Moment Energy has closed a $40 million Series B funding round to scale what it describes as North America's largest second-life battery storage platform, bringing total capital raised to over $100 million. The round was led by Evok Innovations, with participation from Liberty Mutual Investments, W23 Global Fund and Acario, the corporate venture capital arm of Tokyo Gas. Existing investors including Amazon's Climate Pledge Fund, Voyager Ventures and In-Q-Tel also remain part of the company's capital base.

 

Why Second-Life Batteries Matter Now

 

The funding lands at a moment when AI workloads, data centre buildouts and broader electrification are placing the North American grid under unprecedented strain. Legacy battery manufacturers continue to face long lead times, high capital expenditure requirements and geopolitical supply chain exposure, particularly for inputs originating from constrained jurisdictions. Moment Energy is positioning itself as a counterweight by activating millions of electric vehicle batteries already in circulation on the continent.

Edward Chiang, Co-Founder and Chief Executive Officer of Moment Energy, said AI is exposing structural weaknesses in the grid that cannot be solved by waiting for the next round of utility infrastructure upgrades. He framed the company's strategy as the start of an era of independent energy, free from grid bottlenecks, supply chains the United States does not control and decades of additional raw material extraction. The framing aligns with broader policy interest in domestic energy resilience and supply chain sovereignty.

Certifications and Commercial Readiness

 

The company has cleared a series of critical safety milestones that have historically prevented second-life battery solutions from reaching enterprise deployment at scale. Moment Energy holds UL 1974 and UL 9540A certifications, which it says make it the only provider capable of deploying second-life battery storage systems in the built environment without special dispensations or regulatory loopholes. These certifications are essential for installation in data centres, hospitals, factories and microgrids where insurability and regulatory compliance are non-negotiable.

The company's certified status materially shortens project development timelines for industrial and commercial customers, since insurance, permitting and code approval pathways are already established. By moving second-life storage from pilot use cases to fully certified commercial deployment, Moment Energy has created a defensible competitive position. Marty Reed, Partner at Evok Innovations, said the company has demonstrated that safety and scalability are not mutually exclusive in the EV battery repurposing industry.

 

Economics and System Performance

 

Moment Energy is also redefining the underlying economics of stationary storage through its proprietary pack-swapping architecture. The design extends system lifespans to 30 years, roughly double the 15-year lifecycle typical of conventional battery storage systems. Combined with domestic tax incentives available under United States policy frameworks, the architecture supports up to three times lower net costs and reduces cycling costs to 3 cents per kilowatt hour for industrial customers.

Power density is another core differentiator for the company's offering, particularly in space-constrained industrial environments. Moment Energy has engineered what it describes as the world's most dense second-life battery system, supporting up to 164 megawatt hours of storage per acre. The compact footprint maximises return on investment per square foot in high-value sites such as urban data centres, manufacturing campuses and logistics hubs. The system is fully Foreign Entity of Concern compliant, which makes it eligible for the full range of domestic incentives.

Manufacturing Footprint and Strategic Partnerships

 

Proceeds from the Series B will support the scale-up of Moment Energy's Texas Gigafactory alongside its existing facilities in British Columbia. The dual-country manufacturing footprint is designed to anchor a domestic supply chain for second-life battery storage that can serve customers across the United States and Canada. Foreign Entity of Concern compliance is increasingly central to procurement decisions by hyperscale operators and industrial buyers seeking to qualify for federal tax credits and reduce geopolitical exposure.

The company partners with major automakers, including Mercedes-Benz Energy, to put retired electric vehicle batteries back to work before they are recycled. This upstream sourcing arrangement provides a structurally advantaged feedstock pipeline that does not rely on new cell manufacturing capacity. By converting an end-of-life automotive asset into a productive grid resource, Moment Energy extends the economic value of batteries that have already been manufactured and deployed.

 

Outlook for Storage and Grid Resilience

 

The investment landscape for energy storage is shifting toward solutions that combine speed of deployment with supply chain resilience, both of which are central to Moment Energy's value proposition. As hyperscalers and industrial customers face escalating power constraints, the ability to deliver certified, insurable storage systems quickly is becoming a competitive advantage in its own right. The Series B funding gives the company the runway to convert proven technology and certifications into deployment volume.

Whether second-life storage emerges as a structural pillar of the North American grid will depend on the pace of capacity build-out, the availability of retired battery feedstock and continued policy support for domestic clean energy supply chains. Moment Energy's combination of certifications, manufacturing scale and pack-swapping architecture positions it as a leading contender to define that segment. Continued execution on customer wins and gigafactory ramp will be the next test.
