Le principe est simple, lorsque l’on a de l’\u00e9nergie disponible \u00e0 stocker, la grue monte des blocs de b\u00e9tons pour cr\u00e9er une tour de grande hauteur. Lorsque l’on veut r\u00e9cup\u00e9rer l’\u00e9nergie, il suffit de redescendre les blocs au sol et de transformer l’\u00e9nergie cin\u00e9tique produite  en \u00e9nergie \u00e9lectrique via un alternateur coupl\u00e9 au r\u00e9seau. Une solution adapt\u00e9e aux parcs \u00e9oliens et  solaires, mais \u00e9galement aux centrales \u00e9lectriques traditionnelles.<\/p>\n

Syst\u00e8me modulaire et flexible.<\/strong><\/p>\n

\"\"<\/a><\/p>\n

Les blocs fabriqu\u00e9s \u00e0 partir de mat\u00e9riaux de r\u00e9cup\u00e9ration, ont une forme sp\u00e9cifique permettant leur manipulation et leur positionnement. Un logiciel de contr\u00f4le assure la gestion du positionnement des blocs les uns par rapport aux autres, en les pla\u00e7ant au bon endroit. Du fait que c’est un syst\u00e8me m\u00e9canique, il  est adapt\u00e9 au stockage de longue dur\u00e9e et souple d’utilisation pour compenser des demandes instantan\u00e9es de charge sur le r\u00e9seau. La capacit\u00e9 de l’installation est comprise entre 10 et 35 MWh avec une puissance de sortie de 2 \u00e0 5 MW.<\/p>\n

Le rendement annonc\u00e9 se situe entre 85 et 90%, que l’on peut comparer \u00e0 celui d’une station de transfert d’\u00e9nergie par pompage d’eau qui se situe aux alentours de 70%, avec pour celle-ci la n\u00e9cessit\u00e9 de disposer  d’une r\u00e9serve d’eau.<\/p>\n

La r\u00e9alisation d’une premi\u00e8re tour tour est pr\u00e9vue en Inde pour le compte de Tata Power<\/p>\n
