Recently, CF Industries and POET announced a collaboration to launch an innovative pilot project in the United States, producing low-carbon ethanol through low-carbon fertilizer production. By establishing a low-carbon value chain from agriculture to energy, the project aims to promote the sustainable development of the biofuel industry. The initiative involves multiple agricultural cooperatives to build a low-carbon fertilizer supply chain, with the pilot covering four states: Iowa, Minnesota, Missouri, and Nebraska. Among these, CF Industries produces low-carbon ammonia at its Donaldsonville plant using carbon capture and storage technology, with an annual production capacity of 1.9 million tons, sufficient to meet the fertilizer needs for corn cultivation across 19 to 22 million acres. In the fall of 2025, the project completed the first sales and field application of low-carbon ammonia fertilizer. POET will process corn grown with this low-carbon fertilizer at its biofuel plants in Minnesota, Iowa, and Nebraska, with an estimated production of 5 to 6 million gallons of low-carbon-intensity ethanol. Bert Frost, Commercial President of CF Industries, stated that low-carbon fertilizer provides a quantifiable and certifiable solution for decarbonizing the bioethanol feedstock stage. Christian McIlvain, President of Grain Business at POET, also noted that this collaboration opens a new pathway for reducing the carbon intensity of ethanol, offering both environmental and economic benefits. Both parties emphasized that this pilot represents deep collaboration between agriculture and energy enterprises, providing a practical model for the low-carbon transformation of the biofuel industry chain.
