<p><a href="https://www.noon.energy/">Noon Energy’s</a> tests and demonstrations for its scaled-up <a href="https://solarbuildermag.com/energy-storage/new-long-term-ldes-forecast-now-available/">ultra-long-duration energy storage (ultra-LDES) system</a> proved successful, the Palo Alto, California-based company announced Jan. 21.</p>
<p>Touted as “the missing link” to 24/7 reliable renewable energy, the system is the world’s first containerized and modular ultra-LDES system sporting a reversible solid oxide fuel cell battery. The system has successfully operated for “thousands of hours,” the company says, and has an energy storage capacity of more than 200 hours.</p>
<p>“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,” says Chris Graves, co-founder and CEO of Noon Energy. “We have also built an even larger, commercial scale system, being commissioned soon with more details to come. </p>
<p>“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.”</p>

<p>The ultra-LDES system is a “breakthrough” in low-cost long-term energy storage, the company says. The system’s storage capacity allows less expensive energy sources like intermittent renewables to become economically viable, delivering reliable power year-round and around the clock.</p>
<p>The system sports a discharge duration of more than 100 hours, allowing for a “constant, multi-day stream of power” and making the system useful in critical applications. Additionally, the system is anywhere between 20 and 200 times smaller than other storage systems like lithium-ion BESS systems and flow batteries.</p>
<p>Supported by the <a href="https://www.energy.ca.gov/">California Energy Commission</a>, the demo of Noon Energy’s new battery is now live, the company says. The system only uses “around one percent of critical elements” in comparison to similar lithium-ion systems.</p>
