Palo Alto-based ultra-long-duration battery startup Noon Energy and Turkish utility Sabanci Holding's U.S. renewables arm, Sabanci Renewables, have signed a strategic agreement to co-develop up to 1 GW (100 GWh) of 100+ hour storage paired with solar and wind, aiming to deliver 24/7 clean power to AI data centers as soon as 2027.
Baseload renewables sold as a PPA
The partners will structure the sites as power purchase agreements or capacity offtake deals rather than merchant projects, bundling Sabanci Renewables' ERCOT solar capacity with Noon's reversible electrofuels batteries. Sabanci Renewables today operates and is constructing four plants totalling 790 MWdc in Texas and is targeting 3 GW of U.S. capacity within five years, so up to 1 GW of firming storage would materially shape that portfolio.
Reversible chemistry priced for AI-scale contracts
Noon's system stores energy in abundant elements like carbon and oxygen instead of lithium, allowing durations well past 100 hours. Chris Graves, Noon's CEO, framed the Sabanci pact as the commercial vehicle to prove out cent-per-kWh 24/7 renewables at gigawatt scale, while Sabanci Renewables Chief Growth Officer Murat Oguz Arcan tied the deal to AI data center growth that requires firm clean supply.
Sister-company investor unlocks the pipeline
The tie-up was catalyzed by Sabanci Climate Ventures, the sister venture arm that already sits on Noon's cap table, alongside earlier backers At One Ventures, Emerson Collective, Clean Energy Ventures, Aramco Ventures, and Prime Impact Fund. It slots neatly into the broader wave of AI-infrastructure power deals such as Meta's 1 GW Noon offtake in June, Ore Energy's $43M multi-day battery round, and Form Energy's $750M Series G.
