Glacies recognizes that energy storage is key to integrating renewable energy and building a cleaner, more resilient future.
​
In 2021, we identified a major opportunity — to decarbonize mine air heating, one of the largest sources of emissions in underground mining. Since then, we’ve developed our Low-Carbon Mine Air Heater (LCMAH), powered by a breakthrough process called Spray Freeze Heating (SFH). This technology uses water and ice as thermal storage media, unlocking new ways to provide efficient heating and cooling.

Our vision: leverage water and ice for heating, cooling and energy storage.
About us
Product
Glacies’ Low-Carbon Mine Air Heater offers a sustainable alternative to conventional mine heating system. Conventional mine air heating systems account for over 20% of total CO2 emissions of an underground mine operation.
Each unit is designed to handle up to 150,000 SCFM (70.8 m³/s), enabling it to replace or supplement existing mine heating infrastructure while significantly reducing CO2 emissions. Multiple LCMAH units can operate in parallel to serve larger ventilation systems, with each capable of a 20–30°C temperature rise, depending on site conditions.
With its compact tower configuration (7×5 m footprint, 11 m high), the LCMAH integrates easily into existing mine layouts, offering a retrofit-ready path to decarbonization.

Projects
Collaborating with B2Gold:
Advancing Low-Carbon Mine Air Heaters
Glacies and B2Gold are collaborating on a pilot demonstration of a Low-Carbon Mine Air Heater technology for arctic conditions — a world first designed to reduce CO2 emissions from underground mining operations.
B2Gold is a responsible international senior gold producer headquartered in Vancouver, Canada. The Company has operating mines in Mali, Namibia, the Philippines as well as the new open pit and underground complex at the Goose Mine in Nunavut, Canada.
During the winter of 2025-2026, Glacies will operate a 15 000 SCFM (7.08m3/s) pilot unit in Sherbrooke, Québec, to demonstrate the performance of its low-carbon mine air heater adapted for arctic conditions. The pilot will generate key performance data on thermal output, cold climate stability, energy efficiency and carbon emission reduction. This pilot is a stepping-stone toward deploying the system in arctic conditions at Goose Mine.
This partnership reflects B2Gold’s commitment to responsible mining in arctic environments and Glacies’ mission to accelerate decarbonization across the mining industry.
Glacies will share updates throughout newsletters, LinkedIn posts and during an exclusive Demo Day in March 2026.

Demo Day
Glacies and B2Gold will host a Demo Day in early March 2026. The event will take place in two phases.
Phase 1 – PDAC 2026 (March 1–4):
During the Prospectors & Developers Association of Canada (PDAC) Convention, Glacies will share results and hands-on insights from the pilot unit at booth #6201N in the North Pavilion. Visitors will also have the opportunity to take part in a virtual tour of the pilot system.
Phase 2 – Sherbrooke Pilot Visit (March 5–6):
Immediately following PDAC, Glacies will host in-person visits to the pilot facility in Sherbrooke, Québec. Each half-day session will include a guided tour of the pilot site and exclusive meetings with representatives from Glacies and B2Gold.
Participation in the Sherbrooke visit is by invitation only. Interested parties are encouraged to contact Glacies directly (by email: info@glaciestech.com). The team will assist with accommodation and provide recommendations for activities in the beautiful city of Sherbrooke.
