PowerX Inc, Battery Tanker An Ocean Power Grid Project

A new way to carry electricity across the oceans

The world's first Battery Tanker to connect grids, islands, and nations.

Transport gigawatt hours of electricity across the oceans, sending surplus energy to those who need it.

There’s plenty of wind, solar, and thermal energy on Earth,

but not where people need it most.

So let’s ship it.

Creating a Battery Tanker

to bridge grids, islands, and nations.

Oceans can run deep, with seismic activity. Laying an underwater cable isn't always ideal.

The Battery Tanker can bridge energy sources across oceans, making connections that were once thought impossible.

The World's First Battery Tanker
Power Ark 100
Use Cases
The Power Ark series of ships are scalable in size and capacity. They can also be optimized for different missions. Connecting Grids, offshore wind farms, and longer distances are all within the scope of future Power Ark models.
Grid to Grid
Offshore Wind to Grid
Grid to Island
Decommissioned thermal or nuclear power plants can be retrofitted as connection ports.
It is estimated by 2060, more than 1,000 thermal power plants will be decommissioned world wide, creating many opportunities to use existing infrastructure to connect the Power Ark. Leveraging existing infrastructure greatly reduces cost of deployment.
A brighter future

The economics of the

Battery Tanker only get better

Battery densities have historically increased and battery prices have steadily decreased. As time progresses, the economics of shipping electricity will become increasingly better.
The Power Ark is designed to be mass produced and scalable, allowing for different configurations based on mission requirements
Bridging short distances can make an enormous difference.
The Power Ark can economically travel up to 300km with today's battery density. As densities increase, the Power Ark will be able to carry more power over longer distances.
There are many opportunities in the world where a short travel distance can connect independent grids. The Power Ark stores energy in DC, allowing for flexible power conversion when connected to a variety of grids.
Mission 2030
As battery densities increase and costs decrease, Battery Tanker will be able to transfer more power over longer distances more efficiently.
Battery densities are anticipated to decrease as battery technology continues to advance, which will enable the vessel to travel longer distances without frequent recharging and make the overall operation more cost-effective.
The Battery Tanker represents a transformative opportunity to establish a renewable power grid across oceans by efficiently transmitting electricity between countries. Acting as a mobile power station, Battery Tanker delivers renewable energy to geographically distant regions and enables sustainable development on a global scale.
