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 scientists create first profile of Mars’ radiant energy budget, revealing climate insights on Earth

research findings

Scientists at the University of Houston have found a new understanding of climate and weather on Mars.

The study, which was published in a new paper in AGU Advances and will be featured in AGU’s science magazine EOS, generated the first meridional profile of Mars’ radiant energy budget (REB). REB represents the balance or imbalance between absorbed solar energy and emitted thermal energy across latitudes. An energy surplus can lead to global warming, and a deficit results in global cooling, which helps provide insights to Earth's atmospheric processes too. The profile of Mars’ REB influences weather and climate patterns.

The study was led by Larry Guan, a graduate student in the Department of Physics at UH's College of Natural Sciences and Mathematics under the guidance of his advisors Professor Liming Li from the Department of Physics and Professor Xun Jiang from the Department of Earth and Atmospheric Sciences and other planetary scientists. UH graduate students Ellen Creecy and Xinyue Wang, renowned planetary scientists Germán Martínez, Ph.D. (Houston’s Lunar and Planetary Institute), Anthony Toigo, Ph.D. (Johns Hopkins University) and Mark Richardson, Ph.D. (Aeolis Research), and Prof. Agustín Sánchez-Lavega (Universidad del País, Vasco, Spain) and Prof. Yeon Joo Lee (Institute for Basic Science, South Korea) also assisted in the project.

The profile of Mars’ REB is based on long-term observations from orbiting spacecraft. It offers a detailed comparison of Mars’ REB to that of Earth, which has shown differences in the way each planet receives and radiates energy. Earth shows an energy surplus in the tropics and a deficit in the polar regions, while Mars exhibits opposite behavioral patterns.

The surplus is evident in Mars’ southern hemisphere during spring, which plays a role in driving the planet’s atmospheric circulation and triggering the most prominent feature of weather on the planet, global dust storms. The storms can envelop the entire planet, alter the distribution of energy, and provide a dynamic element that affects Mars’ weather patterns and climate.

The research team is currently examining long-term energy imbalances on Mars and how it influences the planet’s climate.

“The REB difference between the two planets is truly fascinating, so continued monitoring will deepen our understanding of Mars’ climate dynamics,” Li says in a news release.

The global-scale energy imbalance on Earth was recently discovered, and it contributes to global warming at a “magnitude comparable to that caused by increasing greenhouse gases,” according to the study. Mars has an environment that differs due to its thinner atmosphere and lack of anthropogenic effects.

“The work in establishing Mars’ first meridional radiant energy budget profile is noteworthy,” Guan adds. “Understanding Earth’s large-scale climate and atmospheric circulation relies heavily on REB profiles, so having one for Mars allows critical climatological comparisons and lays the groundwork for Martian meteorology.”
