The World's First Commercial Hydrogen Fuel Cell Vessel
On-board Technology
ZEI Maritime Hydrogen Power System (V0)
ZEI Hydrogen Fueling Interface (V0)

Project Summary:
The Sea Change (a.k.a. Water-Go-Round) is the first hydrogen fuel cell vessel in the US and the first commercial fuel cell ferry in the world. It serves as proof that hydrogen fuel cells can be successfully utilized on commercial marine vessels and represents a global paradigm shift for the maritime industry.

The vessel is designed to carry 84 passengers at a top speed of 22 knots, with minimal noise and vibration, and emitting nothing but warm water vapor and water pure enough that the passengers onboard will be able to drink it.

360kw of H2 Fuel Cells
H2 tank array (242 kg, 250 bar, up to 2 full days operation
2x 300 kW (400 hp) shaft motors
100 kWh Li-Ion batteries
