What Glacies Technologies does

Glacies Technologies Inc. is a Sherbrooke, Québec-based private company, founded in 2021 with a team of 1-10 employees, that has developed the Low-Carbon Mine Air Heater (LCMAH) — a thermal storage system targeting one of the largest emissions sources in underground mining: conventional mine air heating, which accounts for over 20% of total CO2 emissions of an underground mine operation. The company's core innovation is a proprietary process called Spray Freeze Heating (SFH), which uses water and ice as phase-change thermal storage media to deliver heating (and cooling) to mine ventilation air. Each LCMAH unit handles up to 150,000 SCFM (70.8 m³/s) with a 20-30°C temperature rise, fits a compact 7×5 m, 11 m-tall tower footprint, and scales to 600,000 SCFM via parallel four-tower configurations, enabling retrofit into existing mine ventilation layouts. The technology is described as the first known system specifically designed for low-emissions mine air heating in arctic conditions, with no direct disclosed competitor alternative.

Glacies targets underground mine operators in Arctic and northern jurisdictions such as Nunavut and Northern Canada, where heating demand is high, fossil-fuel dependence is acute, and decarbonization is a regulatory and reputational priority. Its commercial model is enterprise direct sales of custom-engineered LCMAH hardware (or leasing), with site-specific quoting and long technical-evaluation sales cycles. The company is currently pre-commercial and is conducting a world-first arctic pilot in partnership with B2Gold at the Goose Mine in Nunavut; during winter 2025-2026, Glacies operated a 15,000 SCFM (7.08 m³/s) arctic-adapted pilot unit in Sherbrooke, Québec, to validate cold-climate performance ahead of arctic deployment. Distribution is conducted via direct enterprise field sales, supplemented by industry-event presence (PDAC 2026, booth #6201N) and a co-branded Demo Day with B2Gold in March 2026.

The company has secured approximately C$5 million in non-dilutive grant funding from the Government of Canada's Critical Minerals Infrastructure Fund (May 2026), with additional grant funding from Natural Resources Canada (approximately C$3.6 million) and the Mining Innovation Commercialization Accelerator (C$183,000, June 2024). This funding anchors Glacies within Canada's national Critical Minerals Strategy and positions the LCMAH as a strategic decarbonization technology for Arctic mining. The company has no disclosed revenue, no institutional venture investors in the public record, and its broader stated vision is to leverage water and ice for heating, cooling, and energy storage applications beyond mine air heating.

Core offering

Glacies Technologies designs, manufactures, and sells the Low-Carbon Mine Air Heater (LCMAH), a thermal storage system powered by its proprietary Spray Freeze Heating (SFH) process. The LCMAH uses water and ice as thermal storage media to provide efficient heating and cooling for underground mine ventilation, targeting decarbonization of mine air heating which accounts for over 20% of total CO2 emissions in underground mining operations. Each unit handles up to 150,000 SCFM (70.8 m³/s) with a 20–30°C temperature rise, and multiple units scale in parallel for larger systems.

Product overview

Glacies Technologies offers a single core product, the Low-Carbon Mine Air Heater (LCMAH), powered by its proprietary Spray Freeze Heating (SFH) technology. The LCMAH uses water and ice as thermal storage media to provide efficient heating and cooling for underground mines, serving as a sustainable alternative to conventional mine heating systems that account for over 20% of total CO2 emissions in underground mining operations. Multiple LCMAH units can operate in parallel to serve larger ventilation systems.
