CO 2 direct air capture (DAC) is among the most promising negative emission technologies (NETs). The energy demands for low-temperature solid-sorbent DAC are mainly heat at around 100 °C and electricity, which lead to sustainably operated DAC systems based on low-cost renewable electricity and heat pumps for the heat supply. This analysis is carried out for the case of the Maghreb region, which enjoys abundantly available low-cost renewable energy resources. The energy transition results for the Maghreb region lead to a solar photovoltaic (PV)-dominated energy supply with some wind energy contribution. DAC systems will need the same energy supply structure. The research investigates the levelised cost of CO 2 DAC (LCOD) in high spatial resolution and is based on full hourly modelling for the Maghreb region. The key results are LCOD of about 55 €/t CO2 in 2050 with a further cost reduction potential of up to 50%. The area demand is considered and concluded to be negligible. Major conclusions for CO 2 removal as a new energy sector are drawn. Key options for a global climate change mitigation strategy are first an energy transition towards renewable energy and second NETs for achieving the targets of the Paris Agreement.","abstract_license":"CC-BY (publisher license, via OpenAlex)","license":"cc-by","is_open_access":true,"retracted":false,"peer_reviewed":null,"categories":["Carbon Dioxide Capture Technologies"],"details":null,"provenance":"openalex","attribution":"Abstract of \"Carbon dioxide direct air capture for effective climate change mitigation based on renewable electricity: a new type of energy system sector coupling\" by Christian Breyer, Mahdi Fasihi, Arman Aghahosseini, https://doi.org/10.1007/s11027-019-9847-y, used under its Creative Commons Attribution license (CC-BY); markup removed, otherwise unmodified.","topics":[{"slug":"carbon-removal","name":"Carbon Dioxide Removal","domain_slug":"energy"}],"cited_in_dossiers":[{"slug":"carbon-removal","title":"Carbon Dioxide Removal: State of the Field (October 2026)","url":"https://space-kitty.com/dossiers/carbon-removal"}]}
