Naomi Halas, a Rice University professor and co-founder of Syzygy Plasmonics, was elected to the Council of the National Academy of Sciences this month.

The council sets priorities for the nonprofit organization, which advises the federal government on scientific and technical matters. Halas will serve a three-year term on the council, beginning July 1.

“The council’s work is focused on the academy’s national leadership and governance,” Halas said in a news release. “It plays an important role in helping set initiatives and priorities for the scientific community, and in supporting the conditions that allow science to move forward in meaningful ways.”

Halas is best known for her pioneering work in nanophotonics and plasmonics. She helped develop nanoshells, or metal-coated nanoparticles that capture light energy, which have led to innovations in renewable energy, cancer therapy and water purification.

Halas co-founded Syzygy Plasmonics with frequent collaborator and fellow Rice professor Peter Nordlander. The company is developing low-cost, light-driven, all-electric chemical reactors for the sustainable production of hydrogen fuel. It was named to Fast Company's energy innovation list last year.

Syzygy Plasmonics is developing its first commercial-scale biogas-to-sustainable aviation fuel project in Uruguay, known as NovaSAF-1. It secured a six-year offtake agreement for the entire production from the project with Singapore-based commodity company Trafigura this month.

Halas was first elected to become a member of the NAS in 2013, and was shortly after named to the National Academy of Engineering in 2014—making her one of the few scientists to hold both distinctions. She received the Benjamin Franklin Medal in Chemistry last year. Many scientists who have received the award have gone on to win Nobel prizes.

She is also the co-founder of Nanospectra Biosciences and a member of the National Academy of Inventors, the American Academy of Arts and Sciences, and the Royal Danish Academy of Science and Letters. She holds more than 25 patents, according to Rice.

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.

3 Houston-area companies named to Global Cleantech 100

Energized

Three Houston-area companies—Amperon, Hertha Metals and Vaulted Deep—appear on this year’s Global Cleantech 100 list.

The unranked list, generated by market intelligence and advisory firm Cleantech Group, identifies the 100 privately held companies around the world that are most likely to make a significant impact in the cleantech market over the next five to 10 years.

For the 2026 list, Cleantech Group received more than 24,000 Global Cleantech 100 nominations from nearly 60 countries. Cleantech Group scored those companies and narrowed the contenders to 264. An expert panel reviewed those nominees, and the list was whittled down to the 100 winners.

Here’s a rundown of the three Houston-area honorees:

Amperon

Founded in 2018 by Sean Kelly and Abe Stanway, Houston-based Amperon offers an AI-enabled energy forecasting and analytics platform designed to help stabilize electric grids. Amperon received undisclosed amounts of venture capital from National Grid Partners and Tokyo Gas Co. Ltd. last year and announced a recent investment from Samsung Ventures earlier this month.

Hertha Metals

Founded in 2022 by Laureen Meroueh, Conroe-based Hertha Metals provides a single-step process for producing sustainable steel. Last year, the company emerged from stealth mode and raised more than $17 million in venture capital.

Vaulted Deep

Vaulted Deep’s technology injects excess organic waste underground to remove carbon dioxide from the atmosphere. Julia Reichelstein and Omar Abou-Sayed founded the Houston-based company in 2023. Last year, the startup raised $32.3 million in venture capital. Also in 2025, Vaulted Deep signed a 12-year deal with software giant Microsoft to remove up to 4.9 million metric tons of carbon dioxide from the environment.

Vaulted Deep also made the list last year, along with Houston-based Syzygy Plasmonics and Fervo Energy. Fervo was also named the 2025 North American Company of the Year by Cleantech Group.

SAF production

Houston-based Syzygy Plasmonics has announced a partnership with Velocys, another Houston company, on its first-of-its-kind sustainable aviation fuel (SAF) production project in Uruguay.

Velocys was selected to 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 estimates that the project, known as NovaSAF 1, will produce over 350,000 gallons of SAF annually. It is backed by Uruguay’s largest dairy and agri-energy operations, Estancias del Lago, with permitting and equipment sourcing ongoing. Syzygy hopes to start operations by 2027.

"This project proves that profitable SAF production doesn't have to wait on future infrastructure," Trevor Best, CEO of Syzygy Plasmonics, said in a news release. "With Velocys, we're bringing in a complete, modular solution that drives down overall production costs and is ready to scale. Uruguay is only the start."

The NovaSAF 1 facility will convert dairy waste and biogas into drop-in jet fuel using renewable electricity and waste gas via its light-driven GHG e-Reforming technology. The facility is expected to produce SAF with at least an 80 percent reduction in carbon intensity compared to Jet A fuel.

Syzygy will use Velocys’ microFTL technology to convert syngas into high-yield jet fuel. Velocys’ microFTL will help maximize fuel output, which will assist in driving down the cost required to produce synthetic fuel.

"We're proud to bring our FT technology into a project that's changing the game," Matthew Viergutz, CEO of Velocys, added in the release. "This is what innovation looks like—fast, flexible, and focused on making SAF production affordable."

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.

How this Houston expert helps startups turn AI hype into real impact

now streaming

Artificial intelligence is now everywhere. It is mentioned in every startup pitch deck, and every corporate roadmap claims to use it. However, many early-stage businesses struggle with the simple question, “What does AI actually mean for my business?”

In a recent podcast episode of EnergyTech Startups, Merab Momen, founder of AI CTO Services and a long time AI practitioner, explains why most founders misunderstand AI, how startups can practically apply it and why Houston is quietly becoming a serious hub for AI-driven innovation.

Filling the AI Leadership Gap

Merab’s career has spanned decades of technology transitions. He worked on neutral networks in the 1990s, constructed computer vision systems long before they were common, and helped install AI solutions inside huge industrial companies. However, he noticed a huge problem when generative AI started to explode into the mainstream-The requirement of a real partner by the founders for AI integration but inability to rely on a full-time CTO and project-based consultants.

“I really needed something which is much more engaging where I can give that partner-level advice to the founders,” he said. By giving firms on-demand access to high-level AI knowledge and expertise, his methodology enables them to analyse tools, steer clear of cost blunders and eventually transition to a permanent technology leader when the time is right.

AI is Older than Most People Think

Despite its recent rise in popularity, AI is nothing new. AI actually began in the 1950s. Merab in his conversation explained how he worked on his first AI project back in the year 1996 that worked perfectly, but the processing power wasn’t just there to make it practical. He continued how he utilized the swarm intelligence models to optimize supply chains, now referred to as MLPOs and data engineering.

From Language Models to Physical World

Much of the public conversation about AI revolves around chatbots and text generation. But Merab sees far greater potential in AI’s interaction with the physical world, especially in industrial settings. He emphasized edge computing and vision language models (VLMs) as significant advances in manufacturing and energy. This physical shift is opening doors for new opportunities for robotics, automated inspections, and industrial safety applications. Merab added that Houston is uniquely positioned for this transition.

Why Houston has an AI Advantage

Silicon Valley may dominate the AI headlines, but Merab believes Houston’s advantage lies beneath the surface. The city doesn’t lag in AI utilization; it just operates in industries where results show differently.

Machine learning isn’t new to Houston’s core industries. Energy companies, manufacturers, logistics providers, and healthcare systems have been using advanced analytics for decades. The difference lies in them innovating in industrial sectors rather than consumer technology.

What’s Next

With the AI CTO Services growing, Merab is working with startups across industries to deploy AI in practical, business-first ways.

He is more interested in assisting founders in finding answers to critical issues than following new trends.

For Houston’s energy and climate tech community, it needs to transform AI enthusiasm into real-world impact.
