Developed by PowerX, the new electric ship promises to be the beginning of a journey that will link sustainable maritime navigation with clean energy.

The future of sustainable maritime shipping is about to become a reality, thanks to innovative Japanese startup PowerX. With the aim of solving the challenges faced by geographically disadvantaged regions, PowerX presents the revolutionary electric ship "X", a giant vessel powered by propulsion electrical and powered by state-of-the-art batteries. This ship was designed to function as a mobile power plant, capable of storing and transporting clean energy throughout the sea, without the need for fossil fuels and without emitting pollutants.

Connecting regions with clean energy

The electric vessel “X” plays a crucial role in connecting wind farms and, in particular, remote islands.

In some areas, the installation of underground cables becomes unfeasible due to seismic activity and water depth.

As a result, these regions, which have an abundance of clean energy, can now share part of their production with less favored locations.

Characteristics of the electric ship “X”

With an impressive 140 meters in length, the electric ship “X” has a range of up to 300 kilometers, which is more than enough to navigate between nearby islands.

The vessel is equipped with 96 LFP batteries, allowing the storage of up to 241 MWh of energy.

In addition, PowerX points out that the design of its marine batteries is highly scalable, which means that in the future the ship will be able to incorporate even more units.

While it's been optimized for short trips, PowerX CEO Masahiro Ito says that as costs come down, the company could add more batteries to make long-distance travel possible.

PowerX plans to complete construction of the ship's first unit by 2025 and the first sea trials are expected to begin in 2026.

The company has already signed an agreement in Yokohama, Japan, to turn this concept into reality and decarbonize the city's ports.

The ocean clean energy network

PowerX's vision is to create an ocean clean energy grid, powered by the "X" electric ship.

To achieve this ambitious goal, the startup plans to establish its first mega battery factory in Japan.

This factory will have an annual production capacity of 5 GWh and will be dedicated to the manufacture of marine batteries, domestic batteries and ultra-fast chargers of up to 240 kW, all powered by renewable energy.

With this initiative, PowerX hopes to make this vision a reality and promote the transition to more sustainable maritime navigation with the help of its electric vessel.
