Meta Platforms and Noon Energy finalized a reservation agreement for up to 1 GW / 100 GWh of energy storage capacity, marking a strategic investment in ultra-long-duration energy storage to support AI infrastructure. The collaboration will commence with a 25 MW / 2.5 GWh pilot project scheduled for completion by 2028, followed by full-scale delivery under a 100 GWh supply contract. Noon Energy’s technology utilizes a reversible solid oxide fuel cell that stores energy in carbon-based media, enabling multi-day storage with over 100 hours of capacity demonstrated in a containerized pilot. The system’s reliance on abundant elements like carbon and oxygen reduces critical material usage to approximately 1% of that in traditional lithium-ion batteries, addressing lithium supply chain volatility. For Meta, the 100-plus hour duration provides grid resilience beyond the 4-hour window of lithium-ion systems, aligning with the energy demands of hyperscale data centers.
