Leviathan

Leviathan is the world’s most energy-dense battery for marine.

Leviathan modules stacked into 3 towers

  • True cell-to-cell thermal runaway and fire prevention are provided by Fleetzero’s proprietary passive fire prevention system.

    • 240 Wh/l Volumetric

    • 142 Wh/kg Gravimetric

    Densities are provided at the DC system level (module + string + pack).

  • Leviathan modules are scalable for systems sizes from 200 kWh to hundreds of Megawatt-hours of energy storage.

  • Optimized for high-energy and zero-emission operation of large vessels.

    Configurable for high-power applications with high C-rates when installed with our liquid cooling system for use in peak-shaving operations in large vessels or primary or backup power for tugs, work boats, CTV, and ferries.

  • Designed by mariners and engineers from the world’s best automotive EV companies, Leviathan incorporates the best automotive EV technology but is fundamentally built for the unique challenges and requirements at sea.

    Designed and tested in accordance with ABS, DNV, RINA, Lloyds, and ClassNK rules.

  • Leviathan contains no nickel, manganese, or cobalt, making it one of the most sustainable batteries in the world. We chose our battery chemistry to minimize the impact of mining and sourcing raw materials.
