Charting a cleaner feature with electric power and propulsion



May 23 ------ BAE Systems is stepping up efforts to help marine operators get to a zero-emission future with electric power and propulsion technology. As explained, the technology isn’t new as it has been powering cars and buses for years. However, with the rise in planet-warming greenhouse gases, it’s now making its way to the open water and creating a new wave of clean transportation. As vessel operators see the environmental benefits, many are making the move to adopt cleaner power sources. BAE Systems said it is ready “to turn the tide on emissions”. The company is taking its expertise in electric power and propulsion systems in the transit bus industry to the shipyard, helping operators make the switch from a combustion engine to electric or fuel cell power and propulsion for the vessels they build.


BAE Systems is using its HybriGen power and propulsion system to make it all possible. The system builds on the company’s core technology that today is powering more than 12,000 buses around the world. It promises not only to cut emissions, but to create a smoother ride for passengers and help operators save on fuel and maintenance costs, according to BAE Systems. One of the first to make the jump to the HybriGen system was the Red & White Fleet. The sightseeing company in San Francisco Bay is on the path to a greener future with its newest vessel Enhydra, which has been operating on electric-hybrid technology since 2018. Since then, the 128-foot excursion vessel has saved roughly 35 per cent of its fuel, only needing to operate its combustion engine part of the time.


Now others are also starting to take notice of this technology. On the US West Coast, Kitsap Transit is using an electric-hybrid system for its passenger ferry, Waterman, which operates out of Washington State’s Port Orchard. In San Francisco, Call of the Sea is using the technology to power a 132-foot wooden tall ship that teaches young people about maritime history while promoting sea stewardship. Just across the bay, the 70-foot Water-Go-Round passenger catamaran is expected to launch on its maiden voyage later this year with a combination of hydrogen fuel cells and lithium-ion batteries to drive its electric propulsion motors.


BAE Systems technology is also providing three vessels on the East Coast with complete electric power. Harbor Harvest is using the system on their vessel Captain Ben Moore to create a new and sustainable form of short sea shipping. The environmentally friendly boat hauls locally made products and other cargo between Connecticut and New York on the Long Island Sound. Built by New York-based Derecktor Shipyards, the technology is also helping the Spirit of the Sound and CUNY I conduct research along the coastline.


“As the pressure to get to zero emissions grows, there will be more vessels in need of clean technology,” BAE Systems said. “It’s an investment that goes beyond maturing technology. It will help to shape a new vision for the future of marine transportation – one that creates cleaner harbors and waterways in the places where we live, work, and visit.”
