California provides $3m grant to hydrogen ferry in San Francisco

The Water-Go-Round would carry 84 passengers without emitting any carbon dioxide or health-threatening pollutants

The Big Zero report

The California Air Resources Board (CARB) has announced a $3 million (£2.3m) grant to help build a hydrogen fuel cell ferry in San Francisco.

The Golden Gate Zero Emission Marine project claims the ferry would be the first of its kind in the US.

The planned vessel, named Water-Go-Round, would carry 84 passengers around the Bay Area without emitting any carbon dioxide or health-threatening pollutants.

The planned ferry’s onboard storage tanks would carry enough hydrogen to last about two days before being refuelled by a truck at port, with lithium-ion batteries and electric motors providing additional power.

Ferry operator Red and White Fleet will operate the vessel for the first three months and plans to eventually purchase it.

The clean ship’s developers say although ferries contribute a relatively low proportion of total maritime emissions, they typically operate around densely populated areas, where emissions are known to pose significant health threats.

Construction is expected to start in Autumn 2018 and the vessel is expected to become operational roughly a year later.
