Cost Assessment of Direct Air Capture: Based on Learning Curve and Net Present Value

Emerging trends in direct air capture of CO2: a review of technology options targeting net-zero emissions

“…261 Economic assessment methodology of DAC and HVAC integration. In this analysis, the cost assessment has been done based on a learning-by-doing model provided by Young et al 267 for a DAC system. They found that DAC combined with renewable energy can breakeven by 2030.…”

“…The energy used in the model is provided by a combined gas cycle turbine (CCGT). The main equation used by Young et al 267 for the assessment is: processing is c p . Table 9 shows some of the input parameters used by Young et al 267 The same parameters will be considered for this study and the energy requirements will be modied.…”

“…The economic model by Young et al 267 has been modified in this paper to find the economic viability of DAC/HVAC-coupling considering the energy-saving potential of cooling. The steps taken to carry out the simplistic analysis are mentioned in Fig.…”

“…18 . The parameters for the economic assessment are kept the same as in the model by Young et al 267 and the costs for the energy saving are modified. The energy used in the model is provided by a combined gas cycle turbine (CCGT).…”

“…The energy used in the model is provided by a combined gas cycle turbine (CCGT). The main equation used by Young et al 267 for the assessment is: c = c d + c O&M = c d + c a + c e + c o + c p where c d is plant construction cost, CO&M is the operation and maintenance cost. The operations and maintenance consists of the absorbent/adsorbent cost c a and the cost of energy c e and other operations/maintenance c o , and the cost of CO 2 processing is c p .…”
