1. Highly Confidential Multiple pathways exist for low-CI fertilizer production Hydrogen Production Ammonia Production UAN Production Urea Production CO2 can be mitigated through CCS or use of green hydrogen N2 O can be mitigated through installation of catalyst CO2 Removal Natural Gas Water CO2 Process CO2 (High purity) Flue Gas CO2 N2 O Emissions Air Ammonia Urea UAN Fertilizer Products
