tugboat called the eWolf will slash greenhouse gas emissions for the port and its neighbors in Barrio Logan and National City by running on electricity instead of diesel fuel.. “This is where the world is going and we want to be a pioneer in this technology.”and two electric motors. The tug has bollard pull of about 70 short-tons, which is comparable to its diesel counterpart at the Port of San Diego, and two small generators for emergency use.
The charging station is designed to allow vessels to recharge quickly and reduce peak loads on the energy grid. It will be built by a subcontractor hired by Crowley, with San Diego Gas & Electric helping with interconnections. Currently under construction in Alabama, the all-electric tugboat is expected to arrive at the Port of San Diego in the first quarter of next year. Jackson said the eWolf will replace one of two diesel-powered tugs Crowley operates at the port. That will eliminate the consumption of more than 30,000 gallons of diesel fuel per year.
Over the first 10 years of use, the electric tugboat is expected to reduce about 3,100 metric tons of carbon dioxide from the port and its surrounding areas.
