Powering affordable zero-emission shipping.

Fleetzero’s battery technology is making affordable zero-emission ocean freight a reality

Watch - Bill Gates & Fleetzero's founders discussing an early Leviathan prototype.

INTRODUCING

Leviathan ESS

Four Leviathan Battery Modules

The world’s most advanced marine battery.

Hybridizing with Leviathan allows ships of any size to economically reduce emissions. Once fitted, owners can expand the Leviathan system to eliminate emissions over time.

Zero Port Emissions

Hybridizing auxiliary vessel electrical loads with the Leviathan battery system allows ships to operate with zero emissions in port or at anchor while reducing emissions at sea, complying with cold-ironing regulations. Typical projects pay for themselves in fuel and maintenance savings.

Zero Coastal Emissions

Pairing a shaft power take-off/take-in (PTOI) with the Leviathan system allows vessels to operate with zero emissions during maneuvering and short sea operations, such as California’s CARB-regulated 24-mile zone and other environmentally protected areas. These hybrid systems increase maneuvering reliability while also eliminating port emissions.

Zero Emissions Everywhere

Vessels retrofitted for zero coastal emissions can extend their zero-emission range to thousands of miles without sacrificing cargo capacity. This is only possible with the incredible energy density of the Leviathan battery system.

In the News

A single voyage of a Fleetzero ship can prevent as much CO2 as planting 92,577 trees and letting them grow for a decade.

Based on the typical fuel consumption of a panamax containership of 63,000 gal/day fuel across the Pacific on a one-way voyage. CO2 savings converted via www.epa.gov/energy/greenhouse-gases-equivalencies-calculator
