Editor's note: Dive headfirst into the new week with three quick things to catch up on in Houston's energy transition.

Hurricane Beryl's big impact

Hundreds of thousands of people in the Houston area likely won’t have power restored until this week, as the city swelters in the aftermath of Hurricane Beryl.

The storm slammed into Texas on July 8, knocking out power to nearly 2.7 million homes and businesses and leaving huge swaths of the region in the dark and without air conditioning in the searing summer heat.

Although repairs have restored power to nearly 1.4 million customers, the scale of the damage and slow pace of recovery has put CenterPoint Energy, which provides electricity to the nation's fourth-largest city, under mounting scrutiny over whether it was sufficiently prepared for the storm and is doing enough now to make things right.

Some frustrated residents have also questioned why a part of the country that is all too familiar with major storms has been hobbled by a Category 1 hurricane, which is the weakest kind. But a storm's wind speed, alone, doesn't determine how dangerous it can be. Click here to continue reading this article from the AP.

Big deal: Devon Energy to acquire Houston exploration, production biz in $5B deal

Devon Energy is buying Grayson Mill Energy's Williston Basin business in a cash-and-stock deal valued at $5 billion as consolidation in the oil and gas sector ramps up.

The transaction includes $3.25 billion in cash and $1.75 billion in stock.

Grayson Mill Energy, based in Houston, is an oil and gas exploration company that received an initial investment from private equity firm EnCap Investments in 2016.

The firm appears to be stepping back from energy sector as it sells off assets. Last month EnCap-backed XCL Resources sold its Uinta Basin oil and gas assets to SM Energy Co. and Northern Oil and Gas in a transaction totaling $2.55 billion. EnCap had another deal in June as well, selling some assets to Matador Resources for nearly $2 billion. Click here to continue reading.

A View From HETI

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.”
