Meta Platforms Inc. has entered into a significant reservation agreement with Noon Energy to secure up to 100 gigawatt-hours (GWh) of ultra-long-duration energy storage capacity. Announced on April 21, 2026, the deal represents one of the largest single commitments to long-duration storage technology to date. The agreement specifies a power capacity of 1 gigawatt (GW), designed to provide reliable, carbon-free electricity for Meta’s expanding network of artificial intelligence data centers.
The partnership focuses on Noon Energy’s proprietary carbon-oxygen battery technology, which is engineered to store energy for days or weeks rather than hours. Unlike conventional lithium-ion batteries that typically provide four to six hours of discharge, Noon’s system utilizes a reversible electrochemical reaction involving carbon dioxide and solid carbon. This approach allows for high energy density at a lower cost per kilowatt-hour, making it suitable for the massive energy requirements of generative AI training and inference operations.
Meta’s decision to invest in ultra-long-duration storage aligns with its broader corporate sustainability goals. Since 2020, the company has maintained net-zero emissions for its global operations and has been one of the world’s largest corporate buyers of renewable energy. However, the intermittent nature of wind and solar power presents challenges for data centers that require constant uptime. By integrating Noon Energy’s storage solutions, Meta aims to bridge the gap during periods of low renewable generation, moving closer to 24/7 clean energy matching for its infrastructure.
Financial terms of the reservation agreement were not disclosed, but the scale of the 100 GWh commitment underscores the intensifying energy demands of the technology sector. Meta has significantly increased its capital expenditure in recent years to build out AI-ready data centers, which utilize high-performance GPUs that consume substantially more power than traditional server hardware. Chris Janzen, Meta’s Vice President of Infrastructure, stated that securing long-term energy storage is a critical component of the company’s strategy to ensure operational resilience while meeting environmental targets.
Noon Energy, led by CEO Chris Graves, will deploy the storage capacity in phases as Meta’s new data center projects come online. The technology is expected to play a pivotal role in Meta’s transition toward a more stable and sustainable power grid. This agreement follows several other energy-related initiatives by Meta, including investments in geothermal energy and advanced nuclear modular reactors, as the company seeks to diversify its energy portfolio to support its long-term AI roadmap.
