Neothermal Energy Storage, co-founded by Dr. Louis Desgrosseilliers (MASc’12, PhD’16) and Jill Johnson, has begun testing its electric thermal storage unit in anticipation for an early adopter pilot project this fall. Dr. Desgrosseilliers developed the product, designed to help homeowners manage their energy use, during his mechanical engineering studies at Dal.


After a few years of development, Neothermal Energy Storage of Halifax is beginning two demonstration projects for its electric thermal storage unit, or ETS, which helps homeowners manage their energy consumption.

Led by Co-Founders Louis Desgrosseilliers and Jill Johnson, Neothermal has developed an electrical unit about the size of a trunk that stores heat in homes that use electrical or oil heating. It works in a similar way to a rechargeable hand warmer, with the same salt mixture inside.

The idea is that the homeowner can charge the heater at night when electrical rates are lower, then release the heat during the day. By not using electricity during the high-priced daytime periods, the device can lower heating costs by as much as half, say the co-founders.
