As of this month, ExxonMobil's headquarters is officially Houston, according to a recent filing.

ExxonMobil's company page on the United States Securities and Exchange Commission now lists its new Houston-area address — 22777 Springwoods Village Parkway in Spring. While the ExxonMobil's site still lists it's Irving, Texas, address, the SEC filing dated July 5 marks a significant step toward the HQ move that Exxon originally announced in early 2022.

In the initial announcement, the company disclosed that the move, which will combine its chemical and refining divisions, will be completed by 2023. ExxonMobil’s Spring office was opened by former CEO Rex Tillerson in 2014.

With the relocation announcement, ExxonMobil became Houston’s 25th Fortune 500 headquarters, the third highest concentration in the country, after New York and Chicago, per the Greater Houston Partnership. It's slated to be the largest Fortune 500 company to be headquartered in the Houston region, ranking No. 10 in the 2021 listing based on $181.5 billion revenues in 2020.

“ExxonMobil’s move further solidifies Houston’s position as the Energy Capital of the World," the Greater Houston Partnership noted in a January 31 statement. "ExxonMobil is a key participant in our Houston Energy Transition Initiative, and we look forward to working with the company as we continue to position Houston to lead the energy transition to a low-carbon future."

Since the announcement, ExxonMobil has grown its Houston presence by signing on as a founding partner at the Ion, a Midtown Houston 266,000-square-foot building developed and managed by Rice Management Company, last summer. The company joins existing Ion founding partners Aramco, Chevron Technology Ventures, Baker Botts, and Microsoft, as well as affiliate partners bp and Intel. The company joins the Ion "to help develop solutions for the world’s emerging energy issues," per the June 13 news release.

“ExxonMobil has been a leader in energy technology for over a century. Collaboration is essential to both augment our capabilities and accelerate the development of scalable solutions,” said Linda DuCharme, president of ExxonMobil Technology and Engineering Company, in the release. “Our partnership with The Ion will enable us to tap into the extraordinary talent in Houston.”

Houston robotics company partners with Marathon Petroleum to scale fleet

robot alliance

Houston- and Boston-based Square Robot Inc. has announced a partnership with downstream and midstream energy giant Marathon Petroleum Corp. (NYSE: MPC).

The partnership comes with an undisclosed amount of funding from Marathon, which Square Robot says will help "shape the design and development" of its submersible robotics platform and scale its fleet for nationwide tank inspections.

“Marathon’s partnership marks a major milestone in our mission to transform industrial tank inspection,” David Lamont, CEO of Square Robot, said in a news release. “They recognize the proven value of our robotic inspections—eliminating confined space entry, reducing the environmental impact, and delivering major cost efficiencies all while keeping tanks on-line and working. We’re excited to work together with such a great company to expand inspection capabilities and accelerate innovation across the industry.”

The company closed a $13 million series B last year. At the time of closing, Square Robot said it would put the funding toward international expansion in Europe and the Middle East.

Square Robot develops autonomous, submersible robots that are used for storage tank inspections and eliminate the need for humans to enter dangerous and toxic environments. Its newest tank inspection robot, known as the SR-3HT, became commercially available and certified to operate at a broader temperature range than previous models in the company's portfolio this fall.

The company was first founded in the Boston area in 2016 and launched its Houston office in 2019.

Eclipse Energy lands Weatherford investment to scale clean hydrogen tech

clean energy collab

Oil and gas giant Weatherford International (NASDAQ: WFRD) has made a capital investment for an undisclosed amount in Eclipse Energy as part of a collaborative partnership aimed at scaling and commercializing Eclipse's clean fuel technology.

According to a release, joint projects from the two Houston-based companies are expected to launch as soon as January 2026. The partnership aims to leverage Weatherford's global operations with Eclipse Energy's pioneering subsurface biotechnology that converts end-of-life oil fields into low-cost, sustainable hydrogen sources.

“We strongly believe the subsurface is the most overlooked climate asset,” Prabhdeep Singh Sekhon, CEO of Eclipse Energy, said in the release. “This partnership demonstrates how traditional oilfield expertise and frontier biotechnology can come together to transform the energy transition. Weatherford’s global reach and deep technical knowledge will accelerate our ability to scale our low-carbon technology rapidly and cost-effectively.”

Eclipse Energy, previously known as Gold H2, completed its first field trial this summer, demonstrating subsurface bio-stimulated hydrogen production. According to the company, its technology could yield up to 250 billion kilograms of low-carbon hydrogen, and it could also extend "beyond hydrogen, laying the foundation for the next generation of subsurface clean energy fuels."

Last month, Eclipse Energy won in the Energy Transition Business category at the 2025 Houston Innovation Awards. The company closed an $8 million series A this year and has plans to raise another round in 2026.
