Narval Energy Inc.

Narval Energy is a Vancouver-based energy-tech company developing nextgeneration battery modules for extreme environments. Its sodium-based technology uses earth-abundant, non-toxic materials and operates reliably across the widest temperature range in the market – from –50 °C to 200 °C – while avoiding the safety
issues associated with conventional batteries.

At the core of their system is a novel sodium battery cell chemistry originally developed at the University of British Columbia. Starting in Canada’s remote areas, Narval’s vision is to unlock access to clean and reliable energy storage anywhere on Earth.

The Problem

Affordable and scalable energy storage is the missing piece for integrating intermittent renewable energy at a bigger scale, especially in regions with extreme climates. Conventional lithium-ion battery cells struggle in both hot and cold environments, leading to significantly higher system CAPEX and OPEX due to requirement for complex thermal management system and lower energy efficiency. This prevents their adoption in remote Canadian areas, where the cost of energy is already more than 5x higher than for the rest of Canada due to reliance on transported diesel.

These high costs place a financial burden on households and on governments that subsidize them. According to the Pembina Institute, direct federal and provincial subsidies to diesel-reliant communities are $300–400 million annually, excluding indirect costs and environmental damages.

The Solution

Narval Energy is developing a sodium-based battery system engineered to operate efficiently in extreme cold.

Narval’s technology addresses the problem at both cell chemistry and module design levels, eliminating the need for complex thermal systems and dramatically reducing system and operational costs in these harsh environments.

With NorthX’s support, Narval will build its first 5 kW field-ready prototype, a critical step toward validating performance in real-world sub-zero conditions. This milestone will unlock customer pilots, accelerate the company’s path from TRL 4 to TRL 6, and strengthen its IP position. The field prototype will enable performance benchmarking, early integration feedback from users, and progress toward commercial viability. It is a first bigger milestone towards meeting Narval’s objective of delivering 100 kW+ battery systems for remote communities.
