What a difference a year makes.

I have been coming to CERAWeek for as long as I can remember and the Agora track within CERAWeek since it originated. Although freshness likely distorts my thinking, I cannot remember a CERAWeek that seemed so different from the previous year's than this one.

This certainly isn’t a comprehensive summary of the conference, but some of my key take forwards from last week's events.

It’s all about power.

It seemed like everyone associated with the power value chain showed up. Developers, turbine manufacturers, utilities, oil and gas, renewables, geothermal, nuclear, storage, hyperscalers, and lots of innovative companies that aim to squeeze more out of the grid we already have. Most of the companies embraced the “all of the above” sentiment and despite moderators (and some key notes) attempt to force technology picks, most didn’t take the bait.

Practical is in.

Real issues – choke points in supply chains and the workforce, permit timing, cost increases in new generation – were openly discussed both on the stage and in the countless meetings and meet ups in partner rooms and in open spaces throughout the Hilton Americas and the GR Brown.

AI was everywhere.

While there was an understanding that not all the power load growth is coming from AI and Data Centers, that segment was getting all the attention. AI went beyond the retail and human enablement to AI for Optimization and AI for Innovation. The symbiosis of Tech and Energy was evident – power is a constraint, and AI is a game changer. S&P (CERAWeek’s organizer) did a great job of weaving this theme across the conference in both the Executive and Agora sessions.

More gas… and less hydrogen.

Whether it was LNG or gas to power or methane emission management, the US’s dominance in gas was front and center. Hydrogen was largely absent from the Executive talks and where it was topical in the Agora sessions, the need for better economics was made clear.

Consistency and balance are needed for this sector.

I am unsure whether it is a “stay calm and carry on” approach, as one leader fashioned, or rather a “carry on” message and imperative. Phrases like “one extreme to another” were heard on stage and in the hallways. The oil and gas CEOs talked more openly about their base business than they had in the last four years but they also talked about their decarbonization activities as well as commercialization of new technologies and value chains.

The macro-economic picture cast long shadows.

While few talks onstage addressed tariffs, consumer sentiment, inflation and unemployment (including those from government officials), the talks in the halls and private meetings certainly did. And while some argued that “the end justifies the means,” it wasn’t an argument that most seemed to buy into.

There is a lot of tripping up on labels.

Politics makes our sector more polarizing than it should or needs to be. Climatetech, Sustainability, Cleantech – some were labels with broad objectives, and some were meant to be binary or exclusionary. "Energy Transition" for some meant a binary replacement of fossil fuels with renewables, and for others, it meant an evolution of a system in multiple dimensions. In any event, a lot of energy is being spent on the labels and the narratives. I don’t have an easy answer for this other than to fall back to longer discussions and less use of labels that have lots of meanings and can quickly move a constructive discussion onto the third rail.

Collaboration is key and vital in this uncertain world.

The attendance of approximately 10,000 spanned the breadth of energy, those who make, move, and use it from around the globe—in other words, everyone—with a strong tone of inclusion. CERAWeek, after all, is all about convening and collaboration, and this played out in the programming and the networking. The messages about practicality, consistency, balance and “all of the above” and the storm clouds of the extremes seemed to put everyone in a similar boat: Am I being too hopeful that this will lead to more and more collaboration within the sector to advance the multiple aims of affordability, reliability, security, resiliency and sustainability?

The next-generation workforce is a strategic imperative.

The NextGen cohort in Agora was launched with 100+ graduate students from all over coming to see the energy sector close up. Kudos to S&P for making this investment and to all the conference attendees who spent time talking to the students about their research, their interests, and, importantly, sharing their career stories. Relationships were born at CERAWeek.

Houston showed well for the conference and Mother Nature played nice. The days were sunny and dry, and the evening temperatures fit the outdoor events well. The schedule and pace of CERAWeek is exhausting, and most people were worn out by Thursday.

CERAWeek 2025 is in the books; the connections made, and messages heard set the tone for the year ahead.

Until CERAWeek 2026.

3 Houston climate tech companies win challenge for sustainable aviation

winner, winne

Greentown Houston companies have made the list of companies working toward sustainable aviation technology.

Cemvita and Verne, two Greentown Houston members, and C2V Initiative Year 1 participant Air Company were all named as winners of the World Economic Forum’s Sustainable Aviation Challenge, which will net the winners visibility opportunities, curated introductions to industry partners and potential funders, and other event invitations.

“We look forward to start collaborating with fellow winners and challenge partners to support the decarbonization of the aviation sector,” Cemvita writes in a statement on LinkedIn.

The Sustainable Aviation Challenge on UpLink included innovators who accelerate the adoption and development of sustainable aviation fuel and other propulsion solutions. Aviation accounts for 2 percent of global greenhouse gas emissions and air travel is projected to increase over this decade according to the International Energy Agency. The challenge is to reinvent flying and make it compatible with our global net-zero emissions targets. Decarbonizing aviation is one of the goals to help with the goal of global net-zero emissions.

Cemvita’s eCO2™ helped garner the Houston company its spot in the Sustainable Aviation Challenge. The eCO2 takes waste streams and carbon dioxide and uses them to produce valuable materials like plastics,proteins, and fuel feedstock through microbiology. Cemvita also plans to remove 250 million tons per year from the atmosphere by 2050, according to their website.

Last fall, Cemvita Corp. announced a new offtake arrangement with United Airlines. Cemvita's first full-scale sustainable aviation fuel plant will provide up to 1 billion gallons of SAF to United Airlines. The 20-year contract specifies that Cemvita will supply up to 50 million gallons annually to United.

Hobby debuts solar canopy as airport system reaches new sustainability milestone

solar solutions

Houston's William P. Hobby Airport is generating its own clean energy.

Houston Aiports announced that Hobby's red garage is now home to a "solar canopy" that is producing energy at 100 percent capacity to power daily operations. The photovoltaic (PV) solar system generated more than 1.1 gigawatt-hours of electricity in testing, and is expected to produce up to 1 megawatt-hour now that it's operating at full power.

“This project is proof that sustainability can be practical, visible and directly tied to the passenger experience,” Jim Szczesniak, director of aviation for Houston Airports, said in a news release. “Passengers now park under a structure that shields their cars from the Texas sun while generating clean energy that keeps airport operations running efficiently, lowering overall peak demand electrical costs during the day and our carbon footprint. It’s a win for travelers, the city and the planet.”

The project was completed by Texas A&M Engineering Experiment Station (TEES) and CenterPoint Energy. It's part of Houston Airport's efforts to reduce carbon emissions by 40 percent over its 2019 baseline.

In a separate announcement, the airport system also shared that it recently reached Level 3 in the Airports Council International (ACI) Airport Carbon Accreditation program after reducing emissions by 19 percent in three years. This includes reductions at George Bush Intercontinental Airport (IAH), Hobby and Ellington Airport/Houston Spaceport.

The reductions have come from initiatives such as adding electric vehicles to airport fleets, upgrading airfield lighting with LED bulbs, adding smarter power systems to terminals, and improving IAH's central utility plant with more efficient equipment. Additionally, the expansion to Hobby's West Concourse and renovations at IAH Terminal B incorporate cleaner equipment and technology.

According to Houston Airports, from 2019 to 2023:

  • IAH reduced emissions by 17 percent
  • Hobby reduced emissions by 32 percent
  • Ellington Airport reduced emissions by 4 percent

"I see firsthand how vital it is to link infrastructure with sustainability,” Houston City Council Member Twila Carter, chair of the council’s Resilience Committee, said in the release. “Reducing carbon emissions at our airports isn’t just about cleaner travel — it’s about smarter planning, safer communities and building a Houston that can thrive for generations to come.”

Houston Methodist leader on the push for sustainable health care and new local event

Q&A

Every industry can play a role in the energy transition, and Houston Methodist is leading the charge in the health care sector.

Culminating at this week’s inaugural Green ICU Conference, part of Houston Energy and Climate Startup Week, the health care system has spent the last three years taking a closer look at its environmental footprint—and showing other hospital systems and medical organizations how they too can make simple changes to reduce emissions.

The event, held tomorrow, Sept. 17, at TMC Helix Park, will bring together health care professionals, industry leaders, policymakers and innovators to explore solutions for building a more sustainable healthcare system.

In an interview with EnergyCapital, Dr. Faisal N. Masud, medical director of critical care at Houston Methodist and a champion for sustainability efforts across the system, shares the inspiration behind the event and what attendees can expect to take away.

Tell us about how the Green ICU Conference came to be.

Houston Methodist’s inaugural Green ICU conference is about three years in the making. It originated because Houston Methodist recognized the significant impact health care has on sustainability and the lack of similar initiatives in the U.S.

The Center for Critical Care at Houston Methodist launched a sustainability-focused ICU initiative, published a roadmap and became involved in international efforts to develop guidelines that many other organizations now use. Our work led to the creation of the first Green ICU Collaborative in the country, and the Green ICU Conference was established to share best practices and address the global impact of critical care on the environment.

What were some of the biggest takeaways from the collaborative, and how are they represented in this new event?

Through the Green ICU Collaborative, we’ve seen that health care professionals can make a significant impact on sustainability through simple, practical changes, and many solutions can be implemented without major costs or compromising patient care. Additionally, there’s a strong link between environmental stewardship and patient safety and quality. These lessons will be represented in the new Green ICU Conference by showcasing easy-to-adopt best practices, emphasizing the importance of sustainability in daily health care operations, and fostering a sense of shared responsibility among attendees to improve both patient outcomes and environmental impact.

Why are ICUs considered to be such carbon hot spots?

ICUs are considered carbon hot spots because they care for the sickest patients, requiring intensive therapies, numerous medications and a large amount of equipment, such as ventilators and pumps. This makes them the most resource- and energy-intensive areas in a hospital. A single day in the ICU can have a greenhouse gas impact equivalent to driving a car 1,000 kilometers.

The U.S. health care sector is responsible for approximately 8.5 percent of greenhouse gas emissions, and hospitals are the second-most energy-intensive commercial buildings in the country. With the Texas Medical Center being in the heart of Houston, it’s critical that health care organizations play a role in this area.

That’s why the Center for Critical Care launched a system-wide Green ICU Initiative with the Houston Methodist Office of Sustainability to help reduce our carbon impact and waste while continuing to provide unparalleled patient care. Innovation is part of our culture, and that extends into our sustainability efforts. Houston Methodist’s Green ICU initiative is the first-of-its-kind in the U.S.

What efforts has Houston Methodist taken to cut emissions?

The first step to cutting emissions is measuring an organization’s carbon footprint to determine the best path forward. Houston Methodist’s Office of Sustainability has aggregated two years of baseline emissions data pending third-party validation. The hospital has taken several steps to cut emissions, including implementing composting programs, installing solar panels, improving energy utilization and participating in global plastic recycling initiatives. These efforts are part of a broader commitment led by our Office of Sustainability to reduce the hospital’s environmental footprint.

Tell us a little more about the event. Who should attend? What do you expect to be some of the highlights?

The Green ICU Conference, taking place during Houston Energy and Climate Week, is focused on health care sustainability, bringing together health care professionals, engineers, experts and anyone interested in reducing health care’s environmental impact. With participants and speakers from six countries, the conference brings together leading experts who aim to raise awareness, share best practices and offer practical, easy-to-adopt solutions for making health care more sustainable.

Highlights include perspectives from leading voices in health care sustainability, real-world examples of successful sustainability initiatives and opportunities for networking and collaboration. Anyone interested in health care, sustainability,or making a positive impact in their community should consider attending.

And, because of increasing interest, we’ve opened up the opportunity for attendees to join virtually at no cost or in person.

What do you hope attendees take away? What are your major goals for the event?

The main goals of hosting the Green ICU Conference for the first time are to raise awareness about the environmental impact of health care; engage and empower attendees to implement easy, practical sustainability solutions; and foster a sense of shared community and responsibility.

I hope attendees leave the event feeling motivated and equipped to make meaningful changes in their own practices, whether that’s improving patient care, supporting their colleagues, or leaving their organization and environment in a better place for future generations.

Texas House Democrats urge Trump administration to restore $250M solar grant

solar grants

Eight Democratic members of the U.S. House from Texas, including two from Houston, are calling on the Trump administration to restore a nearly $250 million solar energy grant for Texas that’s being slashed by the U.S. Environmental Protection Agency (EPA).

In a letter to Lee Zeldin, head of the EPA, and Russell Vought, director of the federal Office of Management and Budget (OMB), the House members urged the two officials to reinstate the nearly $250 million grant, which was awarded to Texas under the $7 billion Biden-era Solar for All program. The Texas grant was designed to assist 28,000 low-income households in installing solar panels, aiming to reduce their energy bills.

“This administration has improperly withheld billions in congressionally appropriated funding that was intended to benefit everyday Americans,” the letter stated.

The letter claimed that numerous court rulings have determined the EPA cannot repeal already allocated funding.

“Congress made a commitment to families, small businesses, and communities across this country to lower their utility bills and reduce harmful pollution through investments in clean energy. The Solar for All program was part of that commitment, and the EPA’s actions to rescind this funding effectively undermine that congressional intent,” the House members wrote.

The six House members who signed the letter are:

  • U.S. Rep. Sylvia Garcia of Houston
  • U.S. Rep. Al Green of Houston
  • U.S. Rep. Greg Casar of Austin
  • U.S. Rep. Jasmine Crockett of Dallas
  • U.S. Rep. Lloyd Doggett of Austin
  • U.S. Rep. Julie Johnson of Dallas
  • U.S. Rep. Marc Veasey of Fort Worth

The nearly $250 million grant was awarded last year to the Harris County-led Texas Solar for All Coalition.

In a post on the X social media platform, Zeldin said the recently passed “One Big Beautiful Bill” killed the Greenhouse Gas Reduction Fund, which would have financed the $7 billion Solar for All program.

“The bottom line is this: EPA no longer has the statutory authority to administer the program or the appropriated funds to keep this boondoggle alive,” Zeldin said.
