Fort Worth-based American Airlines has sealed a record-breaking deal with tech giant Google to bolster the use of cleaner jet fuel.

The deal involves Google’s purchase of sustainable aviation fuel certificates tied to fuel that American will use at Chicago O’Hare International Airport, one of the airline’s hubs. These certificates enable companies like Google to pay for the environmental benefits of sustainable jet fuel without actually using the fuel.

American and Google say this is the largest publicly announced certificate deal between an airline and a corporate customer.

Google says environmental gains from the certificates will help it cut emissions from employees’ business travel.

The agreement covers 35 million gallons of sustainable aviation fuel over three years, resulting in a nearly 300,000 metric tons of carbon dioxide equivalent emissions. American has agreed to buy the fuel from San Antonio-based Valero.

“Our industry-leading agreement with Google is a critical step forward in reducing emissions from our operations,” Jill Blickstein, American’s chief sustainability officer, said in a news release. “By working with leaders like Google who share our commitment to innovation, we’re helping to grow demand for [cleaner jet fuel] and support the development of a stronger, more resilient market.”

Sustainable aviation fuel can reduce emissions by up to 80 percent compared with traditional jet fuel. It is made from feedstocks, like waste oil and fats, or it can be produced synthetically using captured carbon dioxide and renewable electricity.

The aviation industry accounts for about 2.5 percent of carbon dioxide emissions around the world, according to the International Energy Agency.

Cemvita reaches breakthrough in sustainable fuel feedstock production

clean fuels

The company shared in a news release that it completed a 75,000-liter industrial fermentation run at Belgium's Bio Base Europe Pilot Plant.

The campaign achieved target technical metrics for the production of FermOil, Cemvita’s renewable natural oil (RNO). FermOil is produced from industrial crude glycerin, an industrial byproduct, as opposed to traditional sugar-based feedstocks used in many bio-oil fermentation processes. It's designed to be a drop-in feedstock for creating SAFs.

Cemvita had previously advanced its FermOil production process through multiple scale-up stages before successfully reaching the 75,000-liter demonstration campaign, according to the company.

“This is not just a fermentation milestone,” Moji Karimi, CEO at Cemvita, said in the release. “It is a blueprint for how existing industrial infrastructure can evolve into circular bioeconomy infrastructure. Every biodiesel plant generating crude glycerin is a potential platform for renewable natural oil production.”

The milestone also supports the deployment of Cemvita’s industrial biomanufacturing platform, FermWorks, which integrates with existing energy and industrial infrastructure to turn waste carbon streams into SAFs and other materials. According to the release, Cemvita plans to move forward with commercial deployment discussions with partners in Brazil, Europe and in the UK. Cemvita already has a partnership with the Brazilian sustainable research institution REMA.

“We are proud to support innovative companies like Cemvita in scaling breakthrough industrial biotechnology solutions,” Hendrik Waegeman, head of business operations at Bio Base Europe Pilot Plant, added in the release. “Successfully operating at the 75,000-liter scale using a feedstock such as crude glycerin highlights both the maturity of the technology and the quality of the scale-up execution achieved by the Cemvita team.”

fuel deal

Houston-based Syzygy Plasmonics has secured a six-year official offtake agreement for the entire production volume of its first commercial-scale biogas-to-sustainable aviation fuel project in Uruguay, known as NovaSAF-1.

SP Developments Uruguay S.A., a subsidiary of Syzygy, entered into the agreement with Singapore-based commodity company Trafigura, according to a news release. There is also an option for Trafigura to purchase additional volumes from future Syzygy projects.

The first deliveries from the landmark SAF facility are expected in 2028.

“This agreement marks a critical step in our journey toward commercial-scale impact and disrupting the SAF market,” Trevor Best, CEO of Syzygy Plasmonics, said in the news release. “With a signed offtake agreement from a global leader like Trafigura, and after having successfully completed FEED engineering in December, we're now ready to secure financing for the construction of NovaSAF-1 and move our technology from potential into production."

The NovaSAF-1 project will be located in Durazno, Uruguay. The facility will be the world's first electrified biogas-to-SAF facility producing renewable and advanced compliant SAF. Syzygy estimates that the project will produce over 350,000 gallons of SAF annually. The facility is expected to produce SAF with at least an 80 percent reduction in carbon intensity compared to Jet A fuel.

It’s backed by Uruguay’s largest dairy and agri-energy operations, Estancias del Lago. It will also work with Houston-based Velocys, which will provide Fischer-Tropsch technology for the project. Fischer-Tropsch technology converts synthesis gas into liquid hydrocarbons, which is key for producing synthetic fuels like SAF.

Syzygy unveils plans for groundbreaking sustainable aviation fuel facility

coming soon

Houston-based Syzygy Plasmonics announced plans to develop what it calls the world's first electrified facility to convert biogas into sustainable aviation fuel (SAF).

The facility, known as NovaSAF 1, will be located in Durazno, Uruguay. It is expected to produce over 350,000 gallons of SAF annually, which would be considered “a breakthrough in cost-effective, scalable clean fuel,” according to the company.

"This is more than just a SAF plant; it's a new model for biogas economics," Trevor Best, CEO of Syzygy Plasmonics, said in a news release. "We're unlocking a global asset class of underutilized biogas sites and turning them into high-value clean fuel hubs without pipelines, costly gas separation, or subsidy dependence.”

The project is backed by long-term feedstock and site agreements with one of Uruguay's largest dairy and agri-energy operations, Estancias del Lago, while the permitting and equipment sourcing are ongoing alongside front-end engineering work led by Kent.

Syzygy says the project will result in a 50 percent higher SAF yield than conventional thermal biogas reforming pathways and will utilize both methane and CO2 naturally found in biogas as feedstocks, eliminating the need for expensive CO2 separation technologies and infrastructure. Additionally, the modular facility will be designed for easy replication in biogas-rich regions.

The new facility is expected to begin commercial operations in Q1 2027 and produce SAF with at least an 80 percent reduction in carbon intensity compared to Jet A fuel. The company says that once fully commercialized the facility will produce SAF at Jet-A fuel cost parity.

“We believe NovaSAF represents one of the few viable pathways to producing SAF at jet parity and successfully decarbonizing air travel,” Best added in the release.

eyes on SAF

Houston developer of ultra carbon-negative fuels projects Pathway Energy announced a series of commercial-scale sustainable aviation fuel (SAF) facilities with the first being based in Port Arthur, Texas.

The project, estimated to be valued at $2 billion, will be one of the largest decarbonization projects in the world.

Pathway plans to bring commercial SAF to market with its years of experience in waste and biomass conversion processes and technologies that include biomass gasification, Fischer-Tropsch, biomass power generation, and complex biorefinery and industrial processes. Pathway will be working with companies like Sumitomo SHI FW, who will supply the project with gasification process technology packages and power production. Pathway Energy also announced a strategic partnership with Drax Global, which is a biomass feedstock provider.

"We are happy to debut with the best technology and industrial partners in the industry on a market opportunity with global significance," Steve Roberts, CEO of Pathway Energy, says in a news release. "With the ultra negative carbon intensity achieved through our process, Pathway Energy is poised to lead a global market for ultra negative fuels, driving large scale emission reductions across the aviation sector."

In the Port Arthur project, Pathway plans to leverage sustainable biomass feedstock and access to geological storage to sequester carbon and to produce its ultra carbon-negative SAF. The site location already is equipped with industrial scale import and export logistics including established truck, rail, barge, and pipeline access. Pathway will develop a platform of commercial-scale facilities in areas with a high potential for geological storage to utilize BECCS (Biomass Energy Carbon Capture and Storage) and gasification technology to capture and store carbon, according to a news release.

The market for sustainable aviation fuel uses imported, used cooking oil (UCO HEFA). UCO HEFA SAF can’t materially decarbonize aviation since its constrained supply and positive carbon intensity score. Pathway’s ultra carbon-negative fuel is synthetic drop-in jet fuel that achieves a 550% reduction of carbon compared to traditional jet fuel, which is an industry first. Pathway believes this can abate as much as 6,000 flights a year.

Pathway uses an ultra-negative SAF, which carriers require less SAF to achieve emissions reduction as HEFA, which translates to emissions reduction, and lower cost of operations. The aviation industry can potentially achieve up to 8 times more emissions reductions compared to HEFA SAF.

“We saw the opportunity to provide carriers a pathway to completely decarbonize their flights with our net zero blended fuel," Joshua Pearson, Pathway CTO, adds. "This is a new type of SAF production that is 7-9 (times) more carbon negative than the SAF on the market today and represents the most sustainable, cost efficient and de-risked path to decarbonize global aviation.”

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 promotes strategy leader to COO as flagship geothermal project nears launch

new leader

Houston geothermal unicorn Fervo Energy has named Sarah Jewett as its new COO.

Jewett steps into the role as the company prepares for its flagship Cape Station geothermal project to deliver its first power later this year.

Jewett joined Fervo in 2020 as director of strategy and most recently served as the company's senior vice president of strategy. She spoke with HETI on the potential of geothermal energy in 2024.

Before Fervo, Jewett served as senior director of corporate development for Houston-based Select Energy Services. She ran hydraulic fracturing crews for Schlumberger in the Permian Basin and Alaska's North Slope early in her career.

In the COO role, Jewett is tasked with creating "the centralized infrastructure required to execute on what the company believes is the most significant commercial opportunity for clean, firm power in history," according to a company release.

“What Sarah has built over the last six years has been foundational to the company’s success. From the time she joined, she has brought an unwavering people-first mindset and outstanding dedication to building things that last,” Tim Latimer, CEO and co-founder of Fervo, added in the release. “As we move into the next phase of our growth, there is no better person to lead the operating core of this company.”

Jewett holds an MBA from Harvard Business School and a bachelor's degree in mechanical engineering from Dartmouth College.

Fervo announced the addition of four heavyweights to its board of directors this spring, including Meg Whitman, former CEO of eBay, Hewlett-Packard, and Spring-based HPE. Shortly after, the company filed for its highly anticipated $1 billion-plus IPO. Read more here.

UH study finds Gulf Coast best positioned for emerging carbon removal technology

coastal impact

The Gulf Coast is an ideal spot for deploying a new ocean-based carbon removal technology that uses seawater to capture and store carbon dioxide, according to a new study from the University of Houston.

The study was led by UH Cullen College of Engineering Professor Mim Rahimi and published in Nature’s Communications Sustainability journal. Abdelrahman Refaie, a PhD student at UH, authored the paper. It aimed to develop a plan for implementing an electrochemical marine carbon dioxide removal (e-mCDR) technology that treats seawater to increase the ocean’s ability to absorb and store carbon dioxide from the air.

Currently, oceans absorb about 30 percent of human-produced carbon dioxide emissions each year, according to UH, making it a great natural resource for carbon removal.

The team at UH scouted and analyzed 38 coastal facilities across the U.S.—including power plants, desalination plants, and liquefied natural gas (LNG) terminals—before determining the Gulf Coast as an attractive option. The South Hub, or the Gulf Coast along Texas and Louisiana, ranked the top-performing area for the technology due to the industrial infrastructure, affordable electricity, hydrogen transportation and storage networks.

Other regions like California and the Northeast also scored well due to their clean energy mix and carbon removal potential, according to UH.

“The South hub has one of the highest diversity factors between power plants, desalination and LNG,” Refaie said in a news release. “That means if, logistically, down the road LNG is not open for this implementation, then we have another option in the area. It reduces the risk factor.”

UH says the findings show how companies could commercialize the technology, which could boost coastal economies.

“The question we had wasn’t technical, rather, it was logistical in regard to implementation down the road,” Rahimi said. “This would be a roadmap if a company or the government wants to utilize this technology.”

Rahimi aims to increase awareness about e-mCDR technology and its potential impact. He recently discussed the ocean-centric carbon removal work with members of Congress in March at the Carbon to Sea’s 2026 Hill Day.

“I think faculty at the University of Houston can do more of this kind of work,” Rahimi said in a separate release. “Meeting with Members of Congress gives us a chance to help policymakers better understand the science and engineering happening at our university. That kind of engagement is an important part of moving new technologies forward. It also shows how the work we do on campus can have a real impact on communities beyond the university.”
