Young People's Burden: Requirement of Negative CO2 Emissions (2016, neutral): “, 2015), and (2) direct air capture of CO2 and sequestration (Keith, 2009; NAS, 2015a), and (3) grinding and spreading of minerals such as olivine to enhance geological weathering (Taylor et al.”
Response to ‘Burden of proof: A comprehensive review of the feasibility of 100% renewable-electricity systems’ (2017, background): “promising for the production of synthetic fuels [29, 202, 203] and is attractive because of its locational flexibility and minimal water consumption [204, 205].”
The road to achieving the long-term Paris targets: energy transition and the role of direct air capture (2017, methodology): “We assume that the DAC technology is available from 2060 (following Chen and Tavoni 2013) with an initial cost of 600 US$2010/tCO2 captured and a floor cost of 200 US$2010/tCO2, covering the ranges in the literature (see Table SOM3).”
Soil carbon sequestration and biochar as negative emission technologies (2016, background): “, 2001), (ii) direct air capture of CO2 from ambient air by engineered chemical reactions (DAC; Keith, 2009; Socolow et al., 2011), (iii) enhanced weathering of minerals (EW; Schuiling & Krijgsman, 2006; K€ ohler et al.”
Techno-Economic Assessment for CO2 Capture From Air Using a Conventional Liquid-Based Absorption Process (2020, background): “…(in fact it can capture 100% of CO2 emission to the atmosphere), for capturing dispersed fugitive emissions, and for direct use in different industries such as beverage, greenhouse, and synthetic fuels production industries (Lackner et al., 1999; Keith, 2009; Lackner, 2009; Krekel et al., 2018).”
The feasibility of low CO2 concentration targets and the role of bio-energy with carbon capture and storage (BECCS) (2010, background): “The option negative emission technologies—be it BECCS or the direct capture of CO2 from the air (see Keith 2009)—makes it, from a purely physical point of view, possible to postpone emission reduction in the near term and compensate that by removing CO2 some time later in the future and still meet…”
