: Direct air capture (DAC) is an essential nexus of CO2 chemistry and climate mitigation. Life cycle assessment (LCA) is often deployed to validate the environmental potentials of such future emerging technologies. Consequently, an increased number of ex-ante LCAs are expected in this field. However, recently a comprehensive life cycle inventory for LCA is missing from the international literature, which is essential for transparency. To fill this gap, the present paper analyses three selected DAC technologies to create an inventory for LCAs. Amine-based adsorption and -absorption, as well as, alkali-based absorption was modelled. Energy consumption of the operation, the cradle-to-gate embodied energy and sensitivity analysis based on parameter variations were carried out. The maximum energy released by the formation of CO2 (8.94-18.2 GJ/t CO2) were also considered in the evaluation. However several studies state that DAC is a negative emission technology, its energy requirement often lies in the range or above the formation energy of CO2. Accordingly, theoretically more energy is required for the capture as can be obtained during the formation of CO2. The calculation model includes over 60 parameters resulting in an array of the possible energy and material requirements. The use of this wide range of figures in life cycle assessment sheds light on the real opportunities of direct air capture in future product systems. The option of varying parameters enables tailoring the calculation to a particular situation or design. In this way, the calculator offers a common base for LCA fostering the early-stage analysis of DAC technologies.

The carbon dioxide capture is a more and more important issue in the design and operation of boilers and/or power stations because of increasing environmental considerations. Such processes, absorber desorber should be able to cope with flue gases from the use of different fossil primary energy sources, in order to guarantee a flexible, stable, and secure energy supply operation. The changing flue gases have significant influence on the optimal operation of the capture process, that is, where the required heating of the desorber is the minimal. Therefore special considerations are devoted to the proper design and control of such boiler and/or power stations equipped with CO2 capture process.

Direct air capture (DAC) is an essential nexus of CO 2 chemistry and climate mitigation. Life cycle assessment (LCA) is often used to validate the environmental potential of emerging technologies. Consequently, an increased number of ex ante LCAs is expected in this field. However, a comprehensive description through parameterized modeling of life cycle inventories of distinct technological pathways, which is essential for transparency, has recently been missing from the international literature. To fill this gap, the present study analyzes three selected DAC technologies to create an inventory. Amine-based adsorption and absorption, as well as alkali-based absorption, were modeled.The energy consumption of the operation, cradle-to-gate embodied energy, and sensitivity analysis based on parameter variations were carried out. The "cradle-to-gate" energy requirement of direct air capture (DAC) often lies in the range or above the formation energy of CO 2 (8.94 GJ energy can be obtained by formation of 1 t CO 2 from elementary C and O 2 ). This indicates that theoretically more energy is required for capture, as can be obtained during the formation of CO 2 . Because energy has continuously growing economic and ecological value, this energy intensity of DAC implies that DAC might have important role in CCU to add directly measurable economic value.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.The option of varying parameters enables the tailoring of the calculation to a particular situation or design. In this way, the calculator offers a common base for LCA, fostering an early stage analysis of DAC technologies.
