Gevo’s isobutanol good for blends of up to 16.1% in marine engines

February 16, 2015 |

In Colorado, testing on Gevo’s renewable isobutanol in marine engines has concluded after four years. The tests, performed by a consortium of leading organizations from the recreational marine industry, have showed that isobutanol blends of up to 16.1% can be used in marine engines without deterioration of engine or boat performance.

The consortium tested many engine technologies from several engine and boat manufacturers, and included measurements of gaseous and particulate engine exhaust emissions, combustion analysis, cold start, run ability, durability and more. No engine exhaust emissions failures, durability issues or run ability issues were experienced during the multi-year test program.

“This data reconfirms that the properties of isobutanol make it an excellent renewable blendstock for the marine market. We are excited to supply renewable isobutanol for marine and off-road applications and we look forward to growing this market with many of the participants from the consortium,” said Dr. Patrick Gruber, Gevo’s Chief Executive Officer.
