Terminal operator SSA Marine will retrofit 13 rubber-tyred gantry (RTG) diesel-powered cranes with diesel hybrid diesel-electric engines at its Oakland facility.
The US$6m upgrade is estimated to eliminate more than 45 tonnes of exhaust emissions annually at the Port of Oakland, with the hybrid cranes operating primarily on electric and only using diesel for battery charging. The cranes will also regenerate battery power while lowering containers.
Greenhouse gas emissions from the cranes could fall by at least 40%, while the port estimated emissions from other air pollutants could fall by 99%.
The port said it could take two years to fully outfit SSA’s terminal, the largest at Oakland, with hybrid cranes.
The project was funded largely by US$5.1m grant which was supplied by the Community Health Protection Grant Program and approved by the Bay Area Air Quality Management District.
