Economic and Market Analysis of CO2 Utilization Technologies – Focus on CO2 derived from North Dakota lignite

Based on information obtained about the technical aspects of the technologies, several challenges are expected to be faced by any potential CO 2 utilization technologies intended for North Dakota lignite plants. The weather, alkaline content of lignite fly ash, and space limitations in the immediate vicinity of existing power plants are challenging hurdles to overcome. Currently, no CO 2 utilization option is ready for implementation or integration with North Dakota power plants. Mineralization technologies suffer from the lack of a well-defined product and insufficient alkalinity in lignite fly ash. Algae and microalgae technologies are not economically feasible and will have weather- related challenges.
