Here are five things to know from CERAWeek this year. Photo courtesy of CERAWeek

The 2024 edition of CERAWeek by S&P Global wrapped up last Friday in Houston, and a handful of themes emerged as topical and disruptive amid the energy transition.

Here are five takeaways from the conference, according to EnergyCapital reporting.

Funding the energy transition continues to be a challenge.

The biggest obstacle to the energy transition is — and might always be — funding it. A panel at Agora on Thursday, March 21, moderated by Barbara Burger set out to discuss the role of venture capital amid the future of energy.

Daniel Goldman, managing partner at Clean Energy Ventures, said that the first plants for these new, revolutionary technologies are going to be more expensive than its subsequent plants.

"But you have to built it," Goldman says. "'First of a kind' can be very different from the end plant, because you need to manage risk. ... But those first plants are going to be quite costly, and you're going to have to recognize that as an investor."

Microsoft and Breakthrough Ventures Founder Bill Gates would address this in his talk later that day, pointing out that traditional infrastructure investors are used to knowing what a plant would cost before its built. But in clean tech, outside of solar and wind, there's too much unknown to give the estimation those investors are looking for.

"Nothing's at the maturity level that you can do that," Gates says.

The DOE's role of de-risking green tech.

The United States Department of Energy had a significant presence at CERAWeek, with Secretary of Energy Jennifer M. Granholm making two major announcements on Monday, March 18, the first day of the conference. One of the announcements was the DOE's latest Pathways to Commercial Liftoff report, which are initiatives established to provide investors with information of how specific energy technologies commercialize and what challenges they each have to overcome as they scale.

"We develop these Liftoff Reports through a combination of modeling and hundreds and hundreds of interviews with people across the whole investment lifecycle—from early-stage capital to commercial banks and institutional investors," Granholm says in her address, announcing geothermal energy as the subject of the ninth report.

Intended to "create a common fact base and a tool for ongoing dialogue with the private sector on the pathways to commercial liftoff," according to the DOE, these reports can be instrumental for enterprises in the field.

A panel at Agora on Thursday, March 21, featuring geothermal energy innovators discussed the impact of the report. Tim Latimer, CEO and founder of Houston-based Fervo Energy, says the report included details from his company's work.

To Latimer, the report showcases geothermal energy's ability to compete from a cost perspective.

"I think geothermal is already winning that cost discussion," Latimer says. "You're talking about $45 per megawatt hour unsubsidized cost for round-the-clock, 24/7 carbon-free energy. I think that's an achievable ambition the DOE set out, and I think it's an unbeatable value proposition.

Hot topic: Geothermal energy.

Geothermal energy was discussed throughout the week following Granholm's address, in part because of its expected cost efficiency, but also because it's a type of energy that should provide a smooth transition from traditional oil and gas.

John Redfern, CEO of Eavor Technologies, global geothermal technology company headquartered in Canada, says on the geothermal panel that the geothermal industry can build off existing infrastructure.

"Most of it is building blocks that we're recycling from the oil industry — resources, people, technologies," Redfern says. "So, it's more about implementing rather than inventing some new, novel product."

Latimer agrees, adding that Fervo "is fully in the deployment phase."

"The breakthrough needed to make geothermal ready for primetime have already happened," Latimer says.

AI is everywhere — especially the energy transition.

The topic of artificial intelligence was everywhere, so much that by Thursday, panelists joked about every discussion including at least one mention of the technology.

Gates was one speaker who addresses the subject, which isn't all too surprising, since Microsoft owns a portion of OpenAI, which created ChatGPT. One thing left to be known is how directly AI will affect the energy transition — and on what timeline.

AI's current applications are within white collar activities, Gates explains, citing writing a regulatory permit or looking at evidence in a lawsuit. He explains that current AI capabilities could continually grow or remain stagnant for a while, he isn't sure.

"The thing that’s daunting is we don’t know how quickly it will improve," he adds.

Gates didn't comment on energy specific AI applications but noted that AI has advanced far past robotics, which would target blue collar roles.

Big tech sees green.

And speaking of AI, big tech companies have been making moves to lower carbon footprints, and that was made clear by the activations at CERAWeek. Microsoft and Amazon each had designated houses at the conference, alongside Oxy, Chevron, Aramco, and other traditional energy players.

At Microsoft, Houston-based Amperon, which recently announced a partnership with the tech company, presented and pitched their company. The Microsoft and Amazon houses showcased each company's low-carbon technologies.

Chevron CEO touts biofuels as part of its renewable energy efforts

Betting on biofuels

As Chevron Chairman and CEO Mike Wirth surveys the renewable energy landscape, he sees the most potential in biofuels.

At a recent WSJ CEO Council event, Wirth put a particular emphasis on biofuels—the most established form of renewable energy—among the mix of low-carbon energy sources. According to Biofuels International, Chevron operates nine biorefineries around the world.

Biofuels are made from fats and oils, such as canola oil, soybean oil and used cooking oil.

At Chevron’s renewable diesel plant in Geismar, Louisiana, a recent expansion boosted annual production by 278 percent — from 90 million gallons to 340 million gallons. To drive innovation in the low-carbon-fuels sector, Chevron opened a technology center this summer at its renewable energy campus in Ames, Iowa.

Across the board, Chevron has earmarked $8 billion to advance its low-carbon business by 2028.

In addition to biofuels, Chevron’s low-carbon strategy includes hydrogen, although Wirth said hydrogen “is proving to be very difficult” because “you’re fighting the laws of thermodynamics.”

Nonetheless, Chevron is heavily invested in the hydrogen market:

As for geothermal energy, Wirth said it shows “some real promise.” Chevron’s plans for this segment of the renewable energy industry include a 20-megawatt geothermal pilot project in Northern California, according to the California Community Choice Association. The project is part of an initiative that aims to eventually produce 600 megawatts of geothermal energy.

What about solar and wind power?

“We start with things where we have some reason to believe we can create shareholder value, where we’ve got skills and competency, so we didn’t go into wind or solar because we’re not a turbine manufacturer installing wind and solar,” he said in remarks reported by The Wall Street Journal.

In a September interview with The New York Times, Wirth touched on Chevron’s green energy capabilities.

“We are investing in new technologies, like hydrogen, carbon capture and storage, lithium and renewable fuels,” Wirth said. “They are growing fast but off a very small base. We need to do things that meet demand as it exists and then evolve as demand evolves.”

Houston robotics company partners with Marathon Petroleum to scale fleet

Houston- and Boston-based Square Robot Inc. has announced a partnership with downstream and midstream energy giant Marathon Petroleum Corp. (NYSE: MPC).

The partnership comes with an undisclosed amount of funding from Marathon, which Square Robot says will help "shape the design and development" of its submersible robotics platform and scale its fleet for nationwide tank inspections.

“Marathon’s partnership marks a major milestone in our mission to transform industrial tank inspection,” David Lamont, CEO of Square Robot, said in a news release. “They recognize the proven value of our robotic inspections—eliminating confined space entry, reducing the environmental impact, and delivering major cost efficiencies all while keeping tanks on-line and working. We’re excited to work together with such a great company to expand inspection capabilities and accelerate innovation across the industry.”

The company closed a $13 million series B last year. At the time of closing, Square Robot said it would put the funding toward international expansion in Europe and the Middle East.

Square Robot develops autonomous, submersible robots that are used for storage tank inspections and eliminate the need for humans to enter dangerous and toxic environments. Its newest tank inspection robot, known as the SR-3HT, became commercially available and certified to operate at a broader temperature range than previous models in the company's portfolio this fall.

The company was first founded in the Boston area in 2016 and launched its Houston office in 2019.
