In Tennessee, University of Tennessee researchers have been using captured carbon dioxide as a feedstock for producing useful fuels and chemicals. The work focuses on developing technologies that can transform CO₂ rather than simply storing it, potentially creating a pathway that combines carbon management with renewable-fuel production. The research remains at the technology-development stage, however, […]
In Tennessee, FedEx is scaling its sustainable aviation fuel (SAF) procurement through new agreements projected to secure more than 20 million gallons of neat SAF across five U.S. airports through calendar year 2027. The agreements span FedEx operations at Newark Liberty International Airport (EWR), Oakland International Airport (OAK), Miami International Airport (MIA), John F. Kennedy […]
In Tennessee, the University of Tennessee, Knoxville, is part of a team that has won up to $160 million over the next 10 years from the National Science Foundation for the BRIDGES Engine, a collaborative initiative that will generate millions of dollars in additional annual income for Tennessee farmers and create thousands of jobs across […]
In Tennessee, the University of Tennessee, Knoxville, and its partners have secured up to $160 million over 10 years from the National Science Foundation to launch the BRIDGES Engine, a biobased manufacturing initiative focused on economic growth in Tennessee and Alabama. One of 12 winners in NSF’s Regional Innovation Engines competition, BRIDGES will transform underused […]
In Tennessee, precision fermentation startup Melazyme has raised $2 million in a seed funding round to support platform development and production scale-up of high-value molecules like melanin and brazzein. The company was founded in 2025 by Perumal Gandhi and Bonney Oommen, two veterans of cultivated dairy protein firm Perfect Day. Melanin has applications across cosmetics […]
In Tennessee, Trillium Renewable Chemicals (Trillium) has raised a $13 million Series B financing round. The financing was led by HS Hyosung Advanced Materials with participation from Capricorn Partners. This funding builds on the company’s previous $10.6 million Series A financing round and non-dilutive $2.5 million award from the U.S. Department of Energy. Following a successful multi-year pilot program […]
In Tennessee, Bridgestone Americas (Bridgestone) and Penske Transportation Solutions (Penske) announced the findings of the first phase of their shared initiative, the Decarbonization Lab (Lab). The Lab was designed to identify and validate commercially viable, near-term solutions that help reduce CO₂ emissions for commercial fleets under real-world conditions. Penske and Bridgestone plan to continue refining […]
In Tennessee, Gevo has licensed two patented catalyst technologies from the U.S. Department of Energy’s (DOE) Oak Ridge National Laboratory (ORNL) for use in the production of sustainable aviation fuel (SAF). Researchers at ORNL developed catalysts that enable a single-step conversion of ethanol to olefins (ETO), which can then be used to produce SAF. A catalyst accelerates chemical reactions and enhances the efficiency of the fuel production process. In addition to SAF, olefins serve as key building blocks for a wide range […]
In Tennessee, FIDEM Energy LLC announced a strategic partnership with Japan-based Sojitz Corporation to advance U.S. renewable natural gas (“RNG”) production. Based in East Tennessee, FIDEM produces and markets RNG generated from landfill gas. FIDEM’s management team has decades of experience in operating solid waste management landfills across the Southeastern United States. Currently, FIDEM owns […]
In Tennessee, Chattanooga’s Moccasin Bend Environmental Campus is launching a project that will generate electricity from wastewater methane, a move expected to significantly reduce the campus’s roughly $300,000 monthly energy costs while turning a treatment byproduct into a reliable on-site energy source. The Mainspring system will allow MBEC to produce much of its electricity on-site, […]
