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."

Addressing the need for collaboration in Houston's energy transition

Editor's note

When it comes to advancing the energy transition in Houston and beyond, experts seem to agree that collaborations between all major stakeholders is extremely important.

In fact, it was so important that it was the first panel of the second day of FUZE, an energy-focused conference put on by Digital Wildcatters. EnergyCapital HTX and InnovationMap were the event's media partners, and I, as editor of these news outlets, moderated the panel about collaborations.

I wanted to take a second to reflect on the conversation I had with the panelists earlier this week, as I believe their input and expertise — from corporate and nonprofit to startup and investing — was extremely valuable to the greater energy transition community.

Here were my three takeaways from the panel, titled "Collaborative Partnerships: Leveraging synergy in the energy sector."

Early-stage tech startups need bridges to cross their valleys.

The energy transition is a long game — and an expensive one, as Jane Stricker, executive director of the Houston Energy Transition Initiative, explains on the panel. And, just like most startups, the path to commercialization and profitability is long — and definitely not promised.

"When you look at innovation and startups, the multiple valleys of death a startup will go through on their journey, we have to find more ways to bridge those valleys and get more technology to get up that mountain and to a place where it can be scaled," she says.

She explains that corporations aren't always good at innovating, but they are impactful about rolling out de-risked technology at a global scale. But the technology has to get to that point first, so it takes a much earlier intervention for corporates — or another entity, like incubators and accelerators — to help in that developmental process.

"In Houston we have the potential to build out that ecosystem — we already have a lot of pieces in place, so it's about connecting the dots," Stricker says. "It's only by all of the different parts of the ecosystem understanding what each other does and what unique role they play in the process that we can really leverage the strengths of each of them to help create those partnerships and opportunities."

As Amy Henry, CEO of EUNIKE Ventures explains, corporates have their own challenges.

"Energy companies themselves have their own valley of death, and from where they are sitting, that's why they need to collaborate," she says on the panel. "And now we're talking about an unprecedented rate of getting technology commercialized."

EUNIKE works as a go between for corporates — almost as an expansion for them, Henry explains, and they are facing a challenging time too.

"Energy companies are just not early adopters of technology," she says. "But they are also going through their own transformation. At the same time, you've had this huge knowledge leakage in terms of all the workforce reduction."

Startups and corporates speak a different language.

Moji Karimi has had several partnerships with corporations with his biotech startup Cemvita Factory, including a recent offtake agreement with United. For Karimi, it's about learning about your corporate partner.

"In partnerships, especially for startups, you need to understand what is the language of love for the company at time," he says on the panel. "Is it growth, is it perception and PR, is it deployment of capital, or is there a specific bottleneck that we can help remove."

For HETI, Striker says they hope to act as a translator between the two parties.

"How do we enable more connectivity between the companies that have a technology that may be of interest to the larger companies looking for a solution?" Striker explains of HETI's mission. "And how do we make sure industry is communicating opening and broadly?"

Now is the time for action.

For Karimi, the solution is simple: More action is needed.

"Generally, we just need to talk less and do more," he says of what he wants to see from corporates, adding that more checks need to be written.

Based on his own experience, Karimi says some corporates are better to work with than others. He says he prefers working with the companies that don't try to mix in their startup pilots with the "bread and butter" of the business.

"Everyone has so much on their plate," he says, giving the example of Oxy Low Carbon Ventures being an offshoot of Oxy's main business.

Karimi says corporates should think of their startup pilots as an opportunity to try something new and different — something they'd never be able to test internally.

David Maher, business development director of Americas at Linde, says now that there's been regulatory framework, Linde knows what to invest in. The company has a particular interest in hydrogen.

"Another big piece of it is scale," Maher says of what Linde thinks about when considering innovative partnerships. "What's great about Houston is we have density and scale already."

United Airlines signs offtake arrangement with Houston startup for sustainable fuel production

green fuel incoming

An innovative Houston company is celebrating a new deal with a global airline.

Cemvita Corp. announced a new offtake arrangement with United Airlines. Cemvita's first full-scale sustainable aviation fuel plant will provide up to 1 billion gallons of SAF to United Airlines. The 20-year contract specifies that Cemvita will supply up to 50 million gallons annually to United.

It's not the first collaboration Cemvita has had with the airline. Last year, United invested in the biotech company, which used the funding to open its Houston pilot plant.

“Since our initial investment last year, Cemvita has made outstanding progress, including opening their new pilot plant – an important step towards producing sustainable aviation fuel,” United Airlines Ventures President Michael Leskinen says in a news release. “United is the global aviation leader in SAF production investment, but we face a real shortage of available fuel and producers. Cemvita’s technology represents a path forward for a potentially significant supply of SAF and it’s our hope that this offtake agreement for up to one billion gallons is just the beginning of our collaboration.”

Founded in Houston in 2017 by brother-sister team Moji and Tara Karimi, Cemvita's biotechnology can mimic the photosynthesis process, turning carbon dioxide into feedstock. The company's SAF plan hopes to increase reliability of existing SAFs and lower impact of fuel creation.

“Biology is capable of truly amazing things,” Moji Karimi, CEO of Cemvita, says in the release. “Our team of passionate, pioneering, and persistent scientists and engineers are on a mission to create sustainable BioSolutions that redefine possibilities.”

“We are thrilled to partner with United Airlines in working towards transforming the aviation industry and accelerating the energy transition,” he continues. “This agreement featuring our unique SAF platform is a major milestone towards demonstrating our journey to full commercialization.”

Earlier this year, United, which was reportedly the first airline to announce its goal of net zero carbon emissions by 2050, launched its UAV Sustainable Flight FundSM. The fund, which named Cemvita to its inaugural group of portfolio companies, has raised over $200 million, as of this summer.

Experts address Houston's energy transition role — from research to commercialization

HOUSTON @ SXSW

Every part of the energy industry is going to have a role in the energy transition — from the universities where the research and development is happening to the startups and the incumbent industry leaders, as a recent SXSW panel discussed.

“We are well known in Houston for being the energy capital of the world," Jane Stricker, executive director of the Houston Energy Transition Initiative, says as moderator of the panel. "The industry typically comes together with stakeholders to think about the solutions and how to solve this dual challenge of continuing to provide more energy to the world but doing it in a way that significantly reduces emissions at the same time.”

The panel, entitled "Ground Zero: Creating Pathways from Research to Scale Deployment," was put on by HETI, an organization under the Greater Houston Partnership, and took place Sunday, March 12, in Austin at SXSW.

“I often say that I believe Houston is ground zero for the transition because we have this unique combination of assets, infrastructure, innovation, research at universities, and a collective understanding of the importance of energy to people’s lives that allows us to tackle this problem in new ways," she continues.

Sticker was joined by Paul Cherukuri, vice president for innovation at Rice University; Juliana Garaizar, chief development and investment officer at Greentown Labs; and Tara Karimi, co-founder and CTO of Cemvita Factory. The panel highlighted the challenges facing Houston as it promises to lead the energy transition.

For Cherukuri, whose innovation-focused position was newly created when he was appointed to it last August, it's a pivotal moment for research institutions.

"It's really an exciting time in Houston because universities are changing," says Cherukuri. "Rice University itself is changing in dramatic ways, and it's a great opportunity to really plug into the energy transition inside of Houston."

The role he plays, as he explains, is to connect Rice innovators to the rest of the city and the world.

"We have to partner through the accelerators as well as with with companies who can catch what we've made and take it to scale," he continues. "That's uniquely something that we can do in Houston. It's not something that a lot of cities can do."

Representing the scaling efforts is Greentown Labs, and Garaizar explains how the Massachusetts-based organization, which has its second outpost in Houston, connects its member companies to corporate partners that can become funders, pilot partners, customers, and more. But scaling can only be accomplished with the right technologies and the proper funding behind them.

"Sixty percent of the technologies that are going to be used to decarbonize the world haven't yet been invented," she says on the panel. "So, there's a huge pull for technology right now. And we see people who are only on the private equity space now finally invested in a lot of earlier series like series A, but there's still some road to to be made there."

Houston-based Cemvita Factory is in the scale phase, and Karimi explains how she's actively working with companies to apply the company's unique biotechnology to convert CO2 to natural resources to accommodate each customer's needs. Cemvita is on the front lines of interacting with incumbent energy businesses that play a major role in the future of energy.

"The way we communicate with energy companies, we tell them that us to be the innovation arm for you and we work together," Karimi says. "I think it's everybody needs to understand it's a transition. There is no way to just change the way that chemicals are produced just immediately and replace it with something new. It's a transition that needs both aspects."

Expert: Why Texas must make energy transmission a top priority in 2026

guest column

Texas takes pride in running one of the most dynamic and deregulated energy markets in the world, but conversations about electricity rarely focus on what keeps it moving: transmission infrastructure.

As ERCOT projects unprecedented electricity demand growth and grid operators update their forecasts for 2026, it’s becoming increasingly clear that generation, whether renewable or fossil, is only part of the solution. Transmission buildout and sound governing policy now stand as the linchpin for reliability, cost containment, and long-term resilience in a grid under unprecedented stress.

At the heart of this urgency is one simple thing: demand. Over 2024 and 2025, ERCOT has been breaking records at a pace we haven’t seen before. From January through September of 2025 alone, electricity use jumped more than 5% over the year before, the fastest growth of any major U.S. grid. And it’s not slowing down.

The Energy Information Administration expects demand to climb another 14% in 2026, pushing total consumption to roughly 425 terawatt-hours in just the first nine months. That surge isn’t just about more people moving to Texas or running their homes differently; it’s being driven by massive industrial and technology loads that simply weren’t part of the equation ten years ago.

The most dramatic contributor to that rising demand is large-scale infrastructure such as data centers, cloud computing campuses, crypto mining facilities, and electrified industrial sectors. In the latest ERCOT planning update, more than 233 gigawatts of total “large load” interconnection requests were being tracked, an almost 300% jump over just a year earlier, with more than 70% of those requests tied to data centers.

Imagine hundreds of new power plants requesting to connect to the grid, all demanding uninterrupted power 24/7. That’s the scale of the transition Texas is facing, and it’s one of the major reasons transmission planning is no longer back-of-house policy talk but a central grid imperative.

Yet transmission is complicated, costly, and inherently long-lead. It takes three to six years to build new transmission infrastructure, compared with six to twelve months to add a new load or generation project.

This is where Texas will feel the most tension. Current infrastructure can add customers and power plants quickly, but the lines to connect them reliably take time, money, permitting, and political will.

To address these impending needs, ERCOT wrapped up its 2024 Regional Transmission Plan (RTP) at the end of last year, and the message was pretty clear: we’ve got work to do. The plan calls for 274 transmission projects and about 6,000 miles of new, rebuilt, or upgraded lines just to handle the growth coming our way and keep the lights on.

The plan also suggests upgrading to 765-kilovolt transmission lines, a big step beyond the standard 345-kV system. When you start talking about 765-kilovolt transmission lines, that’s a big leap from what Texas normally uses. Those lines are built to move a massive amount of power over long distances, but they’re expensive and complicated, so they’re only considered when planners expect demand to grow far beyond normal levels. Recommending them is a clear signal that incremental upgrades won’t be enough to keep up with where electricity demand is headed.

There’s a reason transmission is suddenly getting so much attention. ERCOT and just about every industry analyst watching Texas are projecting that electricity demand could climb as high as 218 gigawatts by 2031 if even a portion of the massive queue of large-load projects actually comes online. When you focus only on what’s likely to get built, the takeaway is the same: demand is going to stay well above anything we’ve seen before, driven largely by the steady expansion of data centers, cloud computing, and digital infrastructure across the state.

Ultimately, the decisions Texas makes on transmission investment and the policies that determine how those costs are allocated will shape whether 2026 and the years ahead bring greater stability or continued volatility to the grid. Thoughtful planning can support growth while protecting reliability and affordability, but falling short risks making volatility a lasting feature of Texas’s energy landscape.

Transmission Policy: The Other Half of the Equation

Infrastructure investment delivers results only when paired with policies that allow it to operate efficiently and at scale. Recognizing that markets alone won’t solve these challenges, Texas lawmakers and regulators have started creating guardrails.

For example, Senate Bill 6, now part of state law, aims to improve how large energy consumers are managed on the grid, including new rules for data center operations during emergencies and requirements around interconnection. Data centers may even be required to disconnect under extreme conditions to protect overall system reliability, a novel and necessary rule given their scale.

Similarly, House Bill 5066 changed how load forecasting occurs by requiring ERCOT to include utility-reported projections in its planning processes, ensuring transmission planning incorporates real-world expectations. These policy updates matter because grid planning isn’t just a technical checklist. It’s about making sure investment incentives, permitting decisions, and cost-sharing rules are aligned so Texas can grow its economy without putting unnecessary pressure on consumers.

Without thoughtful policy, we risk repeating past grid management mistakes. For example, if transmission projects are delayed or underfunded while new high-demand loads come online, we could see congestion worsen. If that happens, affordable electricity would be located farther from where it’s needed, limiting access to low-cost power for consumers and slowing overall economic growth. That’s especially critical in regions like Houston, where energy costs are already a hot topic for households and businesses alike.

A 2026 View: Strategy Over Shortage

As we look toward 2026, here are the transmission and policy trends that matter most:

Pipeline of Projects Must Stay on Track: ERCOT’s RTP is ambitious, and keeping those 274 projects, thousands of circuit miles, and next-generation 765-kV lines moving is crucial for reliability and cost containment.
Large Load Forecasting Must Be Nuanced: The explosion in large-load interconnection requests, whether or not every project materializes, signals demand pressure that transmission planners cannot ignore. Building lines ahead of realized demand is not wasteful planning; it’s insurance against cost and reliability breakdowns.
Policy Frameworks Must Evolve: Laws like SB 6 and HB 5066 are just the beginning. Texas needs transparent rules for cost allocation, interconnection standards, and emergency protocols that keep consumers protected while supporting innovation and economic growth.
Coordination Among Stakeholders Is Critical: Transmission doesn’t stop at one utility’s borders. Regional cooperation among utilities, ERCOT, and local stakeholders is essential to manage congestion and develop systemwide reliability solutions.

Here’s the bottom line: Generation gets the headlines, but transmission makes the grid work. Without a robust transmission buildout and thoughtful governance, even the most advanced generation mix that includes wind, solar, gas, and storage will struggle to deliver the reliability Texans expect at a price they can afford.

In 2026, Texas is not merely testing its grid’s capacity to produce power; it’s testing its ability to move that power where it’s needed most. How we rise to meet that challenge will define the next decade of energy in the Lone Star State.

New Gulf Coast recycling plant partners with first-of-kind circularity hub

now open

TALKE USA Inc., the Houston-area arm of German logistics company TALKE, officially opened its Recycling Support Center earlier this month.

Located next to the company's Houston-area headquarters, the plant will process post-consumer plastic materials, which will eventually be converted into recycling feedstock. Chambers County partially funded the plant.

“Our new recycling support center expands our overall commitment to sustainable growth, and now, the community’s plastics will be received here before they head out for recycling. This is a win for the residents of Chambers County," Richard Heath, CEO and president of TALKE USA, said in a news release.

“The opening of our recycling support facility offers a real alternative to past obstacles regarding the large amount of plastic products our local community disposes of. For our entire team, our customers, and the Mont Belvieu community, today marks a new beginning for effective, safe, and sustainable plastics recycling.”

The new plant will receive the post-consumer plastic and form it into bales. The materials will then be processed at Cyclyx's new Houston Circularity Center, a first-of-its-kind plastic waste sorting and processing facility being developed through a joint venture between Cyclix, ExxonMobil and LyondellBasell.

“Materials collected at this facility aren’t just easy-to-recycle items like water bottles and milk jugs. All plastics are accepted, including multi-layered films—like chip bags and juice pouches. This means more of the everyday plastics used in the Chambers County community can be captured and kept out of landfills,” Leslie Hushka, chief impact officer at Cyclyx, added in a LinkedIn post.

Cyclyx's circularity center is currently under construction and is expected to produce 300 million pounds of custom-formulated feedstock annually.
