RTG tests may give ports a breath of fresh air

POLA has been awarded a $731,000 grant to test out new technology that could significantly reduce diesel emissions and greenhouse gases from rubber-tyred gantry cranes (RTGs).

The EcoCrane technology involves replacing a conventional 685-horsepower diesel engine on a RTG with a downsized 105-horsepower diesel engine that charges a battery pack. The battery pack drives an electric motor that powers the gantry operation. Because the engine runs only periodically to maintain the battery charge, the EcoCrane can reduce particulate matter up to 85% and greenhouse gases up to 70%.

The EcoCrane will be tested over the next 12 months by Ports America at the West Basin Container Terminal to verify the projected emission reductions by the US EPA. If the test is a success, the port will consider requiring the EcoCrane technology when future terminal leases are renewed.

Executive director Geraldine Knatz, says, “In the long-run, emissions reduction technology for such a common and critical piece of cargo handling equipment can be a benefit for ports everywhere.”
