Editor's note: It's a new week — start it strong with three quick things to know in Houston's energy transition ecosystem: events not to miss, robotaxis take a break, and more.

Events this week

Don't miss these two events.

  • November 7-8: Hydrogen North America 2024 will host the hydrogen sector's thought leaders for a two-day event. Learn more.
  • November 8 — The Houston Innovation Awards will honor the city's startups, entrepreneurs, and ecosystem, including energy tech innovators. Learn more.

Cruise hits the brakes

Self-driving taxi service, Cruise, which recently launched in Houston, has put it in park for the time being, as TechCrunch reported last month.

The company's California permit was rescinded, and Cruise announced a national pause on its service in a statement.

"The most important thing for us right now is to take steps to rebuild public trust. Part of this involves taking a hard look inwards and at how we do work at Cruise, even if it means doing things that are uncomfortable or difficult," reads the statement. "In that spirit, we have decided to proactively pause driverless operations across all of our fleets while we take time to examine our processes, systems, and tools and reflect on how we can better operate in a way that will earn public trust. This is not related to any new on-road incidents, and our supervised AV operations will continue."

Meet LYB — and its latest sustainability deal

LyondellBasell has rebranded as LYB, revealing a new logo, tagline, and visual identity.

“With our new strategy firmly in place, our employees are adopting new ways of working to generate innovative, value-enhancing solutions to support our goals,” Peter Vanacker, LYB's CEO, says in the release.

The Dutch company, whose U.S. headquarters is in Houston, also recently announced that it has purchased a 25 percent stake in a joint venture that seeks to accelerate advancements in plastic recycling.

A team of researchers from the University of Houston, Rice University and Brown University has uncovered new findings that could extend battery life and potentially change the electric vehicle landscape.

The team, led by Yan Yao, the Hugh Roy and Lillie Cranz Cullen Distinguished Professor of Electrical and Computer Engineering at UH, recently published its findings in the journal Nature Communications.

The work deployed a powerful, high-resolution imaging technique known as operando scanning electron microscopy to better understand why solid-state batteries break down and what could be done to slow the process.

“This research solves a long-standing mystery about why solid-state batteries sometimes fail,” Yao, corresponding author of the study, said in a news release. “This discovery allows solid-state batteries to operate under lower pressure, which can reduce the need for bulky external casing and improve overall safety.”

A solid-state battery replaces liquid electrolytes found in conventional lithium-ion cells with a solid separator, according to Car and Driver. They also boast faster recharging capabilities, better safety and higher energy density.

However, when it comes to EVs, solid-state batteries are not ideal since they require high external stack pressure to stay intact while operating.

Yao’s team learned that tiny empty spaces, or voids, form within the solid-state batteries and merge into a large gap, which causes them to fail. The team found that adding small amounts of alloying elements, like magnesium, can help close the voids and help the battery continue to function. The team captured it in real-time with high-resolution videos that showed what happens inside a battery while it’s working under a scanning electron microscope.

“By carefully adjusting the battery’s chemistry, we can significantly lower the pressure needed to keep it stable,” Lihong Zhao, the first author of this work, a former postdoctoral researcher in Yao’s lab and now an assistant professor of electrical and computer engineering at UH, said in the release. “This breakthrough brings solid-state batteries much closer to being ready for real-world EV applications.”

The team says it plans to build on the alloy concept and explore other metals that could improve battery performance in the future.

“It’s about making future energy storage more reliable for everyone,” Zhao added.

The research was supported by the U.S. Department of Energy’s Battery 500 Consortium under the Vehicle Technologies Program. Other contributors were Min Feng from Brown; Chaoshan Wu, Liqun Guo, Zhaoyang Chen, Samprash Risal and Zheng Fan from UH; and Qing Ai and Jun Lou from Rice.
