Maritime BESS containerised solutions for both retrofit and newbuilt vessels

IMO (international maritime organization) has adopted mandatory measures to reduce emissions of greenhouse gases from international shipping, under IMO's pollution prevention treaty (MARPOL) - the Energy Efficiency Design Index (EEDI) mandatory for new ships, and the Ship Energy Efficiency Management Plan (SEEMP).
MEPC 74 (May 2019) adopted on Invitation to Member States to encourage voluntary cooperation between the port and shipping sectors to contribute to reducing GHG emissions from ships. This could include regulatory, technical, operational and economic actions, such as the provision of: Onshore Power Supply (preferably from renewable sources); safe and efficient bunkering of alternative low-carbon and zero-carbon fuels; incentives promoting sustainable low-carbon and zero-carbon shipping; and support for the optimization of port calls including facilitation of just-in-time arrival of ships.
The Global Industry Alliance to support low carbon shipping (GIA), operating under the auspices of IMO’s GloMEEP project, has recognized the key role of ports in the decarbonization of shipping. In particular, just-in-time (JIT) operation of ships has a potential to reduce emissions. The GIA has been gathering experience from ports that have successfully (or unsuccessfully) implemented JIT; has been analysing barriers; and has been studying concrete measures for removal of these barriers to large-scale uptake of JIT.
Is zero-carbon shipping going to become a reality?
In the initial IMO strategy, there is a clear ambition to pursue efforts towards phasing out GHG emissions from international shipping entirely, by the end of this century. This has to become a reality.
As United Nations Secretary-General Antonio Guterres has said, “We need to put the brake on deadly greenhouse gas emissions and drive climate action…. The world is counting on all of us to rise to the challenge before it’s too late”. Research and development will be crucial, as the targets agreed in the IMO initial strategy will not be met using fossil fuels. There is a need to make zero-carbon ships more attractive and to direct investments towards innovative sustainable technologies and alternative fuels. 

​What is a maritime BESS containerized solution?
Containerized energy storage solution is a complete, self-contained battery solution for a large-scale marine energy storage. The batteries and all control, interface, and auxiliary equipment are delivered in a single standard shipping container for simple installation on board any vessel.

The standard maritime BESS container delivery includes

• Batteries
• Power converters
• Transformer
• Energy storage control system
• liquid cooling & ventilation
• Fire detection

 
How does maritime BESS container work?
The maritime BESS stores energy when demand is low, and delivers it back when demand increases, enhancing the performance of the vessel’s power plant. The flow of energy is controlled by dynamic Energy Storage Control System. It enables several new modes of power plant operation which improve responsiveness, reliability, safety, and fuel consumption.
 
What are the benefits of maritime BESS container?

• Peak Shaving

Level power seen by engines and offset need to start new engines. Benefits include reduced fuel consumption and engine maintenance.

• Enhanced dynamic performance

Instant power in support of running engines. Benefits include reduced fuel consumption and enabler for "slower" sources like LNG and fuel cells.

• Spinning reserve

Backup power to running generators. Benefits include improved safety and reduced fuel consumption and engine maintenance.
