Besides cost considerations, ports must consider their impact on air quality both locally and globally. The community near ports may often be considered sensitive neighbours and maintaining the best possible relationship with them is a must.
Energy optimization in ports by implementing hybrid- and zero-emission solutions represent a huge potential.
Approximately 20 % of diesel fuel emissions from cargo handling operations at ports are emitted by Rubber Tyred Gantry cranes (RTG) and container handling equipment such as automated guided vehicles (AVGs). We see a protruding option of making equipment hybrid or fully electric thereby cutting costs and emissions with one single investment.
Corvus Energy has experience with making hybrid port cranes. Approximately 70 RTG cranes utilise Corvus energy storage systems (ESS) and are displaying great results with a decrease in fuel costs and environmental footprint both locally and globally.
Hybrid RTGs powered by Corvus Energy run primarily on battery power which leads to an unbeatable mix of fuel usage decrease by approximately 65% along with decrease in noise and chemical pollution.
The Corvus Energy ESS provides the required power for operating normally. This includes lifting and hoisting as well as moving the cranes between rows. The system is working in collaboration with a generator used for charging, however this generator may be significantly smaller than the ones originally in place and run at optimal levels. The system is also capable of regenerating energy from energy negative operations such as lowering of containers.
