Today, the world is heavily dependent on fossil fuels, as most of the energy requirements are being met through conventional methods of burning these fuels. The energy demand is increasing day with growing population. Consequently, fossil fuel reserves are depleting continuously and will soon run out in coming years. Therefore, renewable energy resources have gained enormous attention in recent years. The growing interest in exploring tidal current technologies has many compelling reasons such as its renewable nature, tidal energy is cleaner than fossil fuels, intermittent but predictable, security and diversity of supply, and limited social and environmental impacts. Tidal current technologies are still in development phase, yet need some time to mature to prove their full potential. Tidal current turbine is an important tidal current technology. The purpose of this paper is to present a comprehensive review of tidal current turbine, its potential and associated challenges. The paper discusses general theoretical background of fluid flow in a tidal stream and forces governing the flow behavior. The author will also discuss the core issues and challenges faced in research and development such as unforgiving marine environment, corrosion, cavitation phenomena and extreme structural loads.
