Simon (2023): Material flows and embodied energy of direct air capture: A cradle-to-gate inventory of selected technologies

Balint Simon IN: Journal of Industrial Ecology,

The present study analyzes three selected DAC technologies: Amine-based adsorption and absorption, as well as alkali-based absorption. The parametrized model includes over 60 parameters, resulting in an array of possible energy and material requirements. The use of this wide range of figures in life cycle assessment (LCA) sheds light on real opportunities for DAC in future product systems.
