"Start-up of the electrolyzer is imminent and the company intends to purchase renewable energy certificates to pair with the start-up to enable green ammonia production," CF Industries said. CF Industries said it will have additional low-carbon ammonia at the Donaldsonville plant beginning in 2025 when a large-scale carbon capture and sequestration project at the facility begins. With significant potential for ethanol producers and farmers to supply future sustainable aviation fuel plants with feedstocks, the ethanol industry is tasked with reducing its carbon footprint to become a more viable SAF feedstock.
