The city of Yokohama’s Port and Harbor Bureau has stopped to operate the parts of its self-sustained hydrogen fuel-cell system that use hydrogen for 10th-year verifications.
For the time being, Yokohama will supply Yokohama Port International Cargo Center (Y-CC) with electricity generated by solar power and, at the same time, continue to promote next-generation energy resources to make the Port of Yokohama carbon neutral.
Called H2One and produced by Toshiba Energy Systems and Solutions, a Kawasaki-based affiliate of Toshiba, the self-sustained hydrogen fuel-cell system stores CO2-free hydrogen electrolytically generated from tap water and generates electricity from it. In times of natural disaster, the system, which was introduced in 2015 for the first time at a public office in Japan, operates on a self-sustained basis without depending on grid power to secure sufficient electricity for information gathering and other activities.
It has now been verified the self-sustained hydrogen fuel-cell system can boot up automatically with stored hydrogen even when a natural disaster occurs at island wharves within ports. Even if the system is disconnected from and cannot access grid power, or adverse weather conditions keep solar power generators from working, it can still supply a sufficient amount of electricity and maintain communication capabilities for a period of three days or so.
