The Texas Exchange for Energy & Climate Entrepreneurship (TEX-E) has named Houston venture capital and innovation leader Sandy Guitar as its new executive director.

Guitar succeeds David Pruner, who will move into the board chair role.

Guitar previously served as general partner and managing director at Houston-based VC firm HX Venture Fund and is co-founder of Weathergage Capital. She also sits on the advisory board of Rice University's Liu Idea Lab for Innovation and Entrepreneurship (Lilie) and launched the Women Investing in VC in Houston group.

In a LinkedIn post, Guitar shared that she's looking forward to bringing her problem-solving skills to the energy transition.

"Innovating in the energy sector is as significant and intricate a problem as I have ever worked on — one that demands creativity, collaboration, and resourcefulness at every turn," she shared.

"I'm honored to join TEX-E at such a pivotal time in the energy transition," she added in a news release. "Energy and climate innovation is accelerating at the intersection of brilliant minds and bold ideas. I'm excited to help TEX-E amplify that collision between students who think differently and the real-world problems that demand fresh solutions."

According to TEX-E, Guitar will continue to lead the organization's programming that aims to connect student climate entrepreneurs with "industry reality."

"Sandy understands the complexities of the Texas energy ecosystem and brings a forward-looking vision for how related innovation can drive meaningful, lasting impact. She's exactly the leader we need to take TEX-E to the next level and help create the next generation of energy transition innovators," David Baldwin, TEX-E board member, added in the release.

TEX-E was founded in 2022 through partnerships with MIT Martin Trust Center for Entrepreneurship and Greentown Labs. It works with university students from six schools: Rice University, University of Houston, Prairie View A&M University, The University of Texas at Austin, Texas A&M University and MIT.

It's known for its student track within the Energy Venture Day and Pitch Competition at CERAWeek, which awarded $25,000 to HEXASpec, a Rice University-led team, at the 2025 event. It also hosted its inaugural TEX-E Conference, centered on the theme of Energy & Entrepreneurship: Navigating the Future of Climate Tech, earlier this year.

Why this organization is focused on cultivating the future of energy transition innovation

Q&A

David Pruner is laser focused on the future workforce for the energy industry as executive director of the Texas Entrepreneurship Exchange for Energy, known as TEX-E, a nonprofit housed out of Greentown Labs that was established to support energy transition innovation at Texas universities.

TEX-E launched in 2022 in collaboration with Greentown Labs, MIT’s Martin Trust Center for Entrepreneurship, and five university partners — Rice University, Texas A&M University, Prairie View A&M University, University of Houston, and The University of Texas at Austin.

Pruner was officially named to his role earlier this year, but he's been working behind the scenes for months now getting to know the organization and already expanding its opportunities from students across the state at the five institutions.

"Our mission is to create the next generation of energy transition climatetech entrepreneurs and intrapreneurs — they don’t all have to start companies," he says on the Houston Innovators Podcast.

Listen to the show below and read through a brief excerpt from the episode with Pruner.


EnergyCapital: Can you share a little bit about the origin of TEX-E?

David Puner: There were a variety of factories that led to its creation, but the seminal event was a piece of work that had been done for the Greater Houston Partnership by McKinsey on the future of Houston. It showed that if Houston isn't careful and doesn't make sure to go ahead and transition with this energy expansion we’re seeing, that they’re at risk of losing hundreds of thousands of jobs. If they catch the transition right and make the conversion to cleaner and low-carbon fuels, they can actually gain 1.4 million jobs.

It was this eye opener for everyone that we need to make sure that if the energy transition is going to happen, it needs to happen here so that Houston stays the energy capital of the world.

David Baldwin (partner at SCF Partners) literally at the meeting said, “listen I've got the beginning of the funnel — the universities, that’s where innovation comes from.” From that, TEX-E was born.

EC: How are you working with the five founding universities to connect the dots for collaboration?

DP: In the end, we have five different family members who need to be coordinated differently. The idea behind TEX-E is that there's plenty of bright students at each of these schools, and there's plenty of innovation going on, it's whether it can grow, prosper, and be sustainable.

Our main job is to look to connect everyone, so that an engineer at Texas A&M that has an idea that they want to pursue, but they don't know the business side, can meet that Rice MBA. Then, when they realize it's going to be a highly regulated product, we need a regulatory lawyer at UT — we can make all that happen and connect them.

At the same time, what we found is, no one school has the answer. But when you put them together, we do have most of the answer. Almost everything we need is within those five schools. And it's not just those five schools, it really is open to everyone.

EC: As you mentioned before, TEX-E started as a way for Houston to take the reins of its energy transition. What's the pulse on that progress?

DP: I spent the last decade building boards and hiring CEOs for all kinds of energy companies and there was the period I would say — pre-pandemic and a little bit into the pandemic — where not everybody was on board with climate change and the issue of carbon. The nice thing now is that’s fully in the rearview mirror. There’s not really a company of any size or a management team of any major entity that doesn’t fully believe they need to do something there.

The train has fully left the station — and picked up speed — on this whole issue of transition and climate. So, that’s been nice to see and create a lot of tailwinds.

Fervo Energy leads Time’s top green tech companies of 2026

top spot

The accolades keep coming for Houston-based geothermal energy company Fervo Energy.

Fervo sits atop Time magazine’s and Statista’s 2026 list of America’s Top GreenTech Companies. Fervo ranked No. 6 on the list last year.

The ranking honors 250 companies in the U.S. based on their environmental impact, innovation and financial strength. Fervo joins five other Houston-area companies on the list.

  • No. 49 Quaise Energy, an MIT Energy Initiative spinout that’s developing a drilling system designed to convert existing power stations for geothermal power production
  • No. 71 Plus Power, which develops, owns and operates battery energy storage systems
  • No. 98 Utility Global, whose technology enables industrial decarbonization
  • No. 199 Solugen, whose technology converts plant-based feedstocks into carbon-negative chemicals
  • No. 215 Noodoe, which specializes in EV charging stations and software

Fervo says its approach to enhanced geothermal systems (EGS)—including horizontal drilling, AI-enabled drilling and exploration, advanced reservoir engineering, and fiber-optic sensing—demonstrates how validated technology can help deliver reliable zero-emission power.

“By applying drilling technology from the oil and gas industry, we have proven that we can produce 24/7 carbon-free energy resources in new geographies across the world,” Fervo co-founder and CEO Tim Latimer said last year.

Other recent recognitions for Fervo includes:

  • The 2025 Houston Innovation Awards named it Scaleup of the Year
  • MIT Technology Review put Fervo on its 2025 list of the 10 global climatech companies to watch
  • Time named Fervo one of the 100 Most Influential Companies of 2025
  • Fervo was hailed as the Global Cleantech Group 100 North American Company of the Year
  • Fervo was among Congruent Ventures’ and Silicon Valley Bank’s 50 by 2050 companies, all of which are poised to advance global decarbonization over a 25-year span
Just last month, Fervo secured $421 million in debt financing for the construction of its 500-megawatt Cape Station geothermal project in Utah. And in December, the company landed an oversubscribed $462 million Series E round of funding, pushing its valuation to an estimated $1.4 billion. Fervo filed for an IPO earlier this year.

3 strategies to strengthen the Gulf Coast as a global energy hub

The View from HETI

The Texas-Louisiana Gulf Coast is the backbone of America’s energy and chemical economy. Texas produces roughly 43% of U.S. crude oil and 28% of natural gas, while Texas and Louisiana together account for about half of the nation’s refining capacity, processing 9.3 million barrels of crude per day across 50 refineries. The region also produces approximately 80% of the nation’s primary petrochemicals and ships more than $117 billion in chemical products annually from Texas alone.

This unmatched concentration of refining, petrochemical manufacturing, pipelines, ports, and technical talent makes the Gulf Coast one of the most critical energy hubs in the world. But maintaining that leadership in a rapidly evolving global market will require intentional collaboration, faster technology commercialization, and strengthened supply chain resilience.

In fall 2025, the Greater Houston Partnership’s Houston Energy Transition Initiative (HETI) convened national laboratories, Gulf Coast universities, and industry leaders to examine how to reinforce the region’s long-term competitiveness. Participants included Argonne, Oak Ridge, Lawrence Berkeley, the National Energy Technology Laboratory (NETL), and the National Laboratory of the Rockies, alongside Gulf Coast academic institutions and energy and chemical companies. Here are the key findings and takeaways from the workshop.

1. Supply Chain Resilience Requires Structured Industry–Lab Collaboration

Resilience—diversity of supply, operational flexibility, and rapid recovery—was a recurring theme. Recent disruptions exposed vulnerabilities in tightly interconnected energy and manufacturing systems.

National laboratories provide capabilities that complement Gulf Coast industrial scale, particularly at early and mid technology readiness levels (TRLs 1–7), before full commercial deployment. Examples include:

  • Advanced manufacturing and AI-enabled validation of critical components (Oak Ridge).
  • Materials scale-up and techno-economic modeling to move from lab discovery to industrial relevance (Argonne).
  • Pilot-scale testing for severe-service alloys, chemical conversion, and process innovation (NETL).
  • Integrated energy systems modeling to assess grid resilience and system disruptions (National Laboratory of the Rockies).

Recommendation: Organize targeted Gulf Coast industry missions to national laboratories focused on critical supply chains—power equipment, high-heat industrial processes, novel catalysts, refining, and grid infrastructure—to identify joint development opportunities and reduce time to commercialization.

2. Modeling, AI, and Open-Access Platforms Can Bridge the Technology Gap

A persistent barrier to innovation is the gap between scientific discovery, applied development, and commercial deployment. Universities often operate at TRLs 1–3, national labs at 1–7, and industry at 7–9. Bridging these silos requires shared modeling tools, high-performance computing, and structured feedback loops.

National labs maintain open-access platforms capable of:

  • Simulating grid expansion, investment, and dispatch decisions.
  • Modeling cradle-to-gate industrial material flows.
  • Optimizing complex energy and chemical systems.
  • De-risking carbon capture, critical mineral recovery, and advanced manufacturing integration.

Recommendation: HETI should convene structured training and feedback sessions on these public modeling platforms—ensuring Gulf Coast industry can apply, improve, and help guide further development of tools critical to regional competitiveness. Federal initiatives such as the Genesis Mission, focused on AI-accelerated scientific discovery, further expand opportunities for Gulf Coast participation.

3. Time to Commercialization Is the Ultimate Competitive Metric

The lithium-ion battery is a cautionary example: while pioneered in U.S. labs, large-scale manufacturing leadership shifted overseas. Without strategic intervention, U.S. firms are projected to capture less than 30% of domestic lithium battery cell value by 2030.

Successful DOE-backed consortium models show that mission-aligned, multi-partner collaboration reduces development timelines and strengthens domestic manufacturing know-how. However, public–private partnership mechanisms such as CRADAs and Strategic Partnership Projects can be time-intensive.

Recommendation: The Gulf Coast should actively engage DOE and national laboratories to streamline public–private partnership pathways, improve intellectual property clarity, and expand industry access to laboratory infrastructure.

The Path Forward: A Gulf Coast Consortium Model
The workshop’s central conclusion was clear: the Gulf Coast should formalize collaboration through a regional industry–academia–laboratory consortium.

Such a model could:

  • Co-locate national lab researchers within the region.
  • Share modeling data and analytical capabilities.
  • Establish open-access pilot facilities that complement lab infrastructure.
  • Harmonize IP frameworks to accelerate licensing and deployment.

With its dense industrial ecosystem, technical workforce, and decision-making concentration, the Gulf Coast is uniquely positioned to serve as a national demonstration hub for advanced energy and chemical manufacturing.

If industry, universities, and national laboratories align around a shared regional strategy, the Gulf Coast can:

  • Accelerate commercialization timelines.
  • Strengthen critical supply chains.
  • Unleash a world-class technical workforce.
  • Reinforce U.S. leadership in strategic energy and chemical sectors.
