Hydrostor & NRStor Together For World’s First Commercial CAES Plant

Hydrostor, leading developer of Advanced Compressed Air Energy Storage, partners with Canadian energy storage developer, NRStor Incorporated. They announced today the completion of the Goderich A-CAES Plant, in Goderich, Ontario, Canada. The plant represents a leap in enduring energy storage. And also the first successful commercial fuel-free CAES technology.

The completion passed with a ribbon-cutting ceremony at the plant.

The Goderich A-CAES Facility commercially contracted with Ontario’s Independent Electricity System Operator (IESO) for maximising capacity, auxillary services and complete integration in the merchant energy market. In this way, it is supporting reliability of the grid. Completely fuel-free, the plant produces no carbon emissions, and supports enabling a cleaner, more economical, and more resilient electricity grid.

Hydrostor’s Skill in A-CAES

With 1.75 megawatts (MW) of top power output; a 2.2 MW charge rating; and 10+ megawatt-hours (MWh) of storage capacity, this success id the first in its kind, in a commercial application of A-CAES technology, adapting to all connectivity, function time, performance and transmission standards, determined by the IESO. The facility proves the skill of Hydrostor’s A-CAES technology to completely contribute in and ship a spectrum of meaningful grid services for markets.

Hydrostor’s A-CAES technology works by possessing electricity from the grid to function an air compressor, while generating heated and compressed air. From the stream, the heat is extracted  and stored to be used later. The cool compressed air afterwards goes t underground to a cavern (either pre-existing or built for the purpose). When the grid requires transmittable energy capacity, the air pulls back to the surface, re-allocates the storage heat, and flows through an air turbine, generating power.

Export Development Canada (EDC) supported the project. It received funding from Sustainable Development Technology Canada (SDTC). SDTC works with Canadian companies to bring clean technologies to market. In addition, Government of Ontario provided funding via the Ontario Centres of Excellence (OCE).

Earlier this month, the Goderich A-CAES Facility also received an Energy Storage North America Innovation Award. That shows its perfectness and leadership in energy storage and positive effect on the sector
