The Sea Change ferry is almost completed and ready to operate in the San Francisco Bay in the third quarter of this year. It runs on compressed hydrogen gas flowing through a fuel cell. The ferry will be the first of its kind to operate for two days on one tank.
Sea Change is a 22 m high passenger ferry that can carry 84 passengers at a time. Twin 300 kW (400 horsepower) electric motors will accelerate it to a top speed of 22 knots (41 km / h).
Sea Change will transport about 246 kg of hydrogen gas compressed at 250 bar (~ 1,633 kg per 0.4 cm²) in its tanks.
A large fuel cell converts this hydrogen into electricity.
The ferry is 98% ready and will be launched in the third quarter of 2021.
