Three Houston executives — Andrew Chang, Tim Latimer, and Cindy Taff — have been named to Time magazine’s prestigious list of the 100 Most Influential Climate Leaders in Business for 2024.

As managing director of United Airlines Ventures, Chang is striving to reduce the airline’s emissions by promoting the use of sustainable aviation fuel (SAF). Jets contribute to about two percent of global emissions, according to the International Energy Agency.

In 2023, Chang guided the launch of the Sustainable Flight Fund, which invests in climate-enhancing innovations for the airline sector. The fund aims to boost production of SAF and make it an affordable alternative fuel, Time says.

Chang tells Time that he’d like to see passage of climate legislation that would elevate the renewable energy sector.

“One of the most crucial legislative actions we could see in the next year is a focus on faster permitting processes for renewable energy projects,” Chang says. “This, coupled with speeding up the interconnection queue for renewable assets, would significantly reduce the time it takes for clean energy to come online.”

At Fervo Energy, Latimer, who’s co-founder and CEO, is leading efforts to make geothermal power “a viable alternative to fossil fuels,” says Time.

Fervo recently received government approval for a geothermal power project in Utah that the company indicates could power two million homes. In addition, Fervo has teamed up with Google to power the tech giant’s energy-gobbling data centers.

In an interview with Time, Latimer echoes Chang in expressing a need for reforms in the clean energy industry.

“Addressing climate change is going to require us to build an unprecedented amount of infrastructure so we can replace the current fossil fuel-dominated systems with cleaner solutions,” says Latimer. “Right now, many of the solutions we need are stalled out by a convoluted permitting and regulatory system that doesn’t prioritize clean infrastructure.”

Taff, CEO of geothermal energy provider Sage Geosystems, oversees her company’s work to connect what could be the world’s first geopressured geothermal storage to the electric grid, according to Time. In August, Sage announced a deal with Facebook owner Meta to produce 150 megawatts of geothermal energy for the tech company’s data centers.

Asked which climate solution, other than geothermal, deserves more attention or funding, Taff cites pumped storage hydropower.

“While lithium-ion batteries get a lot of the spotlight, pumped storage hydropower offers long-duration energy storage that can provide stability to the grid for days, not just hours,” Taff tells Time. “By storing excess energy during times of low demand and releasing it when renewables like solar and wind are not producing, it can play a critical role in balancing the intermittent nature of renewables. Investing in pumped storage hydropower infrastructure could be a game-changer in achieving a reliable, clean energy future.”

How United Airlines got into the sustainable energy biz

funding SAF

While someone might not immediately make the connection between aviation and the energy transition, United Airlines understands the importance of more sustainable fuel — and has put its money where its mouth is.

According to an International Energy Agency report, the aviation accounted for 2 percent of global energy-related CO2 emissions last year. Earlier this year, United Airlines launched a fund that called for collaboration across the industry.

After only five months, the United Airlines Ventures Sustainable Flight Fund SM increased to nearly $200 million and added new financial partners, airlines, and more. The fund takes on funding from its 13 limited partners and exists separately from United's core business operations.

Andrew Chang, managing director of United Airlines Ventures, says it's his job to accelerate the airline's mission to decarbonize operations. He explains that working together on the fund is the key for advancing sustainable aviation fuel, or SAF.

"We all recognize that we may compete in our core business, but with the importance of sustainable aviation fuel and given that it's an industry that doesn't exist — you can't compete for something that doesn't exist — let's collaborate and work together to explore technologies that can directly or indirectly support the commercialization and production of sustainable aviation fuel," he says on the Houston Innovators Podcast.

United Airlines also recently signed an offtake agreement with Cemvita Factory, a Houston biotech startup that's working on SAF. Chang discusses this partnership on the show, as well as explaining how he works with other startups and what he's looking for.

The offtake agreement and the fund are just two examples of how United is building to a more sustainable future. As Chang explains on the show, the aviation industry hasn't evolved too much over the past three or four decades.

"It's been a challenging market," he says, blaming the ever-evolving macroeconomic conditions for providing challenges for the airline, taking away its focus from new technologies. "But I think we are at a point where the industry is in a healthier place, the sector has consolidated, we are supported by our consumers, and we are now empowered with the financial and strategic capital to think ahead."

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.
