Modular Floating Nuclear Power Barges for Low-Cost Clean Energy and Industrial Heat

energyTestedTRL 5

Imagine a small, super-safe nuclear battery floating on a barge. Instead of a giant concrete plant, this reactor uses liquid salt that can't explode or melt down, making it safe enough to put near cities. It acts like a giant power bank that kicks in when the wind stops blowing or the sun doesn't shine.

The business problem

What needed solving

Current nuclear plants are too expensive, slow to build, and carry high safety risks. Renewable energy is variable and cannot provide the high-grade heat needed for heavy industry.

The solution

What was built

A design for a Compact Molten Salt Reactor (CMSR) integrated into a modular floating barge for serial production.

Who can put this to work

Maritime & Shipping
enterprise
Target: Shipyard and Marine Engineering firms

If you are a shipyard dealing with the need for standardized green energy infrastructure — this project developed a modular Power Barge that allows for serial production. This reduces the time and cost typically associated with building nuclear plants on land.

Heavy Industry
enterprise
Target: Chemical and Fertilizer plants

If you are a chemical manufacturer dealing with high energy costs for heat — this project developed a reactor with high outlet temperatures. This allows for the efficient production of carbon-neutral hydrogen and fertilizers.

Municipal Infrastructure
mid-size
Target: City Utility Providers

If you are a city utility provider dealing with unstable renewable energy grids — this project developed a 200 MW to 800 MW power source. It provides reliable electricity, district heating, and desalination for clean water.

Frequently asked

Quick answers

How does the cost compare to traditional fossil fuels?

The Levelized Cost Of Electricity is approximately 50% of the cost of coal and 70% of the cost of gas.

What is the industrial scale of the power output?

The modular Power Barge design is capable of delivering between 200 MW and 800 MW of electricity.

What is the IP status of the technology?

The company has patented technologies and an established IPR strategy to protect the Compact Molten Salt Reactor design.

How is the safety managed to avoid regulatory roadblocks?

The reactor operates at near-atmospheric pressures and uses salt properties that prevent meltdowns or explosions, reducing the need for large emergency planning zones.

When will the technology be available for deployment?

Based on available project data, the project period runs until May 31, 2025, focusing on industrialization and commercialization.

Consortium

Who built it

The project is led by a single SME, Saltfoss Energy (Denmark), representing a 100% industry-led effort. This lean structure suggests a fast-track commercialization approach, relying on the company's own patented IP rather than academic research partners.
