Houston has a ton of potential to be a major hub for hydrogen — but who's to pick up the tab on the progress that is needed to advance the alternative energy source? A panel at a recent event sat down to talk it out.

The Hydrogen Technology Expo, a two-day conference at NRG Center last week, brought in dozens of companies and hundreds of attendees to Houston to discuss the most pressing topics of the energy transition. One panel — moderated by Brett Perlman, CEO of the Center for Houston's Future — looked specifically at the challenges for the hydrogen economy.

The biggest challenge: Money. Perlman starts the conversation asking panelists if Wall Street is showing up to back hydrogen projects.

"Everyone talks about investing in hydrogen, and very few people actually do it," says Sean Shafer, managing partner of Energy and Industrial Advisor Partners, "outside of the big strategics and some technology plays — electrolyzers, fuel cells, and stuff like that."

Timing is an issue, adds Brian Hodges, partner at Aurum Capital Connect. Hodges, who previously was at Bank of America, saw first hand the money that a bank was willing to put into clean energy and decarbonization. But, when presenting options to deploy this funding, Hodges hears a familiar refrain — it's too early, it's too small, the pieces aren't in place yet.

"There is a gigantic pool of capital out there — whether its traditional banks, financial institutions, sovereign wealth funds," he says. "Literally everyone and their dog is interested in the space. ... We're right on the cusp of this, but when you look at Europe, they're 10 years ahead of us."

And that decade of experience is what attracts more funding, Hodges says. And it's not just Europe when it comes to markets getting ahead. Texas can't compete with the likes of California, says Roxana Bekemohammadi, founder and executive director of US Hydrogen Alliance, especially when it comes to policy. The state has had legislation addressing zero-emission vehicles since 1989.

"California policies are unique beasts, and I like to explain this because it's really important when I talk to other state legislators," Bekemohammadi says, explaining that the state mandates action and has larger teams to put policy into place. "You're looking at such a mature industry, if you want to call it an industry, but it's really a policy institution."

The panelists agree on the obstacle of policy. Tanya Peacock, managing director of EcoEngineers, works directly with project developers looking for financing and investment funds and financiers looking for projects.

"Everybody is waiting for the guidance on the IRA 45V Production Tax Credit," she says. "I think that's really the game changer for the industry, but the uncertainty around how the credit is going to be implemented is what's holding back a lot of the investment at the moment."

Texas doesn't have state incentives, Shafer points out, but the work is easy to get done with the workforce in the region, so that's also a missed opportunity. Some other factors, he adds, include offtake and lack of debt providers. He says the demand hasn't been established yet to provide a good opportunity for offtake negotiations — it's a chicken and egg problem. Meanwhile, project finance tends to have a debt provider involved, but there aren't providers willing to underwrite debt hydrogen projects.

"One of the other big things is there seems to be a lack of middle capital to get smaller companies to get their projects more backed," Shafer continues his list. "People want to write the big checks. They don't want to write the small checks — and I think one of the reasons is they don't want to lose all their capital. There's no downside protection in this industry."

Perlman, who addressed the crowd in a presentation about Texas as a hydrogen hub earlier in the day, remains bullish on the city's future in the space. Last year, CHF and several other organizations worked together to create the plan for the HyVelocity Hub — and a pitch to receive U.S. Department of Energy Regional Clean Hydrogen Hub funding to make it a reality.

"What we want to do in Texas is jumpstart the market," Perlman says, adding that HyVelocity can help accomplish this goal. "This market can happen in Texas because we are the right place with the right resources. ... What we need to do as an industry is accelerate development."

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."
