Problem
The intermittency of renewable energy sources like solar and wind necessitates cost-effective and durable energy storage solutions for grid stabilization and reliable power supply. Traditional energy storage systems often rely on expensive materials, complex designs, and have limited lifespans, hindering widespread adoption.
Solution
Unbound Potential is developing membrane-less flow batteries that utilize immiscible liquids and water-based electrolytes to provide a simplified and scalable energy storage solution. By eliminating the need for membranes and cell stacks, the system reduces complexity and cost while enhancing safety through the use of non-flammable, water-based electrolytes. The design prioritizes durability, enabling over 20,000 cycles, making it suitable for long-duration stationary energy storage applications. This technology aims to provide a more sustainable and affordable alternative to conventional redox flow batteries, reducing the carbon footprint by 30%.
Target Audience
Early adopters include SMEs with local PV production, such as supermarkets and sports facilities, seeking to optimize energy consumption, and energy-sensitive businesses like data centers and logistics distribution centers seeking backup power solutions. At scale, the target audience expands to industrial facilities with local PV production, off-grid applications, and energy traders/producers needing grid stabilization and congestion management solutions.
