Energy giant Exxon Mobil Corp. has set a date to move its legal headquarters to Texas.

The Spring-based company announced this week that the redomiciliation from New Jersey to Texas is expected to be effective July 1. Exxon's board of directors unanimously recommended redomiciling in the Lone Star State in March, and shareholders approved the move to Texas at the company’s annual meeting in May.

As part of the move, ExxonMobil Holdings Corp. will replace Exxon Mobil Corp. of New Jersey and become the publicly traded parent company. Exxon reports that its shares will continue to trade on the New York Stock Exchange under the ticker symbol “XOM,” and that shareholders do not need to take action.

At the time of the recommendation, Exxon said the move would not affect business operations, management, strategy, assets or employee locations.

Exxon Chairman and CEO Darren Woods added that the redomiciliation was in part due to Texas' business-friendly environment and policies.

"Over the past several years, Texas has made a noticeable effort to embrace the business community. In doing so, it has created a policy and regulatory environment that can allow the company to maximize shareholder value,” Woods said in a news release. "Aligning our legal home with our operating home, in a state that understands our business and has a stake in the company’s success, is important.”

The Associated Press reports that about 30 percent of Exxon's employees work in Texas. Exxon's legal headquarters has been based in New Jersey since 1882, when it was Standard Oil Company.

Exxon moved its operational headquarters from Irving, Texas, to the Houston area in 2023.

Exxon was the highest-ranking Houston-area company on this year's Fortune 500 list, coming in at No. 9. Houston tied with Chicago for the second-most Fortune 500 headquarters on this year's list, with Texas leading the nation for the most Fortune 500 headquarters (57).

“Texas is the undisputed headquarters of headquarters,” Gov. Greg Abbott said in a news release. “The world’s leading businesses invest with confidence in Texas because of our welcoming business climate, predictable regulatory environment, and skilled and growing workforce. People and businesses are choosing Texas because Texas works.”

Fourteen businesses with global or regional headquarters in the Houston area appear on Fortune’s new list of the world’s 500 biggest companies.

Oil and gas company Saudi Aramco, whose headquarters for the Americas is in Houston, leads the Houston-area pack. With annual revenue of $494.9 billion, it lands at No. 4 on the Fortune Global 500. Ahead of Saudi Aramco are U.S. retailers Walmart and Amazon, and Chinese electric company State Grid.

To put Saudi Aramco’s annual revenue in perspective, the total is slightly above the gross domestic product for the Philippines.

For the third year in a row, Saudi Aramco stands out as the most profitable member of the Fortune Global 500. The company racked up $121 billion in profit last year.

Overall, Saudi Aramco and 32 other petroleum refiners — many of them with a significant presence in the Houston area — made the Fortune Global 500.

“The Global 500 is the ultimate scorecard for business success. The aggregate revenue of the Fortune Global 500 in 2023 reached $41 trillion, a record level. That sum represents more than a third of global GDP — a sign of how much economic power is concentrated in these companies,” Scott DeCarlo, Fortune’s vice president of research, says in a news release.

Here’s the rundown of Fortune Global 500 companies with global or regional headquarters in the Houston area, including the ranking and annual revenue for each:

  • Saudi Aramco, No. 4, $494.9 billion, Americas headquarters in Houston
  • ExxonMobil, No. 12, $344.6 billion, global headquarters in Spring

Following years of speculation, Chevron announces HQ move to Houston

big news

The Energy Capital of the World is adding another jewel to its corporate crown.

With the impending move of Chevron’s headquarters from Northern California to Houston, the Houston area will be home to 24 Fortune 500 companies. Chevron ranks 15th on this year’s Fortune 500.

Oil and gas giant Chevron, currently based in San Ramon, California, will join three Fortune 500 competitors that already maintain headquarters in the Houston area:

  • Spring-based ExxonMobil, No. 7 on the Fortune 500
  • Houston-based Phillips 66, No. 26 on the Fortune 500
  • Houston-based ConocoPhillips, No. 68 on the Fortune 500

Chevron, which posted revenue of $200.9 billion in 2023, employs about 7,000 people in the Houston area and about 2,000 people in San Ramon. The company says its chairman and CEO, Mike Wirth, and vice chairman, Mark Nelson, will move to Houston before the end of 2024.

In an interview with The Wall Street Journal, Wirth acknowledged Chevron’s differences of opinion with California policymakers regarding energy matters.

“We believe California has a number of policies that raise costs, that hurt consumers, that discourage investment and ultimately we think that’s not good for the economy in California and for consumers,” Wirth said.

Chevron expects all of its corporate functions to shift to Houston over the next five years. Jobs that support the company’s California operations will remain in San Ramon, where Chevron employs about 2,000 people. Some Chevron employees in San Ramon will relocate to Houston.

The company’s move to Houston hardly comes as a surprise. Speculation about a relocation to Houston intensified after Chevron sold its 98-acre San Ramon headquarters in 2022 and moved corporate employees to leased office space. Over the past several years, Chevron has shifted various corporate functions to Houston.

“This is just the final step that many industry observers were waiting to happen,” Ken Medlock, senior director of the Baker Institute’s Center for Energy Studies at Rice University, says in a news release.

“To start, Houston provides a world-class location for internationally focused energy companies, which is why there is such a massive international presence here,” Medlock adds. “Texas is also the nation’s largest energy producer across multiple energy sources and is poised to lead in emerging opportunities such as hydrogen and carbon capture, so Houston is a great place for domestically focused activities as well.”

The announcement of Chevron’s exit from California comes just a year after ExxonMobil finalized its relocation from Irving to Spring.

“Chevron’s decision to relocate its headquarters underscores the compelling advantages that position Houston as the prime destination for leading energy companies today and for the future,” Steve Kean, president and CEO of the Greater Houston Partnership, says in a post on the organization’s website.

“With deep roots in our region,” he adds, “Chevron is [a] key player in establishing Houston as a global energy leader. This move will further enhance those efforts.”

Energy AI startup chooses Houston for first U.S. office after $20M raise

welcome to houston

London-based AI firm Applied Computing has announced a $20 million Series A round and a new office in Houston.

The new Bayou City office is Applied Computing’s first in the United States and part of its North American expansion. The company is known for its Orbital AI platform, which is tailored for energy operations.

The funding round was led by Houston-based KBR Inc., with participation from San Francisco-based Databricks Ventures. KBR’s investment was first announced in March.

KBR and Applied Computing have also entered into a multi-year agreement to deliver exclusive AI products for the energy sector. KBR already has integrated Orbital into its INSITE 3.0 platform for energy projects, and is also using the product for ammonia production.

Applied Computing’s Orbital platform combines physics-grounded intelligence with models across chemical engineering, time-series forecasting and language, according to the company. The system analyzes sensor readings and can recognize a facility’s equipment constraints and operator activity. The platform can also allow technicians to run simulations of how a change to a facility could affect the rest of its operations.

According to TechCrunch, Applied Computing will use the $20 million to further explore projects and deployments with the energy sector, hire engineering and research positions, and continue to expand internationally, potentially into the Middle East.

The company is also working on deals with a major U.S. stream operator, TechCrunch reports. And Applied Computing shared on LinkedIn that it plans to announce its first partnership with a major European oil company in the coming weeks.

“Yesterday we showed Orbital live in deployments at our demo day at the Energy Institute in London,” Callum Adamson, CEO and co-founder of Applied Computing, posted on LinkedIn on July 16. “Today, we're announcing the capital to scale it globally as well as the launch of our new offices in Houston and Bangalore. In the weeks following, there will be more announcements on our progress, partnerships and deployments.”

The company opened its Bangalore offices in December.

Automakers enter the energy space with vehicles offering backup power

Power Boost

Winter Storm Uri, the multiday freeze that slammed Texas in February 2021 and pummeled the state's power grid, has been on Kenneth Kovar's mind ever since. Though the resident of New Braunfels didn't lose power at the time, he wasn't able to run his septic tank — it is independent from local systems. He had to fill his toilets with water from his backyard pool.

So when Kovar, 64, bought a Ford F-150 last fall, his hope was to be better prepared for any new crisis.

“I was interested in trying to find some sort of power backup situation,” he said.

Now, Kovar has a setup from Ford that allows drivers of certain F-150 models to plug their vehicle directly into their electric meter to power parts of their home during an outage.

It is the latest example of automakers broadly adapting their electrification technologies to the home energy business, especially as demand on the grid increases and sales of electric vehicles slow. Car companies are looking to leverage their multibillion dollar EV investments to tap into a promising market in vehicle, home and grid technology, both for backup power and for supporting electrical grid resiliency.

“They’re trying to look for other businesses that they might sell into,” said Parth Vaishnav, assistant professor of sustainable systems at the University of Michigan.

Ford's latest connects F-150 drivers to their meter

Drivers of the F-150 PowerBoost hybrid and F-150 Lightning electric pickup trucks can now plug in a one-foot long adapter to a 240-volt outlet onboard. That adapter — which Ford made with company Global Power Products — makes the vehicle compatible to plug into a longer, separate cable. That cable connects to a transfer switch installed directly on one's electric meter.

Through the adapter and cable series, homeowners can connect their vehicle essentially right to their home’s breaker box. The homeowner simply turns on and off which breaker switches they want for which devices they want powered.

“The way we think about it, especially for customers who already have a compatible vehicle is, you already own the power source, it’s in your driveway,” said Amanda Roraff, Ford's grid and energy services business acceleration lead.

The Lightning might provide power for two to three days, depending on what home devices are being used, and the PowerBoost Hybrid, up to five days on a single tank of gas.

The automaker says its solution is a less expensive way to supply backup power. Conventional, diesel-powered portable generators and full-home standby setups require expensive installation, costing several thousands of dollars. This solution, which also requires professional installation at the meter, starts around $1,100.

The setup only applies to about 200,000 vehicles so far, and it is also exclusively for outages. Ford also offers its Home Integration System for bidirectionality, sending power both from the vehicle to the home and from the home to the vehicle, while also being able to feed the grid.

Other automakers are boosting their energy solutions

Over 630,000 U.S. vehicles already have this functionality, estimates say, and automakers are rapidly expanding their available options with the goal of full vehicle-to-grid support in the long run.

South Korean auto brand Kia and Wallbox, an EV charging company, have teamed up so that drivers of eligible compatible vehicles can have home power backup during outages or during periods of high demand, to cut their utility use. They can send power back to the grid.

Tesla’s technology is similar — allowing drivers of equipped vehicles to connect to their home using additional Tesla hardware. The Cybertruck provides full vehicle-to-home capability, where other Tesla models can only connect to and power specific devices or appliances.

General Motors is also in the energy space.

A recent partnership with WeaveGrid, for instance, allows homeowners who drive certain GM EVs — and have the automaker’s home system and a proper grid interconnection — to enroll in some grid reliability utility programs. Once an outage is detected, GM’s vehicle-to-home tech has the capability to disconnect one's home from the grid and start supplying power from their GM EV.

“If you can imagine the future as we go forward, it's having the ability — now that we have this single platform — that allows our customer to experience our system,” said Wade Sheffer, vice president of GM energy, “but also can have the full control of the energy.”

The capability is an important lifeline amid EV sales slowdown

Not only is this business critical amid growing grid demand and increasing power outages, experts say automakers need to pivot with the EV market less active under current U.S. federal policy. Pure EV sales in the U.S. year-over-year are down 23.8%, according to a July Cox Automotive report on the first half of 2026. This demonstrates what an asset that EV and hybrid ownership can be.

The tech is not without challenges.

On the industry side, these systems have to undergo third-party testing to ensure they meet safety standards, and the vehicle and the charger need to be programmed to communicate. It also requires the approval of the utility where the capability is being used. It could take years to get an interconnect agreement.

On the customer side, homeowners need to understand their vehicles' abilities and how to self-manage their system. It also just brings another generator of power into the home mix.

Still, experts see opportunity, especially with interest in EV sales high outside of the U.S.

“We already know during an outage, its impact, providing electricity to the home,” said Scott Samuelsen, engineering professor emeritus at the University of California, Irvine. “This is going to become very, very popular.”

Rice, UH join major quantum, nuclear energy initiatives

energy impact

Rice University and the University of Houston will be playing a part in the future of energy in Texas and beyond, as Rice has joined the U.S. Department of Energy Quantum Science Center and UH has been added to the Texas Nuclear Alliance.

Rice’s role with the DOE Quantum Science Center will expand the university’s work in helping to develop “fault-tolerant quantum computers capable of solving scientific problems,” according to Rice. Tirthak Patel, an assistant professor of computer science, will develop and evaluate quantum error-correction decoding methods on high-performance computing platforms. Patel’s team will receive $900,000 over 5 years from a DOE-funded center at Oak Ridge National Laboratory.

The Quantum Science Center was established in 2020 under the National Quantum Initiative Act, and brings together national laboratories, universities and industry partners like IBM, AMD, IQM, Quantinuum and Riverlane, and others to advance quantum information science. The Quantum Science Center is one of the DOE’s five National Quantum Information Science Research Centers, and has planned funding of $125 million over 5 years.

“Reliable error correction is one of the biggest challenges in making quantum computing useful for accelerating scientific discovery,” Patel said in a news release. “Our work is focused on developing methods that can scale to future systems and support practical scientific applications.”

Meanwhile, as power demand continues to rise in Texas and North America, the Texas Nuclear Alliance brings industry, academic, and government leaders together to advance nuclear technologies to meet growing energy demands, support economic efforts, bolster domestic manufacturing, and protect overall energy security.

UH brings expertise to the Texas Nuclear Alliance from UH Energy, the Texas Center for Superconductivity at UH (TcSUH), and the Advanced Manufacturing Institute (AMI). UH says that 11 of its 16 colleges will contribute research to the alliance.

“Texas and the University of Houston have long led the nation in energy innovation and research,” Ramanan Krishnamoorti, vice president of energy and innovation, said in a news release. “As demand for reliable, affordable and secure energy continues to grow, advanced nuclear technologies will become increasingly important. The University of Houston is uniquely positioned to contribute through world-class research and deep industry partnerships that help transform breakthrough discoveries into real-world solutions. We look forward to working with the Texas Nuclear Alliance to accelerate technologies that will shape the future of the energy industry.”

Projects from both Rice and UH were selected this week to participate in the DOE's Genesis Mission. Read more here.
