Gevo's Low Carbon, Renewable Isobutanol Program a Success in Lowering Greenhouse Gas Emissions in Seattle's Fleet Vehicles

ENGLEWOOD, Colo., Aug. 07, 2019 (GLOBE NEWSWIRE) -- Gevo, Inc. (NASDAQ: GEVO) announced today the successful completion of the City of Seattle's Phase I trial pilot of fleet vehicles utilizing Gevo's low carbon, renewable drop-in isobutanol blended gasoline to reduce greenhouse gas emissions form its fleet of vehicles.

The City confirmed they saw 18 metric tons of carbon reduction during the Phase I pilot trial using Gevo’s low carbon, renewable fuel and zero adverse effects to their fleet vehicles.

The trial, initially set to last four months, focused on the effects of the renewable blended fuel in four standard combustible engines vehicles. The positive testing results were quickly realized. All fleet vehicles housed at Seattle's Cedar Falls Fleet location were moved into the program, monitored by the on-site maintenance team and used Gevo’s blended fuel.  "The outcome of the trial was overwhelmingly positive. The testing vehicles saw no adverse effects on their engines, filters, driving performance, driver satisfaction, nor the existing fuel pipelines. We are now ready to move to a higher blended fuel and begin Phase II ahead of schedule." said, Timothy J. Cesarek, Chief Commercial Officer of Gevo. 

Philip Saunders, the City of Seattle's Green Fleet Manager, continues to support the City's top goals to reduce emissions by 50 percent by 2025 for the Seattle fleet and be fossil fuel-free by 2030. To do this, the City is focusing on three major undertakings: fleet electrification, reduction in fossil fuel use, and using fossil-free fuels as much as possible. These must all coincide together to stay on budget and to capture true environmental benefits.  Mr. Cesarek added, "Seattle takes great pride in being a leader in green fleet management. Phillip and his team are continuously researching and implementing green fleet initiatives to reduce the City's greenhouse gas emissions. We are proud to be a part of this important equation."

Patrick R. Gruber, Chief Executive Officer of Gevo, said, "This pilot  with the City of Seattle has shown the measurable reduction in pollution with a renewable blended fuel. Imagine replacing the whole gallon of gasoline with low-carbon renewable gasoline that has high performance, yet would reduce pollution and improve air quality more significantly."
