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.

Annual Houston conference to target topics on digitalization of decarbonization

thought leadership

An event that brings top venture capitalists to Houston returns for its third year — and this time the topic of conversation is the energy transition.

Venture Houston, taking place on September 7, is presented by HX Venture Fund, a fund of funds that deploys capital into non-Houston firms to encourage investment in local startups. This year's theme is "Spotlighting the path for decarbonization in a digital world," and Sandy Guitar, managing partner at HXVF, tells EnergyCapital that while that might sound like a narrow topic, attendees will see at the event how broad a theme it really is.

"We're calling it digitalization to decarbonization in order to help identify the fact that decarbonization is just a market that you sell into — the technologies are very broadly defined," Guitar says. "Underneath that, the decarbonization market happens to involve everything that is better, cheaper, and faster."

The event, which has its ticket registration open now, has a full agenda with several keynote addresses and panels featuring venture leaders, CEOs, startup founders, and more from Houston and beyond. There will also be networking breaks and other activations, including a breakfast presented by DivInc and Capital Connect on September 6. This event features curated collisions for a select VCs and founders.

The conference's first panel, "Seeding Sustainability: Unlocking the Power of Early Stage Investments," includes Josh Posamentier, co-founder and managing partner of Congruent Ventures, who will share the stage with the founder of one of his firm's portfolio companies, Tim Latimer of Fervo Energy, among others.

To Posamentier, one of the things he hopes attendees takes away is how timely decarbonization is — especially in Houston.

"If I had one ask, it would be that people, especially for this audience, double down and mobilize more toward alternative energy," he tells EnergyCapital. "Take all the learnings, all the skills that come from conventional energy and repurpose them. I think there's it's a bigger market — more is being spent on renewables now than on oil and gas development and, you've got got a good 50 years of insane growth ahead."

And, as Guitar adds, the energy transition is not something that only affects the companies building the technology or working within the energy industry.

"I do think it's important to see the decarbonization not as a hard tech event, but as everything that touches carbon, which is basically everything in our planet in just the coal previously," she says. "Everything we make and use touches the climate."

ExxonMobil expands Gulf Coast CCS business with Louisiana deal

carbon contract

Spring-based energy powerhouse ExxonMobil has picked up another project in the carbon capture and storage (CCS) market.

Natural gas pipeline operator Williams Cos. has tapped ExxonMobil to transport and store up to one metric ton per year of CO2 from Williams’ natural gas collection and processing plant in southwest Louisiana’s Haynesville Shale.

Williams will transport natural gas via its Louisiana Energy Gateway pipeline, then process the natural gas and deliver it to the Gulf Coast for export as liquefied natural gas (LNG). The LNG will be used in power generation, residential and commercial heating, and industrial processes.

Williams recently agreed to acquire Momentum Midstream for up to $5.5 billion to expand Williams’ LNG presence in the Haynesville Shale. Haynesville is the country’s third-largest producer of natural gas.

Once the deal closes, Williams will own a $1.5 billion project in southwest Louisiana that will expand capacity of the Transco natural gas distribution system. The system serves power and LNG-export customers. Williams will also gain over 4,000 miles of pipeline and more than one million acres.

While Williams is based in Tulsa, Oklahoma, it has a significant presence in Houston. Last month, Green Street’s Real Estate Alert reported Williams bought the 64-story, 1.4 million-square-foot Williams Tower south of The Galleria from Invesco Real Estate for more than $300 million. The company will occupy about 360,000 square feet in the skyscraper for its Houston hub.

Williams employs about 800 people in Bayou City, including roughly 700 who work at Williams Tower, and plans to hire another 100 by the end of this year.

The Williams deal is ExxonMobil’s seventh CCS contract. ExxonMobil’s CCS portfolio supports LNG, lower-carbon-intensity steel, ammonia, natural gas processing, industrial gases and methanol.

ExxonMobil has established a “carbon superhighway” along the Gulf Coast to fuel its CCS business. The company owns and operates a more than 1,300-mile CO2 pipeline system, the largest in the U.S.

“Carbon capture is becoming an increasingly important part of industrial operations, but capture alone doesn’t solve the problem of high emissions,” says ExxonMobil. “What matters next is how CO2 is transported, used, and stored.”

ExxonMobil’s CCS initiatives are aimed at capturing a chunk of the rapidly growing CCS market in the U.S. Straits Research forecasts the market will grow from $5.66 billion this year to $13.56 billion by 2034.

“It’s not every day you get to witness the birth of a new American industry, but that’s exactly what’s happening right now at the U.S. Gulf Coast,” Dominic Genetti, senior vice president of CCS at ExxonMobil, wrote in an article published last year on the company’s website.

Fervo Energy, Mercury Fund leaders named first experts in residence for TEX-E

energy mentors

Two leading companies in Houston's clean energy scene have been named the Texas Exchange for Energy & Climate Entrepreneurship's first experts in residence.

TEX-E announced this month that Houston-based geothermal unicorn Fervo Energy and venture capital firm Mercury Fund have joined the nonprofit's new Expert-in-Residence partnership. The program aims to connect TEX-E Fellows with "the people and organizations shaping the future of energy and entrepreneurship."

The 2026 TEX-E Fellows were named in June and include 67 students from six Texas universities and the Massachusetts Institute of Technology. Nineteen are from Houston universities. See the full list here.

Through the Expert-in-Residence program, fellows will be able to network and work with:

"More than anything, students need the determination and creativity to step outside of their comfort zones and tackle problems that lack clear answers. At Fervo, we've consistently bet on young people who lack traditional 'hard skills' but are willing to embrace uncertainty and learn on the job. That open-mindedness will take students far," Jewett said in a prepared statement. Fervo named Jewett as COO in June.

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.

The organization named Houston venture capital and innovation leader Sandy Guitar as its new executive director last year. Guitar previously served as general partner and managing director at Houston-based VC firm HX Venture Fund and is co-founder of Weathergage Capital.

TEX-E is known for its student track within the Energy Venture Day and Pitch Competition at CERAWeek. It awarded $50,000 to student teams from the University of Texas and Rice University. Read more here.

BP to sell Houston’s Archaea Energy after $4.1 billion bet on biogas

RNG exit

Oil and gas conglomerate BP is unloading its Houston-based U.S. renewable natural gas business just four years after buying it.

The British company announced the planned sale of Archaea during its most recent earnings call but offered few details.

On the call, BP’s new CEO, Meg O’Neill, said her company had put Archaea on the market and already had attracted interest from potential buyers. BP acquired Houston-based Archaea Energy, the country’s largest producer of renewable natural gas (RNG), in 2022 for about $4.1 billion.

BP, whose North American headquarters is in Houston, is streamlining its portfolio. As such, O’Neill said Archaea represents a “capital intense” approach to biogas instead of the “capital light” approach BP now favors.

“If there’s somebody who sees an opportunity to create additional value, who will invest in that business, who will build on the foundation, because our team has made really good progress in improving the profitability of that business, then that will be a good outcome,” O’Neill told Wall Street analysts.

The proposed sale of Archaea is part of BP’s effort to sell about $20 billion in assets by the end of next year.

Archaea captures biogas, a natural byproduct of waste decomposition at landfills and dairy farms, and converts it into electricity or RNG. This process leads to cleaner air, less odor, and more sustainable energy than traditional fossil fuels.

Archaea was slated to be a cornerstone of BP’s plan to boost its biogas supply by roughly 600 percent to the equivalent of about 70,000 barrels of oil per day.

Bioenergy had been identified as one of bp’s five pillars of its multibillion-dollar energy transition initiative.

Another pillar: EV charging. Last month, BP agreed to sell its EV charging business in Austria to Switzerland’s Volenergy, along with 250 BP-branded stores and a fleet of business vehicles.

“By concentrating our capital on the assets and markets where BP can be most competitive and best serve customers, we are strengthening our balance sheet and creating a stronger downstream portfolio,” Richard Harding, interim executive vice president of downstream at BP, said of the Volenergy deal.
