World’s First.

Powering the Clean Energy Transition with the Battery Tanker

The shift to renewable energy isn’t just about generation — transporting power is just as crucial. With the world’s first Battery Tanker, Ocean Power Grid delivers clean electricity from where it’s generated to where it’s needed. This breakthrough infrastructure closes critical energy access gaps and opens new frontiers for scalable, renewable energy deployment worldwide.

Bridging Generation and Consumption

Widespread adoption of renewable energy depends on how we connect where power is generated to where it’s consumed.

At Ocean Power Grid, we offer a new solution: the world’s first Battery Tanker—designed to safely and efficiently transport large volumes of electricity across oceans.This enables flexible delivery of clean power from remote generation sites to high-demand urban areas, challenging the conventions of energy transport and accelerating the global spread of renewable energy.

Japan is home to many inhabited remote islands, most of which still rely on diesel power. Battery Tankers offer a cleaner, more economical, and stable alternative—reducing CO₂ emissions and easing the burden of fuel transport. As next-generation infrastructure, they hold strong potential to support sustainable island living and scalable clean energy delivery.

Offshore wind power in Japan’s coastal waters is a fast-growing renewable energy source. However, as generation sites move farther from shore, delivering electricity becomes a major challenge. Battery Tankers offer a flexible solution for transporting power from sea to land—serving as “mobile transmission lines” that can accelerate the full-scale deployment of offshore wind.

Global Expansion

Just like in Japan, many regions—especially island nations—face challenges due to limited grid infrastructure.Even where renewable energy is growing, lack of transport options remains a major hurdle. Battery Tankers offer a new solution for delivering sustainable electricity to these areas. With Asia-Pacific and Latin America as key starting points, we aim to deliver clean power to underserved regions globally.
