Al- 19 though there has been much commercial and R&D progress in tidal stream 20 energy, tidal range is a more mature technology, with tidal range power plants 21 having a history that extends back over 50 years. With the 2017 publication 22 of the \Hendry Review" that examined the feasibility of tidal lagoon power 23 plants in the UK, it is timely to review tidal range power plants. Here, we 24 explain the main principles of tidal range power plants, and review two main 25 research areas: the present and future tidal range resource, and the opti- 26 mization of tidal range power plants. -

TIDAL POWER: Economic and Technological Assessment
Master thesis TIDAL POWER: Economic and Technological assessment Author: Tatiana Montllonch Araquistain Professor: Wang Zheng Wei Department of Thermal Engineering Tsinghua University ABSTRACT At present time there is concern over global climate change, as well as a growing awareness on worldwide population about the need on reducing greenhouse gas emissions. This in fact, has led to an increase in power generation from renewable sources. Tidal energy has the potential to play a valuable role in a sustainable energy future. Its main advantage over other renewable sources is its predictability; tides can be predicted years in advanced. The energy extracted from the tides can come from both, the vertical movements of the water associated with the rise and fall, potential energy, and from the kinetic energy, namely, tidal currents. A tidal barrage harnesses the potential energy while tidal stream turbines capture the energy from tidal currents. This thesis reviews the physical principles of tidal energy considering gravitational effects of sun and moon; semidiurnal, diurnal and mixed tides, and periodic phenomena that affect tidal range. Moreover, an up-to-date review of the status of tidal energy technology is included. Furthermore, the different tidal conversion systems are introduced, tidal barrage and tidal stream turbines. The current issues for both technologies are presented, aiming to place the reader on the current situation. The thesis also contains an economic assessment, where the current costs of both technologies as well as an estimation of the future costs are shown. The levelised costs of energy (LCOE), which measure the cost of the generated electricity, are also calculated and compared. -
