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.

Rice University spinout lands $500K NSF grant to boost chip sustainability

cooler computing

HEXAspec, a spinout from Rice University's Liu Idea Lab for Innovation and Entrepreneurship, was recently awarded a $500,000 National Science Foundation Partnership for Innovation grant.

The team says it will use the funding to continue enhancing semiconductor chips’ thermal conductivity to boost computing power. According to a release from Rice, HEXAspec has developed breakthrough inorganic fillers that allow graphic processing units (GPUs) to use less water and electricity and generate less heat.

The technology has major implications for the future of computing with AI sustainably.

“With the huge scale of investment in new computing infrastructure, the problem of managing the heat produced by these GPUs and semiconductors has grown exponentially. We’re excited to use this award to further our material to meet the needs of existing and emerging industry partners and unlock a new era of computing,” HEXAspec co-founder Tianshu Zhai said in the release.

HEXAspec was founded by Zhai and Chen-Yang Lin, who both participated in the Rice Innovation Fellows program. A third co-founder, Jing Zhang, also worked as a postdoctoral researcher and a research scientist at Rice, according to HEXAspec's website.

The HEXASpec team won the Liu Idea Lab for Innovation and Entrepreneurship's H. Albert Napier Rice Launch Challenge in 2024. More recently, it also won this year's Energy Venture Day and Pitch Competition during CERAWeek in the TEX-E student track, taking home $25,000.

"The grant from the NSF is a game-changer, accelerating the path to market for this transformative technology," Kyle Judah, executive director of Lilie, added in the release.

Rice research team's study keeps CO2-to-fuel devices running 50 times longer

new findings

In a new study published in the journal Science, a team of Rice University researchers shared findings on how acid bubbles can improve the stability of electrochemical devices that convert carbon dioxide into useful fuels and chemicals.

The team led by Rice associate professor Hoatian Wang addressed an issue in the performance and stability of CO2 reduction systems. The gas flow channels in the systems often clog due to salt buildup, reducing efficiency and causing the devices to fail prematurely after about 80 hours of operation.

“Salt precipitation blocks CO2 transport and floods the gas diffusion electrode, which leads to performance failure,” Wang said in a news release. “This typically happens within a few hundred hours, which is far from commercial viability.”

By using an acid-humidified CO2 technique, the team was able to extend the operational life of a CO2 reduction system more than 50-fold, demonstrating more than 4,500 hours of stable operation in a scaled-up reactor.

The Rice team made a simple swap with a significant impact. Instead of using water to humidify the CO2 gas input into the reactor, the team bubbled the gas through an acid solution such as hydrochloric, formic or acetic acid. This process made more soluble salt formations that did not crystallize or block the channels.

The process has major implications for an emerging green technology known as electrochemical CO2 reduction, or CO2RR, that transforms climate-warming CO2 into products like carbon monoxide, ethylene, or alcohols. The products can be further refined into fuels or feedstocks.

“Using the traditional method of water-humidified CO2 could lead to salt formation in the cathode gas flow channels,” Shaoyun Hao, postdoctoral research associate in chemical and biomolecular engineering at Rice and co-first author, explained in the news release. “We hypothesized — and confirmed — that acid vapor could dissolve the salt and convert the low solubility KHCO3 into salt with higher solubility, thus shifting the solubility balance just enough to avoid clogging without affecting catalyst performance.”

The Rice team believes the work can lead to more scalable CO2 electrolyzers, which is vital if the technology is to be deployed at industrial scales as part of carbon capture and utilization strategies. Since the approach itself is relatively simple, it could lead to a more cost-effective and efficient solution. It also worked well with multiple catalyst types, including zinc oxide, copper oxide and bismuth oxide, which are allo used to target different CO2RR products.

“Our method addresses a long-standing obstacle with a low-cost, easily implementable solution,” Ahmad Elgazzar, co-first author and graduate student in chemical and biomolecular engineering at Rice, added in the release. “It’s a step toward making carbon utilization technologies more commercially viable and more sustainable.”

A team led by Wang and in collaboration with researchers from the University of Houston also shared findings on salt precipitation buildup and CO2RR in a recent edition of the journal Nature Energy. Read more here.
