Summary/Abstract
This article identifies DAC is an enabling technology useful for carbon dioxide removal, first, as direct air carbon capture and storage (DACCS) and second, as CO2 utilization (DACCU) for fuels in the transport sector, in particular marine, aviation, and the chemical industry. The article discusses how investment into DAC is an essential precondition for a continued development and cost-scaling. but in particular for a stable market ramp-up for for DACCU applications, and also for CCS/ CDR solutions. The fundamental learning from the solar photovoltaics case in the 2000s and 2010s is that forward looking policies, in particular the Feed-in Tariff legislation in Germany, a form of regulation, and substantial manufacturing scale-up backed with guarantees, as practiced in China, can accelerate technology deployment and diffusion by decades .
