For decades, Canadian cities and towns have combated ice and snow with salt and plows. This approach, however, comes at a steep cost. Traditional techniques damage roads, harm the environment and are not always effective at protecting road users from winter’s hazards. An innovative technology known as Borehole Thermal Energy Storage (BTES) could be an effective solution to Canada’s winter woes.
The technology behind BTES systems is elegantly simple.
Initially designed for building heating and cooling, a BTES system captures solar heat during the summer months and stores it underground. Then, when winter arrives, the stored heat is transferred through pipes beneath the road surface, warming the pavement and preventing ice formation — in essence, a solar powered underfloor heating system.
