Despite federal and state programs to convert corn into ethanol and soybeans into biodiesel to fuel cars and trucks, the United States has never before regarded farming as a primary energy producer.
That changed when Congress in August passed the climate provisions of the Inflation Reduction Act, which provides $140 billion in tax incentives, loans and grants to replace fossil fuels with cleaner renewable energy that lowers emissions of carbon dioxide.
Along with the wind and the sun, the raw materials needed for a significant portion of that energy come from agriculture — alcohol from fermenting corn, and methane from the billions of gallons of liquid and millions of tons of solid manure produced by big dairy, swine and poultry operations.
Despite pushback from environmental groups concerned about increased pollution from farm waste, developers across the country see opportunities to build ambitious renewable energy projects to convert crops and agricultural wastes to low-carbon energy.
“There is not a single renewable energy producer in the country that is not looking at or already taking steps to install new technology, expand their facilities, or thinking about building new plants in response to the federal tax incentives passed last year,” said Geoff Cooper, the president and chief executive of the Renewable Fuels Association, an industry trade group.
In January, Avapco, a biofuel company that operates an ethanol refinery in Thomaston, Ga., about 60 miles west of Macon, was awarded an $80 million grant by the Department of Energy to build a plant capable of producing 1.2 million gallons of jet fuel a year from wood chips. And on a 2,500-acre site near Hennepin, Ill., Marquise Energy is collaborating with LanzaJet, which makes low-carbon fuel, to build an ethanol and biodiesel plant to produce aviation fuel for jets taking off from Chicago’s two major airports.
