March 31, 2015 – Energy storage company NRStor says it has partnered with General Compression and SustainX to build large-scale, fuel-free compressed air energy storage (CAES) in Ontario.

“Our new partnership with General Compression and SustainX means that we have world-class energy-saving technology at our fingertips,” said Annette Verschuren, CEO of NRStor. “Working together with the province, we will build a more sustainable energy model that will be more cost-effective for future generations.”

CAES absorbs surplus energy during low-demand or transmission-constrained periods and returns it to the grid when needed, explains NRStor, adding that CAES is a “cost-effective, long-duration energy storage technology that […] can effectively provide reliable baseload power… something wind generation cannot do on its own”.

According to NRStor, General Compression estimates that the installed cost of its long-duration storage project will be less than 1/10th of the estimated $350/kWh for battery storage projected for the year 2022.
