It is indeed an interesting idea.
In fact, Hydro-Québec’s research institute (IREQ) is very active on the R&D front. Just recently, IREQ announced several commercial projects, such as the test of the first prototype of a large-capacity energy storage system.
The prototype has a capacity of 1.2 MW and can store 1.2 MWh, equivalent to the daily consumption of 23 Québec homes. The prototype is made up of a container measuring 16.2 meters (53 feet) that consists of 576 battery modules, an inverter to convert the current, a transformer to adjust the storage system voltage to that of the grid as well as control and protection equipment. The battery modules are manufactured by Sony and use Hydro-Québec’s lithium iron phosphate technology, patented by Hydro-Québec.
We are very proud of IREQ’s innovations and love discussing them!
