Chinese Ports Go Green with Massive RTG Initiative
Marine energy storage giants Corvus Energy has announced it has been chosen by CCC Shanghai Equipment Engineering (CCCCSSE) to supply the Orca Energy Storage System (ESS) for its battery-hybrid RTG cranes.
According to a statement, the order is for various retrofits and new build deliveries by CCCCSSE’s affiliate ZPMC, which will be installed in major ports around China.
It will be the first order for Corvus Energy’s Singapore-based Asia office and adds to the 48 CCCCSSE RTG cranes it has previously serviced.
The Orca Energy ESS stories regenerative braking energy captured as the RTG crane lowers a container – a high-current charge that most battery systems cannot sustain.
The stored energy is used to power the RTG crane during operations such as trolley and gantry movement, which allows the diesel engine to be shut off when it would traditionally be idling or operating inefficiently at low loads.

The size of the generator can be smaller and the generator used more sporadically so that its operation is optimized for fuel efficiency.
Speaking about the order Pradeep Datar, Vice-President of Sales, Corvus Energy Asia, said: “The design and performance of Corvus Orca Energy enables the ESS to support aggressive load profiles with a significant reduction in cost.
“We expect the market for battery-hybrid RTG crane applications will continue to grow as leading port equipment suppliers such as CCCCSEE to prove the technology’s efficacy to significantly reduce emissions.
“There is significant retrofit potential with existing RTG cranes in global ports, in particular in Asia which operates half the world’s roughly 10,000 RTG cranes.
“Further, there is an upward trend for hybrid and all-electric RTG cranes in new orders. Corvus technology continues to provide solutions for progressive port operators worldwide who seek to increase efficiencies while reducing emissions and the environmental impact of their operations.”
