DACS may provide an option for handling unavoidable CO2 emissions. Its development and effective deployment depends on several factors, including the availability of suitable storage sites, sufficient amounts of renewable energy, engagement by economoic actors, an unambiguous legal framework, and infrastructures allowing the transport of captures CO2 to storage sites. However, DACS technologies have the potential to contribute to the transformation of the energy system and society at large. Sub-project III assesses macro-economic effects of a broad roll-out, societal acceptance and the needed legal framework.
