Katie Mehnert started ALLY Energy — originally founded as Pink Petro — to move forward DEI initiatives, and she says she started with building an audience first and foremost, but now the technology part of the platform has fallen into place too. Last summer, ALLY Energy acquired Clean Energy Social, which meant doubling its community while also onboarding new technology. On the episode, Mehnert reveals that this new website and platform is now up and running.

"We launched the integrated product a few weeks back," Mehnert says. "The whole goal was to move away from technology that wasn't serving us."

Now, moving into the new year, Mehnert is building the team the company needs. She says she hopes to grow ALLY from two employees to 10 by the end of the year and is looking for personnel within customer support, product developers, and sales and service. While ALLY is revenue generating, she also hopes to fundraise to further support scaling. Click here to read more.

The state of Texas is about a month away from the one year anniversary of Winter Storm Uri — but is the state better prepared this winter season? Don Whaley, president at OhmConnect Texas, looked at where the state is now versus then in a guest column for InnovationMap.

"Governor Abbott has gone on record guaranteeing that the lights will stay on this winter, and I am inclined to agree. With the reinforcement of our fuel systems being mandated by the Railroad Commission, 2023 to 2025 should receive the same guarantee," he writes. "Beyond that, as the demand for electricity in Texas continues to grow, we will need to rely on the initiatives under consideration by the PUCT to attract investment and innovation in new, dispatchable generation and flexible demand solutions to ensure long-term stability in the ERCOT market.

Whaley has worked for over 40 years in the natural gas, electricity, and renewables industries, with specific experience in deregulated markets across the U.S. and Canada. He founded Direct Energy Texas and served as its president during the early years of deregulation. Click here to read more.

Opinion: Houston energy expert weighs in on if the state's power grid is ready for winter

guest column

The Winter Storm Uri, which struck Texas in February of 2021, was an unprecedented event in both severity and duration. At its most extreme, temperatures were as much as 40 to 50 degrees below their historic averages. The storm resulted in the largest controlled blackout in U.S. history, forcing the shedding of more than 23 gigawatts of load, the loss of power to 4.5 million homes and businesses for periods of one to four days, and the tragic loss of hundreds of lives.

A crisis of this magnitude has resulted in an intense re-examination of the Texas power grid. Not surprisingly, it has also resulted in record levels of finger-pointing and an ongoing search to identify the parties responsible. Among the casualties were all three Public Utility Commissioners that regulate the industry and a virtual purge of ERCOT, the organization that operates and manages the grid.

The Texas 87th Legislature filed an inordinate number of bills to address the electric system's failings, and Governor Abbott’s office has been vocal and actively working to ensure that there will never again be a repeat of the events of February 2021. The principal focus of the now reconstituted and expanded Public Utility Commission of Texas (PUCT) has been defining and implementing changes to system rules and operations in order to extract a greater degree of reliability from existing assets and incentivize the construction of significantly more MW of dispatchable generation. Many of the changes implemented by the PUCT will provide the market with a greater cushion against shocks to the system, moving the market away from a crisis management mode and towards a more proactive footing. We can expect even more change once current policies are assessed and more aggressive proposals are analyzed to determine whether they offer more benefit than harm to the market.

Amid all the debate, discussion, and wringing of hands, only one report has come close to identifying the smoking gun at the center of the crisis: the need for weatherization. The notion that weatherizing of generating assets is the key to future reliability has been discussed ad nauseum, but the report issued by the Federal Energy Regulatory Commission on November 16, 2021, attributes an equal share of the blame to the natural gas producing, processing, and transportation sector and its inability to perform reliably under the harsh conditions of Uri.

In the areas affected worst by the storm, gas production in Texas, Oklahoma, and Louisiana fell by more than 50 percent at its lowest point when compared to average production in the prior month. The Railroad Commission, not the Public Utility Commission, regulates natural gas transmission, and it was slow off the mark given the focus on generation. The Railroad Commission has now begun to implement weatherization requirements, with new initiatives slated to be in full effect for the winter of 2023.

It is imprudent to use “never” as a time scale, but I would place the probability at “remote” that Texas will see a recurrence of the events of February 2021 in 2022. In the unlikely event we did, the impacts would likely pale in comparison to those experienced last February. This is due both to the heightened state of preparedness with which the industry will approach the coming winter and the impact of changes put into effect by the PUCT as of January 1, 2022.

Governor Abbott has gone on record guaranteeing that the lights will stay on this winter, and I am inclined to agree. With the reinforcement of our fuel systems being mandated by the Railroad Commission, 2023 to 2025 should receive the same guarantee. Beyond that, as the demand for electricity in Texas continues to grow, we will need to rely on the initiatives under consideration by the PUCT to attract investment and innovation in new, dispatchable generation and flexible demand solutions to ensure long-term stability in the ERCOT market.

Houston team’s discovery brings solid-state batteries closer to EV use

A Better Battery

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.

University of Houston archaeologists make history with Mayan tomb discovery

History in the Making

Two University of Houston archaeologists have made scientific history with the discovery of a Mayan king's tomb in Belize.

The UH team led by husband and wife scientists Arlen F. Chase and Diane Z. Chase made the discovery at Caracol, the largest Mayan archeological site in Belize, which is situated about 25 miles south of Xunantunich and the town of San Ignacio. Together with Belize's Institute of Archeology, as well as support from the Geraldine and Emory Ford Foundation and the KHR Family Fund, they uncovered the tomb of Caracol's founder, King Te K’ab Chaak. Their work used airborne light detection and ranging technology to uncover previously hidden roadways and structures that have been reclaimed by the jungle.

The tomb was found at the base of a royal family shrine. The king, who ascended the throne in 331 AD, lived to an advanced enough age that he no longer had teeth. His tomb held a collection of 11 pottery vessels, carved bone tubes, jadeite jewelry, a mosaic jadeite mask, Pacific spondylus shells, and various other perishable items. Pottery vessels found in the chamber depict a Maya ruler wielding a spear as he receives offerings from supplicants represented as deities; the figure of Ek Chuah, the Maya god of traders, surrounded by offerings; and bound captives, a motif also seen in two related burials. Additionally, two vessels had lids adorned with modeled handles shaped like coatimundi (pisote) heads. The coatimundi, known as tz’uutz’ in Maya, was later adopted by subsequent rulers of Caracol as part of their names.

During the Classical Period, Caracol was one of the main hubs of the Mayan Lowlands and covered an area bigger than that of present-day Belize City. Populations survived in the area for at least 1,000 years before the city was abandoned sometime around 900 AD. The royal dynasty established by Te K’ab Chaak continued at Caracol for over 460 years.

The find is also significant because this was roughly when the Mexican city of Teotihuacan made contact with Caracol, leading to a long relationship of trade and cultural exchange. Cremation sites found in Caracol contain items that would have come from Teotihuacan, showing the relationship between the two distant cities.

"Both central Mexico and the Maya area were clearly aware of each other’s ritual practices, as reflected in the Caracol cremation," said Arlen F. Chase, professor and chair of Comparative Cultural Studies at the University of Houston.

“The connections between the two regions were undertaken by the highest levels of society, suggesting that initial kings at various Maya cities — such as Te K’ab Chaak at Caracol — were engaged in formal diplomatic relationships with Teotihuacan.”

The Chases will present their findings at a conference on Maya–Teotihuacan interaction hosted by the Maya Working Group at the Santa Fe Institute in New Mexico in August 2025.
