The project will enable Positive Energy to develop and test a prototype energy storage system that reuses used electric vehicle batteries, a product that is currently not used in isolated and northern locations. The commercial potential is attractive, as it would help to resolve the issues of electricity supply in isolated communities, the penetration of renewable energies and the management of batteries after their first useful life in vehicles. The partnership is a promising one, with each party contributing complementary expertise (the customer, through its know-how in i-the reconditioning of used batteries, and ii-the assembly of batteries for stationary use on a utility scale; the research centre, through its design, optimisation of energy flows, opportunity study, performance tests on its research infrastructure and competitive analysis), enabling risks to be reduced. Ultimately, the project could lead to the development of a competitive advantage for the company and for Quebec in the growing market for infrastructure dedicated to the energy transition and reducing our carbon footprint.
