Next-Generation Electric Energy Storage for Greener and More Efficient Shipping

transportTestedTRL 5

Imagine replacing a ship's heavy fuel tanks with a smart battery system that doesn't catch fire and lasts longer. Some parts of the system handle the steady cruising, while others act like a sprint booster for sudden power needs. It's like giving a boat a high-tech electric heart that is safer and cheaper to run than today's batteries.

The business problem

What needed solving

Traditional marine batteries are often too heavy, unsafe, or inefficient for the high power peaks and constant loads required in shipping. This limits the ability of the waterborne transport sector to fully electrify and meet climate-neutral goals.

The solution

What was built

Three energy storage solutions: solid-state batteries for constant loads, supercapacitors for power peaks, and a hybrid system. A scaled-down HIL test setup was also developed to test operational performance.

Who can put this to work

Inland Waterway Transport
mid-size
Target: Barge and river cruise operators

If you are a barge operator dealing with high fuel costs and emissions on river routes — this project developed solid-state batteries that provide safe, constant power for steady loads. This allows for a transition to electric shipping in inland waterways.

Short-Sea Shipping
enterprise
Target: Coastal freight vessel owners

If you are a vessel owner dealing with extreme power spikes during loading or adverse sea conditions — this project developed supercapacitors that shave power peaks. This prevents battery strain and improves overall energy efficiency.

Marine Engineering
any
Target: Shipyard and vessel designers

If you are a ship designer dealing with the trade-off between energy capacity and power bursts — this project developed a hybrid system combining solid-state batteries and supercapacitors. This provides both high energy and high power density in one package.

Frequently asked

Quick answers

What is the expected cost or price of these systems?

Based on available project data, the project aims to create solutions that are cost-competitive compared to traditional batteries, though specific pricing is not provided.

At what industrial scale are these technologies currently available?

The project is demonstrating three energy storage solutions at TRL 5. A roadmap is being defined for full-scale onboard demonstrators of two systems by 2027.

How is the IP or licensing handled for these batteries?

Based on available project data, there is no specific information regarding the IP or licensing model for the developed technologies.

How do these systems integrate into existing ship designs?

The project uses HIL simulation and digital twins to test operational performance. It also includes a safety assessment and checklist for integrating the systems on board.

What is the timeline for seeing these on real ships?

The project runs until 2026-01-31, with a roadmap targeting full-scale onboard demonstrators by 2027.

Consortium

Who built it

The consortium is well-balanced for commercialization, featuring 14 partners across 8 countries. With an industry ratio of 43% (6 companies, including 3 SMEs), there is a strong link between the 3 universities and 5 research centers and the actual market. This structure suggests the technology is being developed with direct input from the maritime sector to ensure practical applicability.
