The energy industry in Houston, Texas, and beyond is gearing up for new opportunities within the energy transition, as a recent Houston event and its lineup of experts shared.

At the inaugural ENERGYEAR USA 2023, panelists outlined how their companies are opting into a more personable approach to building sustainable energy solutions – and sustainable communities.

“Most of our renewable projects are in very rural areas. We come to communities that don’t have enough money to invest in their schools, their kids. There’s not a lot of opportunity,” explains David Carroll, chief renewables officer and senior vice president of the North America region for Engie.

“We come in and invest a lot in the construction phase, but after that, we have workers that live there. We are often one of the largest taxpayers in that area,” Carroll continues. “We can provide them cash profit, provide them the tax base, so that we can help provide a future in many of these rural communities that were struggling before we got there.”

Engie, which has closed several coal plants globally ahead of schedule to work toward meeting their commitment to Net Zero by 2045, isn’t the only organization that emphasizes purpose in its pursuit of energy equity.

Power Electronics, the global leader in renewable energy storage, finds purpose through re-purposing field technicians. For the past five years, the organization has transformed talent with electrical equipment experience from the oil and gas industry into renewables. The company doesn’t plan on slowing down, either.

“We are proud to announce here today [that over] the next two years, we will create more than 500 jobs as the largest ever manufacturer of solar inverter and intermediate scale battery inverters in the U.S.,” shares David Salvo, CEO of Power Electronics. “We start manufacturing EV chargers in Houston later this year and are committed to U.S. manufacturing job creation.”

The company saw a need for setting up a Texas manufacturing facility to support growth and was impressed by the volume of Houston talent possessing a deep understanding of both mechanical and electrical equipment from their tenure in upstream oil and gas.

“It is easier to find people here [like that] than anywhere else,” Salvo tells EnergyCapitalHTX. “That is a fact.”

Explosive growth for the region has barely even begun, with expected investments in Texas alone exceeding $60 billion dollars in large scale renewables.

“Because of these investments that we are making, we are able to create good paying jobs… and meet climate goals of getting to a Net Zero economy by 2050,” Jeff Marootian, U.S Department of Energy senior advisor, tells Katie Mehnert, CEO of Ally Energy and DOE Ambassador, during their fireside chat.

“Partnership between government and private sector, ultimately, is creating these opportunities,” Marootian says. “Our challenge is to help identify, help train, help build up that generation of workforce.”

As a final note on the trifecta of purpose, partnering, and governance, Erika Bierschbach, vice president of energy market operations and resource planning for Austin Energy, challenges the power and utilities industry to embrace statistical models over deterministic ones when forecasting energy supply and demand. The upstream oil and gas sector embraced this practice years ago to improve production optimization processes.

On the subject of green energy employment, a recent report found that Houston is a successful hub when it comes to clean energy jobs. SmartAsset, a personal finance website, recently ranked the Houston metro area as the fifth best place in the U.S. for green jobs, which pay an average of 21 percent more than other jobs. And actually, the study found that 2.23 percent of workers in the Houston area hold down jobs classified as “green.”

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."
