Bangor University KESS 2 PhD candidate Michael Ridgill has published his first paper in the International Journal Renewable Energy (Impact Factor 6.274). Michael’s research is focused on hydrokinetic energy conversion and the article describes the first iteration of a developing method for assessing the potential of this resource in the rivers of the world.
Hydrokinetic energy conversion, unlike conventional hydropower, is the process of electricity generation using instream turbines that harness the kinetic energy of flowing water. This contrasts with conventional hydropower, which uses impoundment of water behind a dam, building up a head of water and harnessing the gravitational potential energy of this elevated water.

“I believe this is the first attempt at a global resource assessment of this type. I am grateful for the support KESS 2 has provided, both financially and in terms of professional development, which has allowed me to reach this point in my research to-date.
The opportunities for developing the necessary skills to carry out this project has pushed me to significantly develop as a scientist. Working in partnership with my sponsor company, Repetitive Energy Company, has provided valuable insights into the young industry developing around this immature renewable energy technology.”
Prof. Simon Neill, lead supervisor, adds,
“This study puts a number, for the first time, on the size of the global riverine hydrokinetic resource, showing that it has huge potential for energy conversion – more than twice the global demand for electricity.”
Frank Moloney, of the sponsor company Repetitive Energy, states that,
“Establishing a global perspective of the potential for hydrokinetic energy conversion supports our aim to provide an innovative solution that can help support efforts to eradicate the problem of energy poverty, especially for isolated communities currently without access to electricity.
Our very exciting Smartstream vertical axis turbine offers a highly cost-effective solution to hydrokinetic energy conversion and we are actively looking for commercial partners to help us upscale the technology and bring Smartstream to market. Leading hydro businesses such as Statkraft AS, Agder Energi AS and SSE could benefit greatly through the application of Smartstream technology within their existing tail races and aquaducts.”
