Eco-friendly High-Capacity Flow Battery for Sustainable Long-Term Energy Storage

energyPrototypeTRL 3

Imagine a battery where the energy is stored in separate tanks of liquid rather than a solid block, making it easier to scale up. To stop the liquids from mixing and wearing out, this system uses a special 'oil and water' trick to keep components separate. It's like having a fuel tank that lasts for years without needing a replacement.

Target: Heavy-duty electric fleet operator

If you are a logistics company dealing with low energy density in current flow batteries — this project developed a technology aiming for 50 Ah L-1. This allows for more energy storage in a smaller footprint for heavy transport.

Frequently asked

Quick answers

What is the estimated cost or price of this technology?

Based on available project data, specific cost per kWh or unit pricing is not provided; however, the project focuses on using non-critical materials to improve cost-effectiveness.

Can this be scaled to an industrial level?

The project uses a flowing configuration where the energy storage reservoir is separate from the reactor, which is a design inherently suited for industrial scaling.

What is the IP and licensing status?

Based on available project data, the project is in the proof-of-concept stage; specific patent or licensing agreements are not listed in the summary.

How does it integrate with existing energy systems?

It is designed as an Energy Storage System (ESS) to replace or supplement current Li-ion or Vanadium flow batteries in decarbonized energy solutions.

What is the timeline for market availability?

The project period runs from 2022-05-01 to 2025-10-31, suggesting the technology is currently in the development and prototyping phase.

Consortium

Who built it

The consortium is heavily research-driven, consisting of 6 partners across 4 countries (AT, DE, ES, PT). It is dominated by academic institutions with 4 universities and 1 research center, while industry representation is low at 17% (1 SME). This structure suggests the project is focused on high-risk, high-reward fundamental breakthroughs rather than immediate commercial rollout.
