Editor's note: Dive headfirst into the new week with three quick things to catch up on in Houston's energy transition: a roundup of events not to miss, a one-on-one with Barbara Burger, and more.

Podcast to stream: A conversation with Barbara Burger

Last month, Barbara Burger participated in four panels at CERAWeek by S&P Global, and from her insider perspective, she had a few key takeaways from the event, which brought together energy leaders, tech startups, dignitaries, civil servants, and more.

In a recent podcast interview, Burger shared some of her key takeaways from the event — and how these trends are affecting the industry as a whole.

Report: Texas as a green state needs improvement

A new report from WalletHub looked at 25 key metrics — from green buildings per capita to energy consumption from renewable resources — to evaluate the current health of states' environment and residents’ environmental-friendliness. Texas ranked No. 38, meaning it was the thirteenth least green state, only scoring 50.40 points out of 100.

Here's how Texas ranked among a few of the key metrics:

  • No. 35 for air quality
  • No. 38 for soil quality
  • No. 38 for water quality
  • No. 26 for LEED-certified buildings per capita
  • No. 32 for percent of renewable energy consumption
  • No. 45 for energy consumption per capita
  • No. 38 for gasoline consumption (in gallons) per capita

Battery breakthrough

Houston scientists unveil faster, low-energy method to recycle lithium-ion batteries

Rice University researchers have uncovered a more energy-efficient and faster way to recycle critical minerals from used lithium-ion batteries.

Traditional methods rely on high heat, long processing times and harsh chemicals to recover a small fraction of critical materials from batteries used in everything from smartphones to electric vehicles. However, the team from Rice's Department of Materials Science and Nanoengineering developed a process that uses a water-based solution containing amino chlorides to extract more metals in less time

The team published the findings in a recent edition of the scientific journal Small.

Simon King, a sophomore studying chemical and biomolecular engineering who completed this work as a summer research fellow at the Rice Advanced Materials Institute, served as first author of the study. He worked with corresponding authors Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor of Engineering, and Sohini Bhattacharyya, a research scientist in Ajayan’s lab.

By using a hydroxylammonium chloride (HACI) solution, the team achieved roughly 65 percent extraction of key battery metals in just one minute at room temperature, according to the study. The efficiencies grew to roughly 75 percent for several metals under longer processing times.

“We were surprised by just how fast the reaction occurs, especially without the involvement of high temperatures,” King said in a news release. “Within the first minute, we’re already seeing the majority of the metal extraction take place.”

By not requiring high temperatures or long reaction times, Rice predicts the process could have a major impact on cost and the environmental impact of lithium battery recycling. Additionally, the water-based HACI solution makes waste handling easier and lowers certain environmental risks.

In addition to extracting the materials, the team went on to demonstrate that the recovered metals could be recycled and reprocessed into new battery materials.

“A big advantage of this system is that it works under relatively mild conditions,” Ajayan added in the release. “That opens the door to more sustainable and scalable recycling technologies.”
