For energy storage? While this may seem unexpected, when it comes to cleantech innovation, you can expect the unexpected. SDTC-funded Hydrostor recently unveiled its impressive underwater compressed energy storage system – essentially, balloons filled with air under Lake Ontario, ready to release that air and spin turbines that would feed energy into the grid on an as-needed basis. The technology, developed with SDTC funding and in partnership with Toronto Hydro, officially went into operation on Wednesday. The results of this demonstration phase will serve to allow further developments to the technology and send it on its way to commercialization. Congratulations to Hydrostor on this remarkable achievement!
