Moment Energy Secures $40 M Series B to Build Second‑Life Battery Factory for AI Data Centers

Why It Matters

The financing underscores a pivotal shift toward circular economy solutions in the energy sector, where used EV batteries become a strategic asset rather than waste. By unlocking this domestic resource, Moment Energy not only reduces reliance on imported raw materials but also offers a faster, cheaper path to grid‑scale storage—a critical need as AI workloads push data‑center power consumption beyond existing grid limits. If successful, the model could accelerate the broader adoption of second‑life batteries across other high‑intensity sectors, such as manufacturing and transportation, creating a new revenue stream for automakers and a scalable tool for utilities seeking to meet renewable‑energy integration targets while maintaining reliability.

Key Takeaways

• Moment Energy raised $40 million in a Series B led by Evok Innovations, bringing total funding above $100 million.
• The round will fund the construction of the largest North American second‑life battery factory, targeting AI data‑center storage.
• Certified to UL 1974 and UL 9540A, the company's systems can operate up to 30 years, double the lifespan of conventional storage.
• Moment claims storage costs can drop to about 3 cents per kWh, roughly three times cheaper than traditional battery solutions.
• Its pack‑swapping architecture delivers up to 164 MWh of storage per acre, enabling high‑density deployments in space‑constrained sites.

Pulse Analysis

Moment Energy’s Series B is more than a capital raise; it marks the maturation of a niche technology into a potential mainstream energy‑storage pillar. Historically, second‑life battery projects have struggled with safety certifications and economic viability, often relegated to pilot programs. By securing UL 1974 and UL 9540A approvals, Moment has cleared a regulatory hurdle that has kept many competitors at bay, positioning it as the first mover with a commercially scalable product.

The timing aligns with a perfect storm: AI‑driven workloads are inflating data‑center power demand, while new grid capacity lags behind. Traditional utility‑scale storage solutions, built on fresh lithium‑ion cells, face long lead times and exposure to geopolitical supply‑chain disruptions. Moment’s domestic, repurposed‑battery approach offers a rapid‑deployment alternative that can be scaled within months rather than years. This advantage could force utilities and large‑scale developers to reconsider their procurement strategies, potentially shifting a portion of future storage contracts toward second‑life providers.

Looking ahead, the real test will be whether Moment can sustain its cost advantage at scale. The 3‑cent/kWh figure hinges on the continued availability of high‑health EV batteries and the efficiency of its pack‑swapping process. As the EV market expands, the supply of retiree batteries will grow, but so will competition from other repurposing firms and from emerging solid‑state storage technologies. Investors will be watching the Texas factory’s ramp‑up closely; a successful launch could cement Moment’s leadership and catalyze a wave of similar projects, while any delay or cost overrun could reaffirm skepticism about second‑life economics. Either way, the $40 million infusion has placed Moment Energy at the forefront of a critical intersection between climate‑tech and AI infrastructure.
