“…For instance, the case study in Australia evaluated the performance of small axial flow turbines for the Nguiu community in Apsley Strait to replace the use of diesel fuel [43]. The works of Chihaia [15] also give a detailed review and present the works of numerous case studies performed by researchers from the inception of the technology conducted in Brazil until the concept's acceptance in Indonesia. In the case studies below, certain countries in Africa were selected from different regional boundaries to showcase the status of the technology and its adoption for rural remote electrification.…”

“…Generally, renewable energy sources such as biomass, solar, wind, hydro and geothermal offer clean and reliable energy and, at the same time, help to reduce greenhouse gas emissions that have an effect on the global warming. This is highly regarded as part of the environmental requirements assumed by the Kyoto Protocol to the Framework Convention of the United Nations on Climate Change [15]. Coupled with the 2015 Paris Agreement presented on the global ambitions to achieve sustainability between anthropogenic emissions by sources and the removal of greenhouse sinks, this accord aims to cultivate an increase in the global average temperature below 2.0 • C and to enforce a limit of 1.5 • C [16].…”

Status of Micro-Hydrokinetic River Technology Turbines Application for Rural Electrification in Africa

Energy accessibility, reliability and availability are key components of improved quality of life and human development in all spheres. As the United Nations’ SDG 7 calls for access to electricity for all by 2030, Africa still has a wide gap to fill as the statistics show that 85% of the population that will not have access to electricity is in Africa. As the world tries to wean itself off non-renewable energy and transition to green through use of renewable energy sources, hydropower energy remains at the heart of Africa for this venture. With majority of the rural population in Africa lacking electricity, there is need for a low-tech system that utilizes river flow to generate just enough energy for normal operation in these regions. Micro-hydrokinetic river turbine technology (µ-HRT), which offers less intermittency, can potentially contribute to sustainably electrifying Africa rural areas. The technology has been adopted by few countries worldwide, with limited comprehensive study in Africa even though the technology seems viable for use in African rivers. This paper reviewed the status of the µ-HRT applications in Africa and some of the barriers to its development. The study found out that the technology has not been vastly developed in Africa. Despite numerous barriers, the technology is simply a low-tech technology that requires the use of local resources and capacity building for its sustainability in terms of construction, operation and maintenance requirements. It is therefore recommended that R&D and field trials be conducted for its possible adoption.

“…Classic solutions are constantly improved and in parallel, new solutions are developed worldwide that offer higher yields [7][8][9]. In [10] an experimental model of the hydrokinetic turbine is presented and many flow velocities and rotational speeds were investigated to characterize the turbine efficiency. These kinds of turbines are simple to install and operate and the maintenance costs are convenient, but predicting turbine performance is essential for large-scale implementation [11,12], thus, many different prediction models are developed.…”

The main objective of the paper is to demonstrate the functionality and reliability of a hydrokinetic turbine system – a submersible electric generator, suitable for very low watercourses. To achieve this goal, it is necessary to design and build a prototype of a hydrokinetic turbine, coupled with an electric generator with excitation made with permanent magnets. This paper presents an analytical model and a finite element numerical model for estimating the electrical parameters of the generator (voltage, current, power, etc.). The two models were compared, and the results were extrapolated, in the analytical model, for several speed values.
