Energy storage
There are two energy storage systems in the complex of works to safeguard Venice and its lagoon.
The first system consists of batteries of electric accumulators housed on the closing dams of the emissaries of the lagoon, which receive and accumulate electricity produced by hydroelectric turbines for small gradients lodged in the dams that close the port inlets.
The energy they accumulate is mainly used to maneuver the dams using electric motors.
The second system, by far the largest, accumulates potential mechanical energy produced by at least one system which transforms the energy of the sea's tides into mechanical energy. It can also accumulate mechanical energy produced by particular patented wind turbines specific for lagoon environments and lake.
The first system supplies electricity.
The second system supplies electrical energy, transformed by at least one electric generator, and moreover it can directly supply mechanical energy, for example to operate hydraulic pumps directly without transformation from mechanical to electric energy and subsequently from electric to mechanical, thus avoiding loss of energy efficiency.
