Port

Ports around the world are looking to become more sustainable and are considering all major operations for technology that can reduce the impact from port operations.

Besides cost considerations, ports must consider how air quality, both locally around the port and globally, is impacted by their operations. The communities near ports are often sensitive neighbours with whom the ports need to maintain healthy relations.

Energy optimalization in ports by implementing hybrid and zero emission solutions represents a huge potential.

Approximately 20% of diesel fuel emissions from cargo handling equipment at ports are emitted by RTG cranes and other container handling equipment, such as automated guided vehicles (AGVs). In addition al lot of the portgoing vessels can be electrified with great results

Hybrid Port cranes

Corvus Energy has extensive experience in hybrid portcranes.

Corvus Energy has supplied Corvus Orca ESS for more than 70 RTG cranes The use of battery hybrid technology  has proven very successfull and  substantially reduces fuel consumption and harmful fossil fuel emissions.

The implementation of a hybrid electric system provides significant fuel savings and greatly reduces GHG emissions. Unlike conventional diesel electric port cranes, the hybrid version is powered primarily from the Energy Storage System (ESS) resulting in fuel savings of up to 65% with the added benefits of reduced operating costs, reduced greenhouse gas emissions and lower noise levels at the terminal.

The ESS provides the required power for lifting and hoisting activities, as well as moving the cranes between rows. The ESS is installed to supplement the generator and the generator is required to charge the ESS during operations. The RTG’s primary generator can be replaced with a smaller generator unit. The smaller generator then operates much more efficiently running constantly close to its most efficient power level. The ESS also provides a mechanism to capture regenerated power from the RTG’s lifting activities. Regenerative power is captured in the ESS during lowering of containers on to trucks or the stacks and this regenerated power can be used to charge the ESS.
