Noon Energy, a US-based startup developing multi-day energy storage technology, has entered into an agreement with Sabanci Renewables to jointly deploy up to 1 gigawatt of ultra-long duration energy storage (ultra-LDES) capacity targeted at powering artificial intelligence infrastructure in the United States.

A Storage Partnership Aimed at AI's Growing Power Appetite

The joint venture pairs Noon Energy's multi-day storage technology with Sabanci Renewables' position as an established renewables platform. The combined effort is oriented toward meeting the surging electricity demand associated with AI computing operations, particularly data centers, which have placed increasing pressure on grid infrastructure and power procurement strategies across the country.

Long-duration and ultra-long duration energy storage technologies have drawn heightened interest as data center operators seek reliable, around-the-clock clean power sources that go beyond what shorter-duration battery systems — typically measured in two-to-four-hour increments — can provide. Multi-day storage, by contrast, can theoretically bridge extended periods of low renewable generation, making it a candidate for powering the kind of continuous, high-intensity loads that AI data centers represent.

Noon Energy's Technology in Focus

Noon Energy has positioned itself within the emerging ultra-LDES segment, which encompasses storage systems capable of discharging over timescales of many hours to multiple days. The company's technology is designed to address the intermittency gaps that shorter storage assets cannot economically fill, particularly in scenarios where renewable generation may be curtailed or unavailable for extended stretches.

The 1 GW target represents a substantial scale for a storage technology that, like many in the long-duration sector, is still working through commercialization. Details regarding the specific deployment timeline, project locations, or financing structure were not available in the source reports reviewed.

Sabanci Renewables' Role

Sabanci Renewables, the renewable energy arm associated with the broader Sabanci group, brings development and project execution capabilities to the arrangement. The partnership is structured as a joint development agreement, with the two companies working together to bring the ultra-LDES projects to fruition rather than one party simply supplying technology to the other.

The framing of the deal around AI infrastructure signals a deliberate effort to align storage development with one of the electricity sector's fastest-growing demand categories. Hyperscale data centers and AI-focused computing campuses have become significant drivers of new power procurement activity, prompting developers and technology providers alike to tailor their offerings to that customer segment.

Broader Context for Ultra-LDES

The ultra-long duration storage market remains in a relatively early stage compared with lithium-ion battery storage, which has achieved significant cost reductions and deployment scale over the past decade. A range of technologies — including iron-air batteries, liquid air storage, compressed gas systems, and carbon-based approaches — are competing to establish commercial viability at meaningful scale.

Regulatory and policy support in the United States, including provisions within recent federal energy legislation, has created incentives intended to accelerate long-duration storage deployment. That backdrop has encouraged a wave of startup activity and partnership announcements, though the path from agreement to operational gigawatt-scale projects involves substantial capital, permitting, and technical execution challenges.

The Noon Energy and Sabanci Renewables arrangement adds to a growing list of long-duration storage ventures targeting the AI data center market, reflecting a convergence between two of the electricity sector's most closely watched trends: the commercialization of extended-duration storage and the rapid scaling of AI-driven power demand.
