 
Railpower’s ECO Crane™ hybrid power solution enables a reduction in fuel consumption and green-house gas emissions of RTG cranes by up to 70%. Railpower expects emission reductions in NOx and diesel particulates to be similar to what has been achieved with the GG-series locomotives. The power and energy requirements of RTG cranes used for unloading shipping containers are highly suitable for a hybrid application: frequent lifts require short bursts of power and most of the energy is regenerated when the container is hoisted down. The overall average power is only a small portion of the peak power, leaving room for significant fuel savings and reduction of diesel emissions. Replacing the on-board diesel generator power plant with Railpower’s ECO Crane™ battery-genset hybrid system achieves this full potential.
