Fuel Cell

Fuel cells convert hydrogen and oxygen into electricity and heat and emit only pure water. Because hydrogen fuel cells have zero noise and no moving parts they create no sound or vibration both on board and in marine ecosystems.​


Multi-Megawatt (MW) Fuel cells are currently being used to generate power in stationary applications with >1MW systems being used in port marine environments for over a decade. In maritime shipping applications, fuel cells have been used in seagoing vessels, including passenger vessels and submarines, for over 30 years. Source: Zestas


What is a Battery Management System (BMS)?

On a ship, a Battery Management System (BMS) is an integrated control and monitoring software which continually ensures the safe operation of a battery propulsion and/or storage system on board.


BMS software has large bandwidth and uses an ethernet connection with remote update capability and protocols to mitigate packet loss.


BMS carry out the following services:


• Ensures smooth and safe system start-up
• Provides current control to ensure the optimal charge/discharge rate for battery longevity
• Alarms and warnings including early identification of potential points of failure, hidden failures and failure prediction
• Remote monitoring and reporting of battery performance to inform maintenance


Redundancy is provided using direct emergency stop controls for the crew, redundant power supplies for each string, Redundant Management Software and remote monitoring for onshore investigation of anomalies by the service team.
