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, what to expect from the eclipse, and more.


Eyes on ERCOT amid eclipse

For three hours today, Texas' solar energy market will be affected by the solar eclipse. According to a report from the Environment Texas Research & Policy Center, Texas ranks third in the U.S. for residential solar power generation, so the moon's interception to the sunlight can be a real test to ERCOT, which reported that they have worked with solar forecast vendors on what to expect from solar generation on the grid during the eclipse.

"As we did in preparation for the October 2023 eclipse, ERCOT is actively monitoring the forecasts and available dispatchable capacity for April 8," reads a statement from the organization's March report. "ERCOT will rely on Ancillary Services and other actions to posture the system as necessary during the eclipse to compensate for both the reduction and increase in solar generation on this day and maintain grid reliability. ERCOT has been engaging Market Participants so that they are prepared for the eclipse and expects sufficient generation to meet demand."

Really big deal: Shell's EV charging plans

As it downshifts sales of fuel for traditional vehicles, energy giant Shell is stepping up its commitment to public charging stations for electric vehicles.

In a new report on energy transition, Shells lays out an aggressive plan for growing its public network of charging stations for electric vehicles (EVs). The company plans to boost the global number of public EV charging stations from about 54,000 today to around 70,000 by 2025 and about 200,000 by 2030.

The projected growth from today to 2030 would represent a 270 percent increase in the number of Shell-operated EV charging stations.

“We have a major competitive advantage in terms of locations, as our global network of service stations is one of the largest in the world,” Shell says in the report. Read the full story.

A research lab at the University of Houston has developed a new type of material for sodium-ion batteries that could make them more efficient and boost their energy performance.

Led by Pieremanuele Canepa, Robert Welch assistant professor of electrical and computer engineering at UH, the Canepa Research Laboratory is working on a new material called sodium vanadium phosphate, which improves sodium-ion battery performance by increasing the energy density. Energy density is the amount of energy stored per kilogram, and the new material can do so by more than 15 percent. With a higher energy density of 458 watt-hours per kilogram — compared to the 396 watt-hours per kilogram in older sodium-ion batteries — this material brings sodium technology closer to competing with lithium-ion batteries, according to the researchers.

The Canepa Lab used theoretical expertise and computational methods to discover new materials and molecules to help advance clean energy technologies. The team at UH worked with the research groups headed by French researchers Christian Masquelier and Laurence Croguennec from the Laboratoire de Reáctivité et de Chimie des Solides, which is a CNRS laboratory part of the Université de Picardie Jules Verne, in Amiens France, and the Institut de Chimie de la Matière Condensée de Bordeaux, Université de Bordeaux, Bordeaux, France for the experimental work on the project.

The researchers then created a battery prototype using the new materia sodium vanadium phosphate, which demonstrated energy storage improvements. The material is part of a group called “Na superionic conductors” or NaSICONs, which is made to let sodium ions move in and out of the battery during charging and discharging.

“The continuous voltage change is a key feature,” Canepa says in a news release. “It means the battery can perform more efficiently without compromising the electrode stability. That’s a game-changer for sodium-ion technology.”

The synthesis method used to create sodium vanadium phosphate may be applied to other materials with similar chemistries, which could create new opportunities for advanced energy storage. A paper of this work was published in the journal Nature Materials.

"Our goal is to find clean, sustainable solutions for energy storage," Canepa adds. "This material shows that sodium-ion batteries can meet the high-energy demands of modern technology while being cost-effective and environmentally friendly."
