Hydro-Québec and Sony have launched Esstalion Technologies, a joint research and development venture to test a 1.2-MWh grid storage prototype involving 576 lithium-ion batteries.
“Although the companies describe the unit as storing enough electricity for 48 Quebec homes, it is aimed squarely at the grid-scale market,” Greentech reports. That market “could grow to between 14 and 40 gigawatts, according to various estimates.”
The phosphate-lithium-ion modules been available since 2011, and Sony says they last more than 10 years. Hydro’s Manager of Energy Storage and Conversion, Karim Zaghib, pointed to the units’ longevity as a “crucial competitive advantage,” Stone writes.
“While the batteries are Sony’s, it appears the chemistry is Hydro-Québec’s,” he notes. “Zaghib confirmed that his company has been licencing the battery chemistry to the Japanese giant since 2003.”
