The Green Blueprint: Sage Geosystems' bet on underground energy storage

This week, we’re featuring an episode of The Green Blueprint.  In this episode, Lara Pierpoint talks with Cindy Taff, CEO of Sage Geosystems. Cindy and her team at Sage Geosystems are developing geothermal technology that could revolutionize energy storage. Instead of pumping water up a mountain, they pump it deep into the earth, providing cost-effective, long-term storage for intermittent renewable sources.  They’re piloting this technology at a new commercial facility in partnership with  San Miguel Electric Cooperative, a rural Texas electric cooperative that is transitioning from coal to solar and battery storage thanks to a USDA grant.  Lara and Cindy talk about Sage’s groundbreaking new technology, its first commercial facility, and upcoming partnerships with geothermal giant Ormat Technologies.  If you are looking for more Open Circuit episodes to consume, subscribe to Latitude’s YouTube page.  Explore the new era of AI innovation in the fifth season of Where the Internet Lives, an award-winning podcast from Google and Latitude Studios.
