River flow hydrokinetic devices have several advantages, but there is also one major drawback of this technology compared to other hydrokinetic technologies. The density of the energy is relatively low in the flow of a river. Channelling devices such as diffusers and ducts are the means that allow for efficient concentration of this energy as well as provide other benefits that enable more efficient energy production with hydrokinetic devices. This work serves as the concise overview of the benefits, challenges and opportunities that channelling devices offer. A method for evaluation and comparison of the gains that use of different channelling devices may offer is proposed based on the overview. Conclusions regarding further research and development of channelling devices are drawn.
