My first CERAWeek was a blur.

Having top energy executives, policymakers, and technologists all gathered in Houston—over 11,000 of them this year—was both overwhelming and energizing. The theme was “Convergence and Competition: Energy, Technology, and Geopolitics,” and walking through the George R. Brown Convention Center, it was immediately clear that this was no ordinary industry conference.

As a first-timer with a Greentown Labs lens, here’s what really stuck with me.

Disruption is the new normal

CERAWeek 2026 was set against the backdrop of conflict in the Middle East, the continued race to power AI, and a clear throughline: disruption is increasingly the new normal. You could feel it in every hallway conversation. The ongoing conflict in the Middle East, specifically Iran’s attacks on Qatar’s Ras Laffan facility and the closure of the Strait of Hormuz, affected roughly 20% of the world’s liquified natural gas supply, and that was woven into nearly every conversation throughout the week.

Secretary of Energy Chris Wright opened the conference with “Energy is life,” then quickly turned to natural gas. “America’s superpower is natural gas,” he said, pointing to its role in industry, heat, electricity, fertilizer, exports, and leading AI and manufacturing. That set the tone early and it never really shifted.

AI is still everywhere, but the conversation has shifted

No surprise that AI dominated the agenda. But what struck me as a first-timer was how much the conversation had matured. The AI discussion has moved from general enthusiasm to a much more practical focus on real use cases and measurable outcomes.

NVIDIA, Anthropic, and CyrusOne joined the established tech presences of Microsoft, Google, and AWS, occupying the Innovation Agora’s new AI Hub, which displaced the hydrogen hub from prior years. That detail alone tells you something about where the energy conversation has shifted. Annual global investment in data centers reached $771 billion in 2025, nearly on par with oil and gas ($835 billion) and renewable energy ($798 billion). We are not talking about a niche technology story anymore. This is a capital story, an infrastructure story, and an energy story all at once.

The prevailing tone was uncertain; the gap between what is being announced and what can actually be delivered was the subtext of almost every conversation. Transmission takes over a decade to build. The new generation takes five to nine years. AI infrastructure moves on three-to-five-year timelines. The math doesn’t work yet, and everyone is aware.

Pitch competitions still draw crowds

The Energy Venture Day and Pitch Competition at the McKinney Balcony was one of my favorite events of the week. Seeing Greentown members on that stage never gets old, but what really energized me was the broader mix: students, new founders, and veteran entrepreneurs in one space, all talking about how what they’re building is going to impact the world. S&P Global launched the NextGen cohort with 100+ graduate students from around the country getting a front-row seat to the energy sector.

Geothermal may have stolen the show

If I had to pick the most surprising theme of my first CERAWeek, it was geothermal. It drew the most consistent endorsement of the week, with Department of Energy representatives, oil and gas majors, and operators broadly aligned on its potential. Project InnerSpace hosted a dedicated Geothermal House for the first time, launching a standardized resource classification framework with the Society of Petroleum Engineers and an XPRIZE collaboration targeting surface-plant supply chain breakthroughs. For a sector that has lived in the shadows of wind and solar for years, CERAWeek 2026 was geothermal’s time to shine.

Wow, was I impressed with Melanie Nakagawa

Melanie Nakagawa, chief sustainability officer at Microsoft, delivered an impressive keynote during her fireside chat with Brad Burke. Her depth of experience, from the U.S. Department of State and venture capital to her current role at Microsoft, was matched only by her calm, hopeful demeanor. Leaders like her at the helm of climate action inspire genuine confidence in the future.

What about hydrogen?

Hydrogen was notably absent from the main stage. The AI Hub in the Innovation Agora displaced the hydrogen hub that had been a fixture in prior years. Seems like hydrogen still plays a role, but not as quickly or broadly as hoped. Blue hydrogen is moving forward cautiously. It wasn’t gone from the conversation entirely, but it no longer commands the room.

The label problem isn’t going away

Politics continues to polarize the industry. Climatetech, sustainability, cleantech — some labels carry broad objectives, others have become tribal signals. “Energy transition” for some means a replacement of fossil fuels; for others, it means an evolution across multiple dimensions simultaneously. CERAWeek 2026 showed an industry increasingly focused not on feel-good narratives about the future of energy, but on the harder questions of security, buildout, reliability, affordability, and competitiveness. A pragmatic shift may be the best answer to the label problem.

Collaboration isn’t optional—it’s strategic

The energy transition is no longer primarily an environmental story. It has become a technology and national competitiveness story. The problems are too big for any one company, sector, or country to solve alone. From incubators and investors to utilities and hyperscalers, the message was consistent all week: move together or we don’t move. S&P Global introduced “The Bridge,” a new venue specifically for energy-tech crossover conversations: a small but meaningful signal that even the conference organizers recognize that collaboration will get us further.

The scale and the energy in the room (pun intended) are what stood out most from my first CERAWeek. The industry knows what needs to get built. The question now is whether we can work together to build it fast enough.

See you next year, CERAWeek.

Alabama-based renewable fuels company to move HQ to Houston

welcome to houston

An Alabama-based clean tech company is moving its headquarters to Houston.

Alléo Energy announced that it will move its headquarters from Bay Minette, Alabama, to Houston's Ion District. The company develops carbon-negative fuels and renewable commodities through its conversion technology that turns wood waste and cellulosic feedstocks into high-energy, high-yield syngas.

The news comes after Alléo announced the appointment of Benjamin Cowart as its new CEO. Cowart will succeed Alléo founder Simeon Chow, who will serve as president.

“Ben doesn’t need to be sold on carbon-negative fuels; he’s already building in this exact space, and he’s thrived through some of the hardest conditions the industry has faced,” Chow said in a news release. “He knows how to scale and he knows the capital markets that finance them; he turns the hurdles that stall other companies into momentum. Bringing a leader of his caliber in as CEO is a defining, energizing moment.”

Cowart previously founded Houston-based renewables Vertex Energy Inc. The company went public on the Nasdaq exchange in 2009 through a reverse merger. He served as chairman and CEO of the company, which was later taken private by a consortium led by BlackRock.

Cowart also founded EVH Corp., a venture platform focused on building in hydrogen, methanol, sustainable aviation fuel (SAF), and low-carbon marine fuels.

“I’ve spent my career turning advanced process technology into high-performing enterprises that deliver both economic and environmental returns in an industry defined by headwinds,” Cowart added in the release. “The winners in energy transition aren’t the ones with the best headline; they’re the ones that keep their economics intact when subsidies move, feedstock prices swing, and capital gets expensive. Alléo is well-built for that. I’ve rarely seen a technology company this well positioned for what the market is demanding. The science is proven; now it’s about disciplined execution, financing, and building more plants. This is the work I love most.”

Alléo plans to scale its proprietary conversion technology. The company commissioned the first phase of its Alabama facility in 2023, which produced renewable diesel made entirely from wood waste, which could be converted to SAF.

The company says that it has $50 million invested in initial research and development, and that additional facilities are in the planning stages.

J.J. Watt takes a run at energy sector with Base Power investment

power play

Since retiring from the NFL three years ago, Houston Texans legend J.J. Watt has been exploring a new field—investing.

In 2023, the former defensive end and current CBS Sports football analyst bought a stake in English soccer team Burnley FC. A year later, he invested in the PopUp Bagels chain.

This summer, Watt made what may be his highest-profile investment yet. He contributed to a $1 billion Series D round for Austin-based energy startup Base Power, which has an office in Houston. It’s Watts’ first investment in the energy sector.

“I like companies that solve real problems, and Base is lowering power bills, protecting families, and building the whole thing themselves right here in Texas,” Watt said in a company news release.

“What impressed me wasn’t just how fast they’ve grown,” he adds. “It’s that they’ve already saved Texans millions on their power bills and kept thousands of homes running when the lights went out. That’s why I invested.”

Base Power is building a distributed network of residential batteries that’s designed to strengthen the grid and lower electrical bills. The startup now powers more than 30,000 homes in Texas, including the Houston area, and recently expanded to Illinois.

Base Power’s $1 billion round lifted its valuation to $13 billion. Since being founded in 2023, the startup has raised more than $2.5 billion.

“JJ is a legend in this state, and he earned that as much for how he shows up off the field as for what he did on it,” says Zach Dell, co-founder and CEO of Base Power. "He spent a full day with us asking every hard question he could think of, and then he switched to Base himself. We’re glad to have him partnering with us.”

Zach Dell is the only son of Austin billionaire Michael Dell, chairman and CEO of Round Rock-based Dell Technologies. Michael Dell grew up in Bellaire.

Leading energy companies power Houston's presence on Fortune Global 500

world class

Nine Houston companies landed on the 2026 Fortune Global 500 list, which ranks the world's largest corporations by revenue for the 2025 fiscal year.

Houston's showing on the list was led by energy companies, with Spring’s ExxonMobil claiming the top local spot. Here’s what Houston-area companies made the list, and where they ranked:

  • No. 15 ExxonMobil
  • No. 36 Chevron
  • No. 61 Phillip 66
  • No. 159 Sysco
  • No. 243 ConocoPhillips
  • No. 292 Enterprise Products Partners
  • No. 343 Plains GP Holdings
  • No. 460 SLB
  • No. 481 Hewlett Packard Enterprise

After 12 years as No.1, Arkansas-based Walmart was replaced this year by Seattle-based Amazon in the top spot for 2026. Amazon achieved this by bringing in $700 billion in revenue in 2025, representing a 12 percent increase from the previous year.

"Across global business, we see again and again that the leaders who are winning are those who embrace change,” Alyson Shontell, Fortune's editor in chief and chief content officer, said in a news release. "Amazon has topped the Fortune Global 500, knocking Walmart off its pedestal. The company has continually reinvented itself across new businesses and bold bets—including a $200 billion capital commitment, largely to building its capacity for AI and cloud computing, in this year alone."

The U.S. has 141 companies on the 2026 Fortune Global 500 list, which is the most of any country. Companies in America generated $15.5 trillion in aggregate revenues, a 6 percent increase from the previous year.

The number of women CEOs at Fortune Global 500 companies reached a record of 34 top leaders, who represented 6.8 percent of CEOs of companies on the list.

Technology was the standout growth industry on this year’s list, with 38 companies earning revenues that grew 20 percent to about $4 trillion in 2025, with profits climbing 36 percent to $835 billion. The financial sector accounted for the largest share of companies on the list again, with 123 companies in that sector. The energy sector claimed the No. 2 industry spot with 77 companies making the list.

In June, the Fortune 500 list was released, and Texas led the United States with 57 Fortune 500 companies headquartered in the state, generating $2.8 trillion in combined revenue.
