Last month, Barbara Burger participated in four panels at CERAWeek by S&P Global, and from her insider perspective, she had a few key takeaways from the event, which brought together energy leaders, tech startups, dignitaries, civil servants, and more.

In a recent podcast interview, Burger shared some of her key takeaways from the event — and how these trends are affecting the industry as a whole. Read through an excerpt or stream the full episode below.



Houston Innovators Podcast: I think most of the Houston energy world knows who you are, namely from your role leading Chevron Technology Ventures, which you left a few years ago now. So catch us up on what life looks like for you lately. I know you’re involved with a lot of organizations, so break down how you distribute your time with all of them?

Barbara Burger: The last two years since I left Chevron, I’ve built this portfolio of really interesting roles. Having been an executive for so long — executives are in there, doing stuff for the company — now, I’m an adviser or director at the company level, at the investor level, and at an investment bank, all in energy transition.

I have some challenges I want to work on that are really important to me — and those tend to not be in the for-profit space in education and performing arts.

I have some informal roles that I found I really enjoy — I mentor a wide variety of people. I have time to learn changes amid the energy transition and to attend conferences.

HIP: One of those conferences was CERAWeek last month. Why was that one important to Houston and what were your key takaways?

BB: CERAWeek is known as the "Super Bowl of Energy." It’s been going on for 40 years and really shows you the trends in energy across so many different dimensions. There’s so much in energy and you can get in your own narrow silo of working on something, and CERAWeek is an opportunity to actually see the bigger picture.

One takeaway was that it was a very practical approach. We need an energy system that focuses on climate, the economy, security — a lot of this is just the block and tackling of engineering, policy, economics, and community engagement. I think it was a practical discussion.

The other is that everybody has woken up and realized that our load growth — our demand — is growing, and because of all kinds of things pointing toward electrification. I think that the big one in the room was AI and the power demands for it.

It’s not just about the innovation — it’s really about scaling that innovation and that execution, because that’s when we get impact, when these technologies are actually used in the energy system, and when we create new businesses. It’s going to take investment, capabilities, a real understanding of the marketplace, and, in many cases, it’s going to take a relationship with the government.

Philanthropists were there, but I wish I'd seen more of a presence from private equity. Every year I see more people from outside of what I would call the conventional energy industry, and I think that’s really good.

There’s a lot pools of capital, and they’re different and siloed, and they even use different vocabulary. Making those transitions is really important. That’s where I think the private equity investors play a role here, and venture and private equity — those are two different places, but we’re starting to see collaboration between them.

HIP: The United States Department of Energy had a notable presence at CERAWeek this year. What do you think about the organization's efforts and recent approach to 

BB: In years gone by, DOE funding was much more focused on early stuff — research and development. We all know that if you cannot scale and put technologies into operation, you do not get the impact. So the DOE has developed programs to focus and deployments.

They aren’t trying to replace private capital, but they are trying to be catalytic — which is also a role philanthropists are doing. Go in where the market won’t make the right call to buy down some of the uncertainty. They've been really collaborative and have skin in the game on this one.

HIP: What keeps you up at night when you think of the future of energy?

BB: One of the biggest risks is that we do not act fast enough, and what I mean is that we somehow convince ourselves that we do not need to evolve — and that’s as companies, as a nation, or as a globe.

We’ve made tremendous progress in 10 years. But I believe that in 2050 that we will look back and say, "why didn’t we start earlier and why weren’t we consistent with our actions." The energy transition gets politicized, and we don’t move with conviction.

HIP: What about the role Houston plays in all of this?

BB: I've been bullish on Houston in the energy transition. I moved here 11 years ago, and I had no companies in my portfolio in CTV from Houston, and I wondered why. There are a few things I’m proud of in the ecosystem here, and one of theme is that it’s a very inclusive ecosystem — and I mean that there's all different startups — student founded, operator founded, and incumbent companies at the table, but the worst way to get people to not join a party is to not invite them.

No one company or organization is going to solve this. We have to get along. We have to stop thinking that the mode is to compete with each other because the pie is so big and the opportunity is so big to work together — and by and large I do see that happening.

Engineers at Rice University have developed a cleaner, innovative process to turn end-of-life lithium-ion battery waste into new lithium feedstock.

The findings, recently published in the journal Joule, demonstrate how the team’s new “recharge-to-recycle” reactor recharges the battery’s waste cathode materials to coax out lithium ions into water. The team was then able to form high-purity lithium hydroxide, which was clean enough to feed directly back into battery manufacturing.

The study has major implications for the electric vehicle sector, which significantly contributes to the waste stream from end-of-life battery packs. Additionally, lithium tends to be expensive to mine and refine, and current recycling methods are energy- and chemical-intensive.

“Directly producing high-purity lithium hydroxide shortens the path back into new batteries,” Haotian Wang, associate professor of chemical and biomolecular engineering, co-corresponding author of the study and co-founder of Solidec, said in a news release. “That means fewer processing steps, lower waste and a more resilient supply chain.”

Sibani Lisa Biswal, chair of Rice’s Department of Chemical and Biomolecular Engineering and the William M. McCardell Professor in Chemical Engineering, also served as co-corresponding author on the study.

“We asked a basic question: If charging a battery pulls lithium out of a cathode, why not use that same reaction to recycle?” Biswal added in the release. “By pairing that chemistry with a compact electrochemical reactor, we can separate lithium cleanly and produce the exact salt manufacturers want.”

The new process also showed scalability, according to Rice. The engineers scaled the device to 20 square centimeters, then ran a 1,000-hour stability test and processed 57 grams of industrial black mass supplied by industry partner Houston-based TotalEnergies. The results produced lithium hydroxide that was more than 99 percent pure. It also maintained an average lithium recovery rate of nearly 90 percent over the 1,000-hour test, showing its durability. The process also worked across multiple battery chemistries, including lithium iron phosphate, lithium manganese oxide and nickel-manganese-cobalt variants.

Looking ahead, the team plans to scale the process and consider ways it can sustain high efficiency for greater lithium hydroxide concentrations.

“We’ve made lithium extraction cleaner and simpler,” Biswal added in the release. “Now we see the next bottleneck clearly. Tackle concentration, and you unlock even better sustainability.
