Sage Geosystems' bet on underground energy storage
About 90% of global energy storage is pumped storage hydropower – which requires a mountain, a lake, and a whole lot of permitting. While lithium batteries have gotten drastically cheaper over the last decade, they’re still expensive for longer durations.
But Cindy Taff 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.
In this episode, Lara Pierpoint talks with Cindy Taff, CEO of Sage Geosystems about its groundbreaking new technology, their first commercial facility, and upcoming partnerships with geothermal giant Ormat Technologies.
Hosted by Lara Pierpoint. Produced and edited by Stephen Lacey and Anne Bailey. Technical direction by Sean Marquand. Stephen Lacey is our executive editor.
