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 geothermal company raises $97M Series B

fresh funding

Houston-based geothermal energy startup Sage Geosystems has closed its Series B fundraising round and plans to use the money to launch its first commercial next-generation geothermal power generation facility.

Ormat Technologies and Carbon Direct Capital co-led the $97 million round, according to a press release from Sage. Existing investors Exa, Nabors, alfa8, Arch Meredith, Abilene Partners, Cubit Capital and Ignis H2 Energy also participated, as well as new investors SiteGround Capital and The UC Berkeley Foundation’s Climate Solutions Fund.

The new geothermal power generation facility will be located at one of Ormat Technologies' existing power plants. The Nevada-based company has geothermal power projects in the U.S. and numerous other countries around the world. The facility will use Sage’s proprietary pressure geothermal technology, which extracts geothermal heat energy from hot dry rock, an abundant geothermal resource.

“Pressure geothermal is designed to be commercial, scalable and deployable almost anywhere,” Cindy Taff, CEO of Sage Geosystems, said in the news release. “This Series B allows us to prove that at commercial scale, reflecting strong conviction from partners who understand both the urgency of energy demand and the criticality of firm power.”

Sage reports that partnering with the Ormat facility will allow it to market and scale up its pressure geothermal technology at a faster rate.

“This investment builds on the strong foundation we’ve established through our commercial agreement and reinforces Ormat’s commitment to accelerating geothermal development,” Doron Blachar, CEO of Ormat Technologies, added in the release. “Sage’s technical expertise and innovative approach are well aligned with Ormat’s strategy to move faster from concept to commercialization. We’re pleased to take this natural next step in a partnership we believe strongly in.”

In 2024, Sage agreed to deliver up to 150 megawatts of new geothermal baseload power to Meta, the parent company of Facebook. At the time, the companies reported that the project's first phase would aim to be operating in 2027.

The company also raised a $17 million Series A, led by Chesapeake Energy Corp., in 2024.

Houston expert discusses the clean energy founder's paradox

Guest Column

Everyone tells you to move fast and break things. In clean energy, moving fast without structural integrity means breaking the only planet we’ve got. This is the founder's paradox: you are building a company in an industry where the stakes are existential, the timelines are glacial, and the capital requires patience.

The myth of the lone genius in a garage doesn’t really apply here. Clean energy startups aren’t just fighting competitors. They are fighting physics, policy, and decades of existing infrastructure. This isn’t an app. You’re building something physical that has to work in the real world. It has to be cheaper, more reliable, and clearly better than fossil fuels. Being “green” alone isn’t enough. Scale is what matters.

Your biggest risks aren’t competitors. They’re interconnection delays, permitting timelines, supply chain fragility, and whether your first customer is willing to underwrite something that hasn’t been done before.

That reality creates a brutal filter. Successful founders in this space need deep technical knowledge and the ability to execute. You need to understand engineering, navigate regulation, and think in terms of markets and risk. You’re not just selling a product. You’re selling a future where your solution becomes the obvious choice. That means connecting short-term financial returns with long-term system change.

The capital is there, but it’s smarter and more demanding. Investors today have PhDs in electrochemistry and grid dynamics. They’ve been burned by promises of miracle materials that never left the lab. They don't fund visions; they fund pathways to impact that can scale and make financial sense. Your roadmap must show not just a brilliant invention, but a clear, believable plan to drive costs down over time.

Capital in this sector isn’t impressed by ambition alone. It wants evidence that risk is being retired in the right order — even if that means slower growth early.

Here’s the upside. The difficulty of clean energy is also its strength. If you succeed, your advantage isn’t just in software or branding. It’s in hardware, supply chains, approvals, and years of hard work that others can’t easily copy. Your real competitors aren’t other startups. They’re inertia and the existing system. Winning here isn’t zero-sum. When one solution scales, it helps the entire market grow.

So, to the founder in the lab, or running field tests at a remote site: your pace will feel slow. The validation cycles are long. But you are building in the physical world. When you succeed, you don’t have an exit. You have a foundation. You don't just have customers; you have converts. And the product you ship doesn't just generate revenue; it creates a legacy.

If your timelines feel uncomfortable compared to software, that’s because you’re operating inside a system designed to resist change. And let’s not forget you are building actual physical products that interact with a complex world. Times are tough. Don’t give up. We need you.

Houston maritime startup raises $43M to electrify cargo vessels

A Houston-based maritime technology company that is working to reduce emissions in the cargo and shipping industry has raised VC funding and opened a new Houston headquarters.

Fleetzero announced that it closed a $43 million Series A financing round this month led by Obvious Ventures with participation from Maersk Growth, Breakthrough Energy Ventures, 8090 Industries, Y Combinator, Shorewind, Benson Capital and others. The funding will go toward expanding manufacturing of its Leviathan hybrid and electric marine propulsion system, according to a news release.

The technology is optimized for high-energy and zero-emission operation of large vessels. It uses EV technology but is built for maritime environments and can be used on new or existing ships with hybrid or all-electric functions, according to Fleetzero's website. The propulsion system was retrofitted and tested on Fleetzero’s test ship, the Pacific Joule, and has been deployed globally on commercial vessels.

Fleetzero is also developing unmanned cargo vessel technology.

"Fleetzero is making robotic ships a reality today. The team is moving us from dirty, dangerous, and expensive to clean, safe, and cost-effective. It's like watching the future today," Andrew Beebe, managing director at Obvious Ventures, said in the news release. "We backed the team because they are mariners and engineers, know the industry deeply, and are scaling with real ships and customers, not just renderings."

Fleetzero also announced that it has opened a new manufacturing and research and development facility, which will serve as the company's new headquarters. The facility features a marine robotics and autonomy lab, a marine propulsion R&D center and a production line with a capacity of 300 megawatt-hours per year. The company reports that it plans to increase production to three gigawatt-hours per year over the next five years.

"Houston has the people who know how to build and operate big hardware–ships, rigs, refineries and power systems," Mike Carter, co-founder and COO of Fleetzero, added in the release. "We're pairing that industrial DNA with modern batteries, autonomy, and software to bring back shipbuilding to the U.S."
