Momento Energy

Momento Energy is a Moss Landing, California-based startup focused on giving retired electric vehicle (EV) batteries a second life as stationary energy storage systems. Rather than sending end-of-life EV battery packs to recycling or landfill, the company repurposes them into grid-connected or behind-the-meter energy storage systems - significantly reducing the cost of energy storage while diverting battery waste from the waste stream. Moss Landing is a strategically important location, situated at the heart of California's grid infrastructure and near some of the world's largest battery energy storage installations.

The second-life battery market addresses a critical challenge in the energy transition: EV batteries typically retain 70-80% of their original capacity when they are retired from vehicles, making them well-suited for less-demanding stationary storage applications such as peak shaving, demand charge reduction, and renewable energy integration. By extending battery life before eventual recycling, companies like Momento Energy help reduce demand for virgin battery materials, lower the carbon footprint of energy storage, and bring down the levelized cost of storage for commercial and utility customers.

Momento Energy sits at the intersection of two major trends in the US energy supply chain: the rapid growth of EV adoption (which will generate millions of retired battery packs over the coming decades) and the urgent need for affordable, large-scale energy storage to support grid decarbonization. As a lifecycle and recycling-layer player, the company plays an important role in creating a more circular battery economy in the United States, reducing dependence on imported critical minerals, and supporting domestic energy resilience.
