Funding Targets A Growing Grid Bottleneck

Austin, Texas-based Moment Energy has raised more than $40 million to expand second-life battery manufacturing at a time when AI-driven power demand is testing North America’s electricity infrastructure.

The oversubscribed Series B round was led by Evok Innovations. Liberty Mutual Investments, W23 Global Fund, and Acario, the corporate venture capital arm of Tokyo Gas, also participated. Existing major investors include Amazon’s Climate Pledge Fund, Voyager Ventures, and In-Q-Tel.

The round brings Moment Energy’s total funding to more than $100 million. The company said the capital will support a larger North American manufacturing footprint, specialist hiring, and expanded production capacity across the US and Canada.

For data centers, utilities, and industrial energy buyers, the timing is significant. AI workloads are increasing electricity demand, while grid connections, storage supply chains, and project timelines remain under pressure. Moment Energy is positioning second-life EV batteries as a domestic resource that can be deployed faster than conventional storage systems.

“As energy demand continues to increase, Moment Energy is focused on one mission: improving grid resilience and reducing energy costs,” said Edward Chiang, Co-Founder and CEO of Moment Energy. “We are building a new generation of energy infrastructure that can be deployed rapidly, manufactured domestically and powered by existing battery resources.”

Second-Life Batteries Move Toward Commercial Scale

Moment Energy repurposes used electric vehicle batteries into commercial energy storage systems. The model addresses two problems at once. It gives EV batteries a second productive life, while adding storage capacity for power users that need more flexibility.

The company said it has reached safety benchmarks that are critical for commercial deployment. These include UL 1974 and UL 9540A certifications. According to Moment Energy, this makes it the only provider able to deploy second-life battery storage systems in the built environment without special dispensations.

That distinction matters for C-suite buyers. Data centers, manufacturers, property owners, and utilities need storage systems that can meet safety, insurance, and permitting requirements. Without that confidence, second-life battery projects can struggle to move beyond pilots.

Moment Energy argues that its approach can now serve mainstream commercial infrastructure. The company says its systems are FEOC compliant, insurable, scalable, and built for high-value locations where space is limited.

Cost And Density Drive The Business Case

Energy storage economics are becoming a boardroom issue as companies manage rising power demand, grid delays, and decarbonization targets. Moment Energy says its proprietary pack-swapping architecture can extend system lifespan to 30 years, compared with a typical 15-year lifecycle for conventional systems.

The company also says its systems can deliver up to three times lower net costs when paired with domestic tax incentives. For industrial users, cycling costs can fall to as low as 3 cents per kWh.

Those economics could prove important for buyers facing volatile electricity prices and constrained grid capacity. Storage can help companies shift demand, improve resilience, and reduce exposure to peak pricing. For AI data centers, it can also support faster energy deployment in markets where grid interconnection delays are now a growth constraint.

Moment Energy says its compact systems can deliver up to 164 MWh of storage per acre. That density is aimed at sites where land value, square footage, and power availability shape project returns.

“Moment Energy is the only player in the EV battery repurposing industry that has proven safety and scalability are not mutually exclusive,” said Marty Reed, Partner at Evok Innovations. “With a deep understanding of battery health and chemistry, Moment Energy is uniquely positioned to build and deploy high-performance, second-life systems at enormous scale. This is a real-world use case for Physical AI: turning complex data into the reliable energy storage needed to power our future.”

What Executives Should Watch

Moment Energy’s funding reflects a broader shift in energy infrastructure finance. Investors are backing technologies that can reduce reliance on global battery supply chains, support domestic manufacturing, and improve grid resilience.

For policymakers, second-life batteries also sit at the intersection of industrial strategy and circular economy goals. Repurposing EV batteries can lower waste, reduce pressure on new mineral supply, and keep more value inside regional energy markets.

For companies, the practical takeaway is direct. Power availability is becoming a competitive constraint. Firms that depend on electrification, AI, or industrial load growth may need storage strategies that go beyond traditional procurement.

Moment Energy’s expansion will test whether second-life batteries can scale from a promising circular economy solution into core grid infrastructure. If the company can deliver on safety, cost, and manufacturing claims, its model could help North America unlock storage capacity already sitting inside EV batteries on the road.
