Hey, it's Steven. I'm just popping into the feed to let you know that the Open Circuit crew is off this week. We will be back next week. In the meantime, if you're looking around the Internet for something to consume, you could go over to YouTube and subscribe to Latitude Media. There you can see our full episodes in video of Open Circuit and our other podcast, Catalyst with Shayl Khan will soon be on video. So if you are a watcher of podcasts and you do that on YouTube, definitely subscribe to Latitude Media for this week. I hope you enjoy this episode of the Green Blueprint. The Green Blueprint is a show with Laura Pierpoint as host. It is about the people architecting the clean economy. And we're in production now, so that's going to be back in March with a new season. This episode in particular is a really nice complement to our geothermal episode from a couple weeks ago. It features Cindy Taft, the CEO of Sage Geosystems. Cindy spent decades in oil and gas and is now building what she describes as pumped hydro flipped upside down. So instead of pumping water up a mountain, they're pumping it deep underground and using pressure in engineered fractures to store energy. It's part geothermal, part long duration storage and part oil field engineering experiment. They built their first commercial facility in about 13 months and then they ran straight into the grid interconnection wall, which for many of you who are developing projects might feel personal. So if you want a really grounded look at what it takes to build next generation geothermal and what still slows it down, look no further. So here's Lara Pierpoint with the Green Blueprint. I hope you enjoy and we'll see you next week.

Latitude Media covering the new frontiers of the energy transition. In 2022, Cindy Taft and her team at Sage Geosystems were fine tuning their gravity fracking technology in the field.

Our fracking technology, which is called gravity fracking, it allows you to frack downward toward the heat. But we also, after we created a fracture, we were cycling and testing that fracture on what was the best way to get the heat out of the ground without putting a lot of energy into the system.

Cindy's team has a background in oil and gas, but Sage Geosystems is taking that background and applying it to geothermal power. During this particular test, they realized that applying this fossil fuel technology to geothermal power generation might actually be a gateway to solving an even bigger challenge in the electricity industry.

It was during that testing that we also recognized that we had the perfect energy storage solution, which is like pump storage, but upside down, this is a big deal.
