The sub-project, ‘technology assessment’ conducts a holistic assessment of DACS technology. In its course the techno-economic potential of DACS is demonstrated globally. Furthermore, globally-available and -suitable underground storage potential with consideration of constraints is identified. In addition, the various impacts connected to the implementation of DACS systems are investigated. This includes the impact of emissions from DAC facilities, including adsorbent degradation products and on the atmosphere. A technology-path-specific assessment of entire process chains will determine the sustainability (ecologic, economic and social) of different DACS systems. Finally, the interdisciplinary knowledge gathered about DACS technology from the previous assessments is combined to allow a detailed design of a sustainable DACS system for specific sites. This way the sub-project allows to recommend suitable sites and DACS system setups for pilot projects and a subsequent market ramp-up of this technology.
