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.”

Houston renewable energy developer continues growth in New York with 10 new solar projects

shine on

A Houston renewable energy developer has announced 10 new projects in partnership with a New York company.

Catalyze selected GreenSpark Solar — an engineering, procurement, and construction company — to work on 10 new renewable energy projects totaling 60 megawatts.

“We’re excited to expand our solar portfolio through this partnership with GreenSpark, which has been a leader in the New York renewable energy landscape for over two decades now,” Jared Haines, CEO of Catalyze, says in a news release. “We look forward to sharing our mutual expertise to provide New Yorkers with affordable and reliable renewable electricity, regardless of geography or income.”

The projects, which are expected to deliver this year through mid 2025, will be funded in part by the New York State Energy Research and Development Authority through the NY-Sun Program. The state has a goal of installing 10 gigawatts of distributed solar and reaching 70 percent renewable energy by 2030, per the release.

“Community solar is one of the best avenues to bring the energy transition to low-middle income communities—a movement that GreenSpark is incredibly passionate about,” adds Kevin Schulte, CEO of GreenSpark Solar. “We are excited to support Catalyze’s success in bringing community solar projects online across New York and look forward to supporting them to bring this portfolio of solar projects to fruition, and in turn, bring more renewable energy to our communities.”

The deal follows Catalyze's May announcement that it secured $100 million in financing from NY Green Bank to support a 79 megawatt portfolio of community distributed generation solar projects across the state of New York.

Catalyze also announced another partnership earlier this month with real estate leader Cushman & Wakefield to expand installation of solar panels and battery storage technology at U.S. commercial and industrial properties.

Solar manufacturer announces massive new facility in Houston area

coming soon

SEG Solar has announced plans to open a new 1.15 million-square-foot solar module facility in Tomball—its third in the Houston area.

The news comes just weeks after the Houston-based solar manufacturer announced its second facility, which will be located in Cypress. It’s expected to open in August.

The latest 4.6-gigawatt facility in Tomball will include an assembly factory and a warehouse. Construction is slated to wrap in March 2027, with commercial panel production planned to begin in May 2027. Once completed, the facility will bring SEG’s annual U.S. module manufacturing capacity to 10.6 gigawatts, according to a news release from the company, one of the largest totals in the country.

The facility will produce heterojunction technology (HJT) modules, which the company says will add to the number of n-type solar panels made in the U.S. HJT modules are known to be more durable and are well suited for hotter climates.

“Designed to support next-generation HJT technology and FEOC-compliant production, the facility ensures reliable, high-efficiency solar solutions,” Raymond Bailey, sales manager at SEG Solar, said in a LinkedIn post. “ Alongside upstream integration in Indonesia and potential U.S. cell manufacturing, we are strengthening supply chain resilience amid evolving trade policies.”

SEG opened its $60 million, 250,000-square-foot facility in Houston in 2024 to house its production workshops, raw material warehouses, administrative offices, finished goods warehouses, and supporting infrastructure. The continued expansion is part of SEG’s long-term goal of becoming one of the largest 100 percent U.S.-owned module manufacturers.

Houston chemical co. completes successful field trial of cleaner natural gas processing tech

successful trial

Houston-based Merichem Technologies has announced successful results from the field trial of its new hydrogen sulfide (H2S) removal technology in the Permian Basin.

The technology, known as ECOTREAT, removed more than 99 percent of hydrogen sulfide gas from natural gas streams, or “sour gas,” without producing solid waste during the month-long trial. It also showed sustained performance even when operating above the unit’s design capacity, according to a news release.

“The industry is continually seeking to reduce both the price and complexity of removing hydrogen sulfide from gas production, especially since oil production has shifted to increasingly sour sources, higher gas ratios, and higher water ratios,” Jeff Gomach, SVP, Merichem Technologies, said in a news release. “ECOTREAT met all its field trial objectives and provides a highly effective method for removing hydrogen sulfide to prevent equipment corrosion, ensure worker safety, meet environmental regulations, and maintain product quality for transport.

H2S found in natural gas can turn the gas toxic or hazardous and lead to corrosion in pipelines and processing equipment. However, standard H2S removal technologies create high levels of solid waste. ECOTREAT resolves many of those issues by using an aqueous-phase proprietary catalytic process that converts H2S into dissolved thiosulfate.

Next, Merichem says it plans to move the technology out of the pilot stage to full-scale commercialization.

Merichem, an 80-plus-year-old company, initially launched as a soap and industrial cleaning company. It eventually transitioned to focus on energy technology.

In 2024, Black Bay Energy acquired a portion of Merichem Process Technologies and Merichem Catalyst Products, which would become Merichem Technologies.

Cemvita reaches breakthrough in sustainable fuel feedstock production

clean fuels

Houston-based biotech company Cemvita announced that it recently reached a critical milestone in the development of its FermOil product, which can be used to create Sustainable Aviation Fuel (SAF) and other renewable fuels at industrial scale.

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.”
