Sage Geo Systems

As the world rapidly transitions to intermittent renewable energy like wind and solar, the grid requires massive amounts of long-duration energy storage. However, traditional solutions like pumped hydro require specific mountainous terrain, and utility-scale lithium batteries remain incredibly expensive. After a 35-year career as an executive in the oil and gas industry, founder and CEO Cindy Taff realized that the exact same drilling technologies used to extract fossil fuels could be repurposed to unlock clean energy. She co-founded Sage Geosystems to turn the earth itself into a massive battery. Their breakthrough geopressured geothermal technology stores energy by pumping water deep underground; when grid demand spikes, the pressurized water is released to drive turbines and generate carbon-free electricity.

Cubit Capital invested in Sage Geosystems because it represents the ultimate stewardship of existing industry expertise while solving a fundamental, societal problem. By seamlessly transitioning oilfield technology and the skilled energy workforce toward sustainable power generation, Sage is building the resilient, baseload infrastructure necessary for a clean energy future.
