Luna certified as stationary storage
Moment Energy
This certification stack turns a scary custom battery project into a standard piece of electrical equipment. A facilities manager can buy Luna the way they would buy any other commercial storage system, an insurer can underwrite a tested product instead of guessing at used EV pack behavior, and a permitting authority can review a listed stationary ESS with known fire test data instead of treating the site like an experiment.

Each UL mark answers a different approval question. UL 1973 covers the battery for stationary use, UL 9540 covers the full energy storage system with controls and power electronics, UL 9540A measures how a thermal runaway event spreads. Together they let the enclosure be evaluated as a purpose built ESS, not as loose automotive packs repackaged for a building.

That matters because the practical buyer is usually not the sustainability team, it is the person signing off on building risk. For that group, the hard part is not whether second life batteries are cheaper, it is whether the system fits existing code review, fire planning, and insurance workflows with standard documentation and test results.

Moment still carries a higher proof burden than first life BESS vendors because second life systems start with batteries that already lived inside vehicles. The companys edge is that it screens packs in a UL 1974 certified process, replaces the original vehicle controls with its own standardized software layer, and then sells the result as one certified product.
The next step is turning certification into bankability at scale. As more Luna systems operate in airports, logistics sites, EV charging hubs, and data centers, the winning asset will be a growing file of loss history, performance data, and repeat approvals that makes repurposed batteries feel routine to insurers, lenders, and local authorities.
