Problem
The increasing reliance on renewable energy sources like solar and wind necessitates long-duration energy storage solutions to address intermittency and ensure grid stability. Existing energy storage technologies often rely on scarce materials, have limited lifecycles, or pose safety and environmental risks. This creates a need for sustainable, safe, and cost-effective energy storage options that can provide reliable power over extended periods.
Solution
Flux XII develops flow battery technology utilizing synthetically engineered organic molecules derived from abundant elements, enabling a sustainable and domestically sourced energy storage solution. Their flow batteries use a pH-neutral water-based electrolyte, enhancing safety and reducing environmental impact. The technology is designed for long-duration energy storage, addressing the intermittency challenges of renewable energy sources and providing grid resilience. Flux XII's organic redox materials, combined with advanced ion-exchange membranes, contribute to enhanced energy density, cycling stability, and energy efficiency compared to existing flow battery technologies.
Target Audience
Flux XII targets utilities, independent system operators (ISOs), and renewable energy project developers seeking long-duration energy storage solutions for grid stabilization, as well as commercial and industrial customers looking to optimize energy management and increase resilience.
