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."

Gold H2 harvests clean hydrogen from depleted California reservoirs in first field trial

breakthrough trial

Houston climatech company Gold H2 completed its first field trial that demonstrates subsurface bio-stimulated hydrogen production, which leverages microbiology and existing infrastructure to produce clean hydrogen.

Gold H2 is a spinoff of another Houston biotech company, Cemvita.

“When we compare our tech to the rest of the stack, I think we blow the competition out of the water," Prabhdeep Singh Sekhon, CEO of Gold H2 Sekhon previously told Energy Capital.

The project represented the first-of-its-kind application of Gold H2’s proprietary biotechnology, which generates hydrogen from depleted oil reservoirs, eliminating the need for new drilling, electrolysis or energy-intensive surface facilities. The Woodlands-based ChampionX LLC served as the oilfield services provider, and the trial was conducted in an oilfield in California’s San Joaquin Basin.

According to the company, Gold H2’s technology could yield up to 250 billion kilograms of low-carbon hydrogen, which is estimated to provide enough clean power to Los Angeles for over 50 years and avoid roughly 1 billion metric tons of CO2 equivalent.

“This field trial is tangible proof. We’ve taken a climate liability and turned it into a scalable, low-cost hydrogen solution,” Sekhon said in a news release. “It’s a new blueprint for decarbonization, built for speed, affordability, and global impact.”

Highlights of the trial include:

  • First-ever demonstration of biologically stimulated hydrogen generation at commercial field scale with unprecedented results of 40 percent H2 in the gas stream.
  • Demonstrated how end-of-life oilfield liabilities can be repurposed into hydrogen-producing assets.
  • The trial achieved 400,000 ppm of hydrogen in produced gases, which, according to the company,y is an “unprecedented concentration for a huff-and-puff style operation and a strong indicator of just how robust the process can perform under real-world conditions.”
  • The field trial marked readiness for commercial deployment with targeted hydrogen production costs below $0.50/kg.

“This breakthrough isn’t just a step forward, it’s a leap toward climate impact at scale,” Jillian Evanko, CEO and president at Chart Industries Inc., Gold H2 investor and advisor, added in the release. “By turning depleted oil fields into clean hydrogen generators, Gold H2 has provided a roadmap to produce low-cost, low-carbon energy using the very infrastructure that powered the last century. This changes the game for how the world can decarbonize heavy industry, power grids, and economies, faster and more affordably than we ever thought possible.”

Rice University spinout lands $500K NSF grant to boost chip sustainability

cooler computing

HEXAspec, a spinout from Rice University's Liu Idea Lab for Innovation and Entrepreneurship, was recently awarded a $500,000 National Science Foundation Partnership for Innovation grant.

The team says it will use the funding to continue enhancing semiconductor chips’ thermal conductivity to boost computing power. According to a release from Rice, HEXAspec has developed breakthrough inorganic fillers that allow graphic processing units (GPUs) to use less water and electricity and generate less heat.

The technology has major implications for the future of computing with AI sustainably.

“With the huge scale of investment in new computing infrastructure, the problem of managing the heat produced by these GPUs and semiconductors has grown exponentially. We’re excited to use this award to further our material to meet the needs of existing and emerging industry partners and unlock a new era of computing,” HEXAspec co-founder Tianshu Zhai said in the release.

HEXAspec was founded by Zhai and Chen-Yang Lin, who both participated in the Rice Innovation Fellows program. A third co-founder, Jing Zhang, also worked as a postdoctoral researcher and a research scientist at Rice, according to HEXAspec's website.

The HEXASpec team won the Liu Idea Lab for Innovation and Entrepreneurship's H. Albert Napier Rice Launch Challenge in 2024. More recently, it also won this year's Energy Venture Day and Pitch Competition during CERAWeek in the TEX-E student track, taking home $25,000.

"The grant from the NSF is a game-changer, accelerating the path to market for this transformative technology," Kyle Judah, executive director of Lilie, added in the release.
