For this episode, it’s off to Texas for geothermal 2.0: geo‑pressured wells that act like batteries, storing grid power by pumping water deep underground and releasing it later for four to six hours of dispatchable energy. It’s a smart reuse of oilfield rigs, crews, and techniques, and it could help balance growing solar capacity as data centers surge into the state. The hurdles are cost and scale, but with familiar infrastructure and bipartisan momentum, this approach could become a key part of Texas’ energy mix.
