A new carbon capture and sequestration project at the Valero ethanol plant in Linden, Indiana, aims to store fermentation CO2 deep underground. The project uses Class VI injection wells to move carbon into saline formations, reducing the emissions profile of corn-based ethanol. While CCS lowers the carbon intensity of biofuels, critics argue that ethanol production still relies on land-intensive agriculture and releases significant greenhouse gases. The project highlights the tension between local economic reliance on biofuels and the broader goal of deep decarbonization.
