With a powertrain designed by Golden Gate Zero Emission Marine, the Sea Change is powered by Cummins’ 360 kW fuel cell and can reach speeds up to 22 knots. The fuel cells are supplied with hydrogen from storage tanks creating electricity to run the electric motors and turn the vessels propellers, generating the ferry’s movement. With the ZEF only producing water and electricity as a by-product, it’s 100% emissions free.   

The Sea Change is owned by SWITCH Maritime, a North American impact investment company working to create America’s first fleet of zero emission marine vessels. This project is also partially funded by a $3 MM grant from the California Air Resources Board, administered by the Bay Area Air Quality Management District, that comes from the California Climate Investments initiative. The Sea Change is in the final phases of construction and set to begin sea trials this year. 

The company’s alternative power solutions are set to power applications across the port ecosystem. This includes battery electric terminal tractors and six Class 8 fuel-cell powered drayage trucks that will transport goods from ships to warehouses in Southern California. In addition, Cummins is designing and building containerized hydrogen fuel cell generator systems that will supply both stationary and portable port power.
