US-based Noon Energy has demonstrated successful long-term operation of its scaled-up ultra-long-duration energy storage (ultra-LDES) system that provides a groundbreaking 100-plus hours of energy storage capacity—touted as the missing link to clean, reliable electricity 24/7, year-round.
The reversible solid oxide fuel cell battery is the first fully containerised, modular ultra-LDES system successfully operated for thousands of hours, with storage of over 200 hours of energy capacity, marking an incredible milestone in the energy industry.

Noon Energy’s system is a breakthrough in low-cost ultra-LDES. It enables inexpensive energy sources, including intermittent renewables, to become reliable and economical— delivering power 24 hours a day, 365 days of the year, regardless of power shortages or day-to-day/seasonal shifts in sun and wind.
When co-located with VRE sources, Noon Energy’s ultra-LDES system can store 100-plus hours of energy for multi-day capacity management, and integrate with short-duration batteries to smooth power delivery and cover immediate, high-intensity needs. Today, most renewable energy is stored in lithium-ion batteries that are sized for two to 10 hours.
Combining this with a Noon battery, which has 50 times that energy capacity, is the optimal configuration for cost and performance.
Noon Energy co-founder and CEO Chris Graves said, “We are excited to have commissioned our multi-module demonstration system and demonstrated its lifetime, thanks to the excellent work of our incredible engineering team. This is a key milestone for our breakthrough technology’s scale-up.
“We have also built an even larger, commercial-scale system, being commissioned soon with more details to come. Noon’s unique energy storage system enables low-cost, clean firm power for hyperscalers and other industrial load growth, which form an important part of our large customer pipeline.”
