Katy-based TerraFlow Energy, an energy storage and infrastructure company, has acquired Houston-based battery technology startup FlowCellutions. Financial terms weren’t disclosed.

FlowCellutions still operates under its established name, but with the tagline “A TerraFlow Energy Company.” Becca Segel, founder and CEO of FlowCellutions, now runs the business as its president.

FlowCellutions specializes in electrochemical sensing, diagnostics, analytics, and testing that offer insights into battery chemistry, charging capabilities, and system performance.

“FlowCellutions has always been focused on developing better ways to understand what is happening inside a flow battery and using that information to improve how these systems perform,” Segal said in a press release. “Joining TerraFlow gives us the opportunity to apply that work at a much larger scale while continuing to build the capabilities and expertise that make FlowCellutions unique.”

The FlowCellutions platform supports data centers and other heavy users of power. It’s designed to help reduce operating costs, prevent failures and costly downtime, and extend battery lifetime from about seven years to more than 30 years.

Segel founded the company in 2022. A member of Greentown Labs, the company raised more than $2 million in non-dilutive funding and received $1.5 million in National Science Foundation funding earlier this year.

FlowCellutions is one of five finalists in the Energy Transition Business category of InnovationMap’s 2026 Houston Innovation Awards.

“FlowCellutions brings a depth of scientific and technical expertise that fits naturally with where TerraFlow is going,” Jon Parrella, CEO of TerraFlow, said in the release.

“As we move from developing these systems to deploying them at commercial scale, understanding performance at a deeper level matters,” he said. “Bringing FlowCellutions into TerraFlow strengthens that capability and gives both teams more opportunity to advance the technology.”

TerraFlow, founded in 2024, develops long-duration energy storage and power infrastructure for data centers, industrial facilities, utilities and other large power consumers.

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).

New study shows Houston is still feeling effects of 2014-16 oil crash

lasting impact

A new study from Rice’s Kinder Institute shows that Houston is still feeling the economic effects of the 2014-2016 oil crash, more than a decade later.

Though Houston, nicknamed the Energy Capital of the World, has continued to grow over the time period, the city has still fallen behind other comparable metropolitan areas in earnings and job creation, according to the research. The report is one part of a three-part series that will take a look at regional economic mobility and suggest ideas to expand opportunity.

“When you look at what’s happened in other locations, we’re losing ground,” Flávio Cunha, director of the Center for Economic Mobility at Rice’s Kinder Institute for Urban Research, said in a release. “Our economy is growing, but it’s no longer growing at the rate it used to.”

Global oil prices fell 70 percent between 2014 and 2016, the report said, marking one of the three largest declines since World War II and the longest-lasting downturn since 1986. The report excluded pandemic-related gaps, and it mentions 2017’s Hurricane Harvey as a possible indicator that economic growth stalled after the 2014-2016 oil price crash recovery.

To understand the long-term impact of the crash, researchers compared Houston’s economic performance with 54 metropolitan areas like San Antonio, Pittsburgh and others with less dependence on the energy industry.

Some of the key findings in the report included:

  • Job creation: In 2019, Houston had approximately 240,000 fewer private-sector jobs than similar cities. Employment was 15 percent lower in goods-producing industries and 4 percent lower in the services industries than the control group.
  • Income shifts: Income per resident was 13 percent lower compared to the peer group. Workers who remained employed earned 10 percent less between 2015 and 2019 than in other metros. The 13 percent drop in income equates to roughly $76 billion a year in forgone income, or $10,700 per resident per year in 2025 dollars. The decline was a trend across every age group, education level and sex.
  • Population changes: The rate of people moving to Houston slowed, rather than a surge of people leaving.
  • Hiring changes: Hiring fell sharply for young workers ages 19-24.

Cunha says the most surprising finding was that these trends persisted a decade later. According to the report, by 2024, Houston’s wages and income per resident remained about a fifth and a sixth below those in peer cities, and jobs per resident had continued to lose ground.

“What really surprises me is not that there was this change. It’s that this change has been long-lasting,” he added. “We followed it up to 2024, and we still don’t detect that the economy has recovered from that one shock.”

2 fast-growing energy cos. are finalists for Houston Scaleup of the Year

Meet the finalists

From IPOs to groundbreakings, some of Houston's most innovative companies reached major milestones this year.

As part of InnovationMap's 2026 Houston Innovation Awards, the Scaleup of the Year category honors innovative later-stage startups that have recently reached a significant milestone in company growth. Three scaleups have been named finalists for the 2026 award, two of which are in the energy transition sector.

Read more about these businesses, their founders and their breakthrough technologies below. The 2026 winners will be announced on InnovationMap.com in mid-November.

Erock

Energy infrastructure company Erock, previously known as Enchanted Rock, develops dual-purpose microgrids that rely on natural gas and renewable natural gas to produce lower carbon emissions and air pollutants than diesel generators. Its products can provide bridge power before grid interconnection, backup power during outages and dispatchable capacity that supports long-term grid reliability. The company has more than 1,100 megawatts of installed capacity and over 20 years of experience serving commercial, municipal and large-scale technology customers.

Erock completed its initial public offering this year, raising approximately $600 million in gross proceeds. It also grew its contracted power system sales backlog to approximately $1.7 billion, up tenfold year-over-year, with production sold out through 2028, according to the company's application. The company secured a major equipment order from Anthropic, began construction of the 366-megawatt El Paso Electric project supporting Meta's data center campus, and started assembly operations at its Hyperion facility in Cypress, Texas.

Hertha Metals

Hertha Metals produces lower-cost, lower-emission steel and high-purity iron. The company has developed a single-step process that uses natural gas as a direct reductant instead of metallurgical coal, which cuts production costs by more than 25 percent and emissions by up to 50 percent, according to the company. The same process produces high-purity iron needed for high-purity steels and rare earth magnets. The company says it aims to "re-industrialize America’s production of critical materials."

Hertha Metals was founded by CEO Laureen Meroueh in 2022 and emerged from stealth last year with more than $17 million in venture capital funding. The company closed a $133.65 million Series A last month and also broke ground on its $100M high-purity iron factory known as Chalyx in Conroe.

Venus Aerospace

Spacetech company Venus Aerospace is developing a high-thrust rotating detonation rocket engine (RDRE) that replaces the subsonic combustion used in conventional rocket engines. The RDRE is a compact, simpler engine that can deliver up to 15 percent greater efficiency for defense and space applications. It completed its first U.S. flight test of the engine last summer.

Venus Aerospace was founded in 2020 by CEO Cassie Duggleby and CTO Andrew Duggleby. It raised a $20 million Series A in 2022 and $42 million Series A2 in 2025. It closed a $91 million Series B earlier this year and expanded its leadership team. The company is working toward longer-duration and higher-thrust testing and advancing its flight program.

Oxy inks long-term agreements for 2M tons of CO2 capture, transport

carbon contracts

Houston-based Occidental has made two long-term agreements that will expand its carbon management business in the Delaware Basin and the Permian Basin.

Oxy announced Nov. 9 that it has signed agreements with two unnamed project developers to capture and transport approximately 2 million metric tons of CO2 from their existing and new natural gas processing facilities in the Delaware Basin in West Texas annually. The CO2 will be transported for use in Oxy's enhanced oil recovery (EOR) operations in the Permian Basin.

“Securing reliable, long-term sources of CO2 supports Occidental’s advanced recovery strategy to extend the productive life of existing fields and enhance recovery across our conventional and unconventional resource base,” Vishal Gupta, president and general manager of EOR Ventures at Occidental, said in a news release. “The projects, once operational, will help diversify our CO2 supply, improve access to cost-effective resources and create infrastructure that can connect additional carbon capture projects over time. Federal 45Q incentives are an important support for these investments.”

According to the release, the projects have the potential to expand to handle up to 4 million metric tons of C02 per year combined. The first shipments to Oxy are expected in 2029. The unnamed developers will fund and build the infrastructure to capture, transport and deliver the CO2 to Oxy, the company shared in the release.

Additionally, the agreement stipulates that the projects will also include the build-out of nearly 100 miles of new CO2 pipeline infrastructure. The new pipeline is planned to connect with the existing CO2 pipeline network in the Permian Basin. Oxy adds that the pipelines are being designed to handle additional future capacity to "support future conventional and unconventional recovery opportunities" of CO2.

Oxy uses the EOR process to inject stored CO2 back into a producing oil fields to boost the site's performance. The recycled CO2 displaces trapped oil and gas and is then secured in the reservoir. Oxy says that EOR combined with Direct Air Capture (DAC) technology "remove[s] an amount of CO2 equivalent to that emitted during the production and consumption of [its] products."

Oxy subsidiary 1PointFive is developing a $1.3 billion DAC project in the Midland-Odessa area that is slated to be the largest facility of its kind in the world. Known as STRATOS, it's designed to capture up to 500,000 metric tons of CO2 per year. After a component delay, 1PointFive shared in May that it would ramp up operations at the project throughout 2026.
