Founded with a vision to change how the world consumes and transfers renewable energy, PowerX today announces its business to innovate power storage and transmission by developing a Power Transfer Vessel to carry electricity from offshore wind farms to shore and also by building a large-scale battery packing facility in Japan to produce EV fast-charging, grid, and marine batteries.

The Japanese government targets for renewable energy to generate 36-38% of the country's power production in fiscal 2030, a major upgrade from its previous plan of 22-24%. This will require a boost of offshore wind power from the current 20MW to 10GW by fiscal 2030 and to 30-45GW by fiscal 2040. Japan is surrounded by deep coastal waters, which limit the potential range for setting up offshore wind farms. PowerX was founded with a vision to change how the world consumes and transfers renewable energy by providing a unique solution that can lift the restriction on power generation location, which will allow a greater flexibility for offshore wind farm locations, especially for an island country like Japan. By driving innovation in the way the world storages and transports energy, PowerX aims to enable an unprecedented energy transmission between any two ports on the planet, and thus accelerates the adoption of renewable energy.

PowerX will design and build an automated Power Transfer Vessel with a massive battery payload that is integrated with the ship's controls to transport offshore wind power to shore.

An undersea power cable typically requires expensive construction that comes with substantial environmental impacts.

Comparatively, the Power Transfer Vessel stands out as it is resilient to natural disasters, requires less time and cost for development, leaves minimal impact on the environment, and therefore is able to expand the potential of offshore wind power significantly.

The very first model of the Power ARK series, "Power ARK 100" is a 100TEU trimaran specially designed for transferring renewable energy in Japan's coastal waters. Upon its completion in 2025, Power ARK 100 will carry 100 grid batteries, hence 200MWh of power (equivalent to the total electricity consumption by 22,000 Japanese households in a day (*2)). The vessel can travel up to 300km when running only on electricity and will be able to unlock long-distance, intercontinental clean power transmission when it is powered by both electricity and sustainable biodiesel fuels.

To realize its vision, PowerX will also be building a giga-scale battery assembly facility in Japan to mass-produce batteries for the Power Transfer Vessel. With an acceleration toward decarbonization across the globe, the demand for large energy storage is soaring. Off-the-shelf battery cells will be packaged based on the use case, which includes EV fast-charging, grid, and marine batteries. The factory's annual production capacity will achieve 1GWh by 2024, and will eventually reach 5GWh by 2028. Productions lines will be automated to mass-produce at a low cost.
