Abstract

L'invention concerne une centrale à accumulation avec réservoir (100) comportant : un conteneur (4) disposé dans un réservoir de liquide ; un tube de purge (3) dont l'une des extrémités est raccordée au conteneur (4) et l'autre extrémité fait saillie par rapport à la surface du liquide dans le réservoir lorsque celui-ci est rempli au maximum ; et un tube de liaison (7) qui relie l'intérieur du conteneur (4) à une pompe (6), si bien que du liquide peut être pompé à partir de l'intérieur du conteneur (4). Lorsque celui-ci revient dans le conteneur (4) par le tube de liaison (7), il peut entraîner un générateur à l'aide d'une turbine. L'intérieur du conteneur (4) est rempli d'un matériau en vrac (13), si bien que le liquide peut être stocké à l'intérieur du conteneur (4) dans les espaces entre les particules du matériau en vrac, la densité du matériau en vrac (13) étant supérieure à celle du liquide. L'invention concerne en outre un procédé de fabrication d'une telle centrale à accumulation avec réservoir.
