SeaGreen Battery Energy Storage System

for Marine Applications

Modern marine power systems require solutions to meet the industry’s drive towards decarbonization while still meeting challenging performance and class society criteria. These requirements challenge the marine industry to reduce emissions and improve fuel efficiency.


Vessels are increasingly turning to hybrid solutions, integrating stored energy into the ship’s power network to reduce dependence on fuel-burning power supplies, like diesel gensets.

Working towards a cleaner maritime environment

SeaGreen Energy Storage is particularly suited to vessels with variable operating profiles and power loads to avoid over-sizing the power network just for peak load, with options for both new ships or vessel upgrades to help comply with EEXI. SeaGreen Energy Storage can even enable ‘engines-off’ functionality for ‘clean ship’ operation in ports and docks.

General Electric

GE uses its deep experience of cost-effective, energy-efficient ship’s power and propulsion networks:

  • Provide a simple, integrated, scalable power and energy system
  • Manage energy sources according to load demand
  • AC or DC architecture options
  • Applications in all vessel types requiring cycling operations-Integrated or modular containerized options

SeaGreen BESS can be configured to operate in any or all of these five operating modes.

Some modes can be selected in parallel

  • Such as dynamic support and UPS.
  • Energy storage options tailored to suit the level and duration of power required.
  • Batteries or options for other energy store devices, like supercapacitors or fuel cells.
  • Option for land-based integration testing at full scale and load.

Seajet Podded Propulsion

GE’s SEAJET podded propulsion system is the ideal choice of electric propulsion for applications where maneuverability, efficiency or space constraints are very important. The electric motor is housed in the hull-mounted pod under the ship and directly connected to the propeller, freeing up cargo and operational space in the ship.  Through system efficiency, total fuel consumption and exhaust emissions are reduced.

Shore Power Connections

Regulation on pollution, emissions and noise in ports is becoming more and more stringent.  The resulting requirement for port electrification and higher return on existing assets puts greater demand on ageing infrastructure and increased requirement for use of alternative clean energy supplies.
