Katherine Peretick at NRStor project in Goderich low res copyKATHERINE PERETICK, a top electricity storage expert works with one of Canada’s most progressive energy companies, NRStor. She holds a Masters in mechanical engineering, and has worked at Nasa in California, Vestas in Denmark, GM and General Compression in Detroit. She is developing one of the most exciting compressed air energy storage projects (CAES) projects in the world, in Goderich, Ontario. Most people think of batteries when they think of storing solar power for use after sunset or wind power generated at night for peak daytime periods; but compressed air is a much less expensive and promising alternative at the moment. Most compressed air facilities around the world use some fossil fuel, but this new project and future ones for this company are fossil fuel free.
