NorthPort cuts carbon emissions with hybrid RTG conversion

NorthPort takes a significant step toward more sustainable operations with the conversion of its rubber-tired gantry (RTG) cranes into hybrids. The conversion enables the RTGs to operate more efficiently while reducing the terminal’s carbon footprint.

Six RTGs were converted into hybrids by replacing their diesel generator sets into smaller generators and paired with high-capacity, liquid-cooled battery systems. These now run primarily on batteries, which are recharged by the smaller generator sets resulting in reduced diesel consumption and maintenance requirements.

The initial batch of hybrids is now fully operational, achieving a 49-percent reduction in carbon emissions and diesel consumption. This lowers the terminal’s average annual carbon emissions by half from 2,186 tons to an estimated 1,109 tons.

Moreover, NorthPort is expanding its hybrid RTG fleet with the acquisition of four new Mitsui hybrid units, scheduled for delivery in the fourth quarter of 2026.

The adoption of hybrid technology underscores NorthPort’s commitment to environmental stewardship, world-class port operations, and exceptional customer service.

The initiative supports the terminal’s sustainability roadmap, aligns with global standards for responsible port operations and ensures the terminal’s adaptability while contributing to the Philippines’ environmental and economic goals.
