pressure, minimum miscibility pre...
