Spring-based energy giant ExxonMobil has enlisted Air Liquide as a partner for what’s being billed as the world’s largest low-carbon hydrogen project.

The deal will enable transportation of ExxonMobil’s low-carbon hydrogen through Air Liquide’s pipeline network. Furthermore, Air Liquide will build and operate four units to supply 9,000 metric tons of oxygen and up to 6,500 metric tons of nitrogen each day for the ExxonMobil project.

Air Liquide’s U.S. headquarters is in Houston.

ExxonMobil’s hydrogen production facility is planned for the company’s 3,400-acre Baytown refining and petrochemical complex. The project is expected to produce 1 billion cubic feet of low-carbon hydrogen daily from natural gas and more than 1 million tons of low-carbon ammonia annually while capturing more than 98 percent of the associated carbon emissions.

“Momentum continues to build for the world’s largest low-carbon hydrogen project and the emerging hydrogen market,” Dan Ammann, president of ExxonMobil Low Carbon Solutions, says in a news release.

The hydrogen project is expected to come online in 2027 or 2028.

ExxonMobil says using hydrogen to fuel its olefins plant at Baytown could reduce sitewide carbon emissions by as much as 30 percent. Meanwhile, the carbon capture and storage (CSUS) component of the project would be capable of storing 10 million metric tons of carbon each year, the company says.

Texas joins in on lawsuit over rules on gas-powered trucks in California

road block

A large group of Republican attorneys general on Monday took legal action against the Biden administration and California over new emissions limits for trucks.

Nebraska Attorney General Mike Hilgers is leading the group of GOP attorneys general who filed a petition with the U.S. Court of Appeals for the District of Columbia Circuit to overturn an Environmental Protection Agency rule limiting truck emissions.

Texas joined Nebraska's latest action against the EPA, along with Alabama, Florida, Georgia, and several others.

A separate lawsuit against California claims a phased-in ban on internal-combustion trucks is unconstitutional and will hurt the U.S. economy.

Hilgers in a statement said the EPA and California rules “will devastate the trucking and logistics industry, raise prices for customers, and impact untold number of jobs across Nebraska and the country.”

“There’s not one trucking charging station in the state of Nebraska,” Hilgers later told reporters. “Trying to take that industry, which was built up over decades with diesel and fossil fuels-based infrastructure, and transforming it to an electric-based infrastructure – it’s probably not feasible.”

EPA officials have said the strict emissions standards will help clean up some of the nation’s largest sources of planet-warming greenhouse gases.

The new EPA rules are slated to take effect for model years 2027 through 2032, and the agency has said they will avoid up to 1 billion tons of greenhouse gas emissions over the next three decades.

Emissions restrictions could especially benefit an estimated 72 million people in the U.S. who live near freight routes used by trucks and other heavy vehicles and bear a disproportionate burden of dangerous air pollution, the agency has said.

A spokesperson for the EPA declined to comment on the legal challenge to the new rules Monday, citing the pending litigation.

California rules being challenged by Republican attorneys general would ban big rigs and buses that run on diesel from being sold in California starting in 2036.

An email seeking comment from California’s Air Resources Board was not immediately answered Monday.

California has been aggressive in trying to rid itself of fossil fuels, passing new rules in recent years to phase out gas-powered cars, trucks, trains and lawn equipment in the nation’s most populous state. Industries, and Republican leaders in other states, are pushing back.

Another band of GOP-led states in 2022 challenged California’s authority to set emissions standards that are stricter than rules set by the federal government. The U.S. Court of Appeals for the District of Columbia Circuit last month ruled that the states failed to prove how California’s emissions standards would drive up costs for gas-powered vehicles in their states.

Houston swerves onto new list of U.S. cities with the worst drivers

transportation

Locals may think that Houston is one of the most traffic-ridden cities, but its drivers are actually much better than many other U.S. cities, according to a new study by Forbes Advisor.

In its report "Cities With The Worst Drivers, Ranked," published February 8, Forbes Advisor analyzed the 50 most populated U.S. cities across five metrics to determine which have the worst drivers in the country. Those metrics, calculated per 100,000 city residents using a five-year average from 2017-2021, were: total number of fatal car accidents, number of people killed in fatal crashes, and number of fatal car accidents involving a drunk, distracted, or speeding driver.

Houston ranked No. 23 overall, earning a score of 59.27 points out of a possible 100. That means the drivers here are solidly average — and that other Texas cities' drivers are, amazingly, even worse than ours.

The report found approximately 10.81 total fatal crashes occur for every 100,000 city residents in Houston, with less than 12 people (11.36) killed in fatal crashes per 100,000 residents.

Where drunk drivers are involved, Houston ranked No. 9 for the highest per-capita number of fatal crashes. Fewer than five fatal drunk driving crashes (4.44) occurred per 100,000 residents.

This troubling discovery isn't exclusive to Houston, the state of Texas as a whole still struggles with drunk drivers. More than five people are killed in car crashes involving a drunk driver for every 100,000 Texans, according to a 2023 Forbes report.

Here's how Houston fared in the remaining categories:

  • No. 33 – Number of fatal crashes involving speeding (2.79 per 100,000 residents)
  • No. 40 – Number of fatal crashes involving a distracted driver (0.24 per 100,000 residents)
Forbes Advisor concluded that three of the top-15 U.S. cities with the worst drivers were located in Texas. Dallas (No. 6) earned a score of 90.97 points to take the crown for the city with the worst drivers in the state. Fort Worth (No. 9) also earned a top-10 spot, and San Antonio ranked No. 12. Austin fell behind Houston into No. 24.

The report found Dallas had the third-highest number of fatal car accidents involving a drunk driver, with 6.25 crashes per 100,000 residents. Dallas also ranked No. 4 in the category for the highest number of fatal car accidents involving speeding: 5.69 per 100,000 residents.

The most dangerous U.S. city to drive in, Forbes says, is Albuquerque, New Mexico. Albuquerque leads with the highest number of fatal car accidents involving a distracted driver, at 5.42 crashes per 100,000 city residents.

The top 10 U.S. cities with the worst drivers are:

  • No. 1 – Albuquerque, New Mexico
  • No. 2 – Memphis, Tennessee
  • No. 3 – Detroit, Michigan
  • No. 4 – Tuscon, Arizona
  • No. 5 – Kansas City, Missouri
  • No. 6 – Dallas, Texas
  • No. 7 – Louisville, Kentucky
  • No. 8 – Phoenix, Arizona
  • No. 9 – Fort Worth, Texas
  • No. 10 – Tampa, Florida

The study calculated five-year averages using data from the National Highway Traffic Safety Administration's Fatality and Injury Reporting System Tool for the years 2017-2021, and U.S. Census Bureau city population data from 2022.

Houston researcher earns $500,000 grant to tap into digital twin tech for bridge safety

transportation

A University of Houston professor has received a grant from the Texas Department of Transportation (TxDOT) to improve the efficiency and effectiveness of how bridges are inspected in the state.

The $505,286 grant will support the project of Vedhus Hoskere, assistant professor in the Civil and Environmental Engineering Department, over three years. The project, “Development of Digital Twins for Texas Bridges,” will look at how to use drones, cameras, sensors and AI to support Texas' bridge maintenance programs.

“To put this data in context, we create a 3D digital representation of these bridges, called digital twins,” Hoskere said in a statement. “Then, we use artificial intelligence methods to help us find and quantify problems to be concerned about. We’re particularly interested in any structural problems that we can identify - these digital twins help us monitor changes over time and keep a close eye on the bridge. The digital twins can be tremendously useful for the planning and management of our aging bridge infrastructure so that limited taxpayer resources are properly utilized.”

The project began in September and will continue through August 2026. Hoskere is joined on the project by Craig Glennie, the Hugh Roy and Lillie Cranz Cullen Distinguished Chair at Cullen College and director of the National Center for Airborne Laser Mapping, as the project’s co-principal investigator.

According to Hoskere, the project will have implications for Texas's 55,000 bridges (more than twice as many as any other state in the country), which need to be inspected every two years.

Outside of Texas, Hoskere says the project will have international impact on digital twin research. Hoskere chairs a sub-task group of the International Association for Bridge and Structural Engineering (IABSE).

“Our international efforts align closely with this project’s goals and the insights gained globally will enhance our work in Texas while our research at UH contributes to advancing bridge digitization worldwide,” he said. “We have been researching developing digital twins for inspections and management of various infrastructure assets over the past 8 years. This project provides us an opportunity to leverage our expertise to help TxDOT achieve their goals while also advancing the science and practice of better developing these digital twins.”

Last year another UH team earned a $750,000 grant from the National Science Foundation for a practical, Texas-focused project that uses AI. The team was backed by the NSF's Convergence Accelerator for its project to help food-insecure Texans and eliminate inefficiencies within the food charity system.

Houston researchers develop energy-efficient film for AI chips

AI research

A team of researchers at the University of Houston has developed an innovative thin-film material that they believe will make AI devices faster and more energy efficient.

AI data centers consume massive amounts of electricity and use large cooling systems to operate, adding a strain on overall energy consumption.

“AI has made our energy needs explode,” Alamgir Karim, Dow Chair and Welch Foundation Professor at the William A. Brookshire Department of Chemical and Biomolecular Engineering at UH, explained in a news release. “Many AI data centers employ vast cooling systems that consume large amounts of electricity to keep the thousands of servers with integrated circuit chips running optimally at low temperatures to maintain high data processing speed, have shorter response time and extend chip lifetime.”

In a report recently published in ACS Nano, Karim and a team of researchers introduced a specialized two-dimensional thin film dielectric, or electric insulator. The film, which does not store electricity, could be used to replace traditional, heat-generating components in integrated circuit chips, which are essential hardware powering AI.

The thinner film material aims to reduce the significant energy cost and heat produced by the high-performance computing necessary for AI.

Karim and his former doctoral student, Maninderjeet Singh, used Nobel prize-winning organic framework materials to develop the film. Singh, now a postdoctoral researcher at Columbia University, developed the materials during his doctoral training at UH, along with Devin Shaffer, a UH professor of civil engineering, and doctoral student Erin Schroeder.

Their study shows that dielectrics with high permittivity (high-k) store more electrical energy and dissipate more energy as heat than those with low-k materials. Karim focused on low-k materials made from light elements, like carbon, that would allow chips to run cooler and faster.

The team then created new materials with carbon and other light elements, forming covalently bonded sheetlike films with highly porous crystalline structures using a process known as synthetic interfacial polymerization. Then they studied their electronic properties and applications in devices.

According to the report, the film was suitable for high-voltage, high-power devices while maintaining thermal stability at elevated operating temperatures.

“These next-generation materials are expected to boost the performance of AI and conventional electronics devices significantly,” Singh added in the release.
