Houston-based material science and climatech startup DexMat has closed a $5 million seed round.

The round was led by non sibi ventures, with participation from Governance Partners, Tailwind Futures, BetterWay, Capital Factory and other investors. The company additionally announced that it has secured $3 million of non-dilutive funding.

DexMat plans to use the recent round to commercially scale Galvorn, its carbon-based conductive fiber. The high-performance copper alternative, originally developed at Rice University, is made from carbon nanotube (CNT) fibers, which are less energy- and CO2-intensive to produce.

The company says it will grow its technical and commercial teams and advance pilot-scale production to meet demand from new and existing customers in aerospace, defense and manufacturing industries.

"We’re seeing clear customer pull, particularly in wire and cable applications, as manufacturers look for conductive materials that are less dense, more durable, and resilient at scale,” Bryan Guido Hassin, CEO of DexMat, said in a news release. “This funding allows us to meet near-term demand and expand production capabilities in response to evolving supply-chain constraints."

The recent funding comes after a year of impressive growth. According to the news release, DexMat more than doubled its production and sales of Galvorn in 2025 compared to the previous year.

“We consistently hear the same message from customers: the material performs really well, and they need more of it at a lower cost,” Dmitri Tsentalovich, co-founder and CTO of DexMat, added in the release. “This round supports the production scale-up and cost reductions required to move Galvorn into broader commercial use.”

DexMat raised $3 million in funding in a round led by Shell Ventures in 2023. The company reports a 20-fold increase in capacity since its pre-seed round, along with a 96 percent reduction in production costs.

DexMat's technology was originally developed in the Rice University lab of co-founder Matteo Pasquali, who also serves as director of Rice’s Carbon Hub. According to previous reports, the company was built on over $20 million in non-dilutive funding—including grants from the Air Force Research Laboratory, Air Force Office of Scientific Research, U.S. Department of Energy, NASA, Advanced Functional Fabrics of America and the National Science Foundation—with Rice University included in the list of original investors.

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.

What is it going to take to make Houston a leader in the energy transition? Access to capital, according to a panel from Venture Houston. Photo by Natalie Harms/EnergyCapital

Experts: Houston needs to unlock early-stage capital to lead the energy transition

show me the money

Last week, Tim Latimer sat on a panel that consisted mostly of his company's investors and discussed what he felt the missing piece still was for Houston's energy transition and innovation community.

“There’s no better place in the world than Houston to build and scale a climate tech startup," he says on a Venture Houston panel titled Seeding Sustainability: Unlocking the Power of Early Stage Investments.

“But I don’t know if I’m ready to make the claim that we’re the best place to start a business,” he adds.

Latimer, who co-founded Fervo Energy in the Bay Area in 2017 before relocating the company to Houston, explains that his company raised capital on the West Coast ahead of moving to Texas to grow and scale. This allowed the company, which recently announced the success of a major pilot, to tap into early stage funding and then make the most of every dollar raised by moving to a region where the money would last longer — and where there's talent, customers, and more.

“The dream for us to have a truly unlocked ecosystem is that the whole pattern can happen here in Houston, and the gap I see is that capital formation side,” he says.

Latimer was joined on the panel by some of Fervo's investors: Mark Cupta, managing partner of Prelude Ventures; Andrea Course, venture principal of Shell Ventures; and Joshua Posamentier, co-founder and managing partner of Congruent Ventures.

Each of the panelists weighed in on what it would take for Houston to emerge as a leader within the global energy transition. Cupta says that it's going to take the city time to build out activity, successful outcomes, talent, money, and more.

“The venture capital community is an ecosystem, and that ecosystem consists of multiple stakeholders that all have to work in concert with each other," he says. "It has to be a flywheel that spins up over time.”

Course, the only Houston-based investor on the panel, says that Houston has potential because it's got talent, industry, and money, or TIM, as she describes.

“I think Houston is actually the perfect place for becoming the energy transition capital. If you ask me, I think we already are.” Course explains. “It really just takes people doing what we’re doing now to make it even greater."

Posamentier, who previously shared his outlook on Houston in a Q&A with EnergyCapital, explains that access to funding isn't the only issue. “There’s a lot more money than there are investable opportunities at the moment,” he says.

The panel also weighed in on the difference between venture capital and funding coming out of corporations.

“VCs and CVCs have different timelines,” Course explains, saying VC firms have 5- to 7-year life cycles. After that, they need to see an exit to be able to provide that return. “With a CVC, we don’t really have that. Of course we want to show financial returns, but we are long-duration capital.

CVC is patient capital with value-add investors, but Course admits there's a longer due diligence because she wants to find a strategic stakeholder before an investment is made.

“The worst thing that could happen is that Shell gives you money, but they don’t give you business. We don’t want that,” she says.

Waiting for that right investor can be extremely important to company success, Latimer says from the founder perspective.

“It’s hard to put a hard dollar value on help, but our ability to have advisers and introductions from different types of investors … makes all the difference in the world,” he says on the panel. “A lot of startup founders think about their org design very critically and who they want to bring onto the team, and you should be deliberate on your cap table.”

Texas' oil and gas foundation could boost its geothermal future, UH says

future of geothermal

Equipped with the proper policies and investments, Texas could capitalize on its oil and gas infrastructure and expertise to lead the U.S. in development of advanced geothermal power, a new University of Houston white paper says.

Drilling, reservoir development and subsurface engineering are among the Texas oil and gas industry’s capabilities that could translate to geothermal energy, according to a news release. Furthermore, oil and gas skills, data, technology and supply chains could help make geothermal power more cost-effective.

Up to 80 percent of the investment required for a geothermal project involves capacity and skills that are common in the oil and gas industry, the white paper points out.

Building on its existing oil-and-gas foundation, Texas could help accelerate production of geothermal energy, lower geothermal energy costs and create more jobs in the energy workforce, according to the news release.

The paper also highlights geothermal progress made by Houston-based companies Fervo Energy, Quaise Energy and Sage Geosystems, as well as Canada-based Eavor Technologies Inc.

UH’s Division of Energy published the white paper, Advanced Geothermal: Opportunities and Challenges, in partnership with the C.T. Bauer College of Business’ Gutierrez Energy Management Institute.

“Energy demand, especially electricity demand, is continuing to grow, and we need to develop new low-carbon energy sources to meet those needs,” Greg Bean, executive director of the institute and author of the white paper, said of geothermal’s potential.

HETI leader reflects on four years focused on the energy transition

The View From HETI

It’s hard to believe only four years have passed since I joined the Greater Houston Partnership to lead the Houston Energy Transition Initiative. We talk about COVID years feeling simultaneously like just yesterday and a lifetime ago, and my time at HETI feels quite similar. The energy and climate landscape has evolved dramatically over the last few years, but one constant has endured…Houston remains at the heart of the energy industry.

When I joined HETI at the start of 2022, I could not have imagined the impact we would have over the next four years. Our vision, laid out in 2020 by then Partnership Chair Bobby Tudor, was bold – leverage Houston’s energy leadership to accelerate global solutions for an energy abundant, low-carbon future. Our mission was clear – ensure the long-term economic competitiveness of the Houston region in a changing energy landscape. Our strategy, developed with strong support from McKinsey, was sound – build a coalition of industry, academic and community partners to position Houston as a leading hub for energy and climate innovation, commercialization and economic growth.

And Houston’s energy leaders, across business, academia and community, came together to deliver that strategy. Bobby Tudor’s timely vision created an anchor for Houston’s energy community that allowed us to broaden the energy and climate discussion to one focused on meeting growing energy demand and reducing emissions. That vision was a catalyst for changing the perception of Houston from oil & gas capital to an “all of the above” energy capital with a thriving energy and climate tech innovation ecosystem. Houston is where you can work collaboratively to build new energy value chains and ensure an affordable, secure, and lower emissions energy mix for our region, our country, and the world.

In this fast-moving energy environment, it can be easy to focus on what to do next without taking time to reflect on the work and celebrate the wins. We took the opportunity at the end of 2025 to reflect on five years of impact. As we developed that report, I thought about how fortunate I have been to lead this work for the last four years. HETI’s impact has been incredibly meaningful for our region, our members, and the new companies and founders building the next generation of energy technology and talent. As my time as executive director comes to an end, HETI’s work continues. The need remains clear: more energy, less emissions, and continued collaboration that brings together innovation and infrastructure, policies and markets, and hard tech together with human ingenuity.

As I prepare to hand the reigns to HETI’s new SVP and executive cirector, Sophia Cunningham, at the end of March, I have been reflecting on the impact this role has had on me. Four years ago, I could never have imagined the opportunities, experiences and relationships this role has enabled. I am truly grateful for the support and engagement of Houston’s business and community leaders, the visionary leadership of Bobby Tudor, Scott Nyquist, HETI Members, and the Greater Houston Partnership in creating this initiative at exactly the right moment in time. I am incredibly proud of the HETI and partnership team members who have delivered with purpose and passion, and I greatly appreciate Houston’s energy and climate leaders and champions who have supported my agenda, challenged my thinking, broadened my perspectives, and worked with HETI to demonstrate the power of partnership in developing, innovating and advancing the ideas and technologies needed to meet this challenge for our region and the world.

As excited as I am to see where this next chapter takes me, I am even more excited to see where the work of HETI goes from here. I am still optimistic that the challenge of providing the world with affordable, reliable, and resilient energy while simultaneously reducing emissions is one Houston is uniquely positioned to meet.

Texas could topple Virginia as biggest data-center market by 2030, JLL report says

data analysis

Everything’s bigger in Texas, they say—and that phrase now applies to the state’s growing data-center presence.

A new report from commercial real estate services provider JLL says Texas could overtake Northern Virginia as the world’s largest data-center market by 2030. Northern Virginia is a longtime holder of that title.

What’s driving Texas’ increasingly larger role in the data-center market? The key factor is artificial intelligence.

Companies like Google and Microsoft need more energy-hungry data centers to power AI innovations. In a 2023 article, Forbes explained that AI models consume a lot of energy because of the massive amount of data used to train them, as well as the complexity of those models and the rising volume of tasks assigned to AI.

“The data-center sector has officially entered hyperdrive,” Andy Cvengros, executive managing director at JLL and co-leader of its U.S. data-center business, said in the report. “Record-low vacancy sustained over two consecutive years provides compelling evidence against bubble concerns, especially when nearly all our massive construction pipeline is already pre-committed by investment-grade tenants.”

Dallas-Fort Worth has long dominated the Texas data-center market. But in recent years, West Texas has emerged as a popular territory for building data-center campuses, thanks in large part to an abundance of land and energy. Nearly two-thirds of data-center construction underway now is happening in “frontier markets” like West Texas, Ohio, Tennessee and Wisconsin, the JLL report says.

Northern Virginia, the current data-center champ in the U.S., boasted a data-center market with 6,315 megawatts of capacity at the end of 2025, the report says. That compares with 2,423 megawatts in Dallas-Fort Worth, 1,700 megawatts in the Austin-San Antonio corridor, 200 megawatts in West Texas, and 164 megawatts in Houston.
