4 Houston energy execs sound off on future workforce, collaboration, and more at OTC

overheard

In addition to the massive exhibit floor, networking, and panels, the 2024 Offshore Technology Conference hosts thoughtful fireside chats with energy leaders throughout the ongoing conference taking place in Houston this week.

Four energy leaders from Houston took the stage to discuss what their companies are doing within the energy transition. Take a look at what topics each of the conversations tackled.

Chris Powers, vice president of CCUS at Chevron New Energies, on energy evolution and collaboration

Chris Powers introduced Chevron New Energies, an organization within Chevron that launched in 2021, to the crowd at OTC, describing the entity's focus points as CCUS, hydrogen, offsets and emerging technology, and renewable fuels — specifically things Chevron believes it has the competitive advantage.

One of the things Powers made clear in his fireside chat is that it's not going to be one, two, or even three technologies to significantly move the energy transition along, "it's going to take all the solutions to meet all the growing energy needs," he said.

And, he continued, this current energy transition the world is in isn't exactly new.

"We've been evolving our energy supply since the dawn of man," he said. "Our view is that the world has always been in an energy evolution."

"Hydrocarbons will continue to play a huge role in the years to come, and anyone who has a different view on that I think isn't being pragmatic," he continued.

Chevron has played a role in the clean energy market for decades, Powers said, pointing out Chevron Technology Ventures, which launched in the 1990s.

"No one can do this alone," he said, pointing specifically to the ongoing Bayou Bend joint venture that Chevron is working on with Equinor and TotalEnergies. "We have to bring together the right partners and the right skill sets."

Celine Gerson, group director, Americas, and president at Fugro USA, on the importance of data

Celine Gerson set the scene for Fugro, a geo data and surveying company that diversified its business beginning in 2015 to account for the energy transition. From traditional oil and gas to renewables, "it starts with the geo data," she said during her chat. She said big projects can't map out their construction without it, and then, when it comes to maintaining the equipment, the geo data is equally important.

Another message Gerson wanted to convey is that the skill sets from traditional offshore services translate to renewables. Fugro's employee base has evolved significantly over the past few years, and Gerson said that 50 percent of the workforce was hired over the past five years and 85 percent of the leadership has changed in the past seven.

Agility is what the industry needs, Celine Gerson said, adding that the "industry need to move fast and, in order to move fast, we need to look at things differently.

Attilio Pisoni, CTO of oilfield services and equipment at Baker Hughes, on the future workforce

In addition to the world making changes toward sustainability, the energy industry is seeing a workforce evolution as well, Attilio Pisoni said during his fireside chat, adding that inspiring a workforce is key to retention and encouraging innovation.

"We have a challenge in attracting young people," Pisoni said. "To be successful, you have to have a purpose."

That purpose? Combating climate change. And that, Pisoni said, needs to be able to be quantified. "As a society over all, we need to have a standard of measurement and accuracy in reporting," he said.

To future engineers, Pisoni emphasized the importance of learning outside your specific niche.

"Having seen where the world is now, whatever you study, have a concept and understanding of the system as a whole," he said.

Erik Oswald, vice president of advocacy and policy development at ExxonMobil Low Carbon Solutions, on transferable skills from upstream

When he looks at renewables and new energy, Erik Oswald said he sees a significant similarity for the talent and skill sets required in upstream oil and gas.

"A lot of the same skills are coming into focus" within the energy transition," Oswald said, specifying CCS and upstream.

Even in light of the transferrable workforce, the industry faces needs to grow its workforce in a significant way to keep up with demand — and keeping in mind the younger generations coming onto the scene.

"We're talking about recreating the entire oil and gas industry," Oswald said on preparing the workforce for the future of the energy industry. "We have to do it, it's not an option."

Houston geothermal company raises $97M Series B

fresh funding

Houston-based geothermal energy startup Sage Geosystems has closed its Series B fundraising round and plans to use the money to launch its first commercial next-generation geothermal power generation facility.

Ormat Technologies and Carbon Direct Capital co-led the $97 million round, according to a press release from Sage. Existing investors Exa, Nabors, alfa8, Arch Meredith, Abilene Partners, Cubit Capital and Ignis H2 Energy also participated, as well as new investors SiteGround Capital and The UC Berkeley Foundation’s Climate Solutions Fund.

The new geothermal power generation facility will be located at one of Ormat Technologies' existing power plants. The Nevada-based company has geothermal power projects in the U.S. and numerous other countries around the world. The facility will use Sage’s proprietary pressure geothermal technology, which extracts geothermal heat energy from hot dry rock, an abundant geothermal resource.

“Pressure geothermal is designed to be commercial, scalable and deployable almost anywhere,” Cindy Taff, CEO of Sage Geosystems, said in the news release. “This Series B allows us to prove that at commercial scale, reflecting strong conviction from partners who understand both the urgency of energy demand and the criticality of firm power.”

Sage reports that partnering with the Ormat facility will allow it to market and scale up its pressure geothermal technology at a faster rate.

“This investment builds on the strong foundation we’ve established through our commercial agreement and reinforces Ormat’s commitment to accelerating geothermal development,” Doron Blachar, CEO of Ormat Technologies, added in the release. “Sage’s technical expertise and innovative approach are well aligned with Ormat’s strategy to move faster from concept to commercialization. We’re pleased to take this natural next step in a partnership we believe strongly in.”

In 2024, Sage agreed to deliver up to 150 megawatts of new geothermal baseload power to Meta, the parent company of Facebook. At the time, the companies reported that the project's first phase would aim to be operating in 2027.

The company also raised a $17 million Series A, led by Chesapeake Energy Corp., in 2024.

Houston expert discusses the clean energy founder's paradox

Guest Column

Everyone tells you to move fast and break things. In clean energy, moving fast without structural integrity means breaking the only planet we’ve got. This is the founder's paradox: you are building a company in an industry where the stakes are existential, the timelines are glacial, and the capital requires patience.

The myth of the lone genius in a garage doesn’t really apply here. Clean energy startups aren’t just fighting competitors. They are fighting physics, policy, and decades of existing infrastructure. This isn’t an app. You’re building something physical that has to work in the real world. It has to be cheaper, more reliable, and clearly better than fossil fuels. Being “green” alone isn’t enough. Scale is what matters.

Your biggest risks aren’t competitors. They’re interconnection delays, permitting timelines, supply chain fragility, and whether your first customer is willing to underwrite something that hasn’t been done before.

That reality creates a brutal filter. Successful founders in this space need deep technical knowledge and the ability to execute. You need to understand engineering, navigate regulation, and think in terms of markets and risk. You’re not just selling a product. You’re selling a future where your solution becomes the obvious choice. That means connecting short-term financial returns with long-term system change.

The capital is there, but it’s smarter and more demanding. Investors today have PhDs in electrochemistry and grid dynamics. They’ve been burned by promises of miracle materials that never left the lab. They don't fund visions; they fund pathways to impact that can scale and make financial sense. Your roadmap must show not just a brilliant invention, but a clear, believable plan to drive costs down over time.

Capital in this sector isn’t impressed by ambition alone. It wants evidence that risk is being retired in the right order — even if that means slower growth early.

Here’s the upside. The difficulty of clean energy is also its strength. If you succeed, your advantage isn’t just in software or branding. It’s in hardware, supply chains, approvals, and years of hard work that others can’t easily copy. Your real competitors aren’t other startups. They’re inertia and the existing system. Winning here isn’t zero-sum. When one solution scales, it helps the entire market grow.

So, to the founder in the lab, or running field tests at a remote site: your pace will feel slow. The validation cycles are long. But you are building in the physical world. When you succeed, you don’t have an exit. You have a foundation. You don't just have customers; you have converts. And the product you ship doesn't just generate revenue; it creates a legacy.

If your timelines feel uncomfortable compared to software, that’s because you’re operating inside a system designed to resist change. And let’s not forget you are building actual physical products that interact with a complex world. Times are tough. Don’t give up. We need you.

Houston maritime startup raises $43M to electrify cargo vessels

A Houston-based maritime technology company that is working to reduce emissions in the cargo and shipping industry has raised VC funding and opened a new Houston headquarters.

Fleetzero announced that it closed a $43 million Series A financing round this month led by Obvious Ventures with participation from Maersk Growth, Breakthrough Energy Ventures, 8090 Industries, Y Combinator, Shorewind, Benson Capital and others. The funding will go toward expanding manufacturing of its Leviathan hybrid and electric marine propulsion system, according to a news release.

The technology is optimized for high-energy and zero-emission operation of large vessels. It uses EV technology but is built for maritime environments and can be used on new or existing ships with hybrid or all-electric functions, according to Fleetzero's website. The propulsion system was retrofitted and tested on Fleetzero’s test ship, the Pacific Joule, and has been deployed globally on commercial vessels.

Fleetzero is also developing unmanned cargo vessel technology.

"Fleetzero is making robotic ships a reality today. The team is moving us from dirty, dangerous, and expensive to clean, safe, and cost-effective. It's like watching the future today," Andrew Beebe, managing director at Obvious Ventures, said in the news release. "We backed the team because they are mariners and engineers, know the industry deeply, and are scaling with real ships and customers, not just renderings."

Fleetzero also announced that it has opened a new manufacturing and research and development facility, which will serve as the company's new headquarters. The facility features a marine robotics and autonomy lab, a marine propulsion R&D center and a production line with a capacity of 300 megawatt-hours per year. The company reports that it plans to increase production to three gigawatt-hours per year over the next five years.

"Houston has the people who know how to build and operate big hardware–ships, rigs, refineries and power systems," Mike Carter, co-founder and COO of Fleetzero, added in the release. "We're pairing that industrial DNA with modern batteries, autonomy, and software to bring back shipbuilding to the U.S."
