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 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."

Shell partners with UK-based co. for hydrogen electrolyzer pilot

ultra-efficient electrolyzer

Shell Global Solutions International, a subsidiary of Shell, which maintains its U.S. headquarters in Houston, has signed a collaboration agreement with London-based Supercritical Solutions to advance Supercritical’s ultra-efficient hydrogen electrolyzer technology toward a field pilot demonstration.

In the deal, the companies will collaborate on a paid technology feasibility study that will support the evaluation and planning of the pilot demonstration, according to a news release. Supercritical Solutions’ technology aims to deliver high-efficiency renewable hydrogen at a lower cost for the industrial hydrogen market.

"Signing this collaboration agreement with Shell is a major milestone for Supercritical Solutions and an important step on our commercialisation journey,” Luke Tan, co-founder of Supercritical, said in the news release. “We are directly addressing the cost and complexity barriers facing the renewable hydrogen market. We are excited to move forward with a company like Shell, whose global leadership has been proven to accelerate innovative technologies to market.”

Supercritical’s hydrogen electrolyser technology can operate at high temperatures and pressures of up to 220 bar without the need for an external hydrogen compressor, rare-earth materials or easily degradable membranes. The technology removes the typical compression step in the process while delivering hydrogen at industry standards. It requires significantly less energy than many traditional electrolyzers and is more cost-efficient.

This recent investment builds on an ongoing relationship between Shell and Supercritical. Supercritical was founded in 2020 and was runner-up in Shell’s New Energy Challenge, which helps startups and scaleups develop sustainable technologies, in 2021. Shell Ventures then invested in Supercritical’s Series A funding round in 2024 with Toyota Ventures.

3 Houston-area companies named to Global Cleantech 100

Three Houston-area companies—Amperon, Hertha Metals and Vaulted Deep—appear on this year’s Global Cleantech 100 list.

The unranked list, generated by market intelligence and advisory firm Cleantech Group, identifies the 100 privately held companies around the world that are most likely to make a significant impact in the cleantech market over the next five to 10 years.

For the 2026 list, Cleantech Group received more than 24,000 Global Cleantech 100 nominations from nearly 60 countries. Cleantech Group scored those companies and narrowed the contenders to 264. An expert panel reviewed those nominees, and the list was whittled down to the 100 winners.

Here’s a rundown of the three Houston-area honorees:

Amperon

Founded in 2018 by Sean Kelly and Abe Stanway, Houston-based Amperon offers an AI-enabled energy forecasting and analytics platform designed to help stabilize electric grids. Amperon received undisclosed amounts of venture capital from National Grid Partners and Tokyo Gas Co. Ltd. last year and announced a recent investment from Samsung Ventures earlier this month.

Hertha Metals

Founded in 2022 by Laureen Meroueh, Conroe-based Hertha Metals provides a single-step process for producing sustainable steel. Last year, the company emerged from stealth mode and raised more than $17 million in venture capital.

Vaulted Deep

Vaulted Deep’s technology injects excess organic waste underground to remove carbon dioxide from the atmosphere. Julia Reichelstein and Omar Abou-Sayed founded the Houston-based company in 2023. Last year, the startup raised $32.3 million in venture capital. Also in 2025, Vaulted Deep signed a 12-year deal with software giant Microsoft to remove up to 4.9 million metric tons of carbon dioxide from the environment.

Vaulted Deep also made the list last year, along with Houston-based Syzygy Plasmonics and Fervo Energy. Fervo was also named the 2025 North American Company of the Year by Cleantech Group.
