Editor's note: It's a new week — start it strong with three quick things to catch up on in Houston's energy transition: an event not to miss, a Q&A to check out, and more.

Circular plastics project in Houston takes one more step toward becoming a reality

Cyclyx International, a joint venture that Houston-based ExxonMobil recently bought into with Agilyx and LyondellBasell, announced that it has made a final investment decision to build the first Cyclyx Circularity Center.

"This milestone is evidence of the real progress we are making to increase the circularity of plastic waste as a resource," Joe Vaillancourt, CEO of Cyclyx, says in a news release. "The first-of-its-kind CCC in Houston will serve as a blueprint, which we can replicate across the U.S. to progress our long-term goal of increasing the recycling options for plastic waste. Cyclyx is proud to be an innovator and enabler for unlocking plastic's potential."

Houston organizations ExxonMobil and LyondellBasell have committed $135 million into Cyclyx to fund operating activities and construction costs, which is expected to begin in mid-2025.

Event not to miss

Why Cindy Taff is betting on geothermal

There's no silver bullet to the energy transition, but Cindy Taff of Sage Geosystems is pretty positive geothermal energy is going to be a power player in the mix of technologies sure to make a difference. In a Q&A with EnergyCapital, she explains why she's so optimistic about geothermal and her company's technology — and why the traditional oil and gas industries should take note.

"My extensive experience in both geothermal and the O&G sector is a testament to the synergistic relationship between these industries. The skills honed in O&G are not only transferable—they are essential to advancing geothermal technologies," she tells EnergyCapital. She adds that "the O&G industry can make a huge impact to geothermal by systematically driving down costs while scaling up, which is exactly what we did for unconventional shales."
