Houston’s SLB has announced plans to acquire German thermal management and heat exchange technology organization Kelvion for approximately $4 billion.

SLB reports in a news release that the acquisition is expected to boost its Data Center Solutions business, as thermal management technologies are key to cooling artificial-intelligence-related infrastructure. Data centers continue to pose numerous challenges, but SLB believes thermal management technology can help ease energy burdens.

“Data centers are becoming more sophisticated and energy-intensive, and customers are increasingly looking for partners that can optimize how critical systems work together across the facility and help bring new capacity online faster,” Gavin Rennick, president of SLB’s New Energy and Industrial business, said in the release. “Thermal management is central to that challenge, and this acquisition allows us to address it directly by delivering more integrated cooling solutions, accelerating innovation, optimizing thermal efficiency, and more directly embedding thermal management into our modular infrastructure offering.”

SLB will acquire Kelvion from funds managed by New York-based financial services group Apollo Global Management Inc. for approximately $3.4 billion in cash and will assume about $700 million of debt, according to the release. The deal is expected to close in Q1 of 2027.

SLB says the acquisition will help it dramatically scale revenue generated by the data center sector.

“This transaction accelerates our ambition to become an industrial technology partner to the data center industry and help customers address the growing infrastructure complexity required to scale AI,” Olivier Le Peuch, CEO of SLB, added in a news release. “Kelvion advances our path toward more integrated data center infrastructure solutions, expands our addressable market — more than doubling our revenue opportunity per gigawatt of delivered capacity — and allows us to scale both our offerings and the global reach of the business.”

SLB reports that it expects its Data Center Solutions business revenues to grow by more than 90 percent annually between 2024 and 2026.

If the acquisition is approved, the combined company will target revenue of $4.5 billion to $5 billion for its data center solutions business in 2028, according to the release.

Kelvion has previously served customers in AI infrastructure, energy system transformation and energy/ industrial markets. Its past work focuses on heat pumps, renewables, carbon capture and processing solutions for thermal management. According to the news release, Kelvion's data center revenue is expected to reach about $1.2 billion in 2026, and the sector is considered the company’s "largest and fastest-growing end market.

New York energy firm scoops up Houston’s Infinity Power Partners

m&a activity

Houston-based energy management and consulting firm Infinity Power Partners has been acquired by New York City-based Environ Energy, which also offers energy management and consulting services.

The deal creates a new “anchor segment” for Environ in the multifamily market. With the addition of Infinity Power’s roughly 2,000 clients in the multifamily sector, representing more than 1 million multifamily units under contract, Environ now has more than 8,000 U.S. clients in the commercial real estate, healthcare, manufacturing, education and government sectors.

“This acquisition continues to solidify our presence in key energy markets while aligning with founders who share our deep commitment to client success,” Environ CEO Chris Sternberg said in a news release.

Infinity Power co-founders and managing partners Nick Altman and Peter Selber have joined Environ, a portfolio company of investment firm 424 Capital. Altman and Selber founded Infinity Power in 2011.

“We built our business one relationship at a time,” Selber said, “with a strong commitment to the communities we serve. That same dedication is reflected in Environ’s approach — now delivered at scale.”

Altman says the acquisition is part of the “next chapter” in energy management. Energy management services help commercial customers reduce utility bills, improve equipment life, achieve green energy goals, and decrease risk tied to fluctuating energy prices.

Energy management is a culture for continual improvement of energy performance and efficiency that’s integrated within an organization’s normal business practice,” according to the U.S. Office of Energy Efficiency & Renewable Energy.

In all, Environ has made six acquisitions in the past 17 months.

Last year, Environ acquired another Houston-based energy management and consulting firm, CSD Energy Advisors. In that deal, Environ gained nearly 1,000 clients, including several Fortune 500 companies and three large industrial energy users in Texas. As part of the deal, CSD co-founders Andrew Barth and JB Sowyrda joined Environ.

Also last year, Environ purchased Carrollton-based energy advisory firm Rapid Power Management (RPM).

“As demands on the energy grid continue to grow, Dresser plays a critical role as a trusted partner to utilities managing essential infrastructure. The company’s products are foundational to the safe and reliable operation of gas and water networks, and its reputation for quality has helped build longstanding customer relationships,” David Foley, global head of Blackstone Energy Transition Partners, and JP Munfa, senior managing director, said in the release.

Blackstone Energy Transition Partners has invested more than $28 billion across the energy transition sector. New York-based Blackstone closed Blackstone Energy Transition Partners Fund IV at $5.6 billion in February 2025. Blackstone Energy Transition Partners Fund III closed in 2020 for $4.4 million, according to Pitchbook.

Other notable energy transition investments from Blackstone funds include Salt Lake City-based Energy Exemplar, French electronics manufacturing company Sediver, Plano-based Westwood Professional Services and others.

Two years ago, Dresser secured a $335 million credit facility from funds managed by asset manager Blue Owl Capital. At the time, Dresser said the money would go toward capital expenses, acquisitions and corporate needs.

This is the second notable investment Blackstone has made in a Houston-based energy company in recent months. In May, Blackstone and energy heavyweight Halliburton made a $1 billion equity investment in Houston power generation startup VoltaGrid, which provides behind-the-meter mobile power generation equipment for data centers, microgrids and industrial customers.

Kanin Energy raises up to $100M for waste-heat-to-power projects

fresh funding

Kanin Energy, a member of the Greentown Labs climatech and energy incubator in Houston, recently raised as much as $100 million in capital to grow its energy-as-a-service platform.

S2G Investments led a round of up to $50 million, and the Canada Growth Fund chipped in an additional $50 million. The money will primarily support Kanin’s development and operation of waste-heat-to-power projects.

Kanin—founded in 2020 in Calgary, Alberta, Canada—builds and runs onsite power assets for large-scale energy users. The startup says its energy-as-a-service offering lowers power costs, boosts power reliability and decreases emissions.

The company operates a waste-heat-to-power project at Ohio’s University of Dayton. The project supplies zero-emission electricity.

Kanin has a pipeline of projects totaling about 50 megawatts of capacity. This includes a waste-heat-to-power plant at the Phillips 66 Mewbourn gas-processing plant near Greeley, Colorado.

“Kanin was built on the belief that industrial facilities already hold the solution to their own energy challenges, they just need the right partner to execute,” Janice Tran, CEO of Kanin, who is based in Houston, said in a release. “At a time when power costs continue to rise, [our] solutions are an important tool for our industrial customers to manage their costs, operations, and emissions.”

Marisa Sweeney, principal at S2G, says waste heat is a largely underused resource for lowering power costs, alleviating grid congestion and improving power reliability.

The waste-heat-to-power process captures thermal energy from industrial activities and converts it to electricity. This happens without using extra fuel or generating more emissions.

Kanin says up to 58 percent of energy consumed by industrial processes is lost as waste heat. This heat winds up in the atmosphere at thousands of facilities in North America, including oil-and-gas operations, cement plants, and steel mills, the startup says.

Kanin was founded in 2020 in Calgary, Alberta, Canada. It opened offices at Greentown Labs Houston in July 2022.

7 Houstonians from energy sector make Forbes list of richest Americans

Rich List

The richest billionaires in America have a collective worth of $8 trillion in 2026, a staggering $1.4 trillion increase since last year, says Forbes. American billionaires are so wealthy that it now takes an unprecedented $4.4 billion net worth to be considered one of the richest people in the country. And one local billionaire has regained the title as Houston's wealthiest resident.

The annual Forbes 400 list is a definitive ranking of the wealthiest Americans, using interviews, financial data, and documentation provided by billionaires and their companies. In all, 43 billionaires across Texas made it on the 2026 list, and 10 are based in Houston. Seven of them have ties to the energy industry.

Oil tycoon Jeffery Hildebrand, 67, now reigns as the No. 1 richest Houstonian, the 9th richest Texan, and the 88th richest person in America for 2026. Hildebrand's net worth has surged $4.7 billion since last year, bringing his current net worth to $14.7 billion. He cofounded Hilcorp, one of the largest privately owned oil and natural gas producers in the U.S., in 1990 and served as its CEO until 2018. He still serves as the chairman of the company.

Kinder Morgan chairman Richard Kinder is the No. 2 richest in Houston. Kinder, 81, was dubbed Houston's richest billionaire in the 2025 Forbes 400 list. His net worth has increased from $11.1 billion to $12.9 billion in just one year. He is the 11th richest Texan and the 100th richest person in America.

Houston pipeline heir Randa Duncan Williams ranks 124th on the list with an estimated net worth of $11.7 billion. Fellow pipeline heirs Dannine Avara and Milane Frantz tie for 128th nationally. Each has an estimated net worth of $11.6 billion. Scott Duncan ties for No. 137 with an $11.3 billion estimated net worth.

Energy exploration chief executive George Bishop of GeoSothern Energy ranks No. 380 with an estimated net worth of $4.5 billion. Last year: $4.7 billion.

Here's how the rest of Houston's billionaires, outside of the energy industry, ranked on this year's list:

  • Toyota mega-dealer Dan Friedkin, 61, is the 102nd richest American with an estimated net worth of $12.9 billion, up from $9.7 billion last year. He most notably owns Gulf States Toyota, which sold $14.5 billion worth of Toyotas in 2025, per Forbes.
  • Hospitality honcho Tilman Fertitta, 69, has a net worth of $12.3 billion and is the 110th richest American. Fertitta owns hospitality corporation Fertitta Entertainment and the NBA team Houston Rockets. He most recently purchased the WNBA's Connecticut Sun and plans to relocate them to Houston under the Houston Comets name in 2027. He also keeps himself busy as President Trump's ambassador to Italy.
