What e-Zinc does
e-Zinc is a Toronto-based energy storage company developing zinc-air electrochemical systems that deliver 24+ hours of discharge duration for commercial, industrial, military, and remote-microgrid applications. The proprietary technology stores energy by precipitating zinc metal onto electrodes within a water-based, non-flammable electrolyte; air injection is used on discharge to dissolve the zinc back into solution. The architecture decouples power from energy, allowing low-cost incremental scaling of capacity using abundant, recyclable commodity materials (zinc, water) rather than scarce inputs like lithium or cobalt.
Products are delivered as turn-key containerized systems, pre-assembled and pre-tested at the company's 42,000 sqft pilot manufacturing facility in Mississauga, Ontario, and shipped to customer sites for installation by channel partners including EPCs, system integrators, and project developers. Each unit ships with integrated electrical drive train, Balance of System (BOS), and a Battery Management System (BMS) that connects with building management systems. Pricing is project-based rather than listed, with custom 'Economic Value assessments' comparing the system against lithium-ion and diesel alternatives; the company claims up to an 80% cost advantage versus comparable lithium-ion systems for long-duration (8+ hour) use.
e-Zinc generates revenue through hardware sales of these storage systems, complemented by pilot project engagements with strategic customers such as the California Energy Commission (deploying at the Rapid Integration and Commercialization Unit at Miramar Marine Base in San Diego) and Toyota Tsusho Canada Inc. (at a Southern Ontario manufacturing facility). The go-to-market is direct enterprise field sales into commercial-industrial resilience and remote/microgrid segments, supported by a US regional office in Parsippany-Troy Hills, New Jersey. The company has raised approximately USD 56 million in Series A funding (Anzu Partners-led $25M in 2021/2022 plus Evok Innovations-led $31M Series A2 in 2024), USD 7M in venture debt from Silicon Valley Bank, and multiple non-dilutive grants from Breakthrough Energy, SDTC, NRCan, and the California Energy Commission.

e-Zinc competitors and assessment
Company assessmentBroad incumbents
- Tesla Energy: Operator of Megapack, Powerwall, and Autobidder platforms targeting grid-scale and behind-the-meter storage. Largest commercial energy storage incumbent whose continued cost declines and duration extensions pose a major competitive threat to e-Zinc.
- Fluence Energy: Public, leading global provider of utility-scale battery energy storage systems (mostly lithium-ion today). Broad incumbent competitor that overlaps with e-Zinc in commercial/industrial and grid-scale storage but uses lithium-ion chemistry.
Emerging players
- Highview Power: UK-based developer of liquid air energy storage (LAES) for long-duration, grid-scale applications. Competes with e-Zinc in the multi-hour to multi-day LDES market via cryogenic storage.
- Antora Energy: Developer of thermal energy storage systems for industrial decarbonization and grid applications. Adjacent LDES competitor addressing industrial heat and power with a different storage medium.
- VRB Energy: Developer of vanadium redox flow batteries for grid-scale long-duration energy storage. Competes in the same long-duration, multi-hour commercial/utility segment using flow battery architecture.
- Salient Energy: Early-stage developer of zinc-based battery technology for stationary storage. Shares e-Zinc's zinc electrochemistry foundation and LDES focus but is at a smaller, earlier commercialization stage.
Direct peers
