An Overview on the Ieaghg Technical Programme: CO2 Capture Technologies for the Power and Industrial Sectors, Their Integration and Potential to Reduce Costs

The first generation of carbon capture technologies has been proven to be feasible and the second generation seems to offer further enhancements. While models usually include 90% of capture rate, that can be predictably increased. In the power sector, the main focus has been the reduction in cost and energy penalty. However, many discussions on the value of CCS beyond LCOE are still ongoing as part of the future complex electricity grid in different locations. Moreover, the water consumption has been highlighted as one of the concerns for water-stressed regions and a further assessment was needed.

In the industrial sector, carbon capture technologies can tackle down process emissions which could not be reduced otherwise. However, the preferred configuration is site-specific and a tailored analysis is needed for each case of study.

To solve those concerns, IEAGHG has commissioned seven technical studies and reviews in the period 2017-2019. In this presentation, the results from the IEAGHG technical studies will be discussed, including an overview of the benchmark and emerging CO₂ capture technologies. The techno-economic analyses have shown that emerging technologies might be promising, perhaps less detailed cost assessments for low TRL technologies are published in the literature due to the lack of demonstration projects. Flexibility is key for the integration of CCS in the electricity grid and the costs and water consumption in power plants are strongly dependent on the location, due to local conditions and regulations. Moreover, it is techno-economically feasible to increase the capture rate. Those parameters will impact on the decisions for integrating and designing CCS systems. In the industrial sector, energy/steam production, and access and characteristics of the electricity grid are decisive parameters to select the CO₂ capture system configuration.
