Green Plains, Tallgrass and PNNL are receiving DOE funding to


OMAHA, Neb., Sept. 06, 2022 (GLOBE NEWSWIRE) — Green Plains Inc. (NASDAQ: GPRE), Tallgrass, and Pacific Northwest National Laboratory (PNNL) today announced they have secured funding from the U.S. Department of Energy (DOE) to advance sustainable aviation fuels (SAF) technology as part of the federal agency’s efforts to support the development of valuable biofuels and bioproducts for the clean energy economy.

“Developing and deploying new technologies to produce sustainable aviation fuel is part of Green Plains’ ongoing transformation and this grant will help fund catalyst optimization that can lead to a pilot installation and beyond” , said Todd Becker, president and CEO of Green Plains. . “We believe that PNNL technology can be a game-changer by efficiently converting low-carbon alcohol into sustainable aviation fuel.”

The DOE award will support Green Plains and Tallgrass in funding the demonstration of an innovative process developed by PNNL to convert ethanol to SAF via ketone intermediates, a critical step in proving the scalability of the technology. Green Plains and Tallgrass currently hold the exclusive license option for the PNNL SAF technology globally. They will jointly pursue the production of SAF from cellulosic ethanol and corn and intend to commercialize the production process of PNNL once the pilot project is successfully completed.

“New alcohol-jet pathways are needed to meet the ambitious volume goals for SAF, and our rapidly evolving biorefinery platform is well positioned to help meet and exceed these goals,” added Becker. “Our collaboration with Tallgrass and our work with PNNL on advanced technologies puts Green Plains at the forefront of SAF commercialization, supported by the expansion of the policy of economic development and deployment of new SAF technology. “

“This partnership represents the type of cross-industry collaboration needed to rapidly achieve meaningful decarbonization,” said Matt Sheehy, President and CEO of Tallgrass. “At Tallgrass, we believe in developing and investing in infrastructure to produce and transport the next generation of clean fuels. We are excited to work alongside Green Plains and PNNL to advance this pioneering SAF production technology and the infrastructure to commercialize SAF production at scale.
