Moment Energy closed a $40M Series B in May 2026, led by Evok Innovations, with participation from Liberty Mutual Investments, W23 Global Fund, and Acario.

Before the Series B, Moment Energy closed a Series A in January 2025, raising $15M. Earlier rounds include a seed round of $3.5M. The company also received non-dilutive capital, including a $20.3M award from the U.S. Department of Energy to establish its Texas repurposing facility, as well as funding from PacifiCan to expand Canadian production capacity.

Investors across rounds include Amazon Climate Pledge Fund, Voyager Ventures, In-Q-Tel, Version One Ventures, Fika Ventures, Garage Capital, and MCJ Collective. Total capital raised across equity and non-dilutive sources exceeds $100M as of May 2026.

Moment Energy builds commercial battery energy storage systems from repurposed large-format EV battery packs. Its core product, Luna BESS, is a containerized, three-phase storage system that starts at 400 kWh and scales to 1 MWh in standard configurations, with larger deployments reaching 10 MWh.

Luna sits between a building and the grid as a controllable electricity buffer. It charges when power is cheap or when on-site solar is generating surplus energy, then discharges to reduce peak demand, ride through an outage, or support a bank of EV fast chargers without waiting years for a transformer upgrade. The system connects to a facility's existing electrical infrastructure via 480 VAC three-phase input/output, with no need to rebuild the building around it.

The product differs from a conventional BESS in its battery supply chain and controls stack. Rather than using new lithium-ion cells, Moment Energy sources retired EV battery packs from automakers and fleet operators, screens them at a UL 1974-certified facility, grades them by remaining state of health, and rebuilds them into stationary systems using its own battery management software. The company removes the original automaker BMS and replaces it with its own controls layer, allowing it to manage packs from different chemistries, LFP, NMC, and NCA, and different vehicle platforms within a single standardized product.

The certification stack is the product's key commercial attribute. Luna is the first repurposed battery system globally to achieve UL 1973, UL 9540, and UL 9540A, while Moment Energy's repurposing facility holds UL 1974 certification. For facilities managers, insurers, and permitting authorities, that means Luna is certified as a stationary-storage product rather than a retrofitted EV battery in a box.

Luna uses a modular, pack-swappable architecture, so battery subcomponents can be refreshed over time while the enclosure, power electronics, and controls layer remain in place. That extends the system's useful life beyond a conventional sealed BESS. After commissioning, Moment Energy provides 24/7 remote monitoring and ongoing maintenance, and is developing a proprietary AI management system for battery health and safety optimization.

Moment Energy is a vertically integrated second-life battery infrastructure company. It sources retired EV packs from automakers and fleet operators, certifies and rebuilds them into standardized BESS products, and sells or deploys those systems into commercial and industrial end markets. Revenue comes primarily from system sales and project integration, with monitoring and maintenance services layered on top.

The commercial model has two sides. On the supply side, Moment Energy works with 20-plus battery manufacturers and OEM partners, including Mercedes-Benz Energy and Nissan North America, offering them a compliant, logistics-coordinated path to monetize retired packs rather than sending them directly to recycling. On the demand side, it sells to C&I facilities, data centers, hospitals, airports, and logistics operators seeking lower-cost resilient power without waiting for grid infrastructure upgrades.

Its cost advantage versus conventional BESS vendors comes from using retired EV packs, which are cheaper than new cells, instead of fresh battery commodity inputs. Moment Energy says Luna is roughly 30% more affordable than comparable new systems, with cycling costs as low as 3 cents per kWh for industrial users when combined with available tax incentives. The company also helps customers stack BC Hydro incentives, federal clean-technology tax credits, and CapEx-to-OpEx financing structures, reducing upfront budget friction and shifting the sales conversation toward operational ROI.

Manufacturing scale is the main lever in the cost structure. The Vancouver hub is at full production, and the planned Texas gigafactory targets 1 GWh of annual repurposing capacity, which would improve fixed-cost absorption across battery intake, testing, grading, power electronics integration, controls software, and field service. The model also benefits from a circular data loop: more EVs aging out increase retired pack supply, more deployed systems generate more field-performance data, and better data improves screening accuracy and safety confidence with both OEM partners and enterprise buyers.

Moment Energy competes across three overlapping fronts: second-life battery specialists, vertically integrated players that combine new and used batteries, and first-life BESS incumbents that set the price umbrella for the category.

Redwood Materials is the most consequential recent entrant in the category. Originally a recycler, Redwood now markets energy storage built from both new and repurposed batteries, claims to receive over 20 GWh of batteries annually, and says its energy business offers the lowest-cost storage on the market. Its ability to arbitrage between reuse and recycling, choosing the higher-value pathway pack by pack, gives it a feedstock advantage that pure repurposers cannot easily match.

Redwood has already deployed repurposed packs in a 12 MW / 63 MWh microgrid for Crusoe and is targeting AI data centers and other power-constrained loads where deployment speed matters more than circularity purity. That makes Redwood a second-life competitor and a vertically integrated platform that could compress margins across the category. Base Power is another model to watch: vertically integrated battery ownership paired with electricity contracts, which shows storage companies can capture recurring energy-market value rather than relying only on hardware margin.

Element Energy is a direct rival after energizing a 53 MWh second-life project and announcing a partnership with LG Energy Solution Vertech to offer turnkey second-life systems. The LG pairing matters because it reduces the execution gap that historically protected specialists: procurement teams can buy a more conventional turnkey package without underwriting the full second-life workflow themselves.

B2U Storage Solutions takes a different approach, deploying whole EV packs into grid-scale systems without the deeper teardown and rebuild that Moment Energy performs. That minimizes repurposing overhead and can preserve a lower cost structure on some project types, though it gives up some of the standardized product positioning that Moment Energy's UL certifications provide. 4R Energy, founded by Nissan and Sumitomo, represents the OEM-linked model: tighter access to battery provenance and reverse logistics addresses one of the core second-life problems, knowing exactly what is being purchased.

Tesla, Fluence, and Sungrow compete for the same end-customer budget even though they do not compete for the same feedstock. BloombergNEF reported average lithium-ion pack prices fell to $108/kWh in 2025, with stationary storage the cheapest segment, driven by overcapacity and the shift to LFP chemistry.

That price compression narrows the discount window second-life vendors need to win deals. In practice, Moment Energy is competing in each RFP against the safer procurement choice: a certified, warrantied, familiar first-life system from a vendor with broad installer relationships and established financing. Moment Energy's counterweight is its certification-led C&I product approach and its track record of insured, permitted deployments in commercial environments.

Moment Energy's TAM expansion runs in three directions: deeper into the value chain on the supply side, broader across customer segments on the demand side, and wider geographically as North American manufacturing capacity comes online.

The clearest product expansion is from a hardware platform to software-led energy services. Moment Energy is developing a proprietary AI management system for battery health and safety optimization, and its April 2026 Pulsenics partnership focuses on faster, more reliable battery qualification using advanced testing technology. Those capabilities, battery diagnostics, state-of-health grading, and lifecycle modeling, could move from internal process tools into sellable services for OEMs, insurers, fleet operators, and recyclers that need battery provenance data.

A second product vector is the supply-side service layer. Moment Energy already offers automakers and battery owners logistics coordination, certification, liability management, and end-of-life handling, in addition to BESS sales. Expanding that into a broader battery circularity service for leasing companies, dismantlers, and fleet operators would enlarge TAM beyond energy storage capex into battery disposition, compliance, and residual-value management.

Data centers appear to be the highest-growth near-term segment. BloombergNEF projects U.S. data-center power demand reaching 106 GW by 2035, and Moment Energy is framing Luna as a way to add capacity for power-hungry loads without waiting years for transformer or grid upgrades. That shifts the sales pitch from demand-charge reduction to power availability, a higher-value budget line for many customers.

EV charging infrastructure is another logical wedge because Moment Energy can participate on both sides of the market: sourcing batteries from automakers and fleets, then selling storage into charger deployments that need power buffering. The Vancouver International Airport deployment fits that pattern, a fleet electrification customer that needed flexible charger capacity without immediate grid upgrades. As EV adoption accelerates, the number of facilities facing that constraint increases.

Moment Energy's shift from a Canada-only production base to a North American manufacturing footprint is its most important near-term TAM lever. The Texas gigafactory, backed by a $20.3M DOE award, is planned as the first UL 1974-certified EV battery repurposing facility in the U.S., with roughly 1 GWh of annual capacity. That places Moment Energy closer to fast-growing storage and data-center markets and shortens logistics for both inbound retired packs and outbound BESS shipments.

The longer-term geographic opportunity is to become a second-life partner for North American automakers and fleets before the wave of first-generation EVs reaches end-of-life at scale. IEA data shows EV adoption continuing to rise globally, which increases the installed base of aging packs that can become feedstock for second-life systems. Moment Energy's early OEM relationships and certification lead could help it secure regional battery-supply corridors before the market becomes more crowded with better-capitalized entrants.

New battery deflation: As LFP manufacturing overcapacity continues to push new lithium-ion pack prices lower, BloombergNEF reported $108/kWh in 2025, the cost gap that makes second-life systems economically attractive narrows, forcing Moment Energy to compete on deployment speed, domestic sourcing, and certification rather than straightforward capex savings.

Feedstock disintermediation: Moment Energy's supply chain depends on a steady stream of healthy retired EV packs with good provenance, but OEMs, recyclers like Redwood Materials, and other second-life players compete for the same batteries, and automakers that prioritize direct recycling for critical-minerals recovery or reserve higher-quality packs for internal programs could structurally constrain Moment Energy's input economics.

Bankability burden: Even with the industry's strongest UL certification stack, second-life storage faces extra scrutiny from insurers, lenders, and permitting authorities around unknown usage history and thermal behavior, which means Moment Energy must continuously invest in safety proof points and field-performance data to remain financeable in mainstream commercial deployments, a cost burden that first-life BESS competitors do not carry.
