Noon Energy successfully demos its 100-hour carbon-oxygen battery

Noon Energy has been successfully operating its 100-plus-hour battery for multiple months, the company announced today. And the demonstration of the long-duration energy storage system ended up with far more capacity than the company had originally pitched; it ultimately operated for thousands of hours over the course of the test, with over 200 hours of storage capacity.  

The system is a reversible solid oxide fuel cell battery that relies on carbon and oxygen, with tanks and power blocks that can fit inside standard shipping containers. Chris Graves, co-founder and CEO of Noon Energy, told Latitude Media that he believes it’s the first fully containerized system for multi-day to seasonal energy storage to operate for such a long period of time.
