Following supply problems experienced in the U.K. in 2018 and again in 2021, the U.S. may also be facing a shortage of available carbon dioxide for industries including brewing, beverages and food processing.  Currently, large-scale users are scrambling to lock-in contracts with producers, including ethanol plants.  At the present time, many ethanol plants are venting the greenhouse gas into the atmosphere or, in some cases, are sequestering it in soil beneath their plants.  A number of pipeline companies have proposed pipeline projects to collect carbon dioxide from Midwest ethanol plants, to be conveyed to central points where the gas will be injected deep into soil. 

It would appear that carbon dioxide is in demand and with an anticipated increase in price, suitable investment to technology to capture, store and transport the gas will create additional availability.
