Two leading companies in Houston's clean energy scene have been named the Texas Exchange for Energy & Climate Entrepreneurship's first experts in residence.

TEX-E announced this month that Houston-based geothermal unicorn Fervo Energy and venture capital firm Mercury Fund have joined the nonprofit's new Expert-in-Residence partnership. The program aims to connect TEX-E Fellows with "the people and organizations shaping the future of energy and entrepreneurship."

The 2026 TEX-E Fellows were named in June and include 67 students from six Texas universities and the Massachusetts Institute of Technology. Nineteen are from Houston universities. See the full list here.

Through the Expert-in-Residence program, fellows will be able to network and work with:

"More than anything, students need the determination and creativity to step outside of their comfort zones and tackle problems that lack clear answers. At Fervo, we've consistently bet on young people who lack traditional 'hard skills' but are willing to embrace uncertainty and learn on the job. That open-mindedness will take students far," Jewett said in a prepared statement. Fervo named Jewett as COO in June.

TEX-E was founded in 2022 through partnerships with MIT Martin Trust Center for Entrepreneurship and Greentown Labs. It works with university students from six schools: Rice University, University of Houston, Prairie View A&M University, The University of Texas at Austin, Texas A&M University and MIT.

The organization named Houston venture capital and innovation leader Sandy Guitar as its new executive director last year. Guitar previously served as general partner and managing director at Houston-based VC firm HX Venture Fund and is co-founder of Weathergage Capital.

TEX-E is known for its student track within the Energy Venture Day and Pitch Competition at CERAWeek. It awarded $50,000 to student teams from the University of Texas and Rice University. Read more here.

SLB to make $4B acquisition to expand data center cooling business

cool deal

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.

Houston geothermal startup bumps Series B to $180M with Nabors investment

fresh funding

Houston-based geothermal startup Quaise Energy has closed its Series B fundraising round at $180 million after inking a significant investment from another local energy leader.

Quaise, which is developing a 50-megawatt superhot geothermal plant in Oregon, announced a "first close" of the round last month at $134 million, led by San Francisco-based investment firm Prelude Ventures. The $46 million bump has been fueled by a $35 million investment from Houston-based Nabors Industries.

The funding will go toward the continued development of the company's superhot geothermal plant, Project Obsidian, as well as the commercialization of Quaise's millimeter-wave drilling system, according to a news release.

“We are unlocking the most powerful clean energy source on Earth, and the Series B signals deep conviction across a wide range of investors,” Carlos Araque, Quaise CEO and president, said in the release. “Nabors is an invaluable partner as we move millimeter wave drilling to full commercial operations at Project Obsidian and beyond.”

Nabors, a repeat investor in Quaise, has also entered into a strategic framework agreement with Quaise. Under the agreement, Quaise will have access to a dedicated Nabors land rig and drilling platform. Nabors will also provide expertise in reservoir modeling, well design and drilling strategy.

Last year, Quaise drilled to a depth of about 330 feet using its millimeter-wave technology at its field site in Central Texas. Canary Media previously reported that Quaise plans to drill to nearly 3,300 feet later this year and to deploy its millimeter-wave technology at its power plant in 2027. The plant is expected to deliver power to the Pacific Northwest in 2030.

Quaise and Nabors say the partnership will improve drilling performance, reduce costs and accelerate project timelines.

“Superhot geothermal has the potential to make clean energy ubiquitous. That is why we are excited about our close relationship with Quaise,” Anthony Petrello, president and CEO of Nabors, added in the release. “Quaise’s millimeter wave technology changes the equation entirely by reaching superhot rock at temperatures and depths that are inaccessible with conventional drilling, transforming geothermal from a location-dependent resource into a global energy solution. Combined with Nabors’ drilling expertise and infrastructure, we see a path to gigawatt-scale geothermal power that no other company can offer today.”

Quaise reports that with the latest funding, it has now raised $280 million. It raised $21 million in a Series A1 financing round in 2024 and a $52 million Series A in 2022.

The company announced in March that it was aiming to raise $200 million for Project Obsidian through $100 million in Series B funding, plus an additional $100 million from grants, debt and project-level finance.
