Port Cranes


< 200 kWh

Corvus Energy has delivered batteries to 25 hybrid RTG cranes of 170 kWh to the port of South Carolina. The hybrid cranes can be powered primarily by the Corvus batteries, resulting in the estimated 65% fuel savings and reduced operating costs, as well as lower GHG and particulate emissions and noise levels in the port along with enhanced crane performance and reliability. Further, system efficiency can be enhanced to 96% by channeling regenerative energy back to the battery during container lowering operations.
