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.

Houston-based energy companies hailed best places to work by U.S. News

Top cos.

More than a dozen Houston-based companies are sharing the spotlight in U.S. News and World Report's collection of the "Best Companies to Work For" in 2024-2025, including several of the Bayou City’s energy companies.

The annual report examines publicly-traded companies around the world to determine the best employers based on six metrics including work-life balance and flexibility; quality of pay and benefits; job and company stability; career opportunities and professional development; and more. The companies were not ranked, but included based on reader surveys and publicly available data about each workplace.

New for the 2024-2025 report, U.S. News analyzed 549 companies across 29 different lists, including the overall best companies list — which includes the best 300 companies across the U.S., the United Kingdom, Ireland, Switzerland, Luxembourg, and Bermuda — 24 industry-specific lists, and four regional lists.

There were 16 total companies based around Houston that made the lists, with the majority being based in the city, while one each were located in Spring and The Woodlands.

Independent energy company Marathon Oil was the top-rated Houston energy employer, with nearly 1,700 employees, an annual revenue stream of $6.38 billion, and a $15.4 billion market cap. The company was specifically highlighted with a "Top Quality of Pay" label, but also boasts high ratings for its employees' work-life balance, job stability, and belongingness.

In addition to being included in the overall "Best Companies" list, Marathon Oil earned recognition in the industry-specific "Best in Energy" list and the "Best Companies in the South" list.

A second Houston-based energy company earning a spot among the top employers is Occidental (also known as Oxy). The petroleum corporation, which has been in operation since 1920, has nearly 12,600 employees and brings in $27,43 billion in revenue every year.

According to U.S. News, Occidental offers many financial, health and wellness, and workplace benefits including 401k matching, tuition assistance, an employee assistance program, flexible work arrangements, and much more. The company was also given a "Top Quality of Pay" designation.

Occidental appeared in U.S. News' "Best in Mining and Raw Materials," the overall "Best Companies," and "Best Companies in the South" lists.

The other top energy employers include:

  • Southwestern Energy Company, Spring – Best in Energy; Best Companies (overall); Best Companies in the South
  • ConocoPhillips – Best in Energy, Best Companies in the South
  • Cheniere – Best in Energy
  • EOG Resources – Best in Energy
  • Murphy Oil Corporation – Best in Energy

"Prospective and current employees understand the significant impact their employer has on their quality of life," said Carly Chase, vice president of careers at U.S. News and World Report, in a release. "Whether a new grad seeking a company to launch their career, an established professional looking for a change or an HR professional researching the strengths of their company and others, Best Companies to Work For provides a central space to see which companies are meeting their employees' needs best.

ConocoPhillips buying Marathon Oil for $17.B in all-stock deal as energy prices rise

M&A moves

ConocoPhillips is buying Marathon Oil in an all-stock deal valued at approximately $17.1 billion as energy prices rise and big oil companies reap massive profits.

The deal to combine the two Houston-headquartered companies is valued at $22.5 billion when including $5.4 billion in debt.

Crude prices have jumped more than 12% this year and the cost for a barrel rose above $80 this week. Oil majors put up record profits after Russia's invasion of Ukraine in 2022 and while those numbers have slipped, there has been a surge in mergers between energy companies flush with cash.

Chevron said last year that it was buying Hess in a $53 billion acquisition, though that deal faces headwinds. The company warned the buyout may be in jeopardy because it will require the approval of Exxon Mobil and a Chinese national oil company, which both hold rights to development of an oil field off the coast of the South American nation Guyana where Hess is a big player.

In July of last year, Exxon Mobil said that it would pay $4.9 billion for Denbury Resources, an oil and gas producer that has entered the business of capturing and storing carbon and stands to benefit from changes in U.S. climate policy. Three months later, Exxon announced the proposed acquisition of shale operator Pioneer Natural Resources for $60 billion.

All of the proposed acquisitions could face pushback from the U.S. which, under the Biden administration, has stepped up antitrust reviews for energy companies and other sectors as well, such as tech.

Federal Trade Commission, which enforces federal antitrust law, asked for additional information from Exxon and Pioneer about their proposed deal. The request is a step the agency takes when reviewing whether a merger could be anticompetitive under U.S. law. Pioneer disclosed the request in a filing in January.

As part of the ConocoPhillips transaction, Marathon Oil shareholders will receive 0.2550 shares of ConocoPhillips common stock for each share of Marathon Oil common stock that they own, the companies said Wednesday.

ConocoPhillips said Wednesday that the transaction will add highly desired acreage to its existing U.S. onshore portfolio.

“This acquisition of Marathon Oil further deepens our portfolio and fits within our financial framework, adding high-quality, low cost of supply inventory adjacent to our leading U.S. unconventional position,” ConocoPhillips Chairman and CEO Ryan Lance said in a prepared statement.

The deal is expected to close in the fourth quarter. It still needs approval from Marathon Oil stockholders.

Separate from the transaction, ConocoPhillips said that it anticipates raising its ordinary dividend by 34% to 78 cents per share starting in the fourth quarter. The company said that once the Marathon Oil deal closes and assuming recent commodity prices, ConocoPhillips plans to buy back more than $7 billion in shares in the first full year. It plans to repurchase more than $20 billion in shares in the first three years.

Shares of ConocoPhillips declined 3.3% before the market open, while Marathon Oil Corp.'s stock rose more than 7%.

Houston-based ENGIE to add new wind and solar projects to Texas grid

coming soon

Houston-based ENGIE North America Inc. has expanded its partnership with Los Angeles-based Ares Infrastructure Opportunities to add 730 megawatts of renewable energy projects to the ERCOT grid.

The new projects will include one wind and two solar projects in Texas.

“The continued growth of our relationship with Ares reflects the strength of ENGIE’s portfolio of assets and our track record of delivering, operating and financing growth in the U.S. despite challenging circumstances,” Dave Carroll, CEO and Chief Renewables Officer of ENGIE North America, said in a news release. “The addition of another 730 MW of generation to our existing relationship reflects the commitment both ENGIE and Ares have to meeting growing demand for power in the U.S. and our willingness to invest in meeting those needs.”

ENGIE has more than 11 gigawatts of renewable energy projects in operation or under construction in the U.S. and Canada, and 52.7 gigawatts worldwide. The company is targeting 95 gigawatts by 2030.

ENGIE launched three new community solar farms in Illinois since December, including the 2.5-megawatt Harmony community solar farm in Lena and the Knox 2A and Knox 2B projects in Galesburg.

The company's 600-megawatt Swenson Ranch Solar project near Abilene, Texas, is expected to go online in 2027 and will provide power for Meta, the parent company of social media platform Facebook. Late last year, ENGIE also signed a nine-year renewable energy supply agreement with AstraZeneca to support the pharmaceutical company’s manufacturing operations from its 114-megawatt Tyson Nick Solar Project in Lamar County, Texas.

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.
