When contacting IR over the past year they have continually focused on the opportunities in grid storage. After doing some research on the subject I can finally see why. This area is exploding and I believe the profits are much higher, EV applications are very competitive and there is extreme pressure to keep costs (and therefore profits) down as much as possible. I think you will see electrovaya concentrate most of it's focus on grid storage. They have several MWh scale demo projects in the works, two to be completed this year.
