Gevo and HCS Group Sign Strategic Agreement to Produce Renewable Low-Carbon Chemicals and Sustainable Aviation Fuel in Europe

ENGLEWOOD, Colo., Feb. 24, 2021 (GLOBE NEWSWIRE) — Gevo, Inc. (“Gevo”) (NASDAQ: GEVO), announced today that Gevo and HCS Group GmbH, a long-time customer of Gevo, have signed a project memorandum of understanding (“MOU”) to develop and build a renewable hydrocarbon facility at HCS Group’s site located in Speyer, Germany, which would utilize Gevo’s low-carbon sustainable aviation fuel (“SAF”) technology.The MOU anticipates a first project that is estimated to produce approximately 60 kMT (22 million gallons per year) of renewable hydrocarbons, advanced renewable fuels, and low-carbon SAF at HCS Group’s Speyer site by the end of 2024. The HCS Group manufacturing center, operated by the Haltermann Carless brand, is strategically located in the geographical center of Europe, at the Rhine river and in the vicinity of Frankfurt airport, offering excellent prerequisites for supplying customers in Europe with SAF, certified under Europe’s Renewable Energy Directive (“EU REDII”), and a portfolio of certified renewable drop-in fuels and specialty chemicals.About GevoGevo’s mission is to transform renewable energy and carbon into energy-dense liquid hydrocarbons. These liquid hydrocarbons can be used for drop-in transportation fuels such as gasoline, jet fuel, and diesel fuel, that have the potential to yield net-zero greenhouse gas emissions when measured across the full lifecycle of the products. Gevo uses low-carbon renewable resource-based carbohydrates as raw materials from residues and slurries, and is in an advanced state of developing renewable electricity and renewable natural gas for use in production processes, resulting in low-carbon fuels with substantially reduced carbon intensity (the level of greenhouse gas emissions compared to standard petroleum fossil-based fuels across their lifecycle) and GHG scores. Gevo’s products perform as well or better than traditional fossil-based fuels in infrastructure and engines, but with substantially reduced greenhouse gas emissions. In addition to addressing the problems of fuels, Gevo’s technology also enables certain plastics, such as polyester, to be made with more sustainable ingredients. Gevo’s ability to penetrate the growing low-carbon fuels market depends on the price of oil and the value of abating carbon emissions that would otherwise increase greenhouse gas emissions. Gevo believes that its proven and patented technology, which enables the use of a variety of low-carbon sustainable feedstocks to produce price-competitive low carbon products such as gasoline components, jet fuel, and diesel fuel, yields the potential to generate project and corporate returns that justify the build-out of a multi-billion-dollar business.Learn more at Gevo’s website: www.gevo.comAbout HCS Group and Haltermann Carless
