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."

Fervo Energy officially files for initial public offering

going public

Fervo Energy has officially filed for IPO.

The Houston-based geothermal unicorn filed a registration statement on Form S-1 with the U.S. Securities and Exchange Commission on April 17 to list its Class A common stock on the Nasdaq exchange. Fervo intends to be listed under the ticker symbol "FRVO."

The number and price of the shares have not yet been determined, according to a news release from Fervo. J.P. Morgan, BofA Securities, RBC Capital Markets and Barclays are leading the offering.

The highly anticipated filing comes as Fervo readies its flagship Cape Station geothermal project to deliver its first power later this year

"Today, miles-long lines for gasoline have been replaced by lines for electricity. Tech companies compete for megawatts to claim AI market share. Manufacturers jockey for power to strengthen American industry. Utilities demand clean, firm electricity to stabilize the grid," Fervo CEO Tim Latimer shared in the filing. "Fervo is prepared to serve all of these customers. Not with complex, idiosyncratic projects but with a simplified, standardized product capable of delivering around-the-clock, carbon-free power using proven oil and gas technology."

Fervo has been preparing to file for IPO for months. Axios Pro first reported that the company "quietly" filed for an IPO in January and estimated it would be valued between $2 billion and $3 billion.

Fervo also closed $421 million in non-recourse debt financing for the first phase of Cape Station last month and raised a $462 million Series E in December. The company also announced the addition of four heavyweights to its board of directors last week, including Meg Whitman, former CEO of eBay, Hewlett-Packard, and Spring-based HPE.

Fervo reported a net loss of $70.5 million for the 2025 fiscal year in the S-1 filing and a loss of $41.1 million in 2024.

Tracxn.com estimates that Fervo has raised $1.12 billion over 12 funding rounds. The company was founded in 2017 by Latimer and CTO Jack Norbeck.

Houston lawmaker may kill data center tax breaks due to $8B revenue loss

looking at the data

An influential Houston-area state senator is raising concerns about potentially billions of dollars in lost state revenue from tax breaks for Texas data centers—and is pondering legislation that would abolish the tax incentives.

Citing data from the state comptroller’s office, The Texas Tribune reports the state stands to lose nearly $8 billion in revenue from 2026 to 2030 due to sales tax and use tax exemptions for data centers. During the state’s 2025 fiscal year, which ended on Aug. 31, these tax exemptions caused Texas to lose a little over $1 billion, up from an earlier estimate of $130 million.

“These new numbers are extremely concerning, and I will say they’re unsustainable,” Republican state Sen. Joan Huffman, chairwoman of the state Senate Finance Committee, tells The Texas Tribune. “I plan to look at filing legislation to either repeal the exemption or take a very close look at it and see.”

Texas on track to be No. 1 data center market in U.S.

Scrutiny of the tax breaks comes amid an explosion of data center development in Texas, where data provider Aterio identifies nearly 1,000 centers that are operating, under construction or planned.

A report issued in January by Bloom Energy says the state is poised to become the No. 1 U.S. market for data centers within three years. By 2028, according to the report, Texas is projected to exceed 40 gigawatts of data center capacity—representing nearly 30 percent of total U.S. demand.

Among companies benefiting from the data center boom are:

  • Tech titans like Apple, Google, Meta Platforms, and Microsoft, which are spending billions of dollars to build data centers in Texas.
  • Spring-based ExxonMobil and Houston-based Chevron, two oil and energy giants that are developing natural gas plants to supply power for data centers.
  • Houston-based energy technology company Baker Hughes, which is collaborating with Google Cloud to develop AI-enabled power optimization and sustainability software for data centers.
  • DataBank, Data Foundry, Equinix, Digital Realty, Lumen Technologies, and IBM, all of which operate data centers in the Houston area.

The Texas Legislature will begin debating tax breaks for data centers in July, when Huffman’s Senate Finance Committee meets for an interim hearing before the 2027 legislative session, according to the Tribune.

Data center industry defends tax breaks

Leaders in the data center industry warn that watering down or halting the tax breaks could slow down or even end Texas’ ascent in the data center sector.

A 2025 report commissioned by the Data Center Coalition found that in 2024, data centers provided more than $1.6 billion in state tax revenue and almost $1.6 billion in local tax revenue in Texas. Over the next several years, according to the report, planned development of data centers in the Lone Star State could generate almost $3.8 billion in state tax revenue and more than $4.9 billion in local tax revenue.

In 2024, the Houston area had 8.1 million gross square feet of data centers, with the properties’ real estate investments sitting at $10 billion, according to the report. That year, data centers in the region produced a little over $700 million in state and local tax revenue. About 60 data centers operate in the Houston area.

Watchdog group warns of tax breaks’ danger to state budgets

On the other side of the debate over tax breaks for data centers, a report released last year by Good Jobs First, a nonprofit, nonpartisan watchdog group that tracks economic development incentives, decries the tax breaks as dangerous to state budgets.

“We know of no other form of state spending that is so out of control. Therefore, we recommend that states cancel their data center tax exemptions,” says Good Jobs research analyst Kasia Tarczynska, co-author of the report. “Shy of that, states should amend … legislation to cap how much any facility and company can avoid paying in taxes each year.”
