Non-Lithium LDES Technologies Powering AI Data Centres
The exponential growth of artificial intelligence has placed unprecedented demands on data centre infrastructure, prompting developers to seek reliable, long-duration energy storage (LDES) alternatives to traditional lithium-ion batteries. Several innovative non-lithium technologies are now stepping up to address these critical power challenges.
Massive Flow Battery Deployments
In a landmark move for the vanadium redox flow battery (VRFB) sector, Invinity Energy Systems has secured an EPC contract to build a massive 2.1GWh VRFB for a data centre in Switzerland. Developed by FlexBase, this project, initially announced in June and confirmed in August, stands as the largest flow battery project announced globally to date. Flow batteries are highly favored for their decoupled power and energy capacity, making them exceptionally safe and ideal for long-duration applications.
Iron-Air and CO2 Solutions
Meanwhile, Form Energy is targeting the AI data centre market with its breakthrough iron-air battery technology. The company announced a major agreement to supply 12GWh of battery energy storage to AI data centre developer Crusoe. The system boasts an impressive 100-hour duration, providing a highly favorable, cost-effective, and safe alternative to onsite fossil fuel storage for extended outage coverage.
Addressing mechanical storage efficiency challenges, Energy Dome has introduced a novel solution pairing its CO2 Battery compressed-gas energy storage system with on-site gas turbines. By utilizing waste heat from the turbines, the integrated system significantly improves overall round-trip efficiency.
These diverse non-lithium technologies highlight a critical shift in data centre power management, prioritizing ultra-long duration, safety, and grid resilience over traditional short-duration solutions.
As AI workloads continue to surge globally, the integration of these advanced LDES technologies will be crucial in ensuring uninterrupted, sustainable, and resilient power for the expanding digital economy.
