The project is organized in four interlinked sub-projects. Sub-project I ‘technology assessment’ identifies optimal sites around the world for the operation DACS based on techno-economic analysis and sustainability assessment. Sub-project II ‘device research,’ develops several technical DAC options and prepares their large-scale implementation. Sub-project III ‘transformational studies’ conducts stakeholder analysis and technology acceptance analyses, and investigates the current and required regulatory framework to enable a sustainable ramp-up.
