ABS Approves First US-Made LFP Marine Battery System for Fleetzero

ABS has issued a product design assessment to Fleetzero for its Leviathan Battery Energy Storage System, marking the first US-manufactured lithium iron phosphate marine battery to receive classification approval. The system operates at up to 1,000 volts and features a modular, containerised design suited to a range of vessel types. Its first commercial deployment will come later this year, using 10 MWh of capacity as part of a vessel's conversion to hybrid-electric propulsion.

 

Details of the Approval

 

ABS has granted a significant classification milestone to Fleetzero. It issued a product design assessment for the Leviathan system. This is Fleetzero's Battery Energy Storage System for marine use. The approval marks a notable first for US manufacturing. It covers the first US-made lithium iron phosphate marine battery to be classed.

The assessment reflects a formal technical review process. ABS reviewed the Leviathan system for marine application. The approval supports its use in future projects. These are projects requiring class-verified battery technology. This validation provides assurance for potential adopters.

 

Technical Specifications

 

The system is built on a specific battery chemistry. It uses lithium iron phosphate, known as LFP chemistry. This chemistry is valued for its safety and stability. The system operates at up to 1,000 volts direct current. This high voltage supports demanding marine applications.

The system offers robust performance characteristics. It supports a depth of discharge from 2 to 98 percent. This wide range allows extensive use of its capacity. The system carries an IP67 rating for protection. This rating indicates strong resistance to dust and water ingress.

 

The Modular Design

 

The system's design emphasises flexibility. It features a modular, containerised structure. This design allows the system to be specified for different needs. It can be deployed across a range of vessel types. It can also be replaced as required over time.

This adaptability offers practical advantages for operators. Containerised systems can be integrated into varied applications. The modular approach simplifies specification and installation. It also eases replacement when maintenance is needed. This flexibility broadens the system's potential uses.

Significance for Electrification

 

The approval carries importance for maritime electrification. Class-verified battery technology builds confidence among adopters. Company representatives noted the industry faces practical electrification challenges. Verified technology plays a role in addressing these. It provides reassurance for owners and integrators.

The approval reflects rigorous technical work. ABS described the process as requiring careful review. This work is essential for bringing new solutions to market safely. Battery safety is a critical concern in marine applications. Classification approval demonstrates that these concerns have been addressed.

 

First Commercial Deployment

 

The system is set to enter service soon. Its first commercial deployment will be on the water later this year. This will demonstrate the technology in a real application. It moves the system from approval to operational use. This deployment marks an important step for the product.

The initial project has a defined scope. It will use 10 MWh of Leviathan battery capacity. This forms part of a vessel's broader conversion. The vessel is being converted to hybrid-electric propulsion. This application illustrates a practical use for the technology.

 

Industry Context and Outlook

 

The approval reflects years of development work. Company leadership described it as the result of disciplined engineering. This included close collaboration with ABS throughout. Such collaboration is central to bringing new technology to market. It combines manufacturer expertise with classification oversight.

The company frames the technology as meeting an industry need. It argues the maritime sector needs proven energy storage. This storage should use safe, scalable chemistry. The company believes the Leviathan delivers on these requirements. It is now putting the system to work immediately.
