Abstract

L'invention concerne un type de centrale d'accumulation par pompage qui est situé dans des eaux, principalement dans les mers. Le coeur de la centrale d'accumulation est formé par des bassins disposés verticalement les uns au-dessus des autres, lesquels permettent la réalisation de processus de remplissage et de déversement du milieu constitué par l'eau, visant à générer une énergie potentielle, respectivement une hauteur de chute, et par conséquent, une production de courant électrique. Les bassins supérieurs communiquent avec les bassins inférieurs par des canaux d'écoulement réglables, des turbines hydrauliques qui se trouvent dans les bassins inférieurs étant sollicitées de façon à entraîner des générateurs électriques destinés à délivrer de l'énergie électrique sous forme de courant. Le réservoir est rempli de telle manière que des pompes à eau, qui sont entraînées par des moteurs électriques, pompent l'eau des bassins inférieurs et l'envoient dans la mer. Ainsi, on réussit à convertir en énergie potentielle l'eau du réservoir supérieur à partir du courant apporté afin d'accumuler l'énergie électrique destinée aux pompes à eau, en acceptant des réductions de rendement. Les centrales d'accumulation par pompage en mer offrent, de préférence, les possibilités d'accumulation nécessaires aux centrales électriques alternatives, telles que les parcs éoliens ou les centrales solaires de tout type, sans que le milieu constitué par l'eau ne vienne à manquer.
