Maria Gallucci of Canary Media reports on a Texas geothermal startup that is storing energy underground.
- Sage Geosystems is a Texas geothermal startup that is looking to advance geothermal energy storage.
- The process works by pumping water into underground wells of depleted oil and gas reserves and releasing the water to spin a turbine and generate electricity.
- The company estimates that pumping 5,000 barrels of water would produce 200 kilowatts of electricity during a 5 hour stretch.
“The startup installed a ground-level storage facility that holds some 30,000 barrels (1.26 million gallons) of water, the source for which is a nearby private water well. Sage pumps water into the fracture in various volumes and measures the water’s flow rate — or how many barrels are moving through the well per minute. Computer models use the data gathered during testing to simulate how much electricity the site could discharge, like a battery, over certain periods of time.”
