What are electrified transportation options for port operations?
Among emerging options: • Alternative Marine Power —also known as cold ironing, shore power or hoteling— one of the methods to control ship emissions while a ship is in port is to use shore-supplied electricity to run the ship’s lights, refrigeration, heating, air conditioning and hot water. The Port of Seattle has been plugging in docked cruise ships since 2005. Seattle City Light worked closely with the Port and the cruise lines, and have electric service agreements in place that ensure the connection and use of shore power goes smoothly. Hoteling provides phenomenal pollution and oil use reductions. The Puget Sound Clean Air Agency calculates that just eight hours of hoteling cuts on-board oil burning by 2.85 metric tons. Cruise ship air emissions are reduced by about 30 percent. The reduction in emissions is equal to taking 1,100 cars of the road for a full year.35 Cold ironing is less appropriate at this point for container and cargo ships that call at NW Ports until this technolo
