LEVIATHAN MODULAR ENERGY STORAGE SYSTEM
The safest and most efficient marine battery system in the world.
-
Regardless of the size of the vessel, or space on board, we create custom solutions to accomplish the mission
-
Leviathan batteries typically pack double the power, for half the price when compared to other marine solutions
-
Extend the live of your vessel and propulsion system with custom hybridized solutions. Connect with our team to day to explore how you can get Leviathian onboard.
-
Fleetzero’s Leviathan batteries enable you to unlock both energy and financial efficiency. Allowing you to decarbonize, without the green premium. In nearly every case, it pays to be powered by Fleetzero.
MARINE BATTERY CONTAINER
Fleetzero’s proprietary design delivers 3.8 MWh of energy in a footprint 25% of the size of a standard container. It is engineered to empower vessels on even the longest range missions.
-
Efficient design and scalability empowers your vessel to cross the Pacific Ocean and back, all on a single charge.
-
Our company is comprised of U.S. Navy veterans, seafarers, and other industry experts. We are building the world’s safest marine battery solutions. None of our products will be integrated into a ship that we personally would not sail on.
-
Anyone who has served in the maritime space understands having the right crew means everything when you are on the water. From concept to commissioning, our team of engineers, mariners, finance and more seamlessly integrate themselves with your team to ensure projects arrive ahead of schedule and beat benchmarks. Think of it as white glove service with calloused hands.

MODULAR PROPULSION
Modularity reduces ship construction costs and is enabled by an electric propulsion system. Fleetzero’s Leviathan modular energy storage system is designed to scale from the smallest support vessel to the largest ships on the water today. Nearly every project we undertake results in a payback period of under six years, and many are positive within the first two. 
MODULAR HULL
Replication equates to lower construction costs. Traditional shipbuilding is labor-intensive. Fleetzero is pioneering modular hull construction to lower costs and increase shipyard output.
