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.

Houston startup wins Space Force contract to advance quantum energy generator

quantum contract

Houston-based quantum energy technology startup Casimir Inc. has been awarded an STTR Phase I contract from the U.S. Space Force's SpaceWERX to support the development of the company's solid-state generator for potential use by the Department of the Air Force.

SpaceWERX is the innovation arm of the U.S. Space Force and a division within AFWERX, the incubator and innovation arm of the United States Department of the Air Force. The Air Force Research Laboratory and SpaceWERX, along with many other government agencies, help support innovation through the Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) grants and contracts.

As part of the new contract, Casimir will work to refine a fully independent generator. Casimir’s solid-state power technology could support national security missions by providing reliable power even in difficult-to-service environments.

In May, Casimir emerged from stealth, netting a $12 million seed round to commercialize its quantum energy chip. The semiconductor chips can generate power from quantum vacuum fields without the need for batteries or charging. The company aims to include the chips in large-scale energy systems that can power homes, commercial infrastructure and electric vehicles.

“This STTR funds some analysis work to address our proposed scaling approach of making our chips multi-layer to increase aggregate power,” Harold “Sonny” White, founder and CEO of Casimir, tells Energy Capital.

White adds that the company will work with Texas A&M to develop chip planarization techniques to support Casimir’s plans to scale. Additionally, White says the company is working with the U.S. Space Force to explore more applications for its technology.

“Casimir’s technology brings a new capability to the market in the form of our persistent power chips,” White adds. “This approach will be relevant to ultra-low-power electronics, and with the scaling approach we are developing, connected with the STTR work, will eventually be relevant to consumer electronics and beyond.”

Casimir has previously reported that it plans to commercialize its first-generation MicroSparc chip by 2028. The chips are expected to power devices for years without the need for replacements.

The total funding for this project has not yet been disclosed.

Sage Geosystems brings South Texas geothermal plant online

powering up

Houston-based Sage Geosystems, a provider of geothermal power, has begun full operations at its South Texas facility for the San Miguel Electric Cooperative.

Sage says the plant was recently “placed in service,” according to a news release. This means it’s fully built and tested, and ready to generate and supply electricity to the grid.

Since selling its first electricity in Q2 of this year, the facility has been operating for more than four months to evaluate aspects like efficiency and water management. Sage relied on its GeoTwin modeling tool to carry out some of the testing.

The testing demonstrates Sage’s proprietary approach to geothermal power “overcomes one of the industry’s most persistent challenges, high water losses in engineered reservoirs, while delivering the consistent performance required to scale next-generation geothermal,” co-founder and CEO Cindy Taff said in the release.

Sage says the South Texas facility will serve as a model for future projects, including one in Nevada. The Nevada facility will use Sage’s proprietary technology to extract geothermal heat from hot dry rock, creating a reliable, affordable source of carbon-free power.

During the testing period, water losses amounted to less than 10 percent. This low rate indicates most water remains in the system, enabling Sage to capture more usable energy, boost power production and improve the project’s finances, the company says.

“Commercial geothermal isn’t just about creating a reservoir. It’s about creating one whose performance can be engineered, predicted, and consistent,” Lev Ring, the company’s co-founder, president and chief technology officer, said in the release.

Since being founded in 2020, Sage has raised $159 million in outside funding. This includes a more than $97 million Series B round co-led by Ormat Technologies and Carbon Direct Capital.

Two years ago, Sage announced a deal with Meta Platforms, the parent company of Facebook and Instagram, to supply up to 150 megawatts of geothermal power to Meta data centers.
