Hydrogen Fuel Cell Project at Honolulu Harbor
The generator is used to power up to 10 refrigerated containers at a time.
Hydrogen fuel cells have a long track record of supplying efficient, clean power for a wide range of applications, including forklifts, emergency backup systems, and vehicles. An analysis by Sandia and DOE showed that due to fluctuating loads in maritime auxiliary power applications, a hydrogen fuel cell, which follows the load, is more energy efficient than a diesel engine. A hydrogen fuel cell only supplies power when it is needed. The Maritime Hydrogen Fuel Cell Project is a demonstration of this analysis in a commercial port setting.
Hosting the technology fits in with Young Brothers’ core value of environmental stewardship, Young Brothers President Glenn Hong, shown here at the Honolulu Harbor facility.
The project began its field trials in August 2015 with a six-month deployment hosted by Young Brothers Ltd., a subsidiary of Foss Maritime Co., at its facility in the Honolulu Harbor. The U.S. Department of Energy’s Fuel Cell Technologies Office and the U.S. Department of Transportation’s Maritime Administration are cofunding the pilot. The pilot hydrogen fuel cell unit will replace a diesel generator currently used to provide power for refrigerated containers on land and on transport barges.
Hydrogenics Corp. designed and manufactured a containerized 100-kilowatt hydrogen fuel cell unit, which includes the fuel cell engine, a hydrogen storage system, and power-conversion equipment. Built into a standard shipping container, the unit has an outward appearance and functionality similar to maritime diesel generators that are currently in use.

As the primary interisland shipper of goods within Hawaii, Young Brothers Ltd. has a strong environmental and financial interest in the project. After initially using the hydrogen fuel cell unit on land, Young Brothers Ltd. will deploy the unit to power refrigerated containers onboard barges traveling between the Honolulu and Kahului harbors.
During the six-month deployment, performance feedback and data will be collected to determine the environmental, energy, and cost savings from the hydrogen fuel cell unit. Sandia will analyze the operational, safety, and cost performance data to develop a business case for using hydrogen fuel cells at other commercial ports. In addition, the safety aspects and feedback from the unit’s design and operation may guide regulators toward formal codes and standards for hydrogen and fuel cells in maritime applications, thereby increasing the likelihood of this clean-energy technology being adopted for maritime use.
