With the recent deployment of two massive, all-electric harbor cranes, the Port of San Diego is about two-thirds of the way from reaching its ambitious zero-emissions targets. “This is a big, big deal,” port chairman Frank Urtasan said Tuesday as crane operators put on a demonstration for state, city and elected officials at the port’s Tenth Avenue Marine Terminal. Soaring 262 feet high and weighing 685 metric tons each, the pair replaces one older crane that ran on diesel fuel. The move will slash greenhouse gas emissions by 47 metric tons per year. In use since March, the cranes significantly increase the capacity for on-loading and of-loading cargoes on-loaded at the Tenth Avenue Marine Terminal from 100 metric tons to as much as 400 metric tons. “What that means for San Diego is we have the highest lift capacity, essentially, from our border with Canada to all the way down to the Panama Canal,” said Greg Borossay, principal of maritime business development at the port. The cranes, which can move from berth to berth, are the first all-electric mobile cranes installed at any port in North America.   Isaiah Cabral, equipment operator for the Port of San Diego, behind the controls of one of two all-electric Generation 6 Mobile Harbor Cranes at the Tenth Avenue Marine Terminal that rise 262 feet into the sky.

The port will spend an additional $8.9 million on electrical infrastructure improvements. That’s a total price tag of about $23 million, a big chunk of the port’s budget of roughly $200 million. But a combination of local, state and federal dollars helped defray costs. The port received a $2.7 million grant from San Diego County Air Pollution Control District, about $14 million in American Rescue Plan Act funds that are administered by the California State Lands Commission and $3.6 million from California’s Low Carbon Fuel Standard in which proceeds are accrued through the state’s cap and trade program. Port officials expect the project will have a payback period of 11 to 13 years. “When you operate the cranes, you use the existing power grids here,” said Robert Vennemann, marketing manager for Kronecranes. “So you’re just buying electricity, which in most countries in the world is cheaper than diesel (fuel).” The electric cranes are expected to reduce diesel particulate matter emissions from cargo handling equipment by 15 percent at the Tenth Avenue terminal. The cranes are one part of a $125 million effort spent thus far to meet the port’s Maritime Clean Air Strategy to transition all cargo handling equipment to zero-emissions by 2030. “Yes, it’s expensive, $125 million is a lot of money,” Urtasan said. “But we’re doing it in a way that is getting great results.” Earlier this year, the Port of San Diego became the first in the U.S. to launch an electric tug boat — the 82-foot eWolf, operated Crowley Maritime Corporation. Capable of speeds of up to 12 knots, the tug has bollard pull (that is, thrust) of 76.8 short tons, which is more powerful than the port’s diesel-powered counterparts.

Cleaning up emissions from trucking heading in, moving around and exiting the port will represent the final phase. The efforts will help clean the air at nearby South Bay communities such as Barrio Logan, Logan Heights and National City. “It also has benefits for port workers,” said Liane Randolph, chair of the California Air Resources Board. “Workers here at the port are already exposed to the same diesel pollution, but at closer proximity. So transitioning this equipment to zero-emission also protects the workers here at the port.” Related Articles Energy | ‘Biggest environmental victory’: After more than a decade in limbo, San Diego County has a new climate plan Energy | A microgrid project at Viejas gets a macro boost Energy | County wants buffer zones, safety rules after battery storage fires disrupt neighborhoods Energy | County votes to support state lawsuit against oil companies Energy | Heat wave’s last hurrah? Brutal temps broil San Diego County for a 6th day, but outages abate The electric cranes and other infrastructure are hooked up to a microgrid the port recently unveiled. The target cargo for the two cranes will be renewable energy projects, such as batteries and large pieces of equipment that go into assembling wind farms built around the West. “We’re going to be able to tap into some of the cargo that heretofore has been going all the way from Asia through the Panama Canal into Texas,” said Borossay. “We’re going to be able to pull some of that cargo back to California from Texas for these projects. It puts us back in the game because we have this heavy-lift capacity.” A self-sustaining entity, the Port of San Diego budget does not collect tax dollars. Its revenue comes from a variety of sources including commercial real estate around San Diego Bay, fees from ships using the port’s docks, wharves and cargo terminals that bring in everything from cars to wind turbines to sugar and bulk items. Established in 1962, the San Diego Unified Port District includes 34 miles of waterfront property stretching from Shelter Island to the border. Port officials manage everything from cargo and cruise terminals to hotels, restaurants, marinas, museums and 22 public parks and events along the coastline.
