We are currently rebuilding it. We are active and publish news on LinkedIn.

Since you are here, here’s what we do and what we are:

Glacies is currently developing a net zero GHG emissions heating system for underground mines ventilation. We call this device the Glacies reactor. Our reactor uses the phase change properties of water to generate heat below freezing temperatures. It may sound counterintuitive, but it works. To make ice with water, you need to extract a lot of heat (cool it down). We extract that energy and put it into the air flowing down the mine ventilation shaft. We can heat the air to almost 0 Celsius with our technology. We shared some results on LinkedIn regarding the demonstration of our system with a rated power of 280kW. A full-size Glacies reactor has a rated power of 2.8MW (150 000CFM, -32C to -2C). We will make one next winter (2023-2024)

Right now, the industry standard is to burn gas to heat the ventilation air. Those gas burners are generating more than 20% of all the mine GHG. Our technology is a low-hanging fruit in this industry to reduce the environmental impact of mines. We need to extract primary minerals (in part to enable the electrical vehicle revolution), let’s do it by having a small environmental impact at the source.

Glacies global vision is to enable seasonal thermal storage: meaning using the passage of seasons (winter-summer) to store heat using the phase change properties of water. The end goal is to reduce our impact on the environment for heating and cooling applications.

The mining industry is a good fit for our heating reactor technology. Mining companies are looking for decarbonization solutions. Many mines are committed to be net-zero by 2050 with ambitious goals for 2030. It is also well known that they have pressure from populations, governments, and the financial market to have the smallest impact on the environment.

It is in this context that Glacies is offering a technology that surpasses all other GHG reduction initiatives for mines (diesel in trucks, concrete, electricity origin). We can rapidly reduce by 70% the GHG emissions related to underground ventilation heating. Our solution is all on the mine surface and automated. The only input is water, and the only output is ice. The reactor is very efficient, the coefficient of performance is around 20 (meaning we use 1kW of electricity to generate 20kW of heat). We reduce the dependence on gas and the volatile prices that comes with it. Over 10 years, the cost of decarbonization is negative, meaning our technology has a payback period lower than 10 years. In some cases, the payback is one year, but keep in mind 5-7 years and that should look like it. We do need to do a study for each site and we need water.

Also, we will then use the ice produced during winter and cool your mine during summer once you need it. That is our vision: seasonal thermal storage.
