TIDAL POWER: Economic and Technological Assessment

摘要: At present time there is concern over global climate change, as well a growing awareness on worldwide population about the need reducing greenhouse gas emissions. This in fact, has led to an increase power generation from renewable sources. Tidal energy potential play valuable role sustainable future. Its main advantage other sources its predictability; tides can be predicted years advanced. The extracted come both, vertical movements of water associated with rise and fall, energy, kinetic namely, tidal currents. A barrage harnesses while stream turbines capture thesis reviews physical principles considering gravitational effects sun moon; semidiurnal, diurnal mixed tides, periodic phenomena that affect range. Moreover, up-to-date review status technology included. Furthermore, different conversion systems are introduced, turbines. current issues for both technologies presented, aiming place reader situation. also contains economic assessment, where costs estimation future shown. levelised (LCOE), which measure cost generated electricity, calculated compared. From this chapter it concluded, although very high costs, clear become competitive forms will considerably decrease installed capacity increases. On hand said mature however deployment bring several benefits. Finally technological report purpose identify technology, one direction or two-direction turbines, generate more electricity under same operating conditions. It includes analysis types devices. conclusion raised bi-directional devices have lower costs.
