Perfekt’s Akuna batteries are a new generation of non-vanadium flow batteries specifically engineered for long-duration energy storage in AI data centres and high-performance computing environments.

Unlike conventional lithium-ion systems designed for short discharge windows, Akuna’s architecture is optimised for 12–18 hour discharge cycles, enabling true 24/7 hyperscale operations powered by renewables. This makes the system structurally aligned with solar PV, solving the intermittency problem without relying on fossil baseload or oversized grid connections.

A defining characteristic of the Akuna battery is its vanadium-free and graphite-free chemistry, eliminating key geopolitical and supply-chain risks that affect traditional vanadium redox flow batteries.

The electrolyte is water-based, non-toxic, and non-flammable, meaning there is no thermal runaway risk and no hydrogen generation, allowing deployment in dense urban or mission-critical environments without complex fire-suppression systems. This intrinsic safety profile significantly reduces insurance costs and operational risk for hyperscale operators.

Economically, the platform is positioned as a disruptive alternative within long-duration storage. The electrolyte is significantly cheaper than VRFB systems, materially reducing both CAPEX and OPEX. Moreover, increasing storage capacity primarily requires enlarging electrolyte volume rather than duplicating full power stacks, allowing highly competitive cost scaling for multi-hundred-MWh installations. This makes the technology particularly suitable for 100 MW-class data centres seeking energy autonomy and other high-energy consumption applications.

The systems are engineered with a possibility of dual advantage: energy storage and cooling infrastructure, particularly important for high-performance computing.

Akuna platform is designed for longevity and circularity. With an expected 15–20 year lifespan, the system experiences minimal capacity degradation over time. The electrolyte is easily recyclable, supporting a circular operational model and long-term sustainability objectives. Together, these characteristics position the Akuna battery as not just an energy storage device, but as a foundational infrastructure layer for various energy applications, including AI-era energy and thermal resilience.
