Wohland, J.; Witthaut, D.; Schleussner, C. (2018): Negative emission potential of Direct Air Capture powered by renewable excess electricity in Europe. In: Earth’s Future. DOI: 10.1029/2018EF000954.
„Our results show that negative emissions of up to 500 MtCO2/y in Europe may be achievable by using renewable excess energy only. Electricity systems with high shares of volatile renewables will induce excess generation events during which electricity is cheap thereby lowering the operational costs of DAC. If investment costs can be sufficiently reduced, this may render very energy intensive but highly flexible technologies such as DAC viable.“
