Gevo ATJ-30 Richardton / Project North Star

Gevo ATJ-30 (Project Northstar) is a planned 30 million gallon per year Alcohol-to-Jet Sustainable Aviation Fuel facility to be co-located at Gevo North Dakota's Richardton, ND site alongside the existing corn ethanol plant (former Red Trail Energy assets) and its operational Class VI CCS well. The facility will consume approximately 50 MMGPY of on-site ethanol as feedstock and produce ASTM D7566 Annex A5 jet fuel plus renewable diesel and naphtha coproducts using Gevo's proprietary integrated ATJ process, including the newly-patented Ethanol-to-Olefins (ETO) technology (US Patent No. 12,486,207 B2, awarded January 14, 2026) that is expected to deliver up to 35% lower capital and operating costs versus current technologies. FEL-3 engineering was completed in July 2026 with a total capital cost estimate of approximately $600 million (±10%); the underlying alcohol-to-jet process modules came in within 2% of the FEL-2 estimate and are not site-specific, enabling repeatable "Copy-Edit-Paste" deployment at future sites. Gevo is developing ETO with LG Chem for renewable chemical applications and with Axens and IFP Energies nouvelles (IFPEN) for fuel applications, with Axens expected to provide global licensing, equipment, and engineering services. On April 15, 2026, Gevo withdrew its loan guarantee application from the U.S. Department of Energy's Office of Energy Dominance Financing (EDF, formerly the Loan Programs Office), which had previously issued a conditional commitment for the earlier ATJ-60 project at Lake Preston, South Dakota (Net-Zero 1).
