Summary Increased demand of energy leads to exploration of new sources of energy. In the last few years, hydrokinetic energy technology emerged as an important area in the field of renewable energy generation. Various hydrokinetic turbines have been studied and used to harness the hydrokinetic potential. Among all hydrokinetic turbine technology, cross‐flow hydrokinetic turbine is considered as the most suitable approach for the riverine system. There are various configurations of cross‐flow hydrokinetic turbine exist for hydrokinetic energy extraction. A number of numerical and experimental studies were carried out on the performance enhancement and design optimization of different configurations under variable operating conditions. Under the present paper, review of different rotor for the configurations of the cross‐flow hydrokinetic turbines are discussed. The paper will be useful to understand the cross‐flow hydrokinetic technology in order to explore the methods for selection, performance enhancement, and design optimization of cross‐flow hydrokinetic turbines.

“…Miller et al estimated the cost of energy for installing 16 turbines per site in the rural communities of Ghana by implementing hydrokinetic technology and stated that the cost of hydrokinetic power plant per turbine includes material cost of $360, installation cost of $4750 per site, labor cost of $1276 per site, and maintenance cost of around 5.5% of the annual revenues and estimated that the expected cost of energy is around $0.035/kWh per user.…”

“…It was found that the estimated cost of energy for Igiugig and Eagle villages as shown in Table 5 is not commercially attractive, but for Whitestone village, the cost is cheaper than solar energy. Miller et al 25 Kusakana 94 carried out a techno-economic analysis on hydrokinetic technology working in eight different hybrid combinations on two different sites (rural household and base transceiver station) using Hybrid Optimization Model for Electric Renewable (HOMER) and among eight combinations, which include HKT (hydrokinetic turbines), PV (photovoltaic panels), WT (wind turbines), DG (diesel generators), HKT + PV, HKT + DG, PV + DG, and HKT + PV + DG; the best option is selected on the basis of net present cost and cost of energy. The obtained net present cost and cost of energy as shown in Figure 13 and Table 6 reveal that the hybrid system composed of HKT + DG not only is the best suitable option for economical supply for both sites but also contributes in the reduction of carbon dioxide pollutant.…”

Summary The drastic change in climatic conditions has led to shift towards the review of sustainable strategies in the renewable energy sector. Hydrokinetic technology has various benefits over the conventional methods, which can be helpful in achieving the desired sustainable development. In the present study, an outline for the conversion of hydrokinetic energy along with its challenges has been discussed. The study comprises of three steps involving collection of properties required for site characterization followed by selection of the suitable hydrokinetic device as per the site characteristics and the determination of impact on the flow condition due to device installation. The characteristics of the site govern the selection of the device, its mooring arrangements, and augmentation. The arrangement of devices as a single unit or in an array will have an impact on the flow conditions. The altered flow condition will in turn affect and change the characteristics of the site. This three‐step process is interlinked and will have a cumulative impact on the environment. The influence of environmental impact and cost of energy, which are the two major factors for the success of this technology, are also discussed. Further, various challenges faced by hydrokinetic technology in its development are explored. It is concluded that only the optimization of a hydrokinetic device for its efficiency improvement will not be fruitful until its impact on flow condition is considered for optimization.

“…Slope is a strong factor influencing power potential although there are other factors influencing the output of hydrokinetic power production in Ikere Gorge basins. Miller et al (2010) reported that Hydro Kinetic Power [HKP] has a lower cost per unit of energy extracted than Hydro Potential Power [HPP] system, and is economically compared with other distributed system such as solar, wind and others making it a better method for policy support and compliance. Therefore, government and non-governmental organization should invest on hydrokinetic energy for human and socio-economic building of the country including industrial growth and development.…”

The operation of hydrokinetic turbine depends on river flow and pressure head (∆H) which are of high potential in many parts of Nigeria. This study attempts the analysis of the potential of the area upstream of Ikere Gorge dam for hydrokinetic potential. Soil and Water Assessment Tool (SWAT) was used to determine the hydrological parameters of the sub-basins. Pearson Moment Correlation and linear regression methods were used to find the relationships between morphometric properties and the discharge parameters. Hydrological modeling and statistical computations were done to estimate the theoretical potential of the catchment. The result shows that River Oshe has 9.542 MW, which is the highest potential while River Konsun with 1.161 MW has the lowest potential Pearson Moment Correlation shows that there is strong positive relation of 0.7 between slope and pressure head (∆H) at 0.05 significant levels. The result of the multiple regression show that hydro-geomorphic factors explained 59.1% of the variance in the explanation of hydrokinetic power potential upstream of Ikere gorge dam. The result shows that higher discharge is a function of more hydrokinetic energy that can be produced in the Basins. It is therefore expected that the variation in hydro geomorphic properties of the Basin will not affect substantial amount of hydrokinetic energy that can be produced from upstream of the basin under study. Hence, further work is expected to be replicated in some potential basins, across the country, for Hydrokinetic power production.
