HiTHIUM enters Canada with first 8-hour BESS and sodium-ion solutions adapted to extreme cold

TORONTO, Oct. 21, 2026 /PRNewswire/ -- HiTHIUM, an integrated full-scenario energy storage solutions provider, has announced its entry into the Canadian market. Ranked in the top two globally for energy storage component, the manufacturer has surpassed 200 GWh in cumulative delivered capacity, focusing exclusively on stationary energy storage technologies.

Canada's energy storage expansion requires reliable large-scale suppliers and local presence

Mizhi Zhang, HiTHIUM President of Global Business, commented: "We are committed to delivering Canadian customers advanced, robust solutions, from 8-hour long duration energy storage to extreme-weather-ready sodium-ion BESS. But this also means being present for customers wherever they are, able to serve them quickly and locally. While Toronto serves as the main hub for our Canadian operations, we have subsidiary offices in British Columbia and Alberta, as well as operating sites in Quebec, Yellowknife, and Fort Smith." 

HiTHIUM has introduced 4-hour and 8-hour BESS solutions to serve the market's rapid buildout of utility-scale energy storage. With installed Canadian storage expected to double between 2025 and 2027, and the country's total wind, solar, and energy storage capacity on track to reach 50 GW by 2035, HiTHIUM is positioned to fill the growing demand for BESS on a large scale. The company has also revealed a new 4 MWh sodium-ion storage solution, which is designed for an extra-long service life, supports storage durations from 2 to 8 hours, and is perfect for extremely cold climates, like Northern Canada.

"Canada's ambitious clean energy targets, as well as its high safety and regulatory standards, require partners who can deliver advanced technology that's also tested and compliance-ready. At the same time, project developers have to consider the tough climate. As a vertically integrated, global solutions provider, HiTHIUM is structured to meet exactly this nexus of challenges. Our strategy of advancing both lithium-ion and sodium-ion storage is designed to offer customers in markets like Canada the benefits of flexibility, since we see these technologies as highly complementary," continued Zhang.

"Our partners, whether major energy developers, public utilities, or industrial enterprises, rely on our readiness for local certification and our long-term bankability to support them, from permitting through project commissioning," added Jordan Hebbert, HiTHIUM Senior Manager of Canada. "Likewise, they depend on the proven durability of HiTHIUM technology—including performance even in extreme weather conditions. In fact, long-term operational data from North American and European projects has recently demonstrated systems outperforming even our guarantees. And we offer customers a wider range of durations and choice of chemistries because we understand that they're coming to us with a very diverse range of energy storage needs."

4-hour or 8-hour BESS: Matching duration to project specifications

The manufacturer's 4-hour BESS solution consists of its "∞Power" 6.25 MWh container, built on HiTHIUM's own 1175 Ah cell. Most Canadian projects are currently designed around the 4-hour unit. This enables them to shift wind, solar, and baseload output to later peak times, strengthen grid reliability, and drive the consumption of more renewables, particularly as electrification increases demand. The ∞Power system design fits more capacity into the typical 20-foot container but also reduces a project's overall footprint, because the containers can be placed back-to-back and side-to-side.

In a groundbreaking step for long duration energy storage, HiTHIUM also developed the first ever native 8-hour solution based on lithium-ion technology. Its 6.9 MWh 8-hour BESS, built with HiTHIUM's own 1300 Ah cells, fewer components overall, and a 25-year lifespan, is designed to address issues like curtailments and to fill key gaps for zero-downtime industrial segments like AI data centers. For wind project developers and data center operators alike, 8-hour BESS offers risk reduction and greater revenue reliability.  

Extreme fire test validates safety architecture

HiTHIUM additionally worked with UL Solutions at the start of 2026 on an independently conducted, extreme fire test of its 6.25 MWh block's intrinsic safety systems. A container was subjected to 24 hours of extreme combustion conditions, with its doors opened for maximum thermal spread, while neighboring containers were placed just 15 cm away. Only the containers' passive safety systems were enabled. The results validated HiTHIUM's multi-layer safety architecture, with the tested container structurally intact after the test, no thermal propagation across the containers, and the temperatures of cells in adjacent containers remaining below safety thresholds.
