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.

Houston startup debuts sustainable, bio-based 'leather' fashions

sustainable fashion

Last month, Houston-based Rheom Materials and India’s conscious design studio Econock unveiled a collaborative capsule collection that signaled more than just a product launch.

Hosted at Lineapelle—long considered the global epicenter of the world's premier leather supply chain—in the vaulted exhibition halls of Rho-Fiera Milano, the collection centered around Rheom’s 91 percent bio-based leather alternative, Shorai.

It was a bold move, one that shifted sustainability from a concept discussed in panel sessions to garments that buyers could touch and wear.

The collection featured a bomber-style jacket, an asymmetrical skirt and a suite of accessories—all fabricated from Shorai.

The standout piece, a sculptural jacket featuring a funnel neck and dual-zip closure, was designed for movement, challenging assumptions about performance limitations in bio-based materials. The design of the asymmetrical skirt was drawn from Indian armored warrior traditions, according to Rheom, with biodegradable corozo fasteners.

Built as a modular wardrobe rather than isolated pieces, the collection reflects a shared belief between Rheom and Econock in designing objects that adapt to daily life, according to the companies.

The collection was born out of a new partnership between Rheom and Econock, focused on bringing biobased materials to the market. According to Rheom, the partnership solves a problem that has stalled the adoption of many next-gen textiles: supply chain friction.

While Rheom focuses on engineering scalable bio-based materials, New Delhi-based Econock brings the complementary design and manufacturing ecosystem that integrates artisans, circular materials and production expertise to translate the innovative material into finished goods.

"This partnership removes one of the biggest barriers brands face when adopting next-generation materials,” Megan Beck, Rheom’s director of product, shared in a news release. “By reducing friction across the supply chain, Rheom can connect brands directly with manufacturers who already know how to work with Shorai, making the transition to more sustainable materials far more accessible.”

Sanyam Kapur, advisor of growth and impact at Econock, added: “Our partnership with Rheom Materials represents the benchmark of responsible design where next-gen materials meet craft, creativity, and real-world scalability.”

Rheom, formerly known as Bucha Bio, has developed Shorai, a sustainable leather alternative that can be used for apparel, accessories, car interiors and more; and Benree, an alternative to plastic without the carbon footprint. In 2025, Rheom was a finalist for Startup of the Year in the Houston Innovation Awards.

Shorai is already used by fashion lines like Wuxly and LuckyNelly, according to Rheom. The company scaled production of the sugar-based material last year and says it is now produced in rolls that brands can take to market with the right manufacturer.

Houston energy co. names new COO to scale offshore decommissioning

new hire

Houston-based Promethean Energy has named a new COO as it looks to scale.

Martyn Fear, former CEO of Altamesa Energy Canada Inc., will assume the role, the company announced last week. He brings decades of experience at energy companies such as BP and Maersk Oil and has held board positions at several private equity and venture-backed firms.

“Promethean has built a differentiated platform for managing and retiring late-life assets safely, efficiently, and responsibly,” Fear said in a news release. “The industry is facing a structural shift as decommissioning moves to the forefront, and the opportunity to combine operational excellence, disciplined project delivery, and innovative commercial models is incredibly compelling."

Promethean has developed an environmentally sustainable, integrated model for late-life asset management and offshore well decommissioning. Fear will oversee day-to-day operations at Promethean and the execution of this integrated operator-service model as the company looks to scale and expand to new markets.

“Martyn is a proven leader with a deep operational track record and a passion for building high-performance, safety-first organizations,” Aditya Singh, Promethean's CEO, added in the release. “As Promethean enters its next phase—scaling our integrated operator-service model and delivering first-time-right decommissioning at pace—his experience in transforming complex asset portfolios and leading global teams makes him the ideal COO to drive operational execution while we continue to advance our strategic vision.”

Last May, the company successfully decommissioned offshore orphaned wells in the Matagorda Island lease area. In November, it also announced that it had completed a multi-client project to safely plug and abandon an orphaned well on a storm-damaged platform in the South Timbalier lease area.

Both projects were based in the Gulf of Mexico, where Promethean is looking to grow.
