As the aviation industry seeks low carbon fuels, attention has come to making biofuels into jet fuel.

It’s called sustainable aviation fuel, and it can be made from corn and soybeans. Governor JB Pritzker says a recently passed tax credit is designed to incentivize the use of it at the state’s airports.

SAF is short for sustainable aviation fuel. O’Hare in Chicago see’s 55 million passengers move through the airport each year and Illinois is home to two of the nation’s top 15 airports for freight transportation.
