It is indeed an interesting option. We carried out a pilot project designed to test the power exchange between residences and electric vehicle batteries. It was a first in both Québec and Canada. We are following the work very closely.
To learn more about this topic (video in French only):
IREQ is also conducting research with a view to marketing a large-capacity energy storage system, resulting from our work on battery materials.
Just recently, IREQ announced several commercial projects, such as the test of the first prototype of a large-capacity energy storage system, the creation of a laboratory for lithium-ion batteries (article in French only) and the development of new materials that pave the way for very powerful, next-generation batteries.
