Advances in battery materials

IREQ has extensive expertise in lithium-ion battery materials for ground transportation, both personal and public, and grid-scale energy storage.

Hydro-Québec is developing next-generation, large-capacity energy storage solutions that facilitate the management of constantly rising demand peaks. These safe, reliable and highly efficient solutions can be used to work intermittent renewables like wind, hydrokinetic and photovoltaic power into the grid, which will help achieve GHG emission reduction targets.

Overview of IREQ’s energy storage innovations

LFP: Avant-garde technology

Combining its expertise in electrode material chemistry and know-how in power transmission and distribution system operation, Hydro-Québec designed an innovative olivine-type lithium iron phosphate (LFP) technology for large-scale energy storage.

Pioneering grid-scale energy storage

The Hydro-Québec energy storage system

Hydro-Québec’s grid-scale energy storage system is one of the safest and most efficient currently under development.

1.2-MWh capacity

20-year service life


15,000 charging cycles

No risk of thermal runaway or combustion, since iron is nonflammable and thermally stable

99% recyclable

toxic metals (such as nickel or cobalt)
